The model, available via API, Cursor, Grok Build, and partners like OpenRouter, Vercel, and Cloudflare, excels on agentic tasks, ranking second on GDPval-AA v2 with an Elo of 1,753 and completing tasks in about 53 steps versus Claude Opus 5's 103.", "body_md": "# SpaceXAI's Grok 4.6 matches OpenAI's best model and undercuts it on price\n\n**Grok 4.6 catches up to frontier models while costing far less.** According to the [Artificial Analysis Intelligence Index](https://artificialanalysis.ai/articles/grok-4-6-benchmarks-and-analysis), SpaceXAI's new model scores 61 points, tying OpenAI's GPT-5.6 Sol. Only Anthropic's Claude Opus 5 (63) and Claude Fable 5 (62) score higher. That's a five-point jump over its predecessor, Grok 4.5.\n\nGrok 4.6 performs especially well on agentic tasks, where models independently carry out multi-step workflows. On the [GDPval-AA v2 benchmark](https://the-decoder.com/openai-says-top-ai-models-are-reaching-expert-territory-on-real-world-knowledge-work/), which aims to measure real-world knowledge work on a computer, it ranks second with an Elo score of 1,753, trailing only Claude Opus 5. It completes complex tasks in about 53 steps. Claude Opus 5 needs roughly 103.\n\nPricing stays at $2/$6 per million tokens. That's more than 60 percent cheaper than Claude Opus 5 ($5/$25) and GPT-5.6 Sol ($5/$30). Grok 4.6 is available now through the [API](https://console.x.ai/), [Cursor](https://cursor.com/), [Grok Build](https://x.ai/build), and partners like OpenRouter, Vercel, and Cloudflare. For the first week, x.ai is offering double the usage quota in Grok Build and Cursor.\n\n```\nAI News Without the Hype – Curated by Humans\n\n\t\t\t\t\tSubscribe to THE DECODER for ad-free reading, a weekly AI newsletter, our exclusive \"AI Radar\" frontier report six times a year, full archive access, and access to our comment section.\t\t\t\t\n\n\t\t\t\t\tSubscribe now\n```\n\n", "url": "https://wpnews.pro/news/spacexai-s-grok-4-6-matches-openai-s-best-model-and-undercuts-it-on-price", "canonical_source": "https://the-decoder.com/spacexais-grok-4-6-matches-openais-best-model-and-undercuts-it-on-price/", "published_at": "2026-08-12 18:33:21+00:00", "updated_at": "2026-08-12 18:50:20.812326+00:00", "lang": "en", "topics": ["artificial-intelligence", "large-language-models", "ai-products", "ai-agents"], "entities": ["SpaceXAI", "OpenAI", "Anthropic", "Grok 4.6", "GPT-5.6 Sol", "Claude Opus 5", "Claude Fable 5", "Artificial Analysis Intelligence Index"], "alternates": {"html": "https://wpnews.pro/news/spacexai-s-grok-4-6-matches-openai-s-best-model-and-undercuts-it-on-price", "markdown": "https://wpnews.pro/news/spacexai-s-grok-4-6-matches-openai-s-best-model-and-undercuts-it-on-price.md", "text": "https://wpnews.pro/news/spacexai-s-grok-4-6-matches-openai-s-best-model-and-undercuts-it-on-price.txt", "jsonld": "https://wpnews.pro/news/spacexai-s-grok-4-6-matches-openai-s-best-model-and-undercuts-it-on-price.jsonld"}}
