OpenAI AgentKit

OpenAI first-party agent toolkit — a visual Agent Builder, embeddable ChatKit UI, a connector registry, and evals, billed at plain API rates.
Overview
AgentKit is OpenAI answer to "we gave you an API and you built the same scaffolding four times." Agent Builder is a visual canvas for composing and versioning multi-agent workflows; ChatKit drops a production chat surface into your own product; the Connector Registry gives admins one place to manage data connections across OpenAI products; and the evaluation tooling closes the loop. The commercial appeal is that there is no platform fee — designing in Agent Builder is free and you pay standard model and storage rates, so the cost curve is the API cost curve you already understand. That is a meaningfully different proposition from credit-metered platforms like Agentforce or Copilot Studio. The tradeoff is lock-in to one model provider at the orchestration layer, which is exactly what LiteLLM, Portkey, and OpenRouter exist to avoid.
Pros & Cons
Pros
- No platform fee on top of API usage
- Visual workflow builder with versioning
- ChatKit ships a production-ready chat UI
- Evals are first-class rather than an afterthought
- Cost model is the API cost model you already forecast
Cons
- Single-provider lock-in at the orchestration layer
- Agent Builder and Connector Registry have been in beta rather than fully GA
- Fewer enterprise governance controls than Copilot Studio or Agentforce
- No managed hosting story comparable to Bedrock AgentCore
