Detailed Methodology of DeepSeek Janus Professional 7B
1. Architectural Overview
Janus-Professional adheres to an autoregressive framework with a decoupled visible encoding method:
- Multimodal Understanding: Options are flattened from a 2D grid right into a 1D sequence. An adaptor then maps these options into the enter area of the LLM.
- Visible Era: The VQ tokenizer converts photos into discrete IDs. These IDs are flattened and mapped into the LLM’s enter area utilizing a era adaptor.
- Unified Processing: The multimodal characteristic sequences are concatenated and processed by the LLM, with separate prediction heads for textual content and picture outputs.
1. Understanding (Processing Pictures to Generate Textual content)
This module permits the mannequin to analyze and describe photos primarily based on an enter question.

- Extracts essential visible options from the picture (similar to objects, colours, and spatial relationships).
- Converts the uncooked picture right into a compressed illustration that the transformer can perceive.
- Textual content Tokenizer
- If a language instruction is offered (e.g., “What’s on this picture?”), it’s tokenized right into a numerical format.
- Auto-Regressive Transformer
- Processes each picture options and textual content tokens to generate a textual content response.
- Textual content De-Tokenizer
- Converts the mannequin’s numerical output into human-readable textual content.
Instance:
Enter: A picture of a cat sitting on a desk + “Describe the picture.”
Output: “A small white cat is sitting on a wood desk.”
2. Picture Era (Processing Textual content to Generate Pictures)
This module permits the mannequin to create new photos from textual descriptions.
How It Works:
- Enter: Language Instruction
- A consumer offers a textual content immediate describing the specified picture (e.g., “A futuristic metropolis at evening.”).
- Textual content Tokenizer
- The textual content enter is tokenized into numerical format.
- Auto-Regressive Transformer
- Predicts the picture illustration token by token.
- Gen. Encoder (Era Encoder)
- Converts the anticipated picture illustration right into a structured format.
- Picture Decoder
- Generates the ultimate picture primarily based on the encoded illustration.
Instance:
Enter: “A dragon flying over a fortress at sundown.”
Output: AI-generated picture of a dragon hovering above a medieval fortress at sundown.
