The premise is that price-per-token is the product.
It is not.
A model that works longer without a verifier is just a more expensive unfinished task.
Who ships the stop condition wins the week, not the $2 input line.
DON'T BE FOOLED BY GROK 4.7.
xAI released a bigger model yesterday and didn't raise the price:
$2 per million tokens in, $6 out. Anthropic's Fable costs 5x that on input and 8x on output.
Elon Musk posted a chart of score against cost, and on it Grok looks like the best deal on the board.
Then an independent lab counted what it spends to finish a job.
Grok 4.7 at its top setting uses 81,000 output tokens per task. The old Grok used 36,000. OpenAI's GPT-5.6 uses 27,000.
On that test, the finished task costs $3.74. The same task on GPT-5.6 costs $1.99.
You pay less per token and more per job.
