**Notes:**
The release of InternLM2.5 series contains 1.8B, 7B, and 20B versions. 7B models are efficient for research and application and 20B models are more powerful and can support more complex scenarios. The relation of these models are shown as follows.
1. **InternLM2.5**: Foundation models pre-trained on large-scale corpus. InternLM2.5 models are recommended for consideration in most applications.
2. **InternLM2.5-Chat**: The Chat model that undergoes supervised fine-tuning (SFT) and reinforcement learning from human feedback (RLHF), based on the InternLM2.5 model. InternLM2.5-Chat is optimized for instruction following, chat experience, and function call, which is recommended for downstream applications.
3. **InternLM2.5-Chat-1M**: InternLM2.5-Chat-1M supports 1M long-context with compatible performance as InternLM2.5-Chat.
**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.
**Supplements:** `HF` refers to the format used by HuggingFace in [transformers](https://github.com/huggingface/transformers), whereas `Origin` denotes the format adopted by the InternLM team in [InternEvo](https://github.com/InternLM/InternEvo).
### InternLM2-Reward
InternLM2-Reward is a series of reward models, trained on 2.4 million preference samples, available in 1.8B, 7B, and 20B sizes. These model were applied to the PPO training process of our chat models. See [model cards](./model_cards/internlm2_reward.md) for more details.

## Usages
InternLM supports a diverse range of well-known upstream and downstream projects, such as LLaMA-Factory, vLLM, llama.cpp, and more. This support enables a broad spectrum of users to utilize the InternLM series models more efficiently and conveniently. Tutorials for selected ecosystem projects are available [here](./ecosystem/README.md) for your convenience.
In the following chapters, we will focus on the usages with [Transformers](#import-from-transformers), [ModelScope](#import-from-modelscope), and [Web demos](#dialogue).
The chat models adopt [chatml format](./chat/chat_format.md) to support both chat and agent applications.
To ensure a better usage effect, please make sure that the installed transformers library version meets the following requirements before performing inference with [Transformers](#import-from-transformers) or [ModelScope](#import-from-modelscope):
```
transformers >= 4.38
```
### Import from Transformers
To load the InternLM2.5-7B-Chat model using Transformers, use the following code:
```python
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
tokenizer = AutoTokenizer.from_pretrained("internlm/internlm2_5-7b-chat", trust_remote_code=True)
# Set `torch_dtype=torch.float16` to load model in float16, otherwise it will be loaded as float32 and might cause OOM Error.
model = AutoModelForCausalLM.from_pretrained("internlm/internlm2_5-7b-chat", device_map="auto", trust_remote_code=True, torch_dtype=torch.float16)
# (Optional) If on low resource devices, you can load model in 4-bit or 8-bit to further save GPU memory via bitsandbytes.
# InternLM 7B in 4bit will cost nearly 8GB GPU memory.
# pip install -U bitsandbytes
# 8-bit: model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", trust_remote_code=True, load_in_8bit=True)
# 4-bit: model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", trust_remote_code=True, load_in_4bit=True)
model = model.eval()
response, history = model.chat(tokenizer, "hello", history=[])
print(response)
# Output: Hello? How can I help you today?
response, history = model.chat(tokenizer, "please provide three suggestions about time management", history=history)
print(response)
```
### Import from ModelScope
To load the InternLM2.5-7B-Chat model using ModelScope, use the following code:
```python
import torch
from modelscope import snapshot_download, AutoTokenizer, AutoModelForCausalLM
model_dir = snapshot_download('Shanghai_AI_Laboratory/internlm2_5-7b-chat')
tokenizer = AutoTokenizer.from_pretrained(model_dir, device_map="auto", trust_remote_code=True)
# Set `torch_dtype=torch.float16` to load model in float16, otherwise it will be loaded as float32 and might cause OOM Error.
model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", trust_remote_code=True, torch_dtype=torch.float16)
# (Optional) If on low resource devices, you can load model in 4-bit or 8-bit to further save GPU memory via bitsandbytes.
# InternLM 7B in 4bit will cost nearly 8GB GPU memory.
# pip install -U bitsandbytes
# 8-bit: model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", trust_remote_code=True, load_in_8bit=True)
# 4-bit: model = AutoModelForCausalLM.from_pretrained(model_dir, device_map="auto", trust_remote_code=True, load_in_4bit=True)
model = model.eval()
response, history = model.chat(tokenizer, "hello", history=[])
print(response)
response, history = model.chat(tokenizer, "please provide three suggestions about time management", history=history)
print(response)
```
### Dialogue
You can interact with the InternLM Chat 7B model through a frontend interface by running the following code:
```bash
pip install streamlit
pip install transformers>=4.38
streamlit run ./chat/web_demo.py
```
## Deployment by LMDeploy
We use [LMDeploy](https://github.com/InternLM/LMDeploy) for fast deployment of InternLM.
