Grok 4.20 deployment guide
How to choose a Grok 4.20 inference provider
Grok 4.20 is indexed here as a text model by xAI, with 4 provider endpoints from xAI. The comparison preserves each exact OpenRouter routing tag so pricing and performance observations can be connected to the route an application would actually request.
Match the endpoint to the workload
The model publishes a 2M-token context window. It accepts text, image, file input and returns text output. 12 distinct supported parameters appear across the listed routes. Confirm limits on the specific endpoint rather than assuming every host exposes the same configuration.
Compare the real request economics
xAI currently has the lowest estimated cost for the standard 1,000-input/500-output-token sample at $0.0025. Input-heavy and output-heavy applications can produce a different result, so review both per-million-token prices in the endpoint table.
Balance response start and generation speed
xAI currently has the shortest estimated 500-token response at 5.48 seconds. xAI is the single endpoint closest to the current ideal cost/speed combination. Recent observations can change, so validate finalists with your own prompts.
