Image understanding on a text-first base

Image input is layered on top of DeepSeek V4 Flash without giving up its text performance, so the same model works for plain chat and for tasks that require reading an image.

Thinking mode by default

Reasoning tokens are generated automatically before the final answer, which helps on multi-step or ambiguous requests without extra configuration.

1M-token context window

Long documents, transcripts, or multi-turn conversations can be passed in a single request without chunking.

Visual question answering

Ask questions about screenshots, diagrams, or photos alongside regular text instructions in the same request.

Use cases

This model is documented for visual understanding workflows, including describing pictures, reading text from screenshots, and analyzing charts.

It is also documented for multimodal agent workflows, where visual understanding is combined with tools to support practical agent-based tasks.

It is documented for UI analysis and screenshot-based tasks, such as identifying interface elements and reasoning from visual evidence.

It is documented for document extraction from images, including invoices, receipts, delivery notes, and insurance forms.
