About

Qwen3.8-2.4T-A95B (Qwen/Qwen3.8-2.4T-A95B) is the flagship sparse Mixture-of-Experts model of Alibaba's Qwen3.8 generation - 2.4T total parameters with 95B activated per token - released August 8, 2026 under the Qwen3.8-Max License. Its 92-layer hybrid stack repeats 23x (3x (Gated DeltaNet -> MoE) + 1x (Gated Attention -> MoE)): 69 linear-attention layers (Gated DeltaNet, 128 V / 16 QK heads, head dim 128) and 23 full-attention layers (Gated Attention, 64 Q / 4 KV heads, head dim 256, RoPE dim 64), with 512 experts (10 routed + 1 shared per token, expert intermediate dim 2048), hidden size 8192, 248K vocabulary, Multi-Token Prediction (MTP) trained with multiple steps, and a 262,144-token native context extensible to 1,010,000 tokens.

Qwen3.8 delivers comprehensive improvements across coding, professional work, research and long-horizon agentic tasks; stronger autonomous planning and handling of environment feedback for reliable end-to-end agent execution; broader compatibility with popular harnesses and development tools; and flexible thinking control - reasoning depth tunable via reasoning_effort with reasoning context from historical messages retained via preserve_thinking.

Training Pipeline

  1. 1
    pretraining

    Pre-training

    Pre-training stage: Causal Language Model trained on large-scale multilingual corpus with Multi-Token Prediction (MTP). 2.4T total parameters, 95B activated parameters, MoE architecture with 512 experts (10 routed + 1 shared).

  2. 2
    sft

    Post-training (SFT + RL)

    Post-training stage: The model is a post-trained version with reasoning capabilities. Features reasoning_effort control (xhigh/medium/low) and preserve_thinking for retaining reasoning context across messages. Thinking mode is always on and cannot be disabled.
