From b72c0f68f350166215cdb69cc69ac2c32588030f Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 13 Jan 2026 16:04:07 +0000 Subject: [PATCH 1/4] feat: refactor model selection logic for clarity and correctness Refactors the `getModel` function in `lib/utils/index.ts` to use a configuration map for model initializers. This change improves the clarity and maintainability of the code, and it fixes a bug where the user's selected model was not being used correctly. The new implementation prioritizes the user's selected model and includes robust error handling with a graceful fallback to a default provider chain if the selected model fails to initialize (e.g., due to a missing API key). This ensures the application remains functional while respecting the user's choice whenever possible. Additionally, this change adds support for the "QCX-Terra" model, which uses the Amazon Bedrock provider, and includes the necessary environment variables in the `.env.local.example` file. --- .env.local.example | 6 ++ lib/utils/index.ts | 136 ++++++++++++++++++--------------------------- 2 files changed, 60 insertions(+), 82 deletions(-) diff --git a/.env.local.example b/.env.local.example index 1934b0c0..436fe0e0 100644 --- a/.env.local.example +++ b/.env.local.example @@ -20,6 +20,12 @@ NEXT_PUBLIC_COMPOSIO_USER_ID=user@example.com # Gemini 3 Pro (Google Generative AI) GEMINI_3_PRO_API_KEY=your_gemini_3_pro_api_key_here +# AWS Bedrock Credentials +AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY_ID_HERE +AWS_SECRET_ACCESS_KEY=YOUR_AWS_SECRET_ACCESS_KEY_HERE +AWS_REGION=YOUR_AWS_REGION_HERE +BEDROCK_MODEL_ID=YOUR_BEDROCK_MODEL_ID_HERE + # Supabase Credentials NEXT_PUBLIC_SUPABASE_URL=YOUR_SUPABASE_URL_HERE NEXT_PUBLIC_SUPABASE_ANON_KEY=YOUR_SUPABASE_ANON_KEY_HERE diff --git a/lib/utils/index.ts b/lib/utils/index.ts index 64e8a305..218c27a6 100644 --- a/lib/utils/index.ts +++ b/lib/utils/index.ts @@ -19,103 +19,75 @@ export function generateUUID(): string { export async function getModel(requireVision: boolean = false) { const selectedModel = await getSelectedModel();

The identifier was previously changed to an incorrect value, which caused the model initialization to fail and the system to fall back to the default provider.
