DeepSeek V4 Pro and Grok 4.6 launch on the same day as early tests show a tight race
DeepSeek V4 Pro and xAI’s Grok 4.6 arrived on the same day, setting up a direct comparison across benchmark scores, pricing, and real task execution. DeepSeek V4 Pro posted strong results in CyberGym, AutomationBench, Terminal-Bench 2.1, and DeepSWE, in several cases beating Opus 4.8 and narrowing the gap with Fable 5. Grok 4.6, meanwhile, kept pace in broader capability rankings and moved ahead in several coding and knowledge-work evaluations, including GDPval-AA v2, AA-Briefcase, and Harvey LAB. Pricing became another focal point. DeepSeek listed output pricing at $0.87 per million tokens, compared with $6 for Grok 4.6, $30 for GPT-5.6 Sol, $25 for Claude Opus 5, and $50 for Fable 5. Early hands-on tests cited in the source showed the two models trading wins across website creation, design generation, frontend work, and game-building tasks. In one Flappy Bird comparison, DeepSeek used more than 20,000 tokens at a cost of $0.019, while Grok used about 5,000 tokens at a cost of $0.03. The resulting DeepSeek version was described as more polished. The source’s overall takeaway was that the two newly released models are now operating at roughly the same level.
