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

   • Copilot: output_config.effort "max" is not supported by model claude-opus-4.6 #22788: Same root cause — GitHub Copilot silently changed supported API parameters for Claude Opus models. That issue reports output_config.effort "max" not being supported, while this one reports thinking.type.enabled not being supported. Both appear to be part of the same Copilot API change affecting thinking/effort configuration for Claude Opus.

   Same error reproduces on the OpenCode Zen provider as well, so this is not specific to the GitHub Copilot provider — likely a shared upstream issue with how OpenCode sends the thinking config to Claude Opus 4.7.

   Environment

   • OpenCode version: 1.4.6
   • Provider: OpenCode Zen (subscription)
   • Model: Claude Opus 4.7
   • OS: macOS 26.4

   Steps to reproduce

   1. Select Claude Opus 4.7 via the OpenCode Zen provider
   2. Toggle the thinking/reasoning switch on in the TUI
   3. Send any message

   Error

   "thinking.type.enabled" is not supported for this model. Use "thinking.type.adaptive" and "output_config.effort" to control thinking behavior.
   

   The error message from the upstream API suggests OpenCode should migrate from thinking.type.enabled to thinking.type.adaptive + output_config.effort for Opus 4.7.

   For github copilot specifically, I think we may be mistakenly showing models u may not have access to, for example I can see it in my model list but the api says it is "disabled"

   If you can access the model in other copilot products it should work tho.
