量子位 · wechat · 2026-09-21

• Alibaba's Qwen3.8-Omni-Flash scores 26% higher on average than Qwen3.5-Omni-Plus across 30 benchmarks including WildClawBench-MM, with audio beating Gemini 3.8 Flash.
• API pricing: 0.8 yuan/M input tokens, 2.7 yuan/M output; hourly audio input is >98% cheaper and audio-video input >93% cheaper than its predecessor—over 80% below discounted Gemini 3.8 Flash. A free 1M-context tier is open.
• Hands-on: paired with the OmniChatCut plugin (QwenImage, Wan, FFmpeg), it generated a decent MV from a self-written song, though setup took 1.5 hours; it also cleanly summarized a 45-minute Altman-Benioff interview with speaker IDs and timestamps.
• It recognizes 39 Chinese dialects, including fluent Cantonese conversation.
