Context 500k on the catalog, narrower than the 1M Claude / GPT-5.6 windows.

Ships across four xAI surfaces: the API, Grok Build, Cursor, and Grok Bot. Grok Bot never discloses its own default model and offers no picker, so a Bot run is not a Grok 4.6 run you can prove.

Should I use this for coding agents

Use Grok 4.6 when you already pay xAI or want Continuum’s hosted Grok. DeepSWE official: 67% ±2% at xhigh, $5.50 per task, 71k out, 87 steps. Tight CI.

When not to use it

Trust this before you buy

  • Official DeepSWE row is xhigh, not a silent default. xAI docs default effort is high. If you run it at low, do not expect 67%.
  • Sibling: Grok 4.5 has its own card. It left the Continuum hosted lineup on 17 Aug 2026. 500k context is smaller than the 1M Claude / GPT-5.6 windows.
  • Closed weights. No official GGUF. xAI embedded pricing lists batchDiscountPercent 0. Do not invent a batch discount.
  • Long-context surcharge is 2× at 200,000 tokens on the xAI table (and OpenRouter override ≥200k $4 / $12). That is not the $2 / $6 list.

Plus is $25/mo with $25 weekly hosted usage. The Mac app stays free with your own keys. Get Plus is not Download for Mac.

Weights

xAI does not publish Grok 4.6 weights. No HF button.

  • xAI models docs HTML (embedded JSON, fetched 19 Aug 2026): prompt 20000 / completion 60000 / cached 5000 at unit 1e-10 USD/token → $2 / $6 / $0.50 per million. Long-context 2× at 200,000 tokens. batchDiscountPercent 0. Efforts low / medium / high / xhigh, default high.
  • OpenRouter catalog 19 Aug 2026: $2 / $6, cache read $0.50 /M, web search $0.005 per call. Override ≥200k: $4 / $12, cache $1 /M. Official list and catalog match on the base pair.

What you can open

Lab card and OpenRouter listing only. No Hugging Face Files button, because there is no official repo to point at.

Fetched OpenRouter catalog on 2026-08-19. hugging_face_id was empty.

Economics

DeepSWE official: $5.50 per task at xhigh (71k out, 87 steps). That is the hero economics number.

Official xAI + OpenRouter, 19 Aug 2026: $2 / $6 per million, cache read $0.50 /M. Catalog web search $0.005 per call. ≥200k override $4 / $12. Batch discount printed as 0.

Artificial Analysis footnote, 19 Aug 2026, Grok 4.6 high: $2 / $6, about $0.84 per AA task. The AA tile is Intelligence Index 61. AA did not publish a DeepSWE-style CI or step count we will copy onto the chip.

FAQ

Why does the lab blog disagree with DeepSWE or Scale?

Lab posts pick a harness, an effort, a split, and sometimes a private eval set. DeepSWE publishes the official mini-swe-agent row with cost, tokens, and steps. Scale SWE-bench Pro only counts when the public shared-harness board has a row we can fetch. A higher lab number is usually a different test, not a better one.
