TL;DR
- Grok 4.7 is $2 per 1M input and $6 per 1M output, with a 500,000-token context window. Output at $6 is 70% cheaper than GPT-5.6 sol's $20 and 76% cheaper than Claude Opus 5's $25. Cached input reads at $0.50, 75% below the fresh-input rate.
- The long-context step is real, and it starts at 200K. At or above 200,000 prompt tokens, xAI bills the whole request at $4 input / $12 output — 2× on both sides. The 500,000-token window is not a flat-rate window, and the calculator now models the step.
- The window nearly doubled and the old model is retired. Grok 4 sat at 256,000 tokens; Grok 4.7 sits at 500,000, and Grok 4 is now delisted with the note "Replaced by Grok 4.7". This is an upgrade, not a choice.
- We have two verified scores for it — the thinnest card in this series. Terminal-Bench 4.0 at 38.0 and DeepSWE v1.1 at 71.0, which the source lists as "DeepSWE". No reasoning, knowledge or math score on file.
What shipped
- A new Grok generation at lower prices. Grok 4.7: $2 per 1M input, $6 per 1M output, cached input $0.50, 500,000-token context window, active. xAI's pricing table dates the model to 2026-09-21.
- Grok 4 is retired but not forgotten. It was $3 / $15 and is now marked delisted with the note "Replaced by Grok 4.7"; the row stays so that old price searches still resolve.
- The window nearly doubled. 256,000 tokens on Grok 4, 500,000 on Grok 4.7. On a long-document workload that is roughly half as many chunks to design around, at a lower per-token price — until the prompt crosses 200K, where the long-context rate applies.
- A cached-input rate and a long-context tier both exist. xAI's table prints short-context
$2.00 / $0.50 / $6.00and a long-context$4.00 / $12.00input-output pair (the cached read doubles too) for the same model. Our earlier page said neither was on file; both are, and both are now in the registry.
What it costs
- Output is where this model is priced to compete. $6 per 1M output against GPT-5.6 sol's $20 is 70% less, and against Claude Opus 5's $25 is 76% less. Input at $2 is half of GPT-5.6 sol's $4 and 60% below Claude Opus 5's $5.
- The cut against its own predecessor is deeper on output. Grok 4 was $3 / $15; Grok 4.7 is $2 / $6 — 33% less on input and 60% less on output. The generation change is not a price-neutral refactor.
- Cache-heavy traffic gets a third number, not a rounding error. Cached input at $0.50 is 25% of the $2 fresh rate — a 75% discount. For an agent loop that re-reads the same system prompt or tool schema every turn, that is the line that decides the bill.
- The 500,000-token window is not flat-rate. Once a prompt reaches 200,000 tokens, the whole request is billed at $4 input / $12 output, and the cached read doubles too. A 250,000-token prompt costs twice what the headline rate suggests; the calculator applies the step, so price the tier explicitly rather than multiplying the headline by token count.
- The price shape is 3:1 from input to output. $2 in, $6 out. Agentic loops, long generations and any workload that produces rather than consumes tokens pay the higher number, so the 60% output cut is where the saving actually lands.
How it scores
- Two benchmarks. That is the whole card. Terminal-Bench 4.0 at 38.0 and DeepSWE v1.1 at 71.0 — the second one is published under the name "DeepSWE" in the source we cite.
- Read the two rows as adjacent, not as a ranking. The comparison rows on the table cover different benchmarks, so the common ground is thin: one agentic-terminal column and one repository-engineering column. We do not average two scores into a headline number.
- What the table can tell you: on the two columns every model reports, Grok 4.7 sits in the same band as the flagship rows it is compared against, at a fraction of the price. That is a statement about those two benchmarks, not about the model.
- What it cannot tell you: anything about reasoning, knowledge or mathematics, because no such score is on file. If your product depends on a reasoning benchmark, this table is not going to settle it.
Should you switch?
- If you were on Grok 4: switch. The old model is delisted, the new one is 33% cheaper on input and 60% cheaper on output, and the window went from 256,000 to 500,000 tokens. There is no scenario where holding the old SKU is the right call.
- If you are on GPT-5.6 sol or Claude Opus 5 and your bill is output-driven, the arithmetic favours a trial: at $6 output you are paying 70% to 76% less for the tokens you generate. Start with the workloads that produce the most — long generations, agentic loops, batch processing — and measure quality on real traffic.
- If your workload is input-heavy — RAG over long documents, say — check the 200K threshold before you budget. The 500,000-token window is the reason to look, but a prompt above 200K is billed at $4 input, not $2. Fewer chunks still helps; the saving is smaller than the headline suggests.
- If you need reasoning or knowledge capability, do not switch on this table. We have no comparable scores for Grok 4.7 on those, and the models in the same rows do.
- Before you commit: a 2–2.5× price difference is a good reason to A/B. A missing benchmark is a reason to keep measuring. Run both at once for a week and let your own evals decide.
