As a coda to this, anyone using grok 4.6 via API pricing should be aware that while their headline pricing is good, the pricing that actually matters is pretty bad.

Their cache read costs are $0.50 per million, or 25% of the cost of uncached reads.

The industry standard is a 90% discount, so cache costs you 10% of uncached. So that means 5.6 Sol actually costs less per million cache reads - $0.40/million.

If you are doing a lot of agentic work where the vast bulk of your token consumption will be cached input reads, you won't get the expected cost savings from Grok.

I imagine this is the result of some problem in their serving infrastructure that I hope they will fix, because then the pricing will become actually strong. (The other possibility is that they bet on distracting people with good headline prices assuming they'd miss the bad cache pricing, but I'll give them the benefit of the doubt on that.)

> Not mentioning Grok 4.6 here is a crime.

Not yet. Don't give the guy ideas.

Been working a lot recently with Grok 4.6 for implementation and gpt 5.6 sol for review. Worked really good so far.

I would not use Grok if it paid me per token… wild wild stuff…

Speaking of crimes, the guy behind Grok not only manipulates it for propaganda purposes, but also he's the guy responsible for this: https://www.doge-impact.org/

Anyone using Sam Altman's OpenAI is making a poor ethical decision, but anyone using Grok is, objectively, supporting a monster.
