LongReward-glm4-9b-SFT is supervisedly fined-tuned from [glm-4-9b](https://huggingface.co/THUDM/glm-4-9b) using the `sft` split of [LongReward-10k](https://huggingface.co/datasets/THUDM/LongReward-45) dataset,  and supports a maximum context window of up to 64K tokens. 

Environment: Same environment requirement as [glm-4-9b-chat](https://huggingface.co/THUDM/glm-4-9b-chat) (`transforemrs>=4.43.0`).

A simple demo for deployment of the model:
```python
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

model_path = "NeoZ123/LongReward-glm4-9b-SFT"
tokenizer = AutoTokenizer.from_pretrained(model_path, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype=torch.bfloat16, trust_remote_code=True, device_map='auto')
context = '''
W. Russell Todd, 94, United States Army general (b. 1928). February 13. Tim Aymar, 59, heavy metal singer (Pharaoh) (b. 1963). Marshall \"Eddie\" Conway, 76, Black Panther Party leader (b. 1946). Roger Bonk, 78, football player (North Dakota Fighting Sioux, Winnipeg Blue Bombers) (b. 1944). Conrad Dobler, 72, football player (St. Louis Cardinals, New Orleans Saints, Buffalo Bills) (b. 1950). Brian DuBois, 55, baseball player (Detroit Tigers) (b. 1967). Robert Geddes, 99, architect, dean of the Princeton University School of Architecture (1965–1982) (b. 1923). Tom Luddy, 79, film producer (Barfly, The Secret Garden), co-founder of the Telluride Film Festival (b. 1943). David Singmaster, 84, mathematician (b. 1938).
'''
query = "What was Robert Geddes' profession?"
prompt = context + '\n\n' + query
response, _ = model.chat(tokenizer, prompt, temprature=1, max_new_tokens=1024)
print(response)
```

You can also deploy the model with [vllm](https://github.com/vllm-project/vllm) for faster inference:
```python
import torch
from vllm import LLM, SamplingParams

model_path = "NeoZ123/LongReward-glm4-9b-SFT"
model = LLM(
    model= model_path,
    dtype=torch.bfloat16,
    trust_remote_code=True,
    tensor_parallel_size=1,
    max_model_len=65536,
    gpu_memory_utilization=1,
)
tokenizer = model.get_tokenizer()
context = '''
W. Russell Todd, 94, United States Army general (b. 1928). February 13. Tim Aymar, 59, heavy metal singer (Pharaoh) (b. 1963). Marshall \"Eddie\" Conway, 76, Black Panther Party leader (b. 1946). Roger Bonk, 78, football player (North Dakota Fighting Sioux, Winnipeg Blue Bombers) (b. 1944). Conrad Dobler, 72, football player (St. Louis Cardinals, New Orleans Saints, Buffalo Bills) (b. 1950). Brian DuBois, 55, baseball player (Detroit Tigers) (b. 1967). Robert Geddes, 99, architect, dean of the Princeton University School of Architecture (1965–1982) (b. 1923).

'''
query = "What was Robert Geddes' profession?"
prompt = context + '\n\n' + query
inputs = tokenizer.build_chat_input(prompt, history=[], role='user')
eos_token_id = [tokenizer.eos_token_id, tokenizer.get_command("<|user|>"), tokenizer.get_command("<|observation|>")]
generation_params = SamplingParams(
    temperature=0.95,
    top_p=0.7,
    max_tokens=1024,
    stop_token_ids=eos_token_id,
)
input_ids = inputs.input_ids[0].tolist()
outputs = model.generate(sampling_params=generation_params, prompt_token_ids=[input_ids])
response = tokenizer.decode(outputs[0].outputs[0].token_ids[:-1])
print(response)
