Day 0 Support: Grok 4.7

LiteLLM supports grok-4.7 on day 0, on /chat/completions and /responses. It keeps Grok 4.6's prices, limits and capabilities.

SpaceXAI, the company formerly called xAI, built 4.7 and reports the model is better at checking its own work and holding long context. Against Grok 4.6, Terminal-Bench 4.0 goes from 20.3% to 38.0% and EEBench from 53.0% to 64.0%.

Pricing

Per 1M tokens: $2.00 input, $0.50 cached, $6.00 output, identical to Grok 4.6. Every rate doubles past 200K input tokens, to $4.00, $1.00 and $12.00, so a long-context request costs twice what the headline suggests.

Usage

SDK

from litellm import completion

response = completion(
    model="xai/grok-4.7",
    messages=[{"role": "user", "content": "Refactor this migration script."}],
    reasoning_effort="xhigh",  # low | medium | high (default) | xhigh
)

print(response.choices[0].message.content)
