Is there a convenient way to make sequential gptel-request?

[101scholar]

When the stream option is set to t, I want to chain multiple gptel prompts so that once one completes, the combination of all prior inputs and outputs, together with current output and the new prompt are sent as the input for the next gptel-request.

Is there a convenient way to do so, and what is your best practice suggestion? Maybe callback function?

Use gptel-post-response-functions to modify the buffer as you want and run gptel-send.

For more fine-grained control you can use gptel-request and the finite state machine. This approach is probably not required -- changing the state machine configuration is more work but also more powerful -- you can do almost anything involving instruct-LLMs and Emacs, including building entire new gptel-based packages.
