Question 1

When will Muse Glimmer / Llama 5 Preview be released?

Accepted Answer

Based on Meta GenAI's 2026 release interval trend (92d -> 55d -> 43d), ModelRumors.ai projects Muse Glimmer / Llama 5 Preview to release in the window of Nov 19 – Nov 26, 2026 (15–22d away), compared to a naive flat-mean estimate of Dec 17, 2026 (Flat 63d Mean).

Question 2

Should I adopt Muse Spark Open & Llama 4.2 now or wait for Muse Glimmer / Llama 5 Preview?

Accepted Answer

Current Buyer's Verdict: MID-CYCLE · 57% OF TREND (57% of trend-adjusted cycle elapsed). Meta cut its release interval more than in half across 2026 (92d → 55d → 43d). While a flat 63-day average points to mid-December, damped slope extrapolation places Muse Glimmer / Llama 5 Preview right before Thanksgiving (Nov 19–26).
