The Open Public Registry for Frontier AI Models & Research Checkpoints
ModelRegistry is a community-driven, machine-readable index tracking the state of foundational artificial intelligence. Rather than letting outdated models clutter developer workflows or burying flagship LLMs under niche audio drops, ModelRegistry maintains a clear dual-tier structure:
- Primary Foundation Flagships: The reigning general-purpose models developers actually use in production (e.g. Meta Muse Spark 1.3, OpenAI GPT-5.6 Sol, Anthropic Claude Fable 5.1, Google Gemini 3.8 Flash, DeepSeek V4-Pro).
- Latest Specialized Checkpoints: Newly dropped breakthroughs (e.g. Meta Muse Voice Transcribe, OpenAI Astra, Claude Opus 5, DeepSeek V4 Flash Vision Exp).
