NaiveAI Releases 309B Naive-N0.5-Flash Model With MIT License and 1 Million Token Context

NaiveAI has released Naive-N0.5-Flash, a 309-billion-parameter mixture-of-experts model with only 15.5 billion active parameters and a native 1 million token context window, under an MIT open-source license. The model, which eliminates full-attention layers entirely and instead pairs sliding-window attention with sparse-attention mechanisms, became available on September 27, 2026, on Hugging Face.
