ClimateGPT-13B

ClimateGPT is a family of AI models designed to synthesize interdisciplinary research on climate change. ClimateGPT-13B is a 13 billion parameter transformer decoder model that was adapted from Llama-2 to the domain of climate science using continuous pre-training on a collection of 4.2B tokens from curated climate documents. The model is further instruction fine-tuned on a dataset of instruction-completion pairs manually collected by AppTek in cooperation with climate scientists. ClimateGPT-7B outperforms Llama-2-70B Chat on our climate-specific benchmarks. The model is designed to be used together with retrieval augmentation to extend the knowledge, and increase the factuality of the model and with cascaded machine translation to increase the language coverage.

• Paper: arXiv:2401.09646
• Website: eci.io

Uses

• This model is intended to be directly used as a question answering model that is specialized in the climate domain.
• The model is aimed at providing useful feedback for decision makers, scientists and journalists involved in climate discussions.
• The model can also be used as a starting point for interested developers for further fine-tuning.
• The model is NOT intended to be a general-purpose chatbot (although it has chat capabilities).
• For the full system including cascaded MT, RAG, etc., we recommend the user to go to our demo website: eci.io
• Despite the efforts from the development team to eliminate them, as every other chat-capable LLMs, this model may generate biased, offensive or inaccurate responses.

Downstream Use

ClimateGPT-13B is an instruction-tuned model that can be directly used for climate-specific question-answering applications. It was trained to perform well with retrieval augmentation and supports up to 5 references in context.

The model was trained using ChatML so the following format should be followed when prompting, including the <|im_start|>, <|im_end|> tags, system, user, context and assistant identifiers and [[0]], [[1]]] etc. tokens to indicate references.

"""
<|im_start|>system
{system_message}<|im_end|>
<|im_start|>user
{prompt}<|im_end|>
<|im_start|>context
[[0]] "{reference1_title}", {reference1_year}
{reference1_text}
[[1]] "{reference2_title}", {reference2_year}
{reference2_text}
[...]<|im_end|>
<|im_start|>assistant
"""

Training

• For the Llama2 training data, we refer the user to https://huggingface.co/meta-llama/Llama-2-13b-hf.
• For continued pre-training, 4.2B climate-specific tokens (tokenized by the Llama tokenizer) are used.
• For instruction fine-tuning, about 272K instruction-completion pairs (both in the climate domain but also general domain) are used.
