Qwen3 30B A3BQwen/Qwen3-30B-A3B

A Mixture-of-Experts model that activates only 3.3B of its 30.5B parameters per forward pass. Offers dual thinking modes: a detailed step-by-step reasoning mode for complex problems and a faster non-thinking mode for simpler queries. Despite its small active parameter count, it outperforms QwQ-32B that has 10 times more activated parameters.

Qwen3 32Bqwen/qwen3-32b

Qwen3-32B is a dense 32.8B parameter causal language model from the Qwen3 series, optimized for both complex reasoning and efficient dialogue. It supports seamless switching between a "thinking" mode for tasks like math, coding, and logical inference, and a "non-thinking" mode for faster, general-purpose conversation. The model demonstrates strong performance in instruction-following, agent tool use, creative writing, and multilingual tasks across 100+ languages and dialects. It natively handles 32K token contexts and can extend to 131K tokens using YaRN-based scaling.
