There was a problem hiding this comment.
@corbt I don't think this works - gives you TypeError: Completions.create() got an unexpected keyword argument 'cache_salt'
I think you can replace with something like:
extra_body={
"cache_salt": "tenant-a-user-123-secret",
},

Summary
Add a new W&B Inference docs page for prefix caching and cache isolation, and add it to the English Inference "Response Settings" nav.
Motivation
Motivating Slack thread:
https://weightsandbiases.slack.com/archives/C08RU04P36G/p1774553788470369
A customer is worried about security on a multi-tenant installation, and we want to show that we take that concern seriously. This page explains how prefix caching works at a high level and how
cache_saltcan be used to isolate cache reuse across trust boundaries.Notes
