claude-opus-4.7 via GitHub Copilot fails with thinking.type.enabled not supported #23500
Description
Bug Report
Model: github-copilot/claude-opus-4.7
Description
When using claude-opus-4.7 via the GitHub Copilot provider with a reasoning variant (high or max), the request fails with:
"thinking.type.enabled" is not supported for this model. Use "thinking.type.adaptive" and "output_config.effort" to control thinking behavior.
Root Cause
In packages/opencode/src/provider/transform.ts, the isAnthropicAdaptive check determines whether a model should use thinking.type=adaptive (new API) vs thinking.type=enabled (legacy API):
const isAnthropicAdaptive = ["opus-4-6", "opus-4.6", "sonnet-4-6", "sonnet-4.6"].some((v) =>
model.api.id.includes(v),
)claude-opus-4.7 is missing from this list, so it falls through to the legacy path which GitHub Copilot explicitly rejects.
Expected Behavior
claude-opus-4.7 should use thinking.type=adaptive + output_config.effort, same as claude-opus-4.6.
