Best-in-class for long-form reasoning, analysis, and structured outputs. The model I reach for first.
Free tier available. Pro at $20/mo. API usage-based.
Best for
Teams building AI workflows that need reliable, nuanced outputs — especially writing, analysis, code generation, and data extraction.
Not for
Anyone who just needs quick one-line answers or real-time web search built in. Not ideal if your workflow depends on image generation.
Strengths
Where it performs well.
- Consistently high-quality long-form writing — doesn't lose coherence at length
- Best structured output reliability of any model (JSON, XML, markdown)
- Handles complex multi-step instructions without drifting
- System prompts actually work — you can steer behavior precisely
- API is clean and well-documented, easy to integrate into workflows
Limitations
Where you should be careful.
- No native web browsing — needs external tool integration for real-time data
- Knowledge cutoff means you need to provide current context explicitly
- Rate limits on the API can bottleneck high-volume production workflows
- Image understanding is solid but image generation is not available
Verdict
Use
The default choice for any serious AI workflow. Particularly strong for anything involving writing, reasoning, or structured data. If you're building business automations, start here.
