Grok 4.6
SpaceXAI · Released Aug 2026
Conditional
Frontier-competitive at $2/$6 with a 61 AA Intelligence Index (ties GPT-5.6 Sol) and GDPVal-AA behind only Claude Opus 5 — strong out of the gate, but one evaluator deep and one day old, so hold production bets until broader benchmarks land.
Is it right for you?
Good for
- Expected to lead on token efficiency and per-task cost among frontier models, continuing Grok 4.5's ~4x token savings on coding tasks
- Trained alongside Cursor IDE data for strong repository-scale coding and agentic task performance
- Targets ~80 TPS throughput with custom C/C++ inference for fast iteration loops
Not good for
- Strictly capped at 500K context, not 1M+ — Anthropic and Google offer larger windows for long-document work
- EU availability may lag behind US launch, as was the case with Grok 4.5
- No independent benchmarks or third-party evaluation available yet — all claims are vendor projections
