This issue might be a duplicate of existing issues. Please check:

• BUG: Using Opus 4.7 via Github Copilot provider #22857: Reports the exact same error message ("thinking.type.enabled" is not supported for this model) when using Opus 4.7, also on version 1.4.6 (via GitHub Copilot provider)

I'm seeing the same issue when I attempt to switch Opus 4.7 to a different thinking mode (high, max)

Operating system: Windows 11 Business
Opencode Version: 1.1.51

Also affects the Opus 4.7 max variant (not just the base Opus 4.7).

OpenCode version: 1.4.6

Full error:

undefined: The model returned the following errors: {"type":"error","request_id":"req_xnfm35y47awzoayvyrtkuq4ab37yotm5vvlafccxdtwofjrfqm7a","error":{"type":"invalid_request_error","message":"\"thinking.type.enabled\" is not supported for this model.

Upstream documentation: https://platform.claude.com/docs/en/build-with-claude/adaptive-thinking

Claude Opus 4.7 (claude-opus-4-7), adaptive thinking is the only supported thinking mode. Thinking is off unless you explicitly set thinking: {type: "adaptive"} in your request; manual thinking: {type: "enabled"} is rejected with a 400 error.

and

thinking.type: "enabled" and budget_tokens are deprecated on Opus 4.6 and Sonnet 4.6 and will be removed in a future model release. Use thinking.type: "adaptive" with the effort parameter instead. Existing budget_tokens configurations are still functional but no longer recommended; plan to migrate.

The fix is already merged to dev but not yet in a tagged release (v1.4.6 is behind by 100+ commits):

• 378c05f feat: Add support for claude opus 4.7 xhigh adaptive reasoning effort (feat: Add support for claude opus 4.7 xhigh adaptive reasoning effort #22833)
• 47e0e23 tweak: set display 'summarized' by default for opus 4.7 through messages api (tweak: set display 'summarized' by default for opus 4.7 thorugh messages api #22873)

These switch Opus 4.7 (and Opus 4.6 / Sonnet 4.6) to thinking: { type: "adaptive" } with the effort parameter, per https://platform.claude.com/docs/en/build-with-claude/adaptive-thinking — matching what @copiousfreetime linked above.

Users hitting this on v1.4.6 should be unblocked once the next release is cut from dev.
