ZOOOO-BetaCell-Expert-8B-v0.6.1

1. Overview

ZOOOO-BetaCell-Expert-8B-v0.6.1 is a research-stage mechanistic reasoning assistant for pancreatic β-cell biology developed by Os Lab within the ZOOOO framework.

The model is intended to help researchers and advanced students reason about β-cell function using causal structure, intervention logic, and explicit boundary conditions, rather than treating domain text as a surface-level terminology task. Typical questions involve stimulus–secretion coupling, cellular stress and failure modes, and how to interpret experimental observations without over-claiming mechanism.

The design target is a style of reasoning that:

• distinguishes causation vs correlation
• states assumptions and boundary conditions before asserting mechanisms
• prefers structural/constraint-first explanations over pathway listing
• terminates once the causal question is resolved

This model is not a general conversational assistant and is not optimized for open-ended dialogue.

2. Intended Use

Appropriate use cases

• Hypothesis refinement in β-cell stimulus–secretion coupling (e.g., identifying which state transitions could explain an observation)
• Experiment-design support (e.g., proposing perturbations that distinguish necessity vs sufficiency)
• Mechanistic interpretation of results under explicit experimental boundary conditions (isolated islets vs in vivo, acute vs chronic, species differences)
• Causality-aware writing assistance for mechanistic sections of research notes (with independent verification)

Intended users

• Researchers working in diabetes/β-cell biology
• Graduate students and advanced undergraduates with prior background in cell physiology

Not appropriate for

• Clinical decision-making, diagnosis, prognosis, or patient-facing communication
• Safety-critical or regulatory submissions
• Use as a substitute for primary literature review or experimental validation
• Broad “chatbot” use where no causal or mechanistic question is posed

3. Strengths in v0.6.1

• Improved identity stability compared to earlier internal iterations: reduced tendency to produce unrelated provider/model self-identification.
• Causality-first reasoning: more consistent separation of correlational observations from mechanistic claims, with emphasis on intervention-level admissibility.
• Boundary-condition awareness: more frequent explicit stating of experimental constraints (preparation, stimulus regime, time scale, species), and more careful scoping of conclusions.
• Reduced upstream-identity leakage relative to v0.5 and earlier: lower frequency of irrelevant provenance statements during scientific answers.
• Research-thinking emphasis: prioritizes what would discriminate competing mechanisms (necessity vs sufficiency, time ordering, bottlenecks) rather than enumerating pathways.

4. Known Limitations (Be Explicit)

This is an experimental research model. Known failure modes include:

• Occasional verbosity or answers that continue past the point of causal resolution.
• Inconsistent depth across prompts: similar questions can yield uneven mechanistic granularity.
• Template restatement: sometimes reiterates general causal reasoning patterns instead of fully instantiating them to the specific scenario.
• Non-convergence: may not converge to a single best explanation when the prompt implicitly contains multiple plausible mechanisms.
• No internal verification: does not perform ground-truth checking, literature retrieval, or automatic validation against experimental data.
• Prompt sensitivity: phrasing, assumed preparation, and the presence/absence of constraints in the question can substantially change the response.

Users should treat outputs as structured reasoning aids and should actively test claims against primary literature and experiments.

5. Comparison to Earlier Versions (Short)

• v0.4: treated as a stable mechanistic baseline with strong structural grounding.
• v0.5: introduced improvements in fluency and reasoning injection, but exhibited instability in stopping behavior and occasional identity leakage.
• v0.6.1: re-centers training on the v0.4 base and focuses on stability recovery: improved causal discipline, clearer boundary scoping, and reduced identity leakage. Some inconsistency in depth and occasional verbosity remain.

6. Usage Boundaries and Disclaimer

• Research use only. This model is intended for scientific reasoning support in β-cell research contexts.
• Not medical advice. Do not use the model to make clinical or therapeutic decisions.
• No guarantee of correctness. Outputs may contain errors, omissions, or unsupported causal inferences.
• Experimental validation required. Treat outputs as hypotheses or reasoning scaffolds unless independently verified.
