OpenAI's $200 Codex plan now delivers roughly $2,000 of inference per month, down from $12,000. The value hasn't disappeared, but teams need to switch to GPT-6.1 Soul and treat Astra cautiously.

Subscription AI pricing is shifting from unlimited to metered, affecting team budgeting and model selection.

Watch if you manage AI tooling budgets and need granular math to decide between Codex and Claude subscriptions.

Summary

The value collapse. OpenAI's $200 Codex plan once delivered up to $12,000 of monthly inference. Recent changes have cut that to roughly $2,000, a 10x drop. The creator of T3 Code walked his own usage data, showing $573 of value from a full week of heavy use. This is not a perception problem. The numbers are materially worse.

Why it happened. The subsidization arms race between OpenAI and Anthropic became unsustainable. Both labs priced subscriptions as loss leaders to capture developer mindshare, but model costs rose and usage patterns shifted from occasional prompts to intensive agent-driven workflows. OpenAI had to tighten limits or face runaway compute costs.

The hidden tradeoff. Subscribing to use GPT-6.1 Soul instead of Astra actually stretches value further. Soul is dramatically cheaper per token and per task. On Terminal Bench, Soul scored nearly as high as Opus 5.5 at one-thirteenth the cost per task. The plan still delivers strong practical output, provided you avoid the expensive models.

Where Claude wins. The Claude $200 plan offers Opus 5.5 usage that remains effectively unlimited for heavy coding workflows. Anthropic restricts model access more strictly, but for shipping production code, the value is superior. The speaker runs six Claude accounts and drains them regularly.

The $500 plan blunder. OpenAI launched a $500 tier with access to ultrafast inference on Astra, but ultrafast burns through the weekly limit in roughly two hours of generation. The speaker calculated $1,000 of ultrafast value per week versus the $12,000 the old $200 plan offered. This was an optical disaster layered on top of a real cut.

What to watch. The competitive pricing pressure is collapsing margins. Labs are moving from 95% margins toward 50% on certain models. Over the next year, subscription subsidization will continue shrinking, but the raw work output per dollar will still improve because the models themselves are becoming more efficient. The drama is real, but the practical trend is positive.

My take

The fanboy wars are entertaining, but the practical signal is clear. For shipping production code, Claude's $200 plan still feels unlimited and delivers better model performance. Codex is now a secondary tool for review and cheaper tasks. The $500 plan is a trap for anyone not running a specialized benchmarking pipeline. I'd tell my team to treat the $200 Codex plan as a supplement, not a primary subscription. The real surprise is that GPT-6.1 Soul is so efficient at its price that even after the cuts, the raw work output per dollar might still be improving for coding workflows. That's the part most angry takes are missing.

What to do with this

  1. Compare your team's monthly AI subscription costs against actual output tokens and tasks completed.
  2. Pilot Claude's $200 plan for primary coding tasks for two weeks before renewing Codex subs.
  3. Set a policy against using ultrafast tiers unless a clear cost-benefit analysis shows returns.
