Interestingly github-copilot is charging 2.5x as much for opus 4.7 prompts as they charged for opus 4.6 prompts (7.5x instead of 3x). And they're calling this "promotional pricing" which sounds a lot like they're planning to go even higher.
Note they charge per-prompt and not per-token so this might in part be an expectation of more tokens per prompt.

Not that anybody can actually use it though, as a large percentage of Copilot users are facing seemingly random multi-day rate limits.

> Opus 4.7 will replace Opus 4.5 and Opus 4.6
Promotional pricing that will probably be 9x when promotion ends, and soon to be the only Opus option on github, that's insane
