Qwen3.8-Max is Alibaba's latest frontier reasoning model. It's the first open-weight model in the Qwen3-Max series, accepts multimodal input, has a 1M token context window, and scores in the top 10 across 185 models on Artificial Analysis' Intelligence Index. Qwen3.8-Max is available now on Baseten Dedicated Inference.
What's new in Qwen3.8-Max
Qwen3.8-Max represents a significant leap over its predecessor, Qwen3.7-Max (released May 2026). The Artificial Analysis Intelligence Index has climbed from 47 to 58. Notably, this is the first model in the Qwen3-Max series to release with open weights, under the Qwen 3.8-Max license.
Here's how the Qwen3-Max series has evolved since it was first released in September 2025.
Features and benchmark performance
Qwen3.8-Max is a Mixture-of-Experts model with 2.4 trillion total parameters and 95B active parameters per token. Here are a few of its other key features:
Configurable reasoning level
Multimodal input
1M token context window
Function calling and structured outputs
Qwen3.8-Max scores 58 on the Artificial Analysis Intelligence Index (i.e., general intelligence), ranking #9 across all 185 benchmarked models. Qwen3.8-Max also ranks in the top 10% across these key quality benchmarks:
Ideal use cases
Knowledge work and research: Qwen3.8-Max excels at reasoning across large volumes of professional and scientific literature. With its 1M context window and top performance on GDPval-AA v2, AA-LCR, and GPQA Diamond, it provides reliable, high-level reasoning across extensive document sets.
Business process automation: Beyond standard question-and-answer tasks, Qwen3.8-Max’s function calling and structured outputs features enable it to execute business workflows utilizing enterprise applications. Strong scores on AutomationBench-AA, APEX-Agents-AA, and τ³‑Banking validate its ability to complete multi-step, cross-application tasks reliably.
Scientific and technical problem-solving: Qwen3.8-Max handles technical challenges, from writing executable Python code to solving graduate-level physics problems. Its proficiency is validated by high marks on the SciCode, CritPt, and GPQA Diamond benchmarks.
Agentic AI assistants: Create agents that handle varied inputs and multi-step tasks. With multimodal capabilities, configurable reasoning, and high scores on IFBench and MMMU-Pro, it follows intricate instructions across text and visual media with high precision.
