OpenAI Flex Processing and webhook gaps

From OpenAI

Looking into OpenAI Flex Processing for cheaper asynchronous workloads. The pitch is simple: lower-cost processing for tasks that don’t need an immediate response.

The catch for us in Europe: OpenAI webhooks aren’t available here yet. Without webhooks, there’s no clean push notification when a long-running job finishes, so we’re stuck polling or building our own completion-tracking layer.

Alternatives to explore:

• AWS Bedrock: may have better async/notification support in EU regions.
• Azure OpenAI: often has different regional availability and webhook/eventing options.

For now, Flex Processing is on the list, but only if the polling overhead is worth the cost savings.
