Run parallel local coding agent sessions
A developer runs up to 10 coding agent sessions at once, using Claude Code and local models on RTX 3090s with cached contexts for daily development work.
What they did
Roark66 runs coding agents on RTX 3090s with 24GB each, using Claude Code alongside local models. They keep up to 10 agent sessions open at once, though never more than 5 are active at the same moment. Because they control inference, they keep full contexts cached in RAM and can save the cache to disk, so a session isn't re-read in full after sitting idle.
How it went
Holding about 15 full contexts cached in RAM pushes their local cache utilisation to 95% or more. They say their usage of roughly 1.3B input tokens a week would cost thousands of USD at API prices.
Worth knowing
Cloud caches expire after 5 minutes or 1 hour, so an idle 500k context gets billed as full input again; local caching avoids that, but you need enough RAM to hold the contexts.
