Phoeniqs AI Model Service
The Phoeniqs AI Model Service gives you access to a curated suite of open-source Large Language Models (LLMs), hosted entirely on Swiss sovereign infrastructure via an OpenAI-compatible API.
Models are served using vLLM for optimized inference, with support for streamed responses and token-per-minute throughput pricing.
Free to try
An Evaluation Plan is available to test all models at no cost — no credit card, no commitment.

Model naming
Model identifiers on the Phoeniqs Model Service follow semantic versioning at the major version only. The name you use in API calls stays stable across minor and patch releases, for example inference-glm5 (GLM 5), not GLM 5.1 or GLM 5.2. See the Active Models table for the current identifier for each model.
This means you do not need to actively update the model name in your applications or agents at each minor or patch release, your existing API calls keep working against the same identifier while Phoeniqs upgrades the model behind it.
When we ship a minor or patch update behind an existing model ID, we do not send a separate email announcement; the change is recorded in the Changelog. We do notify customers by email when:
- a new major version is promoted to the active catalog, or
- a previously reachable model ID is permanently removed, even if the underlying release was only a minor or patch change.
For those cases, you may need to update your integration, for example, when migrating to a new major version or before a decommissioned model ID stops responding.
