Tips to not hit the rate limit

• Use a free model from free provider like Gemini/Mistral/Openrouter for the weak model
• Rarely use architect mode
• Do not enable automatic yes in aider config
• Claude 3.7 thinking mode uses more tokens. Use it sparingly

Roadmap

• Manual approval for every request
• Rate limiting (only allow request every X seconds)
• Token counting
