I'm using Cline and currently using Gemini 2.5 Pro Exp for plan mode, and gemini 2.0 flash Exp for act mode. Doesn't cost anything as long as you have $10 credit in OpenRouter, add your own Gemini API key in OpenRouter Integration page, and you use plan mode slowly (1 request per minute). Close to Claude 3.7? Can't tell, but it works well for me to develop small WordPress plugins. I would recommend using DeepSeek R1 and DeepSeek V3, but it keeps getting errors in both Roocode and Cline. Answer from awipra on reddit.com

R1 or Gemini flash are the closest. Neither of them get close to 3.5 or 3.7 or gemini 2.5 pro tbh If you’re using roo, use the google api to get free gemini 2.5, its limited but better than most openrouter free options

Free‑tier usage of popular models can be subject to rate limiting by the provider, especially during peak times. Failed attempts still count toward your daily quota. Can I separate environments (dev/staging/production)? Yes. Create separate API keys per environment with their own caps, alerts, and activity logs.
