## Chat Model ### Post-Training Data 360's proprietary general fine-tuning dataset consists of 500,000 samples. This dataset considers various skills and 360's vertical business data, with the following generation methods: 1. **Data Diversity**: Layered sampling based on 360's proprietary tagging system, considering domain, intent, difficulty, and length to ensure instruction diversity. 2. **Data Quality**: Using open-source data and proprietary preference-ordered data to train 360gpt-pro-rm (reward benchmark score of 92.59). This model is used for sample screening to filter out low-quality responses. 3. **Complex Instruction Evolution**: Optimizing complex instructions through evolutionary methods to enhance instruction-following capabilities. ### Training Methods 1. **Full Parameter Fine-Tuning** Based on the general post-training data, full parameter fine-tuning is performed, and the optimal checkpoint is selected as sft-base. 2. **LoRA Off-policy DPO** Using human-labeled preference pairs, LoRA fine-tuning is applied to the sft-base model, followed by LoRA DPO training. 3. **Iterative On-Policy DPO** The sft-base model samples multiple answers on training prompts, and 360gpt-pro-rm scores them. The highest and lowest scoring answers form each pair, and such pairs are used for DPO training. This on-policy DPO method is iteratively used to improve model performance. 4. **Model Merging** Automatic evaluations on 360's white-box evaluation set v4 revealed that different models excel in different skills. A model merging scheme was considered. Using the sft model as the base, interpolation with model v1 was performed, followed by extrapolation between the sft model and model v1 with an extrapolation coefficient of 0.2. This resulted in the final 360Zhicao2-7B-Chat-4k model. ### Model Performance We evaluated the 360Zhicao2-7B-Chat-4k model on several classic tasks. The IFEval (prompt strict) score was second only to GLM4-9B, making it the highest among open-source 7B models. It ranked third on MT-bench, slightly behind Qwen2.5-7B, and second among 7B models. It placed third on CF-Bench, and for PSR, it was second only to GLM4-9B. Detailed results are shown in the table below: | Model | MT-bench | IFEval(strict prompt) | CFBench(CSR,ISR,PSR) | | | |----------------------|----------|-----------------------|----------------------|------|------| | Qwen2.5-7B-Instruct | **8.07** | 0.556 | **0.81** | 0.46 | 0.57 | | Yi-9B-16k-Chat | 7.44 | 0.455 | 0.75 | 0.4 | 0.52 | | GLM4-9B-Chat | **8.08** | **0.634** | **0.82** | 0.48 | 0.61 | | InternLM2.5-7B-Chat | 7.39 | 0.540 | 0.78 | 0.4 | 0.54 | | 360Zhicao2-7B-Chat-4k| 7.86 | **0.577** | 0.8 | 0.44 | 0.57 | ### Long Context Fine-Tuning Similar to the method used during the open-sourcing of 360Zhinao1, we expanded the RoPE base to 1,000,000 and 50,000,000, sequentially concatenated SFT data of mixed long and short texts to 32k and 360k. By combining techniques like gradient checkpointing, ZeRO3 offload, and ring attention, we fine-tuned models to achieve 32k and 360k long context capabilities. These models ranked in the top tier across various 32k benchmarks. | Model | LooGLE-Long Dependency QA | Loong-Set 1 (32k) | LongBench-Chat (32k cutoff) | LEval-96 question subset | LEval-closed ended | |------------------------------|-----------------|-------------------|--------------------------|--------------------|------------------| | GLM4-9B-Chat | 0.36 | 55.24 | 6.60 | 0.49 | 63.96 | | InternLM2.5-7B-Chat | 0.39 | 42.76 | 5.70 | 0.44 | 61.64 | | 360Zhinao2-7B-Chat-32k | 0.33 | 39.37 | 5.44 | 0.44 | 60.48 | | 360Zhinao2-7B-Chat-360k | 0.34 | 32.16 | 5.08 | 0.38 | 53.00 | | Yi-1.5-9B-Chat | 0.25 | 32.77 | 4.70 | 0.37 | 56.22 |

# Model Inference ## Quantization We provide quantization schemes based on AutoGPTQ and release the Int4 quantization models. ## Deployment ### vLLM Installation We recommend using `vLLM==0.3.3`. If you are using **CUDA 12.1 and PyTorch 2.1**, you can install vLLM directly with: ```shell pip install vllm==0.3.3 ``` Otherwise, please refer to the official vLLM [Installation Instructions](https://docs.vllm.ai/en/latest/getting_started/installation.html). After installation, perform the following steps: 1. Copy `vllm/zhinao.py` into `vllm/model_executor/models` in your vllm installation directory (in python/conda env). 