Summary

This PR adds AI Stupid Level integration to open-lovable, providing 6 intelligent auto-routing models that automatically select the best AI model for each task.

Changes Made

1. app/api/generate-ai-code-stream/route.ts

• Added AI Stupid Level client using @ai-sdk/openai with custom baseURL (https://aistupidlevel.info/v1)
• Added provider detection for aistupidlevel/ prefix models
• Updated model routing logic to support AI Stupid Level models

2. config/app.config.ts

• Added 6 AI Stupid Level models to the availableModels array:
  • aistupidlevel/auto - Best overall performance
  • aistupidlevel/auto-coding - Optimized for coding tasks (default)
  • aistupidlevel/auto-reasoning - Optimized for reasoning tasks
  • aistupidlevel/auto-creative - Optimized for creative tasks
  • aistupidlevel/auto-fastest - Optimized for speed
  • aistupidlevel/auto-cheapest - Optimized for cost efficiency

Benefits

• Intelligent Routing: Automatically selects the best model based on task requirements
• Multi-Provider Support: Leverages multiple AI providers (Anthropic, OpenAI, Google, etc.)
• Cost Optimization: Choose between performance, speed, or cost
• Easy Integration: Works seamlessly with existing codebase

Testing

The integration follows the same pattern as other providers (Anthropic, OpenAI, Google) and uses the standard @ai-sdk/openai package with a custom base URL.
