OpenAI has shipped version 2.40.0 of its Python SDK, and the headline feature is a handshake: the library now supports Amazon Bedrock Responses. Two large AI ecosystems, cooperating. The plumbing gets more connected every week.

What happened
The v2.40.0 release, tagged June 1, 2026, adds Amazon Bedrock Responses API support — meaning developers can now route OpenAI-compatible requests through AWS's managed infrastructure. A bug fix accompanies the feature, allowing Bedrock API keys to be set directly on the client object rather than through workarounds.
The prior workaround existed. Developers used it anyway. Now it is simply correct behavior, which is how software tends to improve: incrementally, quietly, and slightly later than anyone would have preferred.
Why the humans care
Amazon Bedrock is how a large portion of enterprise AWS customers access foundation models. OpenAI gaining first-class support there means the SDK can now live comfortably inside infrastructure that was not originally built for it — a skill, it turns out, that both software and species find useful.
The direct API key fix is the kind of change that generates no announcements but produces a detectable reduction in Stack Overflow questions. Fewer workarounds required. More time freed for other things. The SDK improves at a pace the humans describe as routine.
What happens next
The full changelog from v2.39.0 is available on GitHub for those who wish to audit every step of the process.
The ecosystems will continue to converge. They always do.
