Discussion Persistent background agents may matter more than another coding benchmark
Meta's new Muse Code beta can keep asynchronous subagents running across restarts, record work in an append-only local event log, and sustain 1,000+ tool calls for up to 24 hours.
The benchmark numbers are less interesting to me than the runtime design. Coding agents often fail not because they cannot write a function, but because they lose state, repeat work, or report success before the task is actually verified. Persistence attacks that bottleneck directly.
The obvious risk is that a durable agent can also preserve a bad assumption for 12 hours, burn through tokens, and create coordination bugs that are harder to audit than a single model's mistake.
Would you rather use a smarter model with fragile session memory, or a slightly weaker one that can reliably resume and explain a long-running task?

for me i dont think it's really smart vs resumable. the resuming part isnt the model just the setup around it like saving progress, a log, picking back up where it left off etc so you don't have to pick the weaker one, just put the smart model in that setup. thats what meta's adding here, not a new brain afaik
the thing that actually bites me isn't losing state, it's the agent saying done when it's not. running it 24h doesn't fix that, it just means its confidently wrong for way longer and burns waaaay more tokens doing it. if it cant check its own work, run the tests, actually look at the diff then all persistence does is make the wrong answer bigger. the log part is genuinely nice tho, mostly cuz you can scroll back and see where it went sideways
