We've updated the Artificial Analysis Coding Agent Index, replacing SWE-Bench Pro with Datacurve's DeepSWE benchmark - the swap lifts Codex with GPT-5.5 (xhigh) above Claude Code with Opus 4.8 (max), while the newly released Claude Fable 5 (max) in Claude Code debuts at the top DeepSWE, built by @datacurve, writes its tasks from scratch rather than adapting them from public GitHub issues or pull requests, so no model has seen the solutions during training. That matters because SWE-Bench Pro, the benchmark it replaces in our Coding Agent Index, had grown gameable, with some models recovering the fix from the repository's commit history instead of solving the task. The swap reorders the index: Codex with GPT-5.5 (xhigh) rises from 65 to 76, overtaking Claude Code with Opus 4.8 (max) at 73. Claude Code with Fable 5 (max), which enters directly on the refreshed index, leads at 77. SWE-Bench Pro had been flattering some combinations and penalizing others. More below.

WEEEEEEEEEEE

Opus 4.8 is now on DeepSWE. On the default high thinking effort, it scores 6% higher than Opus 4.7 xhigh, while also lowering average cost per task.

The new @datacurve site is insane

This is the first code bench that actually aligns with how it feels to use these models coding.

Worked on acquiring and processing these tasks! Hope this provides unique, and valuable insights on how to better evaluate models in a sea of benchmarks

Today we’re announcing we’ve raised $17.5 million in funding across a $15M Series A led by Chemistry and a $2.7M Seed to accelerate foundation model progress through providing frontier training data for LLMs. When we first started Datacurve, it came from a simple realization: foundation model progress is limited not just by compute, but by data quality and complexity. The right data unlocks new capabilities, especially in coding, where accuracy and reasoning matter most. We’re now proud to partner with the world’s leading foundation-model labs, providing them with high-quality, complex training data that helps push the boundaries of what AI can do. This is still just the start. Come build the future of technology with us in San Francisco: datacurve.ai/careers Huge thanks to our incredible team and investors who’ve believed in us since day one and beyond: @garrytan at @ycombinator, @1vnzh from @cohere , @Mark_Goldberg_ from @chemistry_fund, @TheDerrickLi from @AforeVC, @forwarddeploy, @SoheilK, and @shyamalanadkat.

think i need more degods

launched v1 of Profiles. get in discord and let us know what features to add next :)

DeGod Profiles V1 is live. Designed alongside with @budaz__ — excited to share what we’ve built for the community.

Profiles v1 is live. Designed by @We5lie & @budaz__ — animated by me. Massive props to @LeonardMainnet, @0x_chill & @thebasedbob for engineering magic. Grateful to help bring this to life for the community.

Topped it up to 50 DeGods Fuck it, we ball @DeGodsNFT

I actually dropped a y00ts coloring book on Amazon recently! Please help spread the word 🙏 a.co/d/axYbcJD

It has always been @DeGodsNFT.
