Alibaba: qwen3-8b API
The core dense model of the Qwen3 series, released by Alibaba Cloud on April 29, 2025. As the successor to Qwen2.5-7B, Qwen3-8B features 8.2 billion parameters and was pre-trained on a massive 36 trillion (36T) token multilingual dataset. Its most significant breakthrough is being the first under-10B model to support native Dual-Mode (Thinking/Non-Thinking) switching, delivering logical depth in math (AIME 2025) and code refactoring comparable to previous 70B-class models. It stands as one of the most powerful 8B-scale reasoning models in the global open-source community.
