Benchmarks

BenchmarkSettingScoreReported byMeasuredVerifiedSource
GDPval-AA v2.1 Elo, higher is better 'Qwen3.8 2.4T A95B'; effort not shown; Stirrup agent harness 1,607 Elo Third party 2026-10-25 2026-10-25 GDPval-AA v2.1 Leaderboard (Artificial Analysis)
GDPval-AA v2.1 caveats:

Elo is a relative rating: values change as models are added and the scale is re-anchored, so always store the date a rating was read. For example, Anthropic's launch page gives 1846 for Claude Opus 5.5, while the leaderboard on 2026-10-12 shows 1866 (Max, Default Fallback). Earlier versions (Google cites "GDPVal-AA v2") are not comparable. Judging is done by an LLM, not by human experts. Anthropic models are listed with "Default Fallback", meaning refused steps are routed to a fallback model. AA-Briefcase and GDP.pdf are separate evaluations.

One row per result, without rank numbers: each result was measured under its own setting (effort level, harness, tools, test version), as stated by the source, and scores compare only within the same setting. Self-reported results come from the provider and have not been reproduced independently.

About Qwen3.8-2.4T-A95B

Qwen3.8-2.4T-A95B is the open-weights release of the Qwen3.8 flagship, using a sparse MoE architecture with 2.4 trillion total and about 95 billion activated parameters. It accepts text only and always reasons before answering; thinking cannot be disabled. The weights are published on Hugging Face under the custom Qwen3.8-Max License, which requires a separate license for Model-as-a-Service or AI work-assistant businesses whose revenue exceeds US$50 million over any 12-month period. Model Studio hosts it with a 1M-token context window, function calling, structured output and web search.

Strengths and weaknesses

Strengths

  • Open weights of a 2.4T-parameter MoE model (about 95B activated)
  • Hosted version: 1,000,000-token context window and up to 131,072 output tokens
  • Function calling, structured output, web search and context caching on Model Studio

Weaknesses

  • Text-only input (no image or video), unlike the hosted qwen3.8-max
  • Thinking cannot be disabled; maximum chain-of-thought length is 131,072 tokens versus 262,144 for qwen3.8-max
  • Custom license with additional conditions for large commercial users
