# Model Name Updates Required - June 2025 ## Current Issues Found ### OpenAI Models **Current in code:** - `gpt-4o`, `gpt-4o-mini`, `gpt-4-turbo`, `gpt-4`, `gpt-3.5-turbo` **Issues:** 1. Missing GPT-4.1 family (current flagship models) 2. GPT-4.5 is being deprecated (removed from API July 14, 2025) 3. Missing latest reasoning models (o3, o4-mini) 4. Validator function has hardcoded old model list **Should be updated to (June 2025):** - `gpt-4.1` (current flagship, 1M context, superior performance) - `gpt-4.1-mini` (fast & affordable, 1/5th price of GPT-4.1) - `gpt-4.1-nano` (OpenAI's first nano model) - `gpt-4o` (keep current - still available) - `gpt-4o-mini` (keep current - still available) - `o3` (latest reasoning model) - `o3-mini` (reasoning model) - `o4-mini` (newer reasoning model) - Remove `gpt-4`, `gpt-3.5-turbo` (likely deprecated) ### Gemini Models **Current in code:** - `gemini-pro`, `gemini-1.5-pro`, `gemini-1.5-flash` **Issues:** 1. `gemini-pro` is from retired Gemini 1.0 family 2. Missing Gemini 2.5 family (latest available June 2025) 3. Gemini 1.5 models unavailable for new projects since April 2025 **Should be updated to (June 2025):** - `gemini-2.5-pro` (most advanced reasoning model with thinking capabilities) - `gemini-2.5-flash` (best price/performance, thinking capabilities) - `gemini-2.5-pro-deep-think` (experimental enhanced reasoning mode) - `gemini-2.5-flash-preview-05-20` (specific API version) - Remove `gemini-pro` (retired) - Remove `gemini-1.5-pro`, `gemini-1.5-flash` (unavailable for new projects) ## Files Requiring Updates 1. **src/constants.js** - Lines 9, 36-37 2. **src/validators.js** - Lines 44-46 (hardcoded model list) 3. **README.md** - Multiple references to model names 4. **tests/*.js** - Test files with model references ## Recommended Defaults (June 2025) ### New Defaults - **OpenAI default**: `gpt-4o-mini` → `gpt-4.1-mini` (faster, 1/5th price, similar performance to GPT-4.1) - **Gemini default**: `gemini-pro` → `gemini-2.5-flash` (best price/performance, thinking capabilities) ## Critical Updates for June 2025 ### OpenAI Changes - **GPT-4.1** is now the flagship model family (released recently) - **GPT-4.5** being removed from API on July 14, 2025 - New reasoning models: o3, o3-mini, o4-mini available - GPT-4.1 offers superior performance to GPT-4.5 at much lower cost ### Gemini Changes - **Gemini 2.5** is the current flagship with "thinking capabilities" - **Gemini 1.5** models unavailable for new projects since April 2025 - **Gemini 2.5 Flash** improved 20-30% efficiency over previous versions - **Deep Think** mode available for complex reasoning tasks ## Priority Actions 1. **High Priority**: Update Gemini default from retired `gemini-pro` to `gemini-2.0-flash` 2. **High Priority**: Add GPT-4.1 family models 3. **Medium Priority**: Update documentation 4. **Medium Priority**: Update test files
