Qwen3.8 Omni Flash pricing

On OpenRouter, Qwen3.8 Omni Flash costs $0.15 per million input tokens and $0.47 per million output tokens. Counting three tokens read for every token written, its average price is $0.23 per million, more expensive than 23 % of paid models (3.3 times cheaper than the median of $0.76).

Features, privacy and local use

• It supports tool calling, so it can drive an AI agent, call APIs or MCP servers.
• It can answer in an enforced JSON format (structured outputs).
• It is a reasoning model: it "thinks" before answering, which helps on hard tasks but uses more output tokens.

Its weights are not published: it can only be used through the Alibaba (Qwen) API or a broker such as OpenRouter, which means sending your data off your machines.
