From the press release at least it sounds more expensive than Opus 4.5 (more tokens per request and fees for going over 200k context).

It also seems misleading to have charts that compare to Sonnet 4.5 and not Opus 4.5 (Edit: It's because Opus 4.5 doesn't have a 1M context window).

It's also interesting they list compaction as a capability of the model. I wonder if this means they have RL trained this compaction as opposed to just being a general summarization and then restarting the agent loop.

On Openrouter it has the same cost per token as 4.5

That's a feature. You could also not use the extra context, and the price would be the same.

		The model influences how many tokens it uses for a problem. As an extreme example if it wanted it could fill up the entire context each time just to make you pay more. The efficiency that model can answer without generating a ton of tokens influences the price you will be spending on inference.
