xAI posted Grok 4.6 on Aug 12 2026 as a post-training refresh of Grok 4.5 at the same $2/$6 API price and 500k context. We updated the seed snapshot that week. This site does not score “live X search” or personality. Preference Elo, SWE-bench, TTFT, and list price are the columns. The Grok vs ChatGPT hub always points at the current top xAI vs top OpenAI Elo rows.
Refresh ≠ new slug on every tweet
We aliased “grok 4.5” to this row so ingest does not mint a preview twin. If a later Grok 5 ships with a new OpenRouter id, it will land as preview until a second source matches or an admin promotes it.
Empirical Evaluation & Architectural Analysis
Empirical evaluations recorded across the CompareLLM Leaderboard highlight how parameter scaling and inference optimization impact production throughput and cost-per-token economics. Reference the interactive scorecard above for verified snapshots or inspect the dedicated grok-4-6 dossier.
What “leads Elo” means here
If Grok 4.6 leads preference Elo, humans preferred its anonymous replies more often. That is not a science exam. Read /guides/what-is-elo before you rip out Sol.
