Included review availability: Your plan includes up to 10 reviews per rolling hour; 9 remain after this review. 📝 WalkthroughWalkthroughThe PR adds configurable temperature overrides with model capability checks. The popup displays conditional controls and localized messages. Azure OpenAI, Claude, and OpenAI-compatible APIs use shared temperature handling. Tests cover configuration, model support, omitted parameters, and request precedence. ChangesTemperature override
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The change makes temperature overrides opt-in, but a later request-body merge can still reintroduce temperature through extraBody, bypassing compatibility safeguards and causing provider or model request failures. This bounded correctness issue should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

Greptile SummaryThe PR makes temperature overrides opt-in and centralizes model compatibility checks across supported API paths.
Confidence Score: 4/5The PR does not yet appear safe to merge because Azure requests can still send temperature to deployments backed by models that reject the parameter. Azure calls the shared temperature helper without a model identifier, and the helper treats an absent identifier as compatible, leaving the previously reported request-rejection path outstanding. Files Needing Attention: src/services/apis/azure-openai-api.mjs, src/services/apis/temperature-params.mjs, src/popup/sections/AdvancedPart.jsx
|
| Filename | Overview |
|---|---|
| src/services/apis/temperature-params.mjs | Centralizes opt-in and model-family checks for deciding whether request bodies include temperature. |
| src/popup/sections/AdvancedPart.jsx | Adds the override checkbox and aligns custom-model compatibility messaging with request model resolution. |
| src/services/apis/openai-compatible-core.mjs | Applies the shared temperature policy and prevents extra request fields from bypassing it. |
| src/services/apis/azure-openai-api.mjs | Applies opt-in temperature handling, but still lacks the model identity needed to block incompatible Azure deployments. |
| src/services/apis/claude-api.mjs | Replaces local Anthropic exclusions with the shared temperature compatibility policy. |

No code change is needed here. getModelValue(config) resolves a custom API mode through apiModeToModelName() and modelNameToValue(), which removes the customApiModelKeys- prefix and returns the actual customName.
The request path also uses session.apiMode.customName, so the UI and request evaluate the same model ID.

Problem
ChatGPTBox currently sends
temperatureby default for OpenAI-compatible, Azure OpenAI, and supported Anthropic requests because the global default is1. That prevents providers and models from using their own defaults, and newer models may reject custom sampling parameters entirely.Existing installations may already have a stored numeric
temperature, including values that originated from older defaults. Treating the presence of that value as explicit user intent would keep the old behavior for many users.Changes

temperaturevalues are retained.References
Validation
The final single-commit head passed the repository's complete pull-request checks:
npm run test:coveragenpm run lintnpm run buildnpm run build:safariFocused tests cover default omission, explicit override, incompatible-model handling, legacy stored-temperature behavior, Azure deployment aliases, provider-qualified suffixes, Gemini version boundaries, and both chat and completion request-body precedence.
