Create Recursive GPT Functions Example

And we should also set it up to support both Kafka and Cloudflare Queues. I think that this example could actually become the next version of GPT.DO, as we need the ability to get completions not only from REST API invocations, but also on Kafka messages or Cloudflare Queue messages. Sending a message to a queue from any worker is an incredibly simple API ... and the new Mongo/Kafka integration could also be a very interesting and unique use case for this as streaming data could get completions.
