you can self host if u got some hardware
or in opencode there's Deepseek V4 Flash that's free, so far it built me that thing:





Qwen 3.6 locally for like full codebase audits and things like that since it can do 1M context window
then the Deepseek V4 instance which is faster than selfhosting it for most things
even without "vision" it still has enough understanding of math and geometry to analyze things through building harnesses and even using playwright to analyze screenshots and whatnot which even without "vision" it still works good enough tbh
character isnt made by the AI tho, it's from mixamo directly but the terrain, sky, textures and everything else is the AI
it was able to debug characters animations and whatnot which few months ago with different models it wasnt able to yet, there's some progress and it's free, dont need to go broke on that
