xAI's Grok model for chat, coding, agentic tools, and lower hallucination risk
Grok 4.5 by xai is offered by 26 providers on this page. Public prices are shown for 25 of them. Its official list price is $2.00 per 1M input tokens and $6.00 per 1M output tokens. It also has 1 free ($0) channel; free tiers usually carry rate limits, and subscription-covered access bills $0 per token only after the subscription fee.
Artificial Analysis rates it 55.8 on the Intelligence Index, with 72.4 for coding and 48.9 for agentic tasks. Against its lowest blended price of $3.00 per 1M, that is roughly 19 index points per dollar, which is the value ratio the leaderboards rank on. Median output speed is 48 tokens per second, with 12.68s to the first token. Running one task of the Artificial Analysis suite costs about $0.4256, which reflects how many tokens its reasoning consumes rather than the unit price alone.
The context window is 500,000 tokens at the reference host, but hosts report different limits, from 500,000 to 1,000,000, so the usable window depends on the provider you pick. It supports reasoning, tool use, and structured output. Accepted input modalities are Text, Image, and PDF.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
1 more channels offer $0 (Kenari); free tiers usually have rate limits and no SLA, excluded from ranking.
