prompt(messages=[...]) to pass a full array of messages

[simonw]

Need this to support implementing a Chat Completions API.

I had Claude Code Interpreter do some experiments around this, details in this transcript: https://claude.ai/share/9d5b0729-b58d-4b15-9e45-ab1e7152b89e

And this branch commit: https://github.com/simonw/llm/commit/697636222a277f892dfffef86b2471cc89c95576

Most interesting of which is this document:

• https://github.com/simonw/llm/blob/697636222a277f892dfffef86b2471cc89c95576/message_matching_notes.md

My initial idea for a design looks like this:

response = model.prompt(messages=[
    llm.System("you are a useful assistant"),
    llm.User("Capital of France?"),
    llm.Assistant("Paris"),
    llm.User("Germany?")
])

I guess you could do this as a shortened version:

from llm import User as U, System as S, Assistant as A

response = model.prompt(messages=[
    S("you are a useful assistant"),
    U("Capital of France?"),
    A("Paris"),
    U("Germany?")
])
