Model identifier
claude-sonnet-5 Model overview
Claude Sonnet 5 balances response speed and reasoning for everyday coding and assistant workloads. The official model supports text and image input with text output.
Tasks to evaluate
- Build interactive coding assistance and iterative explanations.
- Analyze supplied text and visual context to draft useful responses.
Integration notes
The official API changed thinking and sampling behavior. Start with minimal request fields instead of carrying over non-default sampling values.
Based on provider documentation, not a GetAPI execution test. Supported request fields and limits depend on the selected endpoint.

Before your first request
- Confirm the exact model identifier and supported endpoint.
- Create a server-side API key with the required permissions and quota.
- Match the model endpoint type to a compatible request protocol before sending traffic.
A model listed by the gateway is not automatically compatible with Codex. Use its declared endpoint as a starting point, then confirm request fields and billing before testing.
