We’ve completed our first Meta Muse benchmarks.
Spark 1.3 holds the top spot for Muse. However, it still trailed GPT, Gemini and Claude Opus on single-host proof scores.

ALT Meta Muse Model Performance in SOC Investigations. Verdicts with accepted proof, Single Host Intrusion / Multi-Host Intrusion: Muse Spark 1.3 11/36 and 4/12; Muse Wonder 9/36 and 4/12; Muse Spark Open 1/36 and 1/12; GPT-6.1 Sol 25/36 and 5/12; GPT-6 Astra 25/36 and 5/12; Gemini 4 Argon 29/36 and 4/12; Claude Opus 5.5 12/36 and 5/12; Claude Sonnet 5.5 11/36 and 4/12. All High effort. One pass; preliminary.
Our first Gemini 4 Argon Benchmark and it performed incredibly well!

🤖 Made with AI
We tested 3 AI decision models on a DFIR task: finding other activity connected to a confirmed attack.
Cloudflare's Clef, Cloudflare's Clef Flash and Jev each ran 8 cases, 3 times.
Here's how they stacked up:

🔎 GPT-6 Astra retrieved sufficient evidence in 36/36 basic DFIR cases.
25/36 ended with a correct decision and accepted proof.
Finding the records doesn’t guarantee a supported conclusion.
Preliminary, one pass per case.

📊 Our first AI security benchmark results are live.
In 36 basic DFIR cases, Claude Opus 5.5 got 33 verdicts right. 12 also met our proof requirements.
Why we score the answer and its evidence separately:

🧭 18/18 verdicts. 12/18 next steps.
Jev 1.13's preliminary SOC results show why “right answer” and “right action” need separate scores.
Our new analysis covers six models and the limits of a six-case test:
