Strongest: Grok 4.7

Grok 4.7 is xAI's flagship model for coding, agentic tasks and knowledge work, announced and released to the public API on 2026-09-21 (xAI's pages now carry the SpaceXAI name). It is a reasoning-always-on model with a new, larger base model than Grok 4.6, a 500,000-token context window, text and image input, and xAI's server-side web and X search tools. xAI's own launch table puts it level with GPT-5.6 Sol on hard coding benchmarks at half Sol's input price and under a third of its output price. The sentence a buyer needs: Grok 4.7 is the most credible coding and knowledge-work model xAI has shipped, priced at $2 / $6 per 1M tokens, but on release day every performance figure is xAI's own, and it gives up Grok 4.3's 1M context and batch discount.
