Our take
Written Sep 3, 2026Grok Latest is xAI's proprietary flagship, built for deep-document and long-form work where retaining hundreds of thousands of tokens matters. Its half-million-token request limit is among the longest we track, though no benchmark scores are available to measure quality.
Pick this for long-context workflows that need to retain 500,000 tokens of information in a single request, or when routing through the cheaper hosted option to keep output costs down. Skip it if you need measured quality data, if you want to self-host, or if your budget cannot absorb premium per-token pricing.
The case for it
- Exceptional context length for extended documents and conversations, at 500,000 tokens.
- Accepts text, images and files, making it usable for multimodal long-context work.
The case against it
- Expensive at direct pricing, with a markedly higher output rate than the cheaper hosted route for the same model.
- No measured quality scores in our data, so there is no independent evidence of capability.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
Where to rent it

The lab is also the cheapest we hold. The strip above and this offer are the same one, so nothing on this page undercuts xAI on 500K of context.

What each host's API supports
From the parameter list each endpoint publishes. Streaming is omitted: nothing we hold reports it, for any model.

What we do not know about this model yet
- No independent board has scored it, so we hold no quality figures at all.
- 1 of 2 listings publishes no parameter list, so what its API accepts is unknown to us.
- Nothing we hold says whether an endpoint streams, so we do not show it either way.
- 2 of 2 listings do not say whether they train on prompts.
- We hold no batch or off-peak rate for any of its listings.
