How popular is Grok compared to other companies models for SWE tasks? I almost never hear it talked about against OpenAI's or Anthropic's products

If they were a frontier lab, you'd know.

It seems to be extremely economical - 4x better reasoning efficiency compared to Opus while being priced at $2/$6. For comparison, GPT 5.4 is $2.5/$15, GPT 5.5/5.6 are $5/$30, Opus 4.8 is $5/$25, Fable is $10/$50. And by benchmarks (unless they gamed them), seems to be at around Opus 4.7 level, which is what Elon mentioned in https://x.com/elonmusk/status/2074911038286295049 . I guess the Cursor data was very useful.

The comparison may be better against GPT 5.6 Terra (instead of Sol), which is $2.5/$15.

We don't yet know Terra's results for DeepSWE/TerminalBench though.

Announcement from Cursor, whose team also trained the model: https://cursor.com/blog/grok-4-5.

Notably:

> Grok 4.5 and Composer 2.5 are two different model weight classes, and we're excited to support both sizes and weights. Composer 2.5 will remain offered, and we will release new models of this size going forward.

Of the 3 models I tried, Grok did the best at making an iOS app I wanted for personal use (a bike computer with specific qualities). (Claude just gave up and did an HTML/CSS implementation but I insisted on native SwiftUI+Metal.) Grok definitely fumbles sometimes, but I have been surprised what it CAN intuit versus me having to micromanage it. (I am not an iOS developer, so getting something specific that I needed in…

Was this in Claude Code for Claude? Did you use a weaker model like Haiku? Claude should absolutely not be as bad as you said.

Not available for Europeans yet. :(

I think it should be available through Cursor?

EDIT: Tested myself, it's actually NOT available from EU. But with a Swiss VPN it works :)

Now if they could have an "equivalent" to Claude's $100 plan with similar compute limits. I have the $40 a month version of Grok and I get a max of like 8 hours of "non-stop" Grok Build coding, per month.

I do a lot of native iOS development using Opus 4.8 (and I used 4.7/4.6 before this). I have a very hard time with this comment, were you using Opus or something else?

You can very roughly proxy popularity of close-sourced models through OpenRouter token throughput. Grok has an order of magnitude less OpenRouter usage than Claude, GPT, even Gemini.
