Suggestions for usage

Simple, concise prompts perform better
Avoid instructions, especially ones like "Respond with no if xyz is true" as it will tend to always respond with "no" irrespective of what is in the image
VQA Mode makes its responses a lot more concise. If you would like verbose answers, use the default setup with VQA mode set to False

Get Started

Option 1: Inference Using Web Demo.

Click here to enter CogVLM & CogAgent Web Demo。

If you need to use Agent and Grounding functions, please refer to Cookbook - Task Prompts

Option 2：Deploy CogVLM / CogAgent by yourself

We support two GUIs for model inference, CLI and web demo . If you want to use it in your python code, it is easy to modify the CLI scripts for your case.

First, we need to install the dependencies.

# CUDA >= 11.8
pip install -r requirements.txt
python -m spacy download en_core_web_sm

All code for inference is located under the basic_demo/ directory. Please switch to this directory first before proceeding with further operations.

Situation 2.1 CLI (SAT version)

Run CLI demo via:

# CogAgent
python cli_demo_sat.py --from_pretrained cogagent-chat --version chat --bf16  --stream_chat
python cli_demo_sat.py --from_pretrained cogagent-vqa --version chat_old --bf16  --stream_chat

# CogVLM
python cli_demo_sat.py --from_pretrained cogvlm-chat --version chat_old --bf16  --stream_chat
python cli_demo_sat.py --from_pretrained cogvlm-grounding-generalist --version base --bf16  --stream_chat

The program will automatically download the sat model and interact in the command line. You can generate replies by entering instructions and pressing enter. Enter clear to clear the conversation history and stop to stop the program.

We also support model parallel inference, which splits model to multiple (2/4/8) GPUs. --nproc-per-node=[n] in the following command controls the number of used GPUs.

torchrun --standalone --nnodes=1 --nproc-per-node=2 cli_demo_sat.py --from_pretrained cogagent-chat --version chat --bf16

If you want to manually download the weights, you can replace the path after --from_pretrained with the model path.

Our model supports SAT's 4-bit quantization and 8-bit quantization. You can change --bf16 to --fp16, or --fp16 --quant 4, or --fp16 --quant 8.

For example

python cli_demo_sat.py --from_pretrained cogagent-chat --fp16 --quant 8 --stream_chat
python cli_demo_sat.py --from_pretrained cogvlm-chat-v1.1 --fp16 --quant 4 --stream_chat
# In SAT version，--quant should be used with --fp16

The program provides the following hyperparameters to control the generation process:

usage: cli_demo_sat.py [-h] [--max_length MAX_LENGTH] [--top_p TOP_P] [--top_k TOP_K] [--temperature TEMPERATURE]

optional arguments:
-h, --help            show this help message and exit
--max_length MAX_LENGTH
                        max length of the total sequence
--top_p TOP_P         top p for nucleus sampling
--top_k TOP_K         top k for top k sampling
--temperature TEMPERATURE
                        temperature for sampling

Click here to view the correspondence between different models and the --version parameter.

Situation 2.2 CLI (Huggingface version)

Run CLI demo via:

# CogAgent
python cli_demo_hf.py --from_pretrained THUDM/cogagent-chat-hf --bf16
python cli_demo_hf.py --from_pretrained THUDM/cogagent-vqa-hf --bf16

# CogVLM
python cli_demo_hf.py --from_pretrained THUDM/cogvlm-chat-hf --bf16
python cli_demo_hf.py --from_pretrained THUDM/cogvlm-grounding-generalist --bf16

If you want to manually download the weights, you can replace the path after --from_pretrained with the model path.
You can change --bf16 to --fp16, or --quant 4. For example, our model supports Huggingface's 4-bit quantization:
```
python cli_demo_hf.py --from_pretrained THUDM/cogvlm-chat-hf --quant 4
```

Situation 2.3 Web Demo

We also offer a local web demo based on Gradio. First, install Gradio by running: pip install gradio. Then download and enter this repository and run web_demo.py. See the next section for detailed usage:

python web_demo.py --from_pretrained cogagent-chat --version chat --bf16
python web_demo.py --from_pretrained cogagent-vqa --version chat_old --bf16
python web_demo.py --from_pretrained cogvlm-chat-v1.1 --version chat_old --bf16
python web_demo.py --from_pretrained cogvlm-grounding-generalist --version base --bf16

The GUI of the web demo looks like:

Option 3：Finetuning CogAgent / CogVLM

You may want to use CogVLM in your own task, which needs a different output style or domain knowledge. All code for finetuning is located under the finetune_demo/ directory.

We here provide a finetuning example for Captcha Recognition using lora.

Start by downloading the Captcha Images dataset. Once downloaded, extract the contents of the ZIP file.
To create a train/validation/test split in the ratio of 80/5/15, execute the following:
```
python utils/split_dataset.py
```

Start the fine-tuning process with this command:

bash finetune_demo/finetune_(cogagent/cogvlm)_lora.sh

Merge the model to model_parallel_size=1: (replace the 4 below with your training MP_SIZE)

torchrun --standalone --nnodes=1 --nproc-per-node=4 utils/merge_model.py --version base --bf16 --from_pretrained ./checkpoints/merged_lora_(cogagent/cogvlm490/cogvlm224)

Evaluate the performance of your model.

bash finetune_demo/evaluate_(cogagent/cogvlm).sh

Option 4: OpenAI Vision format

We provide the same API examples as GPT-4V, which you can view in openai_demo.

