Gpt4free should be able utilize free web interfaces for you. There’s a load of already known free models, but they are of lower quality. To utilize big models from free web sites, a little setup is needed where you record a login on Deepseeks page, and it creates an automation file and reuse that login. It then creates a local endpoint and serves the web page as if it were a std api. I haven’t actually tried it myself, so something like that. Check it out.

IIRC, Openrouter has free Deepseek models. Best I can offer unfortunately.

maybe try to use the newer qwen stuff via their api. they give free tokens of certain amount on signup
