Grok 4.7 matches frontier coding performance at a fraction of the price
xAI's Grok 4.7 is a new flagship model for coding and knowledge work, trained with longer reinforcement learning on harder, multi-hour tasks. It scores 46.3% on CursorBench 4.0 and 71.0% on DeepSWE v1.1, outperforming Grok 4.6 while costing $2 per million input tokens and $6 per million output tokens—far below GPT-5.6 Sol and Fable 5.1. It also ships with a new safeguard stack that blocks 96.7% of risky dual-use prompts.
It shows the highest safety on HackerBench v0.3, our benchmark for risky and malicious cyber tasks, allowing only 3.3% of risky dual-use prompts through while rarely blocking legitimate security work.

Apparently Grok 4.7 has 40% more weights than Grok 4.6, but the price ($6 output token, $2 input) is the same.
Given that the decrease in their margin and the fact they delayed the release of Grok 4.7 almost two weeks past the original date, XAI must not have been happy with the results for 4.7. And XAI also waited the day before Opus 5.5 is rumored to launch. I imagine Opus 5.5 will blow Grok 4.7 out of the water benchmark wise.
However, I have become skeptical of benchmarks. Grok 4.5 solved some issues setting up a buildroot system that Fable 5 couldn't do. I find the post cursor groks are phenomenal at frontend web development, though Claude is much better at backend ruby.
My favorite part of the new Groks has been how they speak in plain english. I simply cannot stand Claudish. Or even GPT, which doesn't have Claude's ticks but definitely likes to handwave explaining technical concepts. Still, nothing beats Claude 3.5 and 4 with explaining since it seems all models have regressed. I wonder if Grok 4.7 will also regress with English because of all the RL.

Initial impressions, Grok 4.6 for me just didn't really hack it for any usecase I tried. I seem to have a floor for my usecaseses (coding and a bunch of agentic workflows) and Sol/Opus are above some kind of intelligence floor.
4.7 is definitely slower & more expensive. It feels kind of like they really had it burn tokens to claw up the benchmarks. But it's not super clear to me whether it's above the line or not. A part of that is that it is so slow that i haven't been making fast progress today with benchmarking it.
Overall, it it gets above my intelligence line its a good release...but you can read the tea leaves and tell the Grok team thinks this was a miss.

Nice to see this release cadence increasing and some continued improvement in quality. I am guessing these models are basically still outcomes of the cursor team integrating with the massive amount of compute they now own: I’d imagine we will see significant step up improvements with grok 5 later this year as the team gets more experienced and confident with larger training deployments. Here’s hoping for another competitive frontier model!

It's definitely gotten better at image->html workflows. Here's a test comparing Astra (currently SOTA at this) vs Grok 4.7:
Designs: https://image.non.io/78795662-8bfc-4e14-8d72-3738392aa6b3.we...
Astra's build: https://html.non.io/annui/
Grok's build: https://html.non.io/Annui-grok/
Additional prompt instructions: "Add scrolling clouds behind the statues. Dynamically light the statues based on mouse position. Use diffui to generate the normal maps/depth maps/roughness maps of the objects, and to separate out the assets on to different layers."
Overall I find these models are getting good at following image as a source of instructions, but their refinement of the output varies heavily between the models. Astra's final output feels more polished, has better visual contrast, and the animations between the pages are smoother. Grok also chose to light all of the background elements, which imo overcooks it a bit.
Still though, for the price it's a great starting point.

https://tools.simonwillison.net/markdown-svg-renderer?url=ht... - default reasoning level.
Here's reasoning level high: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...
For some reason reasoning effort low and medium used similar numbers of tokens, and xhigh used less than high. I think I need to try without OpenRouter in the middle.
UPDATE: I tried again with the xAI API directly: https://tools.simonwillison.net/markdown-svg-renderer?url=ht... - not a great deal of difference between reasoning levels, and this time xhigh and low used the same number of reasoning tokens for some reason.
For comparison here's a fresh run against Grok 4.6: https://tools.simonwillison.net/markdown-svg-renderer?url=ht...

Not even close to astra. Astra is something else. It is expensive, but uses way fewer tokens do my tasks.
xAI missed its chance, Ball is on Anthropic's court.

I've been using 4.6 for some one-off game mods/utilities and it has done very well. "I have a very niche keyboard (Moonlander) and I play this very niche space sim, make me a SVG keyboard cheatsheet for it". Told me to grab keymap.c for the keyboard and inputmap.xml for the game's key bindings, churned for a while, then spit out a pretty good first attempt, along with the python script used to generate it. Spent another hour of back and forth to refine the script, and now it generates great diagrams that will adapt as my keyboard firmware and game bindings evolve: https://files.catbox.moe/x0u76x.svg
Excited to try 4.7. I hope they fixed the "it's not X, it's Y" that showed up in 4.6.

Grok it's really expensive. I'm getting really amazing results using DeepSeek 4.1 Flash for fraction of the price.

Looks like they have still problems with caching. Prize is double the other providers for cache hits... which is most of what I do. :/

Why are they comparing grok 4.7 xhigh to grok 4.6 high?
Unless they produce the same token output on the face of it, it looks like they're trying to cover for 4.7 not having good model perf?
