Synapse: A Local Ollama-Based Multi-Agent Collaboration Framework for AI-Driven Autonomous Iterative Creative Optimization

Synapse is an experimental multi-agent AI framework whose core feature is enabling iterative collaboration between agents based on local Ollama models, covering the entire process of creative generation, evaluation, scoring, and refinement. This framework does not rely on external APIs, supports local deployment, and balances data privacy protection with cost control. Through collaborative work among multi-role agents, it forms a closed-loop optimization process, suitable for tasks requiring repeated polishing such as creative writing and solution design. The project is open-source (MIT License), maintained by launchAxis, and the source code is available on GitHub.

With the improvement of LLM capabilities, single models have limitations in tasks such as multi-angle thinking and critical evaluation, leading to the emergence of multi-agent systems due to their collaborative advantages. Traditional multi-agent solutions rely on cloud APIs, which pose data privacy risks and cost issues. Synapse chooses to be fully based on local Ollama models, allowing users to build workflows in a private environment, ensuring data security while reducing usage costs.

Synapse is designed around 'collaborative iteration' and defines four agent roles:

• Generator: Produces initial ideas and solutions
• Critic: Conducts critical analysis of content, pointing out problems and areas for improvement
• Scorer: Quantitatively evaluates quality according to preset standards
• Refiner: Iteratively improves content based on feedback Agents collaborate via message passing to form a closed-loop process. Users can configure each role with different combinations of local models according to the task.

Synapse is implemented in Python and communicates with the local Ollama service via HTTP API. Core components include:

• synapse.py: Defines the agent base class and collaboration protocol
• docs/: User guides and architecture descriptions
• tests/: Unit and integration tests Typical workflow:

1. Initialization: Users define task descriptions and output formats
2. Generation: Generator produces initial solutions
3. Review: Critic and Scorer evaluate the solution
4. Improvement: Refiner modifies based on feedback
5. Iteration: Repeat the review-improvement steps until a threshold or maximum number of times is reached This workflow is suitable for scenarios requiring repeated polishing such as creative writing and code review.

Synapse's localized features give it significant advantages in the following scenarios:

• Enterprise Creative Workshops: Protects commercial secrets, AI collaboration optimizes solutions
• Personal Knowledge Management: Privacy-first, assists in note organization and writing optimization
• Educational Research: Ensures data security, supports literature reviews and research design
• Cost-Sensitive Applications: Reduces API call costs, suitable for startups and individual developers

Key differences between Synapse and cloud-based multi-agent solutions:

Feature	Synapse	Cloud-based Multi-Agent Solution
Data Privacy	Fully local, no data leaves the environment	Depends on service provider's privacy policy
Operation Cost	Only requires hardware resources	Token-based billing, high cost for frequent use
Model Selection	Supports all local Ollama models	Usually limited to specific models
Network Dependency	Can run offline	Requires stable network
Customization	Open-source, deeply customizable	Limited by platform capabilities
Limitations: Higher hardware requirements; model capabilities may not match top cloud models, so users need to balance their needs when choosing.

Synapse is an experimental project under active development, with potential directions including:

• Supporting more agent role definitions
• Introducing a visual workflow editor
• Enhancing external tool integration
• Optimizing concurrent execution performance The project uses the MIT License and welcomes community contributions. Developers can quickly understand the multi-agent collaboration mechanism through the source code and documentation to build custom applications.

Synapse represents the evolutionary direction of AI architecture from single models to multi-agent collaboration. In today's era where data privacy and cost control are increasingly important, localized multi-agent solutions have broad application prospects. Both enterprise users and individual developers can gain inspiration from Synapse and explore new possibilities for AI collaboration.
