Inference API Terms of Service

This English version is a courtesy translation. These Terms are governed by French law and the French version prevails in the event of any discrepancy. The authoritative text is the French version of this page.

Article 1 — Purpose and identity of JUST AI

These terms of service (the “Terms”) govern access to and use of the JustAI Inference API (the “Service”).

The Service is provided by JUST AI, a simplified joint-stock company (SAS) with a share capital of €2,275, registered with the Evreux Trade and Companies Registry under number 882 522 436, whose registered office is at 71 rue Marcel Paul, 27000 Evreux, France, EU VAT number FR44882522436 (“JUST AI”, “We”, “Us”).

These Terms apply, within the limits of Article 3.5, to anyone who uses the Service, either directly or, where applicable, through a Platform (the “User” or “You”). They are separate from the General Terms of Service of the Brio platform, which do not apply to the Service.

Article 2 — Definitions

• “AI Regulation”: Regulation (EU) 2024/1689 of the European Parliament and of the Council of 13 June 2024 laying down harmonised rules on artificial intelligence (the “AI Act”).
• “API Key”: a secret identifier issued by JUST AI to authenticate requests sent to the Service.
• “Content”: Inputs and Outputs.
• “Data Processing Agreement”: the data processing agreement set out in Annex 1.
• “Direct Customer”: a business that has entered into a direct access agreement for the Service with JUST AI (accepted quotation, purchase order or specific agreement).
• “GDPR”: Regulation (EU) 2016/679 of the European Parliament and of the Council of 27 April 2016 (General Data Protection Regulation).
• “Inputs”: the data You send to the Service in a request (instructions, messages, documents, images or any other content).
• “Metadata”: technical data describing a request, excluding any Content, as listed in Article 7.3.
• “Model”: an open-weight artificial intelligence model made available through the Service.
• “Outputs”: the responses generated by a Model and returned by the Service.
• “Personal Data”: any information relating to an identified or identifiable natural person, within the meaning of Article 4 GDPR.
• “Platform”: a third-party intermediary service through which JUST AI may offer the Service to that service's own customers, for example OpenRouter, operated by OpenRouter, Inc.
• “Privacy Policy”: JUST AI's privacy policy published at https://justai.fr/en/confidentialite, in particular its Article 11.
• “Publisher”: the entity that developed a Model and sets its licence, for example Qwen for the Qwen3.6-35B-A3B Model.

Article 3 — Scope and acceptance

3.1. Business use. The Service is designed for business use. JUST AI sells it directly to professionals acting in the course of their business, to whom direct access is reserved (Article 3.2); if You act on behalf of a legal entity, You represent that You have authority to bind it. JUST AI does not market the Service to consumers. If the Service is offered through a Platform (Article 3.3), JUST AI does not select that Platform's users; Article 3.4 then applies to consumers.

3.2. Direct access. A Direct Customer accepts these Terms, including the Data Processing Agreement, when entering into its agreement. The quotation or purchase order reproduces them or refers to them prominently. Specific terms agreed in writing, such as a service level agreement, prevail over these Terms in the event of conflict.

3.3. Access through a Platform. JUST AI may also offer the Service through a Platform. When You access the Service in this way:

• Your commercial relationship (sign-up, pricing, billing, payment, refunds, first-line support) is exclusively with the Platform and governed by its own terms. JUST AI does not bill You directly.
• The Platform's terms may require You to comply with the terms applicable to each model and provider, including these Terms. In any event, by sending requests to the Service, You agree to comply with the articles that apply to You under Article 3.5.
• The relationship between JUST AI and the Platform is governed by the agreement between them. In the event of conflict, that agreement prevails as between them.

3.4. Consumers. If a natural person acting for purposes outside their commercial, industrial, craft, professional or agricultural activity accesses the Service, in particular through a Platform, nothing in these Terms deprives that person of the protection afforded by the mandatory consumer protection rules applicable to them, including those of their country of habitual residence. Any provision contrary to those rules cannot be enforced against them to that extent.

