Which Tool Should You Pick?
Pick OpenAI GPT-5 API if…
- You need state‑of‑the‑art language model performance with 1‑million‑token context windows.
- You are building your own agent system from scratch and want maximum flexibility.
- You have the budget for high token costs ($15/M input, $60/M output) and don't require self‑hosting.
Pick CrewAI if…
- You need to coordinate multiple AI agents with distinct roles, goals, and tools.
