Qwen3.8-Flash
Qwen3.8 Flash is Alibaba’s cloud-only multimodal reasoning model with a one-million-token context window and pricing of $0.16 / $0.47 per million tokens. It processes text, image, and video with tool calling, accessible via Alibaba Cloud and OpenRouter. The open base Qwen3.8-Flash-Next is available, but the tested build is cloud-only. Architecture and parameter count are not disclosed, and data is routed through Chinese jurisdiction.

Sovereign Risk: MEDIUM Base weights are openly available (Qwen/Qwen3.8-Flash-Next, qwen-community-1.0, official NVFP4/GGUF/FP8 quants) — local deployment possible. The tested OpenRouter endpoint, however, is Alibaba’s production build (Qwen3.8-Flash, 1M context, built-in tools), whose exact post-training differences from Flash-Next have not been disclosed. Development/operations are subject to Chinese jurisdiction.

Key metrics – legend
Score
- Total Score
- Overall score derived from Routine and Reasoning scores. Basis for the fleet rank and tier assignment (Gold / Silver / Bronze / Standard).
- Routine
- Score for standard tasks: code generation, text transformation, structured outputs. Weighted by task complexity.
- Reasoning
- Score for analytical and logical tasks: multi-step problem solving, mathematical reasoning, structured argumentation.
- Rank
- Position in the fleet comparison, sorted by Total Score. Refers to the snapshot at the time of testing.
LLM Judge
- LLM Judge Ø
- Average quality rating by an independent judge model on a scale of 1–5.
- Coverage
- Share of tasks for which a judge rating is available. 100% means all responses were evaluated.
Latency & speed
- Avg. Task Duration
- Average time per task from the first to the last token of the response, measured across all benchmark tasks.
- Token Rate
- Output speed in tokens per second. Relevant for interactive applications and real-time streaming.
- P95 Latency
- 95th percentile of response times — shows outliers. Lower values mean fewer long wait times in edge cases.
Cost
- Cost per 1K
- API price per 1,000 output tokens in US dollars. Basis for cost calculation in production use.
- Benchmark Cost
- Total cost for the complete benchmark run of this model.