3.5. Applicable articles. Articles 13 to 16, 17.2 and 17.3 and Annex 1 govern the contractual relationship between JUST AI and its Direct Customers and, where applicable and unless otherwise agreed, Platforms. All other articles apply to every User, whether accessing the Service directly or through a Platform.

Article 4 — Description of the Service

4.1. Infrastructure. The Service provides access, through an application programming interface (API), to open-weight Models run by JUST AI on GPU servers it owns. These servers are hosted in France, in colocation at the DC2SCALE data centre in Paris-Vélizy. DC2SCALE, a French operator that designs and runs its own data centres in France, provides physical hosting only, with no logical access to the servers or to data. TLS encryption terminates on these servers; no content delivery network (CDN) or anti-DDoS service decrypts traffic upstream of them. Requests are not forwarded to any third-party model provider and are not executed by any cloud provider. If these servers are unavailable, the Service rejects requests rather than failing them over to another host.

4.2. Model fidelity. JUST AI does not alter Inputs and adds no system prompt to them. Outputs are returned as generated by the Model.

4.3. Catalogue. The current list of Models is the one in the table in Article 5.4 and in the Service's technical catalogue (the API's /models endpoint). For each Model, the table states its Publisher, licence (with a link to its text) and modalities; the technical catalogue also states its version, numerical precision (“quantisation”), context length and price. JUST AI runs the Model, version and quantisation announced and keeps this information up to date.

4.4. Changes. JUST AI may change the Service (adding or withdrawing Models, new versions, technical parameters) as set out in Article 11.

Article 5 — Models and Publisher licences

5.1. Models are developed by their Publishers, who distribute them under their own licences and, where applicable, their own acceptable use policies. Unless stated otherwise in the catalogue, JUST AI is not the Publisher of the Models.

5.2. You agree to comply with the licence and acceptable use policy of each Model You use, including any provisions on the use of Outputs (for example to train another model) and on attribution.

5.3. JUST AI may suspend or withdraw access to a Model where its licence or applicable law so requires.

5.4. Available Models. The table below and the technical catalogue (Article 4.3) make up the current list of Models. JUST AI may add a Model by listing it there with its Publisher, licence and modalities. Such an addition does not amend these Terms, which apply to every Model offered, and You must comply with the licence of the added Model (Article 5.2). The withdrawal of a Model is governed by Article 11.4.

Article 6 — Acceptable use

You shall not use the Service, directly or through a third party, to:

• a) commit or facilitate an offence, or generate, disseminate or process unlawful content;
• b) generate, solicit or process any sexual content involving minors; JUST AI reserves the right to report such conduct to the competent authorities;
• c) infringe the rights of third parties, including their intellectual property rights, privacy or reputation, or process Personal Data without a legal basis;
• d) create, distribute or operate malware, phishing, fraud or spam campaigns, or gain unauthorised access to any information system;
• e) contribute to the design, manufacture or use of weapons, including chemical, biological, radiological or nuclear weapons;
• f) carry out any practice prohibited by Article 5 of the AI Regulation, including: manipulating persons or exploiting their vulnerabilities in order to materially distort their behaviour; social scoring; assessing the risk of a person committing a criminal offence based solely on profiling; emotion recognition in the workplace or in educational institutions, other than for medical or safety reasons; biometric categorisation to infer sensitive data;
• g) circumvent authentication, rate limits, quotas or any security measure of the Service, or share, assign or resell an API Key without JUST AI's written consent;
• h) attempt to extract the weights or parameters of JUST AI's own Models, or to access other users' Content;
• i) attack or probe the Service infrastructure (denial of service, scanning, exploitation of vulnerabilities), or deliberately overload it with artificial requests; any vulnerability discovered in good faith must be reported to the address given in Article 20 and must not be exploited;
• j) breach applicable economic sanctions or export control regulations.

Any breach of this Article may lead to suspension under Article 12. Abuse may be reported to the address given in Article 20.

