Eubiota-Planner-8B: Specialized AI for Microbiome Discovery
Eubiota-Planner-8B is an 8-billion parameter causal language model, fine-tuned from Qwen3-8B by Stanford University. It is specifically designed as the central planning module for the Eubiota agentic AI framework, focusing on autonomous microbiome discovery.
Key Capabilities
- Agentic Planning: Orchestrates multi-agent reasoning and tool-grounded scientific exploration.
- Microbiome Research: Generates hypotheses about host-microbe interactions and designs experiments.
- Multi-Tool Coordination: Selects and sequences 18 domain-specific tools, including PubMed, KEGG databases, and MDIPID databases, for complex scientific queries.
- Advanced Training: Utilizes GRPO-MAS (Group Relative Policy Optimization for Multi-Agent Systems), a reinforcement learning approach for multi-agent coordination, enabling effective tool selection and sequencing.
Training and Evaluation
The model was trained on a diverse set of domain-specific datasets, including Microbio-Bench for microbiome reasoning, PubMedQA, MedQA-USMLE for medical-biology reasoning, DeepMath-103K for mathematical reasoning, and Natural Questions for agentic search.
It is evaluated on six benchmarks, covering both general biomedical competence (MedMCQA, WMDP-Bio) and specific microbiome mechanistic reasoning tasks (Drug-Microbe Impact, Microbe-Protein Mechanism, Protein Functional Comprehension, Protein-Gene Mapping).
Intended Use Cases
- Microbiome Hypothesis Generation: Formulating mechanistic hypotheses.
- Experimental Design: Planning scientific workflows for microbiome research.
- Scientific Query Resolution: Answering complex scientific questions by coordinating various domain-specific tools.
