Qwen3 VL Plus

qwenqwen/qwen3-vl-plus

Qwen3 vision-language — text + image input, text output, 256K context.

qwen3-vl-plus is the vision-language model of the Qwen3 generation. It accepts text and image content in the same OpenAI-compatible `messages` array and produces text answers — suitable for document understanding, chart reading, UI screenshot analysis, OCR-light extraction, and visual Q&A.

Images can be passed as HTTP URLs or base64 data URIs. The model's 256K context lets you bundle many images plus their textual instructions in a single call. TheRouter routes between bailian-cn and bailian-sg per request based on cost.

Text + image input
Mixed-modal `messages` content with `image_url` parts — OpenAI-format compatible.
256K context
Bundle many images and their prompts in a single call. Good fit for multi-page document VQA.
OCR-light extraction
Strong at reading text inside images — charts, screenshots, scanned forms — without a dedicated OCR pipeline.
Dual-region routing
Selector picks bailian-cn or bailian-sg per request based on cost.
When to use
Document VQA, chart and screenshot understanding, light OCR, UI-element extraction, and any workload that mixes text instructions with image content.
When not to use
Pure text reasoning (use qwen-plus / qwen3-max), text-to-image generation (use wan/wan2.2-t2i-*), or audio / video understanding — qwen3-vl-plus does not output images and does not consume audio.
Pricing: $0.30 input / $2.00 output per MTok. TheRouter routes to the cheaper of bailian-cn / bailian-sg per request. Image content is billed by the tokenised image size per Bailian's schedule.
