SpaceXAI launches Grok 4.7, a longer-horizon coding and knowledge-work model
SpaceXAI released Grok 4.7 on September 21, a new frontier model built around longer task runs: a larger base model and a longer reinforcement-learning cycle on multi-hour task mixes, tuned to stay on hard coding and knowledge-work assignments and check its own output over long runs. It carries a 500k-token context window, takes text and image input, and offers four reasoning-effort levels — low, medium, high (default), and xhigh — so users can trade speed for depth.
The notable move is economic rather than architectural: pricing is held at Grok 4.6 levels, $2 per million input tokens and $6 per million output tokens below 200k prompt tokens ($4 input / $12 output above that threshold, with cached input discounted to $0.50). A Grok 4.7 Fast variant runs at twice the output speed for twice the price, but it is available only in Cursor and Grok Build — not on the public xAI API. Access is now open in Cursor, Grok Build (which offers free trial access), the Grok API, third-party coding harnesses, model routers, and cloud platforms.
SpaceXAI-reported benchmarks include 46.3% on CursorBench 4.0, 71.0% on DeepSWE v1.1, 64.0% on EEBench, 38.0% on Terminal-Bench 4.0, 19.6% on the Harvey Legal Agent Benchmark, and a score of 1,657 on AA Briefcase v1.1 — all first-party figures, not independently rerun. The company also says select cybersecurity partners are getting invite-only access to its red-team capabilities for defense research.
Why it matters
The competitive axis here is completed-task economics at a fixed price: SpaceXAI shipped a bigger, longer-horizon model without raising token rates, and Grok Build's free trial makes it the cheapest way this week to hand a long coding task to a frontier-class agent. For builders choosing between premium-priced APIs and this, the per-task cost math just shifted.
