Grok 4.6 发布 · Cursor
原题Introducing Grok 4.6 · Cursor
推荐理由Cursor 与 SpaceXAI 发布 Grok 4.6，把重点放在长时 Agent、代码库协作、知识工作和交互式应用。官方称它在由 9 项基准构成的 Artificial Analysis Intelligence Index 上与 GPT-5.6 Sol 持平，并披露每百万输入 Token 2 美元、输出 Token 6 美元的起步价格。更值得关注的是模型在长轨迹中开始主动测试和验证自己的工作，这让模型竞争从单次回答转向持续交付。对开发者而言，值得继续验证的是这些官方基准和演示优势能否在真实代码库、长会话与多轮反馈中稳定复现。

Today we are releasing Grok 4.6 together with SpaceXAI.
Grok 4.6 builds on Grok 4.5 with a particular focus on long-running agents and more ambitious interactive and visual work. It stays with complex tasks across many steps, whether researching a topic, analyzing information, working across a codebase, or turning an idea into a polished application or work artifact.
Grok 4.6 achieves frontier intelligence across several agentic coding and knowledge work benchmarks. It matches GPT-5.6 Sol on the Artificial Analysis Intelligence Index, which is a composite score of nine benchmarks.
Grok 4.6 is available today in Cursor and Grok Build. We’re offering 2x included usage inside Cursor and Grok Build for the first week.
Training Grok 4.6
Grok 4.6 underwent a longer supplemental training run than Grok 4.5, with curated model-generated data for reasoning and advanced technical concepts, high-quality engineering data, and an improved optimizer and training recipe. This produced a stronger foundation for the SFT and RL stages that followed.
We then used Grok 4.5 to regenerate the SFT trajectories across reasoning efforts, agent harnesses, and domains such as STEM, software engineering, and knowledge work. We filtered out problematic traces with model-based checks. The resulting SFT checkpoint shows strong performance and improved behavior.
Grok 4.6 is trained on a wide range of agentic RL tasks, including knowledge work, general coding, and domain-specific environments for kernel optimization, web development, computer-aided design, and more.
Turning ambitious ideas into working projects
We tested Grok 4.6 on projects designed to stretch its range and ability to sustain work over many steps. We found the model is especially strong at turning a broad product idea into a working first version. It can research unfamiliar domains, structure the application, implement the core interactions, and continue refining the result through several rounds of feedback.
On longer trajectories, we also started to see more self-testing and verification, with the model checking its own work before moving on.
Grok 4.6 produces stronger first passes on visual and interactive projects than we typically saw with Grok 4.5. Given a concrete product idea, it is able to establish structure and visual language for an application in one pass. This has made it especially useful for projects where the fastest route to a good result was to begin with something substantial and then iterate in the loop.
Safety and capabilities
Grok 4.6's safeguards have been improved and calibrated in line with the model's capabilities.
Our safety stack is designed to maximize utility and security across legitimate use cases, allowing Grok 4.6 to be helpful and safe in domains such as vulnerability patching, accelerating the engineering design cycle, and augmenting AI research.
Our safeguard evaluation work reflects Grok 4.6’s expanded capabilities, with our widest-ever suite of pre-deployment testing for capabilities and safeguard calibration, as well as extensive post-deployment third-party testing.
