* 📤 feat: Model-Aware Max Output Tokens for Google/Gemini Resolves #13384. Current Gemini text models (2.5 and 3+, including Gemini 3.5 Flash) support 64K output tokens, but LibreChat defaulted every Google model to the legacy 8K value — most visibly in the Agents model-parameter panel. - Add model-aware `reset`/`set` to `googleSettings.maxOutputTokens`, mirroring the Anthropic pattern: Gemini 2.5/3+ -> 65536, legacy (2.0 and earlier) and Gemma -> 8192. - Resolve the default server-side in `getGoogleConfig` and in the Agents, preset, and standard Google settings panels via a shared `applyModelAwareDefaults` helper. - Make `compactGoogleSchema` and `generateGoogleSchema` model-aware so explicit user values are preserved and not overwritten. * 🛡️ fix: Cap Google max output at Vertex-safe limits Addresses Codex review (P1) on #13390. Vertex AI caps current Gemini text models at 65,535 output tokens (vs 65,536 on AI Studio) and image models at 32,768, so an unconditional 65,536 default could make otherwise-default Vertex requests fail validation. - Lower the modern text default/ceiling to 65535 (valid on both Vertex and AI Studio). - Resolve Gemini image models (e.g. gemini-2.5-flash-image) to 32768. - Add reset/set + getGoogleConfig tests for image models and the Vertex default path. * 🧮 fix: Respect configured Google defaults and legacy image caps Addresses Codex review round 2 on #13390 (one P2, two P3). - P2 (llm.ts): apply the model-aware maxOutputTokens default as the final fallback instead of pre-filling it, so an explicit value, `defaultParams`, and `addParams` all take precedence and `dropParams` is honored. Empty-string values stay stripped (preserves prior Gemini empty-payload handling). - P3 (panels): pass the resolved params endpoint (`overriddenEndpointKey`) to `applyModelAwareDefaults`, so custom endpoints with `defaultParamsEndpoint: 'google'` also surface the model-aware default. - P3 (schemas): nest the image-model check inside the 2.5+/3+ version check, so legacy image IDs (e.g. gemini-2.0-flash-preview-image-generation) keep the 8K cap instead of being treated as 32K models. - Add tests for defaultParams precedence, dropParams, legacy image models, and the Vertex default path. * 🧭 fix: Base Google defaults on final model and configured overrides Addresses Codex review round 3 on #13390 (two P2). - llm.ts: resolve the model-aware maxOutputTokens default from the final `llmConfig.model` (after defaultParams/addParams) instead of the model captured from modelOptions, so a model forced via addParams/paramDefinitions on a Google-compatible custom endpoint gets its correct limit. - Panels: apply model-aware defaults to the built-in settings first, then overlay `customParams.paramDefinitions`, so an admin-configured maxOutputTokens default wins in the UI (consistent with backend precedence). - Add parameterSettings.spec for applyModelAwareDefaults (incl. override precedence) and a getGoogleConfig final-model test. |
