Summary

  • Add Google Gemini 3.5 Flash-Lite (gemini-3.5-flash-lite).
  • Add Google Gemini 3.6 Flash (gemini-3.6-flash).
  • Add Google Gemini 3.7 Flash (gemini-3.7-flash).
  • Update the default-enabled Google Flash model from Gemini 3.5 Flash to Gemini 3.7 Flash.
  • Keep Gemini 3.1 Pro enabled by default.
  • Keep Gemini 3.5 Flash, Gemini 3.5 Flash-Lite, and Gemini 3.6 Flash available for manual selection.

Default behavior

For fresh installs and profiles that still use the live default API-mode list, the Google defaults change from Gemini 3.1 Pro + Gemini 3.5 Flash to Gemini 3.1 Pro + Gemini 3.7 Flash.

For materialized profiles with an existing default baseline, the existing reconciliation behavior is non-destructive: the new Gemini 3.7 Flash default can be appended, while an already materialized Gemini 3.5 Flash entry is not automatically removed or disabled. Older snapshots without a valid baseline continue to follow the existing conservative baseline-migration behavior. This preserves user choices instead of forcing a migration.

References

Validation

  • Rebuilt on the latest master.
  • One file changed: src/config/index.mjs.
  • defaultApiModeIds only replaces googleGemini3_5Flash with googleGemini3_7Flash; googleGemini3_1Pro remains unchanged.
  • No provider-routing or request-parameter behavior is changed by this PR.
  • Gemini temperature handling is covered by the already-merged opt-in temperature policy.

Summary by CodeRabbit

  • New Features

    • Added support for three new Google Gemini models: Gemini 3.5 Flash-Lite, Gemini 3.6 Flash, and Gemini 3.7 Flash.
    • Added model information for the new options.
  • Updates

    • Updated the default model selection to include Gemini 3.7 Flash and remove two older models.

📝 Walkthrough

Walkthrough

The configuration adds three Google Gemini model keys and metadata entries. It updates the default API mode list to use Gemini 3.7 Flash instead of Gemini 3.1 Pro and Gemini 3.5 Flash.

Changes

Gemini model registration

Layer / File(s) Summary
Add Gemini model configuration
src/config/index.mjs
The configuration adds Gemini 3.5 Flash-Lite, 3.6 Flash, and 3.7 Flash keys and metadata. The default API mode list now includes Gemini 3.7 Flash and removes two previous models.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟡 Moderate · up to 59265

This PR adds newer Gemini models and changes the default Flash model to Gemini 3.7 Flash while preserving existing customized selections, but the branch still contains invalid workflow YAML that prevents GitHub Actions from running; the workflow issue should be fixed or explicitly accepted before merge.

High-Level Assessment

The following are alternative approaches to this PR:

1. Generate model registry from provider metadata
  • ➕ Reduces manual updates when Google releases new models
  • ➕ Can validate model availability/region support automatically
  • ➖ Adds runtime/network dependency or build-time tooling complexity
  • ➖ Provider metadata formats can change and require maintenance
2. Move model definitions to a dedicated JSON/YAML registry
  • ➕ Cleaner separation of data vs code; easier review diffs
  • ➕ Enables reuse across packages and simpler testing/validation
  • ➖ Requires refactor of current config import/typing patterns
  • ➖ Still manual unless combined with generation tooling

Recommendation: The current additive config approach is appropriate and low-risk for a small, infrequent update. If Gemini model churn becomes frequent, consider build-time generation or a separate data registry to reduce repetitive manual PRs and improve validation (e.g., uniqueness checks, provider availability assertions).

Register new Gemini models and add them to defaults

• Adds three new Google Gemini model definitions (3.5 Flash-Lite, 3.6 Flash, 3.7 Flash) to the Models registry. Extends the Google API model key allowlist and includes the new entries in the default API mode IDs list without reordering existing models.

Greptile Summary

Adds Gemini 3.5 Flash-Lite, 3.6 Flash, and 3.7 Flash to the Google API model configuration.

  • Registers each model’s provider identifier and display description.
  • Includes all three models in the default API-mode list without changing existing entries.

Confidence Score: 5/5

The PR appears safe to merge with no actionable defects identified.

The new model keys consistently match their model definitions and default API-mode entries, and existing prefix- and group-based routing resolves them through the Google provider.

Important Files Changed

Filename Overview
src/config/index.mjs Adds three internally consistent Gemini model definitions, Google provider-group keys, and default API-mode entries.

Code Review by Qodo

🐞 Bugs (0) 📘 Rule violations (0) 📜 Skill insights (0)

Grey Divider


Remediation recommended

1. New Gemini desc not localized ✗ Dismissed 📘 Rule violation ⚙ Maintainability
Description
The PR adds new user-facing model labels via desc, but no corresponding localization entries were
added, so translations cannot be provided for non-English locales.
Code

src/config/index.mjs[R681-684]

+  googleGemini3_5FlashLite: {
+    value: 'gemini-3.5-flash-lite',
+    desc: 'Google (Gemini 3.5 Flash-Lite)',
+  },
Evidence
The change introduces new desc strings for Gemini models in Models, and the UI path resolves
model labels by passing Models[modelName].desc into t(...); without adding these strings as
localization keys, they cannot be translated per the localization requirement.

Rule 2262059: Add new English localization keys before other locales
src/config/index.mjs[681-692]
src/utils/model-name-convert.mjs[26-33]

Agent prompt
The issue below was found during a code review. Follow the provided context and guidance below and implement a solution

## Issue description
New model labels were added as `desc` strings but are not present in the localization resources, preventing proper translation coverage.

## Issue Context
`modelNameToDesc()` calls `t(Models[modelName].desc)`, so the `desc` values act as i18n lookup keys.

## Fix Focus Areas
- src/config/index.mjs[681-692]
- src/_locales/en/main.json[1-200]
- src/_locales/*/main.json[1-200]
- src/utils/model-name-convert.mjs[26-33]

This behavior is already covered by the generic default-reconciliation tests. This PR only changes the default IDs, so I don't think a model-specific regression test is necessary.
