How does this compare to the commercial models like Sonnet 4.5 or GPT? Close enough that the price is right (free)?
The will not measure up. Notice they're comparing it to Gemma, Google's open weight model, not to Gemini, Sonnet, or GPT. That's fine - this is a tiny model. If you want something closer to the frontier models, Qwen3.6-Plus (not open) is doing quite well[1] (I've not tested it extensively personally): https://qwen.ai/blog?id=qwen3.6
