Qwen3.5 Omni Plus API

alibaba/qwen3.5-omni-plus
The Plus variant is the flagship of the Qwen3.5 Omni family, sitting above Flash (optimized for speed) and Light (optimized for edge deployment). It's an instruct model, meaning it's fine-tuned for direct use rather than raw pretraining, and it supports a 256,000-token context window, enough to hold an entire book, a feature-length film's worth of captions, or over ten hours of continuous audio.