Article 7 — Processing of Content and Personal Data

7.1. No retention of Content. Content is processed in memory only, for as long as needed to compute and deliver the response. It is never written to disk, to logs or to a database, and it is not kept once the response has been returned or the request interrupted, with the sole exception of the in-memory prefix cache described below. To speed up computation, the inference engine may keep in GPU memory an intermediate representation of the repeated parts of recent requests (prefix cache). This cache exists only in memory, is never written to disk, cannot be viewed by anyone and is gradually replaced by that of subsequent requests. JUST AI does not look at Content and keeps no copy of it once the request has completed. Anything You send on Your own initiative outside the Service, such as an example request attached to a support ticket, is not Content. It is handled as support correspondence and deleted no later than three (3) months after the ticket is closed.

7.2. No training. JUST AI does not use Content to train, fine-tune, align or evaluate any artificial intelligence model, or to build datasets. It does not share Content with any third party for such purposes.

7.3. Metadata. For each request, JUST AI records only the following Metadata: timestamp and request ID; model called; generation parameters (temperature, maximum tokens, etc.); input and output token counts; latency, time to first token and throughput; status code and, where applicable, error type; identifier of the Direct Customer or Platform and of the API Key used; connecting IP address (for a Platform: that of its servers). Metadata contains no Content. JUST AI does not record end-user identifiers that may accompany a request. Metadata is used for billing, usage metering, security, abuse detection, technical diagnostics and aggregated statistics. It is retained for thirty (30) days, including for security purposes. It is then deleted, or aggregated into content-free usage totals retained for ten (10) years to meet accounting obligations.

7.4. JUST AI's role under the GDPR. JUST AI processes Personal Data contained in Content solely to execute requests. With respect to a Direct Customer, it acts as a processor within the meaning of Article 28 GDPR, in accordance with the Data Processing Agreement, unless a separate signed agreement exists, in which case that agreement prevails. With respect to a Platform, its role is defined by the agreement with that Platform; absent any provision on this point, the Data Processing Agreement applies. Whatever that role, the commitments in Articles 7.1 and 7.2 apply. For Metadata and data relating to its customers, JUST AI acts as controller.

7.5. User responsibility. You are responsible for the lawfulness of the Inputs You send, including having a legal basis and informing data subjects. JUST AI does not hold the French Health Data Hosting (HDS) certification and does not enter into Business Associate Agreements under the US HIPAA rules. Do not use the Service for health data where regulations require a certified host or other specific safeguards.

7.6. Location and transfers. Content is processed in France, on the infrastructure described in Article 4.1. JUST AI returns each Output only to the endpoint that sent the request and does not transfer Content outside the European Union to any other recipient. Where that endpoint belongs to a Platform established or located outside the European Union, for example OpenRouter, Inc. in the United States, the return constitutes a transfer. JUST AI opens access to the Service through such a Platform only once one of the transfer mechanisms provided for in Chapter V of the GDPR covers that Platform: an adequacy decision applicable to it (for example the EU-US Data Privacy Framework, if the Platform is certified under it) or appropriate safeguards such as the standard contractual clauses adopted by the European Commission (Implementing Decision (EU) 2021/914). The routing of Content between You and the Platform is the Platform's responsibility.

7.7. Requests from authorities. JUST AI discloses Metadata to an authority only in response to a legally binding request and, where the law permits, informs the customer concerned. JUST AI cannot disclose Content it does not retain.

7.8. Privacy Policy. JUST AI's processing of Personal Data is described more broadly in its Privacy Policy, in particular Article 11 (https://justai.fr/en/confidentialite#api).

Article 8 — Security

8.1. JUST AI implements technical and organisational measures appropriate to the risks, including: encryption in transit (TLS); API Key authentication of requests, with API Keys stored hashed or encrypted; dedicated servers; restricted and logged administrative access, with strong authentication of administrators; regular application of security patches. Since no system is free of risk, JUST AI cannot guarantee absolute security.

