Your AI and this story

  • GPT-6 Astra193 days after its cutoff
  • Claude Opus 5.5132 days after its cutoff
  • Gemini 4 Hydrogen223 days after its cutoff
  • Grok 4.7162 days after its cutoff

None of these four assistants can know about it. The closest, Claude Opus 5.5, stops 132 days before it.

Key facts

  • Price: $0.10 input / $0.50 output per 1M tokens up to 200K-token prompts ($0.004 cached input); $0.30 / $1.50 above 200K
  • Up to 1M input tokens; text, image and audio input; six reasoning levels (minimal to max)
  • Meta: ‘Muse Wonder plans, Muse Ember handles the volume’; claims it beats Claude Haiku and GPT-6 Luna on the AA index per cost
  • Artificial Analysis Intelligence Index about 34 (xhigh) and 36 (max), roughly $0.12-0.14 per index task (read from AA’s chart by Simon Willison)
  • Simon Willison: same short-prompt price as GPT-6 Luna and Claude Haiku 5.5; its pelican SVGs comparable to Muse Wonder’s at about 1/40 the price

What happened

Meta added a low-cost tier below Muse Spark and Muse Wonder, aimed at the many cheap calls an agent system makes. The model id is muse-ember-1.0. TechCrunch did not report open weights.

Why it matters

It puts Meta in the cheap “workhorse” tier against GPT-6 Luna, Claude Haiku 5.5 and Chinese flash models, where most agent tokens are spent.
