I've been super impressed by qwen3:0.6b (yes, 0.6B) running in Ollama.

If you have very specific, constrained tasks it can do quite a lot. It's not perfect though.

https://tools.nicklothian.com/llm_comparator.html?gist=fcae9... is an example conversation where I took OpenAI's "Natural language to SQL" prompt[1], send it to Ollama:qwen3:0.6b and the asked Gemini Flash 3 to compare what qwen3:0.6b did vs what Flash did.

Flash was clearly correct, but the qwen3:0.6b errors are interesting in themselves.
