Theo: a $200 Claude sub buys $9,000 of Opus

Theo ran three Claude accounts to zero since Opus 5.5 shipped and priced the usage at roughly $2,200 a week each. Meanwhile OpenAI is halving what a $200 Pro plan is worth in API terms, and dax says nobody should be surprised.

The big disagreement

OpenAI halves what $200 Pro buys, dax tells people to stop screaming

Tibo says OpenAI is reopening $200 Pro subscriptions and changing how usage is calculated, netting out at half the API spend of the old plan, with no return of the 5 hour limit and GPT-6 Sol and Luna already cut to 50% of their previous price.

Receipts

Theo: a $200 Claude sub bought him about $9,000 of Opus usage

Theo says he has run three Claude accounts down to 0% since Opus 5.5 landed, and priced the usage at $2,086, $2,442 and $2,182, averaging $2,200 a week. That works out to roughly $9,000 a month against a $200 subscription. The figure is his own accounting of his own accounts, not an Anthropic number.

Theo corrects himself: Opus did not fix Astra's port, it threw it away

Theo now says he was wrong about how Opus 5.5 finished his TypeScript compiler port to Rust: it did not resume where Astra stalled, it judged all of Astra's code slop and rewrote from scratch in a new crate. By his count it made more progress in 10 hours than Astra did in two weeks.

It actually decided all of Astra's code was slop, and made an entirely new crate with a from-scratch rewrite.