8.2. In the event of a Personal Data breach affecting the Service, JUST AI notifies the Direct Customer or Platform concerned without undue delay and no later than forty-eight (48) hours after becoming aware of it. It provides them with the information available to it.

8.3. You are responsible for keeping Your API Keys confidential and for their use. Any compromise must be reported without delay to the address given in Article 20; JUST AI may then revoke the API Key concerned.

Article 9 — Ownership of Inputs and Outputs

9.1. You retain all Your rights in Your Inputs. You grant JUST AI only a non-exclusive right, limited to the duration of processing, to process them in order to execute Your requests, and You warrant that You hold the rights needed for this purpose.

9.2. JUST AI claims no rights in the Outputs and waives any right it may hold in them as against You, subject to the Model licences (Article 5). Outputs may not be protectable by copyright, and identical or similar Outputs may be generated for other users. JUST AI does not warrant that Outputs are free of third-party rights; it is Your responsibility to check this before any use.

9.3. The Service, the API, their documentation, the infrastructure and, where applicable, Models fine-tuned by JUST AI remain the property of JUST AI or its licensors. These Terms grant You no right in them other than the right to use the Service in accordance with these Terms.

Article 10 — Nature of AI outputs and AI Regulation

10.1. Outputs are produced by statistical models. They may be inaccurate, incomplete, outdated, biased or fabricated (non-existent facts or references), even when stated with confidence. They do not constitute professional advice, including legal, medical, financial or tax advice.

10.2. Any Output must be reviewed by a competent person before it is used for a decision likely to have significant effects on an individual. You shall comply with Article 22 GDPR on automated individual decision-making.

10.3. The Service applies no content filtering beyond the safeguards built into the Models by their Publishers. You are responsible for implementing safeguards suited to Your use, in particular if Your application is available to the public or to minors.

10.4. JUST AI and the User each comply, for their own part, with the obligations of the AI Regulation. When You integrate the Service into an AI system, You act as provider and/or deployer of that system and are responsible for the resulting obligations. These include the transparency obligations of Article 50 (informing people that they are interacting with an AI system, disclosing deep fakes and AI-generated text published to inform the public) and, where applicable, the obligations relating to high-risk systems. The Service has not been designed or assessed for high-risk uses. On request, JUST AI provides You with the information it holds on the Models, including the documentation published by their Publishers.

Article 11 — Availability, maintenance and usage limits

11.1. JUST AI uses reasonable efforts to ensure the availability and performance of the Service. Unless a service level has been agreed in writing, it does not guarantee any specific uptime, latency or throughput. Metrics published by a Platform (uptime, time to first token, throughput) are published under the Platform's responsibility.

11.2. The Service may be interrupted for maintenance. Except in emergencies, in particular security emergencies, JUST AI endeavours to schedule maintenance during low-traffic hours and to announce it in advance.

11.3. JUST AI may apply limits on rate, concurrent requests or volume, per API Key, per customer or per Model. When available capacity is reached, the Service may reject a request with HTTP status code 429 rather than queue it. You are responsible for handling such rejections (delayed retry or fallback to another provider).

11.4. JUST AI may add or withdraw Models. Except for compelling reasons (licence, security, legal obligation), the withdrawal of a Model is announced to the Direct Customers and Platforms concerned at least thirty (30) days in advance, including through the deprecation date published in the technical catalogue.

Article 12 — Suspension

12.1. JUST AI may suspend or restrict, without notice, all or part of the access to the Service (an API Key, a customer, a request stream or a Model) in the event of: (i) a breach of Article 5 or 6; (ii) a risk to the security or integrity of the Service, its users or third parties; (iii) an order from an authority or a legal obligation.

12.2. If a Direct Customer fails to pay, JUST AI may suspend access after a formal notice has remained without effect for fifteen (15) days.

