The answer to which ai model, in mid 2026, is always qwen. Depending on your ram, it’s qwen3.5-9b, qwen3.6-35b-a3 in a 3 or 4 bit quant, or qwen3.6-27b. I’m told a bigger model quantized is better than a smaller model unquantized. In 16Gb vram on 10 year old hardware i can run a 3bit quant of qwen3.6-35b-a3 at ~30tokens/sec, and it can do a lot.
