Giving Simulated Cells a Voice: Evolving Prompt-to-Intervention Models for Cellular Control
This paper introduces ZapGPT, a novel framework that bridges natural language and cellular dynamics in simulated environments. It enables users to guide simulated cell collectives (e.g., clustering or scattering) using natural language prompts. The system uses a Prompt-to-Intervention (P2I) model, optimized by evolutionary algorithms, to translate prompts into spatial vector fields. A Dynamics-to-Response (D2R) model, built on a vision language model, interprets cellular dynamics back into natural language for evaluation. The framework demonstrates language-guided, evolutionary control of decentralized behaviors, laying the groundwork for more complex real-world biological and synthetic systems.

Prompt-to-Intervention (P2I)
The P2I model translates natural language prompts into spatially actionable vector fields that drive cellular dynamics. It uses a precomputed BERT embedding of the prompt, which is then processed through a feed-forward neural network (FFN) to generate a flattened representation of the vector field. This output is reshaped into a 3D tensor defining the direction and magnitude of the vector in each grid cell. This establishes a bridge between symbolic instructions and cellular dynamics.
Dynamics-to-Response (D2R)
The D2R model evaluates the alignment between cellular behaviors and the original language prompt. It leverages a pretrained vision-language model (VLM), specifically Moondream2, to interpret simulation outputs (e.g., time-series plots and spatial configurations) and generate concise textual responses ('Clustering' or 'Scattering'). The VLM's output is restricted to one-word labels for consistent evaluation, and a semantic loss metric quantifies the alignment between the original prompt and the D2R response.
Evolutionary Algorithms (EAs)
EAs, including (1+1) Evolution Strategy and Genetic Algorithms, optimize the P2I model's neural network weights. They are crucial for exploring high-dimensional, nonlinear search spaces where traditional backpropagation is challenging due to sparse rewards and non-differentiable components. EAs rely solely on reward evaluations, providing an alternative to gradient-based learning. While (1+1)-ES is effective for simpler tasks, Genetic Algorithms are more robust for complex vector field configurations and balancing multiple objectives.
ZapGPT Pipeline Overview
| Feature | (1+1) Evolution Strategy | Genetic Algorithms (GA) |
|---|---|---|
| Search Space | Local, intuitive hill-climbing | Larger, more robust exploration |
| Complexity Handling | Effective for simpler configurations (e.g., 2x2, 3x3 grids) | More effective for complex configurations (e.g., 5x5, 10x10 grids) |
| Objective Balancing | Struggles with multiple objectives in higher dimensions | Balances local proximity and global cohesion effectively |
| Mechanism | Mutation only | Selection, crossover, mutation |
Future Directions: Real-World Applications
The ZapGPT framework can be extended to real-world biological experiments, generating optimized intervention schedules for chemical signals or drugs in bioreactors. It also has significant potential in swarm robotics for controlling distributed agents to achieve coordinated behaviors like clustering or dispersing. This language-guided strategy provides high-level control over dynamic, multi-agent systems, highlighting broad implications for integrating natural language with dynamic system control.
