QVQ

QVQ is a visual reasoning model that supports visual input and chain-of-thought output. It shows stronger capabilities in mathematics, coding, visual analysis, creativity, and general tasks. Usage instructions

Qwen-VL

Qwen-VL is a text generation model that can understand and process images. The model performs OCR operations and provides further functionalities, such as summarizing and reasoning. For example, it can extract product attributes from photos, and solving problems from images. Usage instructions | API reference | Try online

Qwen-VL is billed based on the total number of input and output tokens.

Image token calculation rule: Every 28 × 28 pixels count as 1 token. Each image converts to at least 4 tokens. For more information, see Visual understanding.

Text generation - Qwen - open source

• In the model name, 'xxb' indicates the parameter scale. For example, 'qwen2-72b-instruct' has 72 billion parameters.

• Model Studio facilitates the use of open source Qwen models without the need for local deployment. Qwen3 and Qwen2.5 are most recommended among the open source models.

Qwen2.5

Qwen2.5 is the latest series of the Qwen LLM. For Qwen2.5, we have launched a series of base and instruct models with parameter sizes ranging from 7 billion to 72 billion. Qwen2.5 has made the following improvements over Qwen2:

• Qwen2.5 is pre-trained on our latest large-scale dataset containing 18 trillion tokens.

• Thanks to our expert models in specific fields, Qwen2.5 has significantly increased knowledge and greatly improved coding and maths capabilities.

• Qwen2.5 has shown significant improvements in following instructions, generating long texts (over 8K tokens), understanding structured data (such as tables), and generating structured outputs (especially JSON). It supports more diversified system prompts, enhancing its role-playing and conditional setting as a chatbot.

• Qwen2.5 supports over 29 languages, including Chinese, English, French, Spanish, Portuguese, German, Italian, Russian, Japanese, Korean, Vietnamese, Thai, Arabic, and more.