12.3. Any suspension is proportionate to its cause and lifted as soon as the cause has ceased. Unless prohibited by law, JUST AI informs the Direct Customer or Platform concerned as soon as possible.

12.4. Where the Service is provided through a Platform, JUST AI cannot identify the end user. It therefore reports the abuse to the Platform, which alone can act on the account concerned. It suspends the Platform's entire traffic only as a last resort, in the event of a serious risk to the Service, its users or third parties.

Article 13 — Prices and invoicing

13.1. Direct Customers. Prices are those set out in the quotation, purchase order or current price list, exclusive of taxes. Unless otherwise agreed, usage is invoiced monthly in arrears, based on the tokens processed as measured by JUST AI. Invoices are payable within thirty (30) days of their issue date. Any late payment automatically incurs: penalties at the interest rate applied by the European Central Bank to its most recent refinancing operation, plus ten (10) percentage points; a fixed indemnity of forty (40) euros for recovery costs (Articles L. 441-10 and D. 441-5 of the French Commercial Code). Where the Direct Customer is a public purchaser, these provisions apply subject to public procurement rules. Any price change is notified at least thirty (30) days before it takes effect.

13.2. Access through a Platform. Where the Service is offered through a Platform, prices are those displayed by that Platform, which invoices and collects them from You under its own terms. JUST AI then invoices the Platform under the agreement between them.

Article 14 — Liability

14.1. JUST AI is liable for direct and foreseeable damage resulting from a proven breach of its obligations under these Terms.

14.2. JUST AI is not liable for: (i) indirect damage, such as loss of revenue, profit, customers or reputation; (ii) the content of Outputs or decisions made on the basis of them (Article 10), without prejudice to its obligation to run the Model, version and quantisation announced in the catalogue; (iii) the consequences of any use of the Service that does not comply with these Terms; (iv) the acts or omissions of a Platform or of any other third party that is not its subcontractor.

14.3. JUST AI's total liability, on all grounds combined, is limited to the greater of: (i) the amounts paid to JUST AI for the Service during the twelve (12) months preceding the event giving rise to liability; and (ii) one hundred (100) euros.

14.4. The limitations in this Article do not apply in the event of gross negligence or wilful misconduct, in the event of bodily injury, toward data subjects under Article 82 GDPR, or where the law prohibits limiting or excluding liability.

14.5. The Direct Customer or Platform shall indemnify JUST AI against any third-party claim, including by an authority, arising from the Inputs it sends or from any use of the Service in breach of Article 5 or 6 for which it is responsible. It shall bear the resulting awards, reasonable defence costs and settlement amounts, provided that JUST AI promptly informs it of the claim and allows it to take part in its defence.

Article 15 — Force majeure

Neither party is liable for a failure caused by a force majeure event within the meaning of Article 1218 of the French Civil Code. The affected party shall inform the other as soon as possible. If the impediment lasts more than thirty (30) days, either party may terminate the agreement by written notice.

Article 16 — Term and termination

16.1. Term. The agreement with a Direct Customer is for an indefinite term, unless the quotation or purchase order provides otherwise.

16.2. Termination. A Direct Customer may terminate at any time by written notice, subject to payment for usage incurred and to any term or volume commitments agreed in writing. JUST AI may terminate: (i) with thirty (30) days' notice, extended where necessary to reflect the length of the business relationship (Article L. 442-1, II of the French Commercial Code); (ii) without notice, in the event of a material breach not remedied within fifteen (15) days of a formal notice; (iii) without notice, in the event of a serious breach of Article 6.

16.3. Survival. Articles 7, 9, 13 (as regards amounts due), 14 and 17 and Annex 1 survive the end of the agreement.

Article 17 — Governing law and jurisdiction

17.1. These Terms are governed by French law.

17.2. In the event of a dispute, the parties shall seek an amicable settlement for thirty (30) days from its written notification, without prejudice to interim, protective or urgent measures.

