GPT-OSS 120B (OpenAI)

Open weights & AI Act facts

Factual characteristics of this model's weights — stated, not certified. Under the EU AI Act, whether a deployment is compliant depends on the model, your role and your use case.

Open weights

Weights public and freely executable

AI Act class

GPAI — general-purpose AI

Systemic risk

Below the systemic-risk threshold

Data retention

None at Frontière AI; Scaleway states prompts are not stored, except requests causing errors or abuse (kept up to 2 weeks)

Frontière Verified

Our 6-criteria checklist for this model. Each criterion is assessed independently — a checkmark means we ran, recorded and passed the check; an empty circle means not confirmed yet.

Compliance evidence

Provider facts for this model's serving path, as documented by Frontière AI; the retention row quotes each provider's own documentation where it exists. Dates reflect the most recent documented audit of each fact.

Provider / operator

Scaleway Generative APIs

Country

France

Ownership / control

EU-controlled — no non-EU capital control

Jurisdiction

EU (observed serving region)

Deployment

Managed cloud inference

Data retention

None at Frontière AI; Scaleway states prompts are not stored, except requests causing errors or abuse (kept up to 2 weeks)

Frontière AI retains neither prompts nor completions from API calls; processing is structured to fit a short DPA (Art. 28 GDPR). DPA and subprocessor documentation available on request.

What its label means

This model is run by a French provider (OVHcloud or Scaleway), in data centres in France. It is not a US company, so the CLOUD Act does not reach it the way it reaches a US provider, and under GDPR a foreign court order is only enforceable in the EU through an international agreement (Article 48). That is the SecNumCloud principle — who controls the operator matters more than where the servers sit — applied as a label, not a qualification: this service is not SecNumCloud-qualified. Our gateway runs in Vercel's Paris region (a US company): your prompts pass through it without being stored.

Calling it

The API is OpenAI-compatible. Change base_url and the key, then use this model id:

client = OpenAI(
    base_url="https://getfrontiereai.eu/api/v1",
    api_key=os.environ["FRONTIERE_KEY"],
)

reply = client.chat.completions.create(
    model="gpt-oss-120b",
    messages=[{"role": "user", "content": "Bonjour"}],
)

One key covers the whole catalog — you switch models by changing a single string.

Pricing

The price you see is the price debited from your prepaid balance, margin and VAT included — not an infrastructure cost. No subscription: top up from €10; calls are refused once the balance reaches zero, and a call already running can take it slightly below — deducted from your next top-up.

What will it cost you?

Pick a workload or type your own token counts: the estimate uses the prices above, margin and VAT included.
