You expected Llama-at-the-frontier. This is a small open agent.

Meta shipping small open models again after going closed with Spark. Useful on a desk, not a leaderboard.

  • AA Index. The single number most people mean by “how smart.” It is a blend, so a specialist can lose here and still win the job you care about.
  • GPQA. A clean test of hard reasoning. PhD experts sit around 65%. It says little about writing, tools, or taste.
  • Term.. Closest public proxy for coding agents that live in a terminal. A high index score with a weak terminal score is a warning.
  • Arena. Captures taste and usefulness that unit tests miss. Sample size varies by model, so treat gaps under ~100 Elo as noise.

Meta · Menlo Park. Muse is closed and powers Meta AI across Facebook, Instagram, and WhatsApp. Llama 4 still ships for local work. Glimmer is the small Apache agent.

Compiled 2026-08-28 from public Artificial Analysis, LMSYS-style arena, and first-party price sheets. Scores move. Recheck before you spend.

A two-point gap on the intelligence index is noise for most work. Cost per finished task is the number that shows up on the invoice.
