Grok 4.6

xAIflagship

Released 12 Aug 2026, scoring 44 on the Artificial Analysis Intelligence Index v4.3 at high and xhigh effort (43 at medium), rank #21 of 199, at $2/$6. The notable spec is the one that moved the wrong way relative to the field: a 500k context window, against 1M for almost every other frontier model on this board. For most work that is academic — 500k is around 750 A4 pages — but it rules out the whole-repository and whole-corpus patterns that the 1M-context models have made routine. Output speed is 64.5 tokens/second, just under the 68 tok/s median, with a 75% cache discount bringing the blended rate to about $1.35 per 1M. Text and image in, text out, reasoning model. Note that Artificial Analysis now lists the creator as SpaceXAI.

Cheaper is left, more capable is up. 2 of 62 priced models are both cheaper and score at least as high. Self-host models are left off the price axis — their cost depends on the hardware you run them on, not on tokens.