2. Copy `vllm/serving_chat.py` into `vllm/entrypoints/openai` in your vllm installation directory. 3. Then add a line in `vllm/model_executor/models/__init__.py` ```shell "ZhinaoForCausalLM": ("zhinao", "ZhinaoForCausalLM"), ``` ### vLLM Service Start Start the service: ```shell python -m vllm.entrypoints.openai.api_server \ --served-model-name 360Zhinao2-7B-Chat-4K \ --model qihoo360/360Zhinao2-7B-Chat-4K \ --trust-remote-code \ --tensor-parallel-size 1 \ --max-model-len 4096 \ --host 0.0.0.0 \ --port 8360 ``` Use curl to request the service: ```shell curl http://localhost:8360/v1/chat/completions \ -H "Content-Type: application/json" \ -d '{ "model": "360Zhinao2-7B-Chat-4K", "max_tokens": 200, "top_k": -1, "top_p": 0.8, "temperature": 1.0, "presence_penalty": 0.0, "frequency_penalty": 0.0, "messages": [ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "你好"} ], "stop": [ "", "<|im_end|>", "<|im_start|>" ] }' ``` Use python to request the service: ```python from openai import OpenAI openai_api_key = "EMPTY" openai_api_base = "http://localhost:8360/v1" client = OpenAI( api_key=openai_api_key, base_url=openai_api_base, ) chat_response = client.chat.completions.create( model="360Zhinao2-7B-Chat-4K", messages=[ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "你好"}, ], stop=[ "", "<|im_end|>", "<|im_start|>" ], presence_penalty=0.0, frequency_penalty=0.0 ) print("Chat response:", chat_response) ``` > If you need to enable repetition penalty, we recommend setting `presence_penalty` and `frequency_penalty` instead of `repetition_penalty`.
# Model Finetune ## Training data Training Data: `data/training_data_sample.json`. This example data has 10,000 rows sampled from [multiturn_chat_0.8M](https://huggingface.co/datasets/BelleGroup/multiturn_chat_0.8M) with converted format. Data Format: ```json [ { "id": 1, "conversations": [ { "from": "system", "value": "You are a helpful assistant." }, { "from": "user", "value": "您好啊" }, { "from": "assistant", "value": "你好！我今天能为您做些什么？有什么问题或需要帮助吗? 我在这里为您提供服务。" } ] } ] ``` ## Finetuning scripts ```shell set -x HOSTFILE=hostfile DS_CONFIG=./finetune/ds_config_zero2.json # PARAMS LR=5e-6 EPOCHS=3 MAX_LEN=4096 BATCH_SIZE=4 NUM_NODES=1 NUM_GPUS=8 MASTER_PORT=29500 IS_CONCAT=False # Whether to concatenate to maximum length (MAX_LEN) DATA_PATH="./data/training_data_sample.json" MODEL_PATH="qihoo360/360Zhinao2-7B-Base" OUTPUT_DIR="./outputs/" deepspeed --hostfile ${HOSTFILE} \ --master_port ${MASTER_PORT} \ --num_nodes ${NUM_NODES} \ --num_gpus ${NUM_GPUS} \ finetune.py \ --report_to "tensorboard" \ --data_path ${DATA_PATH} \ --model_name_or_path ${MODEL_PATH} \ --output_dir ${OUTPUT_DIR} \ --model_max_length ${MAX_LEN} \ --num_train_epochs ${EPOCHS} \ --per_device_train_batch_size ${BATCH_SIZE} \ --gradient_accumulation_steps 1 \ --save_strategy steps \ --save_steps 200 \ --learning_rate ${LR} \ --lr_scheduler_type cosine \ --adam_beta1 0.9 \ --adam_beta2 0.95 \ --adam_epsilon 1e-8 \ --max_grad_norm 1.0 \ --weight_decay 0.1 \ --warmup_ratio 0.01 \ --gradient_checkpointing True \ --bf16 True \ --tf32 True \ --deepspeed ${DS_CONFIG} \ --is_concat ${IS_CONCAT} \ --logging_steps 1 \ --log_on_each_node False ``` ```shell bash finetune/ds_finetune.sh ``` - Configuring `HOSTFILE` switches between single-machine and multi-machine training. - configuring `ds_config` switches between zero1, zero2 and zero3. - `fp16, bf16` could configure mixed precision training. bf16 is recommended to be consistent with the pretrained model. - `is_concat` configures whether the training data is concatenated or not.
