The Grok 4 Fast and Grok Code Fast models have really impressed me. The only issue I've had is reaching a rate limit on the Grok 4 Fast model. Amazing pricing for highly capable models with good tool calling support.
They're definitely amazing for the price. I like that you can do quick back and forth with them. but they're not very smart. When I need something to actually analyze or write good code and not just refactor and move things around, they're not good for that.
Agreed. For harder tasks, I like to go to GPT 5 thinking mode, but I'm considering other options.
Some times I've had faster success with some of the larger Qwen3 models (480B and 235B variants). I like them in combination with the Repomix CLI to copy an entire project into context and get a response very quickly with some of the accelerated providers like Cerebras.
Now that Cursor has moved towards a credits system, grok code fast is making the plan last while still being reasonable in inference time. GPT 5 and GPT 5 Codex actually moves my "amount remaining" bar in realtime while being incredibly slow.