### Inference
With only 4 lines of codes, you can perform [internlm2_5-7b-chat](https://huggingface.co/internlm/internlm2_5-7b-chat) inference after `pip install lmdeploy`.
```python
from lmdeploy import pipeline
pipe = pipeline("internlm/internlm2_5-7b-chat")
response = pipe(["Hi, pls intro yourself", "Shanghai is"])
print(response)
```
To reduce the memory footprint, we offers 4-bit quantized model [internlm2_5-7b-chat-4bit](https://huggingface.co/internlm/internlm2_5-7b-chat-4bit), with which the inference can be conducted as follows:
```python
from lmdeploy import pipeline
pipe = pipeline("internlm/internlm2_5-7b-chat-4bit")
response = pipe(["Hi, pls intro yourself", "Shanghai is"])
print(response)
```
Moreover, you can independently activate the 8bit/4bit KV cache feature:
```python
from lmdeploy import pipeline, TurbomindEngineConfig
pipe = pipeline("internlm/internlm2_5-7b-chat-4bit",
backend_config=TurbomindEngineConfig(quant_policy=8))
response = pipe(["Hi, pls intro yourself", "Shanghai is"])
print(response)
```
Please refer to the [guidance](./chat/lmdeploy.md) for more usages about model deployment. For additional deployment tutorials, feel free to explore [here](https://github.com/InternLM/LMDeploy).
### 1M-long-context Inference
By enabling the Dynamic NTK feature of LMDeploy, you can acquire the long-context inference power.
Note: 1M context length requires 4xA100-80G.
```python
from lmdeploy import pipeline, GenerationConfig, TurbomindEngineConfig
backend_config = TurbomindEngineConfig(
rope_scaling_factor=2.5,
session_len=1048576, # 1M context length
max_batch_size=1,
cache_max_entry_count=0.7,
tp=4) # 4xA100-80G.
pipe = pipeline('internlm/internlm2_5-7b-chat-1m', backend_config=backend_config)
prompt = 'Use a long prompt to replace this sentence'
response = pipe(prompt)
print(response)
```
## Agent
InternLM2.5-Chat models have excellent tool utilization capabilities and can work with function calls in a zero-shot manner. It also supports to conduct analysis by collecting information from more than 100 web pages. See more examples in [agent section](./agent/).
## Fine-tuning
Please refer to [finetune docs](./finetune/) for fine-tuning with InternLM.
**Note:** We have migrated the whole training functionality in this project to [InternEvo](https://github.com/InternLM/InternEvo) for easier user experience, which provides efficient pre-training and fine-tuning infra for training InternLM.
## Evaluation
We utilize [OpenCompass](https://github.com/open-compass/opencompass) for model evaluation. In InternLM2.5, we primarily focus on standard objective evaluation, long-context evaluation (needle in a haystack), data contamination assessment, agent evaluation, and subjective evaluation.
### Objective Evaluation
To evaluate the InternLM model, please follow the guidelines in the [OpenCompass tutorial](https://opencompass.readthedocs.io/en/latest/get_started/installation.html). Typically, we use `ppl` for multiple-choice questions on the **Base** model and `gen` for all questions on the **Chat** model.
### Long-Context Evaluation (Needle in a Haystack)
For the `Needle in a Haystack` evaluation, refer to the tutorial provided in the [documentation](https://github.com/open-compass/opencompass/blob/main/docs/en/advanced_guides/needleinahaystack_eval.md). Feel free to try it out.
### Data Contamination Assessment
To learn more about data contamination assessment, please check the [contamination eval](https://opencompass.readthedocs.io/en/latest/advanced_guides/contamination_eval.html).
### Agent Evaluation
- To evaluate tool utilization, please refer to [T-Eval](https://github.com/open-compass/T-Eval).
- For code interpreter evaluation, use the [Math Agent Evaluation](agent/README.md) provided in the repository.
### Subjective Evaluation
- Please follow the [tutorial](https://opencompass.readthedocs.io/en/latest/advanced_guides/subjective_evaluation.html) for subjective evaluation.
