InternLM
Introduction
InternLM2 has open-sourced a 7 billion parameter base model and a chat model tailored for practical scenarios. The model has the following characteristics:
-
200K Context window: Nearly perfect at finding needles in the haystack with 200K-long context, with leading performance on long-context tasks like LongBench and L-Eval. Try it with
LMDeploy for 200K-context inference.
-
Outstanding comprehensive performance: Significantly better than the last generation in all dimensions, especially in reasoning, math, code, chat experience, instruction following, and creative writing, with leading performance among open-source models in similar sizes. In some evaluations, InternLM2-Chat-20B may match or even surpass ChatGPT (GPT-3.5).
-
Code interpreter & Data analysis: With code interpreter, InternLM2-Chat-20B obtains compatible performance with GPT-4 on GSM8K and MATH. InternLM2-Chat also provides data analysis capability.
-
Stronger tool use: Based on better tool utilization-related capabilities in instruction following, tool selection and reflection, InternLM2 can support more kinds of agents and multi-step tool calling for complex tasks. See
examples.

- The evaluation results were obtained from OpenCompass (some data marked with *, which means come from the original papers), and evaluation configuration can be found in the configuration files provided by OpenCompass.
- The evaluation data may have numerical differences due to the version iteration of OpenCompass, so please refer to the latest evaluation results of OpenCompass.
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 InternLM2 7B Chat model using Transformers, use the following code:
1import torch
2from transformers import AutoTokenizer, AutoModelForCausalLM
3tokenizer = AutoTokenizer.from_pretrained("internlm/internlm2-chat-7b", trust_remote_code=True)
4# Set `torch_dtype=torch.float16` to load model in float16, otherwise it will be loaded as float32 and cause OOM Error.
5model = AutoModelForCausalLM.from_pretrained("internlm/internlm2-chat-7b", torch_dtype=torch.float16, trust_remote_code=True).cuda()
6model = model.eval()
7response, history = model.chat(tokenizer, "hello", history=[])
8print(response)
9# Hello! How can I help you today?
10response, history = model.chat(tokenizer, "please provide three suggestions about time management", history=history)
11print(response)
The responses can be streamed using stream_chat:
1import torch
2from transformers import AutoModelForCausalLM, AutoTokenizer
3
4model_path = "internlm/internlm2-chat-7b"
5model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype=torch.float16, trust_remote_code=True).cuda()
6tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)
7
8model = model.eval()
9length = 0
10for response, history in model.stream_chat(tokenizer, "Hello", history=[]):
11 print(response[length:], flush=True, end="")
12 length = len(response)

局限性： 尽管在训练过程中我们非常注重模型的安全性，尽力促使模型输出符合伦理和法律要求的文本，但受限于模型大小以及概率生成范式，模型可能会产生各种不符合预期的输出，例如回复内容包含偏见、歧视等有害内容，请勿传播这些内容。由于传播不良信息导致的任何后果，本项目不承担责任。
通过 Transformers 加载
通过以下的代码加载 InternLM2 7B Chat 模型
1import torch
2from transformers import AutoTokenizer, AutoModelForCausalLM
3tokenizer = AutoTokenizer.from_pretrained("internlm/internlm2-chat-7b", trust_remote_code=True)
4# `torch_dtype=torch.float16` 可以令模型以 float16 精度加载，否则 transformers 会将模型加载为 float32，导致显存不足
5model = AutoModelForCausalLM.from_pretrained("internlm/internlm2-chat-7b", torch_dtype=torch.float16, trust_remote_code=True).cuda()
6model = model.eval()
7response, history = model.chat(tokenizer, "你好", history=[])
8print(response)
9# 你好！有什么我可以帮助你的吗？
10response, history = model.chat(tokenizer, "请提供三个管理时间的建议。", history=history)
11print(response)
如果想进行流式生成，则可以使用 stream_chat 接口：
1import torch
2from transformers import AutoModelForCausalLM, AutoTokenizer
