Hey I am CosmoGemma 👋 I can answer cosmology questions from astroph.CO research articles.

This is a Gemma_2b_en fine-tuned on QA pairs (3.5k) generated from Cosmology and Nongalactic Astrophysics articles (arXiv astro-ph.CO) 
from 2018-2022 and tested on QA pairs (1k) generated from 2023 articles, scoring over 75% accuracy.


To generate an answer for a given question using this model, please use:

```
import keras
import keras_nlp

gemma_lm = keras_nlp.models.CausalLM.from_preset("hf://sultan-hassan/CosmoGemma_2b_en")
template = "Instruction:\n{instruction}\n\nResponse:\n{response}"

Question = "write your question here"

prompt = template.format(
  instruction=Question,                                                                   
  response="",
  )
out = gemma_lm.generate(prompt, max_length=1024)
ind = out.index('Response') + len('Response')+2
print ("Question:", Question)
print ("Answer:", out[ind:])
```
