Muse Voice Transcribe (muse-voice-transcribe-1.0): Meta Superintelligence Labs' first real-time audio perception model, launched 2026-09-01; closed-source, API-only, $0.18/hour of audio ($3.00 per 1,000 minutes); 3.1% final-transcript WER on streaming (#1 on Artificial Analysis AA-WER Streaming, ahead of Cartesia Ink-2's 3.4%), 0.16s delay from end-of-speech to final transcript; one model does ASR, 20+ speaker diarization, and endpointing together, replacing what used to require three separate systems
Muse Spark 1.2: 1M context window, input $1.25 / output $4.25 per 1M tokens (same as 1.1), AA Intelligence Index 57, GDPval-AA v2 Elo jumps 260 points to 1631 (5th overall), paired with Meta's first code agent Muse Code for long-running multi-agent collaboration
Llama is Meta's open-source LLM family, with the largest enterprise deployment footprint and the most mature ecosystem. Llama 4 Scout (10M context) and Maverick (17B active / 400B total MoE) are the current open multimodal benchmarks, but Meta pivoted to closed-source Muse Spark in April 2026—Llama 4 is likely the last major open Llama, and its license is not truly open (Llama 4 Community License, separate license required above 700M MAU).
In August 2026, Meta Superintelligence Labs released Muse Code beta. Closed-source static binary, Muse Spark 1.2 model, parallel persistent sub-agents with worktree isolation. The biggest controversy is pricing: Standard at $1.25/$4.25 per M tokens, or Contributor at $0.10/$0.20 — 20x cheaper, but your code enters Meta's training pipeline.
Northeastern tested 17,260 Android apps and found zero activating the microphone. In May 2026 the FTC ruled that Cox Media Group — the company that claimed to be listening — collected no voice data at all and was reselling data-broker email lists, settling for $930,000. The real pipelines are off-site event feedback, lookalike spillover, contact-graph uploads, and location brokers.
