Part of it tracks how many tokens you actually get from various subscriptions, over time.

Past week, multiple people asked me about it — they'd been hitting Claude and Codex limits faster than expected.

Ran the tests yesterday. Reran today. Here's what came back: ▸ ChatGPT Plus / GPT-5.5: 95M → 37M tokens/week (−61%) ▸ Claude Max 20× / Sonnet 4.6: 388M → 214M (−45%) ▸ Claude Max 20× / Opus 4.7: 248M → 162M (−35%) ▸ Claude Pro / Sonnet 4.6: 19.6M → 11.4M (−42%) ▸ Claude Pro / Opus 4.7: 15.6M → 10.2M (−35%)

5 of 5 retested plans dropped 35-61% in five days. None went up.

Anyone else seeing similar in their own usage?

Is the AI itself degrading? Or is it because of product-policy changes, such as system prompt modifications and usage limits? Or is it both?

I sometimes wonder whether degradation is simply an inherent property of LLMs themselves.

Not a criticism of this project — it's a good idea, it just highlights the central question of "how well is this model working?" I'm not sure it's so straightforward.