First, start the node

python openai_demo/openai_api.py

Next, run the request example node, which is an example of a continuous dialogue

python openai_demo/openai_api_request.py

You will get output similar to the following

This image showcases a tranquil natural scene with a wooden pathway leading through a field of lush green grass. In the distance, there are trees and some scattered structures, possibly houses or small buildings. The sky is clear with a few scattered clouds, suggesting a bright and sunny day.

Hardware requirement

Model Inference:

For INT4 quantization: 1 * RTX 3090(24G) (CogAgent takes ~ 12.6GB, CogVLM takes ~ 11GB)

For FP16: 1 * A100(80G) or 2 * RTX 3090(24G)
Finetuning:

For FP16: 4 * A100(80G) [Recommend] or 8* RTX 3090(24G).

Model checkpoints

If you run the basic_demo/cli_demo*.py from the code repository, it will automatically download SAT or Hugging Face weights. Alternatively, you can choose to manually download the necessary weights.

Introduction to CogAgent

CogAgent is an open-source visual language model improved based on CogVLM. CogAgent-18B has 11 billion visual parameters and 7 billion language parameters

CogAgent-18B achieves state-of-the-art generalist performance on 9 classic cross-modal benchmarks, including VQAv2, OK-VQ, TextVQA, ST-VQA, ChartQA, infoVQA, DocVQA, MM-Vet, and POPE. It significantly surpasses existing models on GUI operation datasets such as AITW and Mind2Web.

In addition to all the features already present in CogVLM (visual multi-round dialogue, visual grounding), CogAgent:

Supports higher resolution visual input and dialogue question-answering. It supports ultra-high-resolution image inputs of 1120x1120.
Possesses the capabilities of a visual Agent, being able to return a plan, next action, and specific operations with coordinates for any given task on any GUI screenshot.
Enhanced GUI-related question-answering capabilities, allowing it to handle questions about any GUI screenshot, such as web pages, PC apps, mobile applications, etc.
Enhanced capabilities in OCR-related tasks through improved pre-training and fine-tuning.

GUI Agent Examples

Cookbook

Task Prompts

General Multi-Round Dialogue: Say whatever you want.
GUI Agent Task: Use the Agent template and replace <TASK> with the task instruction enclosed in double quotes. This query can make CogAgent infer Plan and Next Action. If adding (with grounding) at the end of the query, the model will return a formalized action representation with coordinates.

For example, to ask the model how to complete the task "Search for CogVLM" on a current GUI screenshot, follow these steps:

Randomly select a template from the Agent template. Here, we choose What steps do I need to take to <TASK>?.
Replace <TASK> with the task instruction enclosed in double quotes, for example, What steps do I need to take to "Search for CogVLM"? . Inputting this to the model yields:

Plan: 1. Type 'CogVLM' into the Google search bar. 2. Review the search results that appear. 3. Click on a relevant result to read more about CogVLM or access further resources.

Next Action: Move the cursor to the Google search bar, and type 'CogVLM' into it.

If adding (with grounding) at the end, i.e. changing the input to What steps do I need to take to "Search for CogVLM"?(with grounding), the output of CogAgent would be:

Plan: 1. Type 'CogVLM' into the Google search bar. 2. Review the search results that appear. 3. Click on a relevant result to read more about CogVLM or access further resources.

Next Action: Move the cursor to the Google search bar, and type 'CogVLM' into it. Grounded Operation:[combobox] Search -> TYPE: CogVLM at the box [[212,498,787,564]]

Tip: For GUI Agent tasks, it is recommended to conduct only single-round dialogues for each image for better results.

Visual Grounding. Three modes of grounding are supported:
- Image description with grounding coordinates (bounding box). Use any template from caption_with_box template as model input. For example:
Can you provide a description of the image and include the coordinates [[x0,y0,x1,y1]] for each mentioned object?
- Returning grounding coordinates (bounding box) based on the description of objects. Use any template from caption2box template, replacing <expr> with the object's description. For example:
Can you point out children in blue T-shirts in the image and provide the bounding boxes of their location?
- Providing a description based on bounding box coordinates. Use a template from box2caption template, replacing <objs> with the position coordinates. For example:
Tell me what you see within the designated area [[086,540,400,760]] in the picture.

Format of coordination: The bounding box coordinates in the model's input and output use the format [[x1, y1, x2, y2]], with the origin at the top left corner, the x-axis to the right, and the y-axis downward. (x1, y1) and (x2, y2) are the top-left and bottom-right corners, respectively, with values as relative coordinates multiplied by 1000 (prefixed with zeros to three digits).

Which --version to use

Due to differences in model functionalities, different model versions may have distinct --version specifications for the text processor, meaning the format of the prompts used varies.

FAQ

If you have trouble in accessing huggingface.co, you can add --local_tokenizer /path/to/vicuna-7b-v1.5 to load the tokenizer.
If you have trouble in automatically downloading model with 🔨SAT, try downloading from 🤖modelscope or 🤗huggingface or 💡wisemodel manually.
Download model using 🔨SAT, the model will be saved to the default location ~/.sat_models. Change the default location by setting the environment variable SAT_HOME. For example, if you want to save the model to /path/to/my/models, you can run export SAT_HOME=/path/to/my/models before running the python command.
