🌟Overview

This is the OceanGPT (沧渊) project, which aims to build LLMs for ocean science tasks.

• ❗Disclaimer: This project is purely an academic exploration rather than a product(本项目仅为学术探索并非产品应用). Please be aware that due to the inherent limitations of large language models, there may be issues such as hallucinations.

Inference

Inference by HuggingFace

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

path = 'YOUR-MODEL-PATH'

model = AutoModelForCausalLM.from_pretrained(
    path,

    device_map="auto"
)

🌻Acknowledgement

OceanGPT (沧渊) is trained based on the open-sourced large language models including Qwen, MiniCPM, LLaMA. Thanks for their great contributions!

Limitations

• The model may have hallucination issues.

• We did not optimize the identity and the model may generate identity information similar to that of Qwen/MiniCPM/LLaMA/GPT series models.

• The model's output is influenced by prompt tokens, which may result in inconsistent results across multiple attempts.

• The model requires the inclusion of specific simulator code instructions for training in order to possess simulated embodied intelligence capabilities (the simulator is subject to copyright restrictions and cannot be made available for now), and its current capabilities are quite limited.
