# Deprecations

> We’re excited to keep our platform at the cutting edge with robust open-source model upgrades.

Below you’ll find our clear deprecation framework and step-by-step guidance to transition smoothly between model versions – we’ve designed this resource to make your migration effortless and interruption-free.

**Key enhancements:**

* **Proactive updates:** We continuously integrate state-of-the-art models while maintaining backward compatibility where possible

* **Transparent timelines:** Deprecated models receive advance warnings and parallel support during phase-out periods

* **Guided workflows:** Interactive documentation and automated version-check tools simplify transitions

## API keys removal

<Warning>
  **API keys are no longer supported**

  API keys are no longer an accepted method of authentication as of November 1, 2025. Service tokens now provide the authentication surface for all automation and integrations, offering finer-grained scoping and rotation controls. Migrate any remaining API key usage to service tokens to restore access.
