xAI released Grok 4.7 on its API for coding, agentic tasks and knowledge work, with a 500,000-token context window, text and image inputs, and adjustable reasoning levels. A context window that large lets the model hold the equivalent of a small book, or an entire codebase, in view at once, which matters for tasks that must reason across a lot of material.
Pricing is tiered by how much text is fed in, a common pattern as vendors compete on cost as much as capability.
What it means: very large context windows make it practical to ask a model to work over whole documents, contracts or code repositories without splitting them into pieces. For a business, that removes a fiddly limitation and widens the range of jobs an AI can take on in one pass.
