Z.ai GLM models don't support thinking/reasoning parameters.
Ensure these are omitted entirely to prevent empty responses.
Fixes#980
Community-reported-by: @iserifith
Add claude-opus-4-6 as the first anthropic provider entry before
claude-opus-4-5 across all agent and category fallback chains.
Also add high variant mapping for think-mode switcher.
Add thinking mode support for Z.AI's GLM-4.7 model via the zai-coding-plan provider.
Changes:
- Add zai-coding-plan to THINKING_CONFIGS with extra_body.thinking config
- Add glm pattern to THINKING_CAPABLE_MODELS
- Add comprehensive tests for GLM thinking mode
GLM-4.7 uses OpenAI-compatible API with extra_body wrapper for thinking:
- thinking.type: 'enabled' or 'disabled'
- thinking.clear_thinking: false (Preserved Thinking mode)
Closes#1030
When using custom providers with model ID prefixes (e.g., vertex_ai/claude-sonnet-4-5),
the think mode switcher was stripping the prefix when mapping to high variants,
causing routing failures in custom LLM proxies.
Changes:
- Add extractModelPrefix() to parse and preserve prefixes like vertex_ai/, openai/, etc.
- Update getHighVariant() to preserve prefix when mapping to -high variants
- Update isAlreadyHighVariant() to check base model name (without prefix)
- Update getThinkingConfig() to check capability using base model name
- Add comprehensive tests for custom provider prefix scenarios
This fix ensures backward compatibility while supporting custom providers
that use prefixed model IDs for routing.
Fixes issue where think mode would break custom providers with prefixed models
by stripping the routing prefix during model variant switching.
* fix(think-mode): support GitHub Copilot proxy provider
### Summary
- Adds `github-copilot` support to think-mode by resolving the underlying provider from the model name (Claude → Anthropic, Gemini → Google, GPT/o* → OpenAI).
- Normalizes model IDs to handle dotted versions defensively (e.g. `claude-opus-4.5` → `claude-opus-4-5`, `gpt-5.2` → `gpt-5-2`) so high-variant upgrades and capability checks work reliably.
- Expands high-variant mappings to cover Gemini preview/flash variants and aligns GPT-5.1/5.2 mappings with normalized IDs.
- Adds OpenAI “thinking mode” config (`reasoning_effort: "high"`) alongside existing provider configs.
### Tests
- Adds unit coverage for the switcher (`switcher.test.ts`) and integration coverage for the hook (`index.test.ts`), including:
- GitHub Copilot model routing + thinking config injection
- Dots vs hyphens normalization
- Already-`-high` variants not being re-upgraded
- Unknown models/providers handled gracefully
* fix: support multiple digits in model minor
- Actually inject THINKING_CONFIGS into message (was defined but unused)
- Add maxTokens: 128000 for Anthropic (required for extended thinking)
- Add maxTokens: 64000 for Amazon Bedrock
- Track thinkingConfigInjected state
