Vico Labs Practical Evaluation: Who Is the Strongest "Digital Brain" in Multi-Agent Systems?

When building multi-agent teams with OpenClaw, many people encounter decision-making difficulties: GPT-4o, Claude 3.5, DeepSeek, GLM... with so many models available, how do you combine them for maximum efficiency and cost-effectiveness?
Vico Labs recently conducted several practical tests and found that "all top-tier models" isn't necessarily the best approach. Mixing different models for different roles often yields better performance and value. Today, we share our model selection notes.

Leader Bot (Coordinator)
Responsible for breaking down goals and developing the overall plan, requiring strong logic and a global perspective.
Recommended: GPT-4o or Claude 3.5 Sonnet
Practical experience: When handling complex multi-step tasks, these two models have strong comprehension, clear task decomposition, and rarely experience logical gaps.

Coder & Researcher (Executor)
Responsible for coding, API calls, and deep data retrieval, with core needs for structured output.
Dark horse recommendation: DeepSeek-V3 and Claude 3.5
Feedback: Claude is very stable in code generation accuracy, DeepSeek provides clear logic in Chinese contexts and has a significant advantage in API cost, making it suitable for high-frequency calls.

Writer & Critic (Creativity and Audit)
• Writer: Needs creativity and human touch → Claude series outputs feel more natural and personable
• Critic: Needs strict error scrutiny → GPT-4o performs reliably in identifying logical contradictions

How to choose between global models and domestic models?
• Long-term, multi-round tasks: Recommend prioritizing top international models with larger context windows that are less likely to "forget" or jumble words
• High real-time tasks (such as public opinion monitoring): Domestic models usually respond with lower latency

In terms of security, all Vico Labs models are accessed through encrypted gateways. When deployed locally, they are first tested in isolated environments to ensure stability and reliability.

Final note: There is no "best" model, only the "AI employee" that best fits the role. Currently, Vico Labs commonly uses GPT-4o for orchestration, Claude for creative tasks, and DeepSeek for execution, forming a cost-effective AI collaboration network.
