About

Grok 4.6 is an xAI model designed for long-running agents, ambitious interactive projects, visual work, coding, research, and knowledge workflows. The model builds on Grok 4.5 with stronger support for multi-step tasks that require sustained reasoning across codebases, information analysis, application development, and work artifact creation. Grok 4.6 can help turn broad product ideas into working first versions by researching domains, structuring applications, implementing core interactions, and refining results through feedback. It is trained across agentic tasks such as knowledge work, general coding, kernel optimization, web development, computer-aided design, and other technical environments. The model is available in Cursor, Grok Build, the xAI API, and partners such as OpenRouter, Vercel, and Cloudflare. Built for developers, builders, and teams working on complex projects, Grok 4.6 helps accelerate coding, agentic workflows, visual applications, and technical execution.

About

Hy4 preview is a new-generation open source Mixture-of-Experts flagship model built for real-world productivity tasks across software engineering, office work, game development, and scientific research. The model contains 770B total parameters with 49B activated per token and supports a 1M-token context window, giving it the capacity to work through large codebases, extensive document collections, and long multi-step tasks. Its 78-layer architecture combines Gated DeepSeek Sparse Attention with IndexCache for cross-layer sparse index reuse and identity Hyper-Connections to expand information flow between layers. A native Multi-Token Prediction layer is included for speculative decoding. Hy4 preview is designed to understand, plan, debug, and verify long-horizon engineering tasks, with additional gains in front-end visual quality and interaction design.

Pros & Cons from Real Users

Pros

  • Grok 4.6 looks like a strong upgrade for developers who care about agentic work, not just quick answers. The focus on long-running tasks is exactly what I want when a model needs to stay with a codebase, reason through multiple steps, and keep making progress without falling apart. I also like that it is built for coding, research, visual work, and app creation in the same lane. That makes it feel useful for modern developer workflows where you are not just writing code, but also reading docs, planning architecture, generating UI ideas, and turning rough concepts into working artifacts. The benchmark positioning is impressive too. Matching GPT-5.6 Sol on Artificial Analysis’ Intelligence Index gives Grok 4.6 a lot more credibility as a serious frontier model instead of just another fast Grok update.

Cons

  • I would also want to see more independent developer feedback and a detailed model card. For production use, I care about reliability, latency, tool behavior, pricing, security, and how predictable the model is under pressure.
