# Corti Models

> Updates and improvements to Corti Models — text generation, embeddings, and the model platform

Detailed documentation about Corti Models is available [here](/models/welcome).

<Update label="2026-08-20" tags={["Models", "Release"]}>
  #### Corti Models General Availability <Badge className="accent-badge" shape="rounded">General Availability</Badge>

  Corti Models is now generally available. The `corti-s1` family — `corti-s1`, `corti-s1-instant`, `corti-s1-mini`, and `corti-s1-mini-instant` — is served through an OpenAI-compatible API on Corti-managed sovereign infrastructure with zero data retention.

  * **Four text-generation variants** combining model tier (frontier, efficient) and reasoning mode (with reasoning, instant) — see [Models](/models/models).
  * **`corti-s1`** (frontier tier) is powered by GLM 5.2; **`corti-s1-mini`** (efficient tier) is powered by Qwen 3.6. Corti continuously evaluates and may replace the underlying foundation model behind each stable ID as the frontier moves.
  * **Embeddings** via `corti-s1-embedding` for semantic search, clustering, and RAG pipelines.
  * **Sovereign deployment**: EU inference runs entirely on Corti-managed European infrastructure; US projects are served by Azure-hosted OpenAI models under the same model IDs. See [Regions](/models/regions).
  * **OpenAI-compatible API**: swap your base URL and API key — existing OpenAI SDK code works unchanged. See [Quickstart](/models/quickstart).
  * **Coding agent support**: point OpenCode, Pi, Crush, or ForgeCode at Corti Models with the Corti CLI. See [Use Corti Models in your coding agent](/models/ai-coding-agent).

  Corti continuously upgrades the underlying foundation model behind each stable model ID, so you always get the best available model without changing your code. See [How Corti models work](/models/how-models-work).
