Geo-Expert: Towards Expert-Level Geological Reasoning via Parameter-Efficient Fine-Tuning
Researchers have developed Geo-Expert, a series of large language models specifically fine-tuned for geological reasoning. These models utilize parameter-efficient fine-tuning techniques like LoRA on base models such as Qwen3 and Gemma-3. Evaluations on a new benchmark, Geo-Eval, show that even an 8B parameter Geo-Expert model can surpass larger generalist models and GPT-4o on geological tasks, with a 32B variant nearing frontier model performance.
