Grok 3 is xAI's most advanced model, trained on the Colossus supercluster with 10 times the computational power of previous state-of-the-art models. It boasts a 1M-token context window and advanced reasoning capabilities, enhanced through large-scale reinforcement learning, enabling deep thought processes ranging from seconds to minutes for solving complex problems. The model achieves top-tier performance across academic benchmarks and real-world user evaluations, earning an Elo score of 1402 in the Chatbot Arena. It was released alongside Grok 3 Mini, a cost-efficient variant optimized for streamlined reasoning.
Claude 3.7 Sonnet is Anthropic's most advanced AI model yet and the first hybrid reasoning system on the market. It offers both standard and extended thinking modes, with the latter providing transparent, step-by-step reasoning. The model demonstrates significant improvements in coding and front-end web development, achieving state-of-the-art results on SWE-bench Verified and TAU-bench. Available via Claude.ai, the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI, it sets a new standard for intelligent AI-powered problem-solving.
