Running GPT-6 Astra? Can REPLAY scan your corpus and get the statistical data?

I built Replay to find where prompt caches break and what that costs you. It can already read Astra's rollout files. The problem is I don't have any Astra traffic to point it at.

Here's the honest situation. Replay reads the same rollout format Astra writes, and it knows Astra's pricing and cache rules. But I've never actually measured an Astra session, because I can't afford to generate the traffic. When there's no data, Replay says NOT MEASURED instead of guessing. The site says the same thing.

So I'm asking directly. If you're running Astra on real work

go install github.com/RedRobotKK/Replay/cmd/replay@latest

replay codex

It reads ~/.codex/sessions and ~/.codex/archived_sessions and gives you token counts. Everything stays on your machine, nothing gets sent anywhere.

Two things to know first. replay codex shows tokens, not dollars. And OpenAI doesn't publish a price for gpt-5.1-codex-mini, which is probably what you're running most, so nothing can price it.

What I actually want to know is simple: do your Astra sessions record token counts at all? Mine don't. That's the whole reason I have nothing to show you.

Post what you get and I'll publish the results with dates and sources, same as every other number on the site. Think of it as SETI@Home but for AI usage.
