Aitana-2B-S-IP-Instruct is an instruction-tuned generative language model from the Aitana family, developed by the GPLSI (Language and Information Systems Group) at the University of Alicante. Built on Aitana-2B-S-IP-Instruct, this model has been fine-tuned to follow instructions across Valencian, Spanish, and English, with a specialized focus on intellectual property domain tasks.
Aitana-2B-S-IP-Instruct is an instruction-tuned variant of Aitana-2B-S-IP-Instruct, fine-tuned on multilingual instruction data with emphasis on intellectual property applications.
Training Data
This model was instruction fine-tuned using the following data:
Instruction following in Valencian, Spanish, and English
Intellectual property domain applications
Chat and conversational applications requiring multilingual support
Text generation with task-specific prompting

The model was also evaluated using an LLM-as-judge approach across different task categories. The scores below represent the average rating (1-5 scale, 5 being best) and standard deviation for each task category, comparing against Salamandra-2B-Instruct.
