Source Summary

**Grok 4.6** is available in Cursor, Grok Build, the SpaceXAI API, and partner platforms. Cursor positions it for long-running coding and knowledge work, reporting more self-testing and stronger first passes on interactive and visual projects than Grok 4.5.

Practical Implication

Builders should trial it on multi-step implementation, research, and UI prototyping, then compare task completion and verification behavior against their current model. Pricing starts at **$2/M input tokens** and **$6/M output tokens**.

The benchmark discussion supplies few raw scores; the main comparison says it matches GPT-5.6 Sol on a nine-benchmark composite. A fast variant costs **2x**, and Cursor’s qualitative project findings are not independent evaluations.

This advances Grok’s long-running coding and knowledge-work case from 4.5 with claimed improvements in self-testing and interactive or visual first passes. The GPT-5.6 Sol composite supplies a comparison target, but sparse raw scores and Cursor’s non-independent observations leave workload trials as the decision basis, especially when weighing standard versus 2x-priced fast service.

Introducing Grok 4.5Grok 4.6 is presented as improving 4.5’s first-pass and self-testing behavior, while 4.5’s training-contamination issue remains a warning against relying on CursorBench comparisons alone.GPT 5.6 Sol, Luna, and Terra now available on AI GatewayGPT-5.6 Sol is the stated peer on the nine-benchmark composite and therefore the most direct candidate for representative task comparisons, despite the absence of detailed component scores.The Base Model Is Dead — Varun Singh, Arcee AIThe training-data argument reinforces evaluating Grok 4.6 on intended agent workloads rather than inferring capability from model branding or a composite benchmark.Introducing Claude Sonnet 5Sonnet 5 provides another similarly priced coding-oriented option, but its tokenizer change means token counts and effective task costs must be measured rather than compared from headline per-token prices alone.
