InternLM has open-sourced a 7 billion parameter base model and a chat model tailored for practical scenarios. The model has the following characteristics:

  • It leverages trillions of high-quality tokens for training to establish a powerful knowledge base.
  • It supports an 8k context window length, enabling longer input sequences and stronger reasoning capabilities.
  • It provides a versatile toolset for users to flexibly build their own workflows.

Additionally, a lightweight training framework is offered to support model pre-training without the need for extensive dependencies. With a single codebase, it supports pre-training on large-scale clusters with thousands of GPUs, and fine-tuning on a single GPU while achieving remarkable performance optimizations. InternLM achieves nearly 90% acceleration efficiency during training on 1024 GPUs.


Performance Evaluation

We conducted a comprehensive evaluation of InternLM using the open-source evaluation tool OpenCompass. The evaluation covered five dimensions of capabilities: disciplinary competence, language competence, knowledge competence, inference competence, and comprehension competence. Here are some of the evaluation results, and you can visit the OpenCompass leaderboard for more evaluation results.

  • The evaluation data may have numerical differences due to the version iteration of OpenCompass, so please refer to the latest evaluation results of OpenCompass.

Model Zoo

InternLM 7B and InternLM 7B Chat, trained using InternLM, have been open-sourced. We provide two formats of model weights for use. In addition to loading the models using the Transformers format, you can also load the weights directly using InternLM for further pre-training or human preference alignment training.

Model InternLM Format Weight Download Link Transformers Format Weight Download Link
InternLM 7B Open in OpenXLab 🤗internlm/intern-7b
InternLM Chat 7B Open in OpenXLab 🤗internlm/intern-chat-7b
InternLM Chat 7B 8k Open in OpenXLab 🤗internlm/intern-chat-7b-8k

Limitations: Although we have made efforts to ensure the safety of the model during the training process and to encourage the model to generate text that complies with ethical and legal requirements, the model may still produce unexpected outputs due to its size and probabilistic generation paradigm. For example, the generated responses may contain biases, discrimination, or other harmful content. Please do not propagate such content. We are not responsible for any consequences resulting from the dissemination of harmful information.

Import from Transformers

To load the InternLM 7B Chat model using Transformers, use the following code:

>>> from transformers import AutoTokenizer, AutoModelForCausalLM
>>> tokenizer = AutoTokenizer.from_pretrained("internlm/internlm-chat-7b", trust_remote_code=True)
>>> model = AutoModelForCausalLM.from_pretrained("internlm/internlm-chat-7b", torch_dtype=torch.float16, trust_remote_code=True).cuda()
>>> model = model.eval()
>>> response, history =, "hello", history=[])
>>> print(response)
Hello! How can I help you today?
>>> response, history =, "please provide three suggestions about time management", history=history)
>>> print(response)
Sure, here are three tips for effective time management:

1. Prioritize tasks based on importance and urgency: Make a list of all your tasks and categorize them into "important and urgent," "important but not urgent," and "not important but urgent." Focus on completing the tasks in the first category before moving on to the others.
2. Use a calendar or planner: Write down deadlines and appointments in a calendar or planner so you don't forget them. This will also help you schedule your time more effectively and avoid overbooking yourself.
3. Minimize distractions: Try to eliminate any potential distractions when working on important tasks. Turn off notifications on your phone, close unnecessary tabs on your computer, and find a quiet place to work if possible.

Remember, good time management skills take practice and patience. Start with small steps and gradually incorporate these habits into your daily routine.


You can interact with the InternLM Chat 7B model through a frontend interface by running the following code:

pip install streamlit==1.24.0
pip install transformers==4.30.2
streamlit run

The effect is as follows



We use LMDeploy to complete the one-click deployment of InternLM.

  1. First, install LMDeploy:
  python3 -m pip install lmdeploy
  1. Use the following command for quick deployment:
  python3 -m lmdeploy.serve.turbomind.deploy InternLM-7B /path/to/internlm-7b/model hf
  1. After exporting the model, you can start a server and have a conversation with the deployed model using the following command:
  python3 -m lmdeploy.serve.client {server_ip_addresss}:33337

LMDeploy provides a complete workflow for deploying InternLM. Please refer to the deployment tutorial for more details on deploying InternLM.

Fine-tuning & Training

Convert to Transformers Format

The model trained by InternLM can be easily converted to HuggingFace Transformers format, which is convenient for seamless docking with various open source projects in the community. With the help of tools/, the weights saved during training can be converted into transformers format with one command

python --src_folder origin_ckpt/ --tgt_folder hf_ckpt/ --tokenizer tokenizes/tokenizer.model

After conversion, it can be loaded as transformers by the following code

>>> from transformers import AutoTokenizer, AutoModel
>>> model = AutoModel.from_pretrained("hf_ckpt/", trust_remote_code=True).cuda()

Training Performance

InternLM deeply integrates Flash-Attention, Apex and other high-performance model operators to improve training efficiency. By building the Hybrid Zero technique, it achieves efficient overlap of computation and communication, significantly reducing cross-node communication traffic during training. InternLM supports expanding the 7B model from 8 GPUs to 1024 GPUs, with an acceleration efficiency of up to 90% at the thousand-GPU scale, a training throughput of over 180 TFLOPS, and an average of over 3600 tokens per GPU per second. The following table shows InternLM's scalability test data at different configurations:

GPU Number 8 16 32 64 128 256 512 1024
TGS 4078 3939 3919 3944 3928 3920 3835 3625
TFLOPS 193 191 188 188 187 185 186 184

TGS represents the average number of tokens processed per GPU per second. For more performance test data, please refer to the Training Performance document for further details.
