Code for "AnyGPT: Unified Multimodal LLM with Discrete Sequence Modeling"
Stars: 730
AnyGPT is a unified multimodal language model that utilizes discrete representations for processing various modalities like speech, text, images, and music. It aligns the modalities for intermodal conversions and text processing. AnyInstruct dataset is constructed for generative models. The model proposes a generative training scheme using Next Token Prediction task for training on a Large Language Model (LLM). It aims to compress vast multimodal data on the internet into a single model for emerging capabilities. The tool supports tasks like text-to-image, image captioning, ASR, TTS, text-to-music, and music captioning.
README:
We introduce AnyGPT, an any-to-any multimodal language model that utilizes discrete representations for the unified processing of various modalities, including speech, text, images, and music. The base model aligns the four modalities, allowing for intermodal conversions between different modalities and text. Furthermore, we constructed the AnyInstruct dataset based on various generative models, which contains instructions for arbitrary modal interconversion. Trained on this dataset, our chat model can engage in free multimodal conversations, where multimodal data can be inserted at will.
AnyGPT proposes a generative training scheme that converts all modal data into a unified discrete representation, using the Next Token Prediction task for unified training on a Large Language Model (LLM). From the perspective of 'compression is intelligence': when the quality of the Tokenizer is high enough, and the perplexity (PPL) of the LLM is low enough, it is possible to compress the vast amount of multimodal data on the internet into the same model, thereby emerging capabilities not present in a pure text-based LLM. Demos are shown in project page.

Notes
For different tasks, we used different language model decoding strategies. The decoding configuration files for image, speech, and music generation are located in config/image_generate_config.json, config/speech_generate_config.json, and config/music_generate_config.json, respectively. The decoding configuration files for other modalities to text are in config/text_generate_config.json. You can directly modify or add parameters to change the decoding strategy.
Due to limitations in data and training resources, the model's generation may still be unstable. You can generate multiple times or try different decoding strategies.
The speech and music response will be saved to .wav files, and the image response will be saved to a jpg. The filename will be a concatenation of the prompt and the time. The paths to these files will be indicated in the response.

interleaved|{text_instruction}|{modality}|{image_path}|{voice_prompt}|{speech_instruction}|{music_path}Where text_instruction is the input text command, speech_instruction is the input voice command; only one needs to be specified.
image_path and music_path are the paths for the input image and music, respectively. voice_prompt is the specified tone of the model's response; if not specified, a random tone is used.
modality refers to the type of output modality, which can be chosen as speech, image, or music; otherwise, it is considered as text. This will only affect which decoding configuration file under the config directory is used by the model (this is because the model's training is limited, leading to different decoding strategies for different modalities). It can also decode token by token, modifying the decoding strategy to the corresponding modality when generating the start token of the modality.

We provide training data samples for reference. The organization of training formats includes pre-training data in data/pretrain and instruction data in data/instruction. For prompts of different tasks, refer to task_prompts, such as plain text dialogue, voice command text reply, text command voice reply, and special prompts for various tasks. You need to process multi-modal data into multi-round dialogue format according to the task template in advance. We use a voice conversation as an example in the command data, corresponding to the use of task_prompts in the "Speech-Instruction" and "Speech-Response":
[

"role": "user",
"message": "<sosp><🗣️1><🗣️1><🗣️1><eosp> Please acknowledge the user's vocal input, create a textual response"
