I have a lot of hobby projects and cannot afford to drop $200/m for assistance from LLMs with above average intelligence. The Chinese models work quite well, and are cost effective, in comparison. My usage over the last few months:
- Gemini / AI Studio = translations
- Kimi 2.5 / OpenCode Go = Compiler/VM project, AI for some board games, a new document format and compiler for it,
- DS4 Flash / DeepSeek (had some credits lying around) + OpenCode Go = Template-based OCR engine
- MiMo 2.5 and MuseSpark 1.2 Contributor = The OCR engine + a product I am brainstorming + a lot of single page tools
If you select models judiciously, and can write good AGENTS.md and extremely short but potent ARCHITECTURE.md documents, the $10 you pay to OpenCode Go will last a long while even when you consume a hundreds of millions of tokens (mostly cache hits) a day. You can get multiple models to perform code review of modules against the ARCHITECTURE you have specified and get other models to execute the fixes.
