How long does each AI provider keep your prompt cache?

Don't trust their documentation. We measured it with >60,000 requests to 14 providers over 32 hours, through day and night, and several providers' caching docs turned out to be wrong

We measured so that Mainplane can use the best settings we found for every provider, and save on your AI bill

Mainplane v0.5.11 released!

We heard your feedback: you want to run it more locally, without dependance on cloudflare or pointer.mainplane.ai

So we added two new install options:

--no-pointer: your machines never contact pointer.mainplane.ai
--no-admin: agents cannot reach the harness machine
If you pair these with adding your own URL, no traffic goes through Cloudflare or to pointer.mainplane.ai

See the full changelog here: github.com/mainplane-ai/m…

Mainplane agents can orchestrate across multiple devices!

Watch one agent create new sessions on a macbook, windows laptop, and linux VPS

And the twist: the whole video was scripted, recorded, and edited by Mainplane itself
