I need to read it into memory first so I can calculate the correct length for the upload.

Here's a weird detail:

https://github.com/simonw/llm-whisper-api/blob/3a037aef3fd6e12355f377b37fa757b2d0440229/llm_whisper_api.py#L52-L53

If you omit the filename, the OpenAI API returns a 400

If you leave off the .mp3 extension (I tried just audio_file.name = "audio") you get a 400.

But... it turns out you can send .wav data or .mp3 data with the same audio.mp3 filename and both work just fine.

This works now:

I need you to pretend to be a California brown pelican with a very thick Russian accent, but you talk to me exclusively in Spanish. How's your day today? And you, amigo, how was your day?

(Note it auto-translated from Spanish to English even though I didn't ask it to.)