17.3. Failing amicable settlement, any dispute relating to the formation, interpretation, performance or termination of these Terms shall be subject to the exclusive jurisdiction of the competent courts for the place where JUST AI's registered office is located, including for summary proceedings, third-party claims or where there are several defendants. This clause applies where all parties have contracted as merchants (commerçants) or, in international relations, under the conditions of Article 25 of Regulation (EU) No 1215/2012. In all other cases, including toward consumers, the statutory rules on jurisdiction apply.

Article 18 — Changes to the Terms

JUST AI may amend these Terms. The new version is published on this page with its effective date. Any material change is notified to Direct Customers by email, and to Platforms as provided in their agreement, at least thirty (30) days before it takes effect, unless a legal obligation or a security requirement calls for a shorter period. Where applicable, JUST AI updates the information it provides to Platforms, including the zero data retention flag, before any change takes effect. If You do not accept a change, You may stop using the Service and, if You are a Direct Customer, terminate without penalty before the change takes effect. Continued use after that date constitutes acceptance. No change may reduce the commitments of Article 7 with respect to Content and Metadata already transmitted.

Article 19 — Miscellaneous

19.1. Language. These Terms are drafted in French; the English translation is provided as a courtesy. In the event of any discrepancy, the French version prevails.

19.2. Partial invalidity. If any provision is held invalid or unenforceable, the remaining provisions remain in full force.

19.3. No waiver. Failure to enforce a provision does not constitute a waiver of the right to enforce it later.

19.4. Archiving. JUST AI archives each version of these Terms and provides it on request.

Annex 1 — Data Processing Agreement (Article 28 GDPR)

This agreement applies where JUST AI processes, as a processor, Personal Data contained in Content on behalf of a Direct Customer or, where applicable, a Platform (the “Customer”). A separate agreement signed between JUST AI and the Customer prevails over this agreement.

1. 1. Subject matter, duration, nature and purpose. JUST AI processes Content to execute the Customer's requests using the Models, that is, to compute and return Outputs. Processing lasts for the term of the agreement and, for each request, only for the time needed to execute it (Article 7.1). It serves no other purpose.
2. 2. Data and data subjects. Any Personal Data that the Customer or its users choose to include in Inputs, or that Outputs may contain, including, where applicable, special categories of data. Data subjects: the Customer's users and the individuals mentioned in Content.
3. 3. Instructions. JUST AI acts on the Customer's documented instructions, consisting of these Terms, this agreement and the parameters of each request. It immediately informs the Customer if, in its opinion, an instruction infringes the GDPR.
4. 4. Confidentiality. Persons authorised to administer the systems are bound by a duty of confidentiality.
5. 5. Security. JUST AI implements the measures described in Article 8 (Article 32 GDPR).
6. 6. Sub-processors. As of the date of these Terms, JUST AI uses no sub-processor with access to Content. The colocation operator named in Article 4.1 provides physical hosting of the servers only, with no logical access to them or to Content, and is not a sub-processor. JUST AI informs the Customer at least thirty (30) days in advance of any addition or replacement. The Customer may object on reasonable grounds and, failing a solution, terminate without penalty before the change. Any sub-processor is bound by contract to the same obligations.
7. 7. Assistance. To the extent possible, and given that Content is not retained, JUST AI assists the Customer in responding to data subject requests and in meeting its obligations under Articles 32 to 36 GDPR.
8. 8. Data breaches. JUST AI notifies any breach to the Customer as provided in Article 8.2.
9. 9. End of the agreement. Since Content is not retained, there is nothing to return or delete; JUST AI confirms this in writing on request.
10. 10. Audits. JUST AI makes available to the Customer the information needed to demonstrate compliance with this agreement. It allows an audit, on documents or on site, by an auditor bound by confidentiality and at the Customer's expense, no more than once a year except after a data breach, with thirty (30) days' notice.
11. 11. Transfers. Transfers are governed by Article 7.6.
12. 12. Metadata. JUST AI processes Metadata as controller (Article 7.4). Metadata is outside the scope of this agreement.
