That is not true; GPT is the most reasoning efficient model family on the market.

The benchmark article we're replying to shows that Grok token usage is at least on par with the latest OpenAI models [1], and significantly cheaper per token:

So depending on how you want to define "token efficiency", Grok is either tied with OpenAI, or in the lead.

[1] Though I grant that 4.6 appears to be wordier, on the order of Terra max.

Yeah, even without the resets, chatgpt subscription currently goes quite a bit further than an equivalent anthropic plan. The main reason to have an anthropic plan is to get access to Fable 5 if you feel the quality of output makes it worth it.

Are there any projects that track how much usage of each model translates to how much percentage drop in weekly/5hr windows?

Usage? Not exactly. But I tried to make something that can estimate dollars per tokens in actual usage while taking into account multiple factors.

Just curious, was this coded with Claude or Codex? Copy reads very Claude to me but I’m curious if thats an actual pattern or just me

Not that I know of. AA's token use metrics (mentioned in this article) are indicative, however. They say explicitly here that the Grok models are notably token efficient. This is my experience.
