+- `gpt-5.1` (codex-cli & openai): supports none, low, medium, high reasoning
+- `gpt-5.1-codex-max` (codex-cli & openai): supports none, low, medium, high, xhigh reasoning
+- `gpt-5.2` (codex-cli & openai): supports none, low, medium, high, xhigh reasoning  
+- `gpt-5.2-pro` (openai only): supports medium, high, xhigh reasoning

 ## Important Notes
 
 - **OAuth subscription required**: No API key needed for basic operation, but requires active ChatGPT subscription
-- **Limited model selection**: Only `gpt-5` and `gpt-5-codex` available via OAuth

 - **Pricing information**: Not available for OAuth models (shows as "Unknown" in cost calculations)
 - **No automatic dependency**: The `@openai/codex` package is not added to Task Master's dependencies - install it globally or enable `allowNpx`
 - **Codebase analysis**: Automatically enabled when using `codex-cli` provider
