Grok 4.5

Grok · Released 2026-07-08

xAI's July 2026 frontier release. Artificial Analysis Intelligence Index 53.8 (high-effort setting) — above Grok 4.3 and in the current top tier with Claude Opus 4.8 and GPT-5.5. API list price $2 / $6 per 1M tokens.

Frontier xAI model for long-context and freshness-sensitive work. Prefer sourced ledger rows over marketing claims; AA scores sync from the public snapshot.

5 tested benchmark families

Editor's note
Tool scaffolded from the 2026-07-09 AA snapshot (slug grok-4-5, high effort). Editorial depth and failure modes still need a desk pass — scores below are ledger-backed, not hands-on claims.
Benchmark placements

Where Grok 4.5 places on each public benchmark source that publishes a row. Rank counts every model with a latest row in the same test — not a universal quality score.
