Best Free / Generous Free Models on OpenRouter for Coding (March 2026)?

[ornate furnace]

Hey everyone! I'm looking for recommendations on completely free or generously free models available on OpenRouter that are actually good for coding tasks (code generation, debugging, refactoring, etc.) — as alternatives to the paid ones like Claude Sonnet or GPT-4o.
What are you guys currently using? Any hidden gems worth trying?

spend 5 years worth of Claude 20x max cost to run this piece of shit that literally can't do anything and will eventually rm rf your whole PC!

completely free, local, and private!

why? GPT 4o is great for coding!

I hope you are joking 😂. Also he said he wanted free, and GPT 4o isn't free.
