Grok 4.7, with 500K tokens against 256K on Grok Build 0.1. The window holds your instructions, the files you attach, the conversation so far and the answer, all at once.

Yes, both are counted the same way: our lesson "How AI writes", 1,700 words long, is about 2,100 tokens on each.

No, it costs more per token: Grok 4.7 charges $2 per million tokens read and $6 written, against $1 and $2 on Grok Build 0.1, 2.4 times as much for the same tokens. It pays off only if better answers save more than that, for example in fewer retries.

Not with a batch price: neither maker's price page lists one for these models. A cache still lowers the price of text the model reads again.
