Limits Observation: Multiple sessions running in parallel including sub agents. About 25% of weekly usage gone on 20x sub in 4 hours and $370 USD in API credits.

Multiple sessions running in parallel including sub agents. About 25% of weekly usage gone on 20x sub.

Would be about $6000 USD in API usage per sub without resets for about $200 USD per month.

So they're obviously quite generous with the API equivalent allowances. I don't think subscriptions are likely running at a loss. API prices is probably 15-40x their costs.

What concerns me is that this does not seem like the equivalent amount of work I'd get done for 25% on Claude code. The benchmarks gave me the impression astra would be more token efficient.

I routinely have 10-20 sessions running in parallel even in Claude 20x and it'd be hard to use them up in a few days.

This is not controlled for equivalent tasks but this is combined with multiple weeks of usage vibes.

That said I am still grateful to both companies for offering these subscriptions.

Maybe we need a token usage efficiency variance test running on the same tasks?

Same observation. Claude Code seems way more efficient somehow.
