Category	model	model
Vendor type	open source	commercial
Pricing	free	usage
Strengths	+ MIT-licensed open weights + Designed specifically for agentic and tool-use workloads + Sparse attention architecture reduces long-context serving cost + 40B active parameters keep inference cost moderate for its class	+ First-class integration with OpenAI Agents SDK and Codex CLI + Broad ecosystem of tooling and integrations
Tradeoffs	− 744B total parameters still demand multi-GPU infrastructure to self-host − Smaller first-party API ecosystem than DeepSeek or Alibaba	− Lock-in to OpenAI platform features (e.g., Responses API)
