Grok 4.3 vs Llama 4 Scout
Benchmarks, API pricing and specs, head to head. Data updated 2026-06-10.
xAI · Apr 2026
xAI's frontier model: 1M context at $1.25/$2.50, ~168 tokens/sec, and a record low hallucination rate on independent testing.
Meta · Apr 2025
A 10M-token context window — still the largest ever shipped — in a 109B MoE that fits on a single H100.
The verdict
These two models don't yet share verified results on the benchmarks we track, so judge them on specs, pricing and intended use. On price the gap is dramatic: Llama 4 Scout works out roughly 5.5x cheaper per blended million tokens. Llama 4 Scout also takes 10M of context versus 1M for Grok 4.3. And Llama 4 Scout is open-weights (Llama 4 Community License), so it can be self-hosted — a structural advantage if data control or vendor independence matters.
