Chart: Meta went 492 days without an open-weight release before Muse Spark Open

- A timeline chart by zorgresearch shows Meta's open-weight releases from LLaMA-7B (Feb 2023) through Llama 4 (Apr 2025), followed by a 492-day gap until Muse Glimmer (AA 17) and Muse Spark Open (AA 39, 816B total / 42B active).
- demianai recounts the two-year bet behind Nebius AI Studio: inference would be big and someone had to host the open models builders wanted. Llama 3.3 was the flagship — customers asked for Llama or Mistral, and an 8B-class model could stand next to GPT-4o and Claude 3.5 without a 405B rack.
- Then DeepSeek and Qwen arrived, the catalog crowded overnight, and open source stopped being a two-name, Western-only game. Release intervals shrank from 144d/275d to 60-120d, then the 492d drought, then two models just 66 days apart.
