Apertus v1.5 70B (Swiss open model)

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

Not assessed by us — training compute not published, or too close to the 10²⁵ FLOP threshold to call

Data retention

None at Frontière AI; Infomaniak states queries are neither stored nor logged, nor used for training

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

Infomaniak AI Tools

Country

Switzerland

Ownership / control

Independent Swiss company (Infomaniak, Geneva) — no US parent, outside the direct reach of the CLOUD Act

Jurisdiction

Switzerland — outside the EU, covered by an EU adequacy decision (Swiss FADP + GDPR)

Deployment

Managed cloud inference (Infomaniak's own Swiss datacenters)

Data retention

None at Frontière AI; Infomaniak states queries are neither stored nor logged, nor used for training

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 Infomaniak, an independent Swiss company with no US parent, in its own datacenters in Switzerland. Switzerland is not in the EU, but the European Commission recognises its data protection law as adequate, so personal data can flow there under the GDPR without extra safeguards. As a Swiss company, Infomaniak is not reached by the CLOUD Act the way a US provider is. Infomaniak states that queries are neither stored nor logged. Our gateway runs in Vercel's Paris region (a US company): your prompts transit there 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="apertus-v1.5-70b",

)

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.
