Multi-Agent AI Systems Aren't Just About Models
Architecture Changes Everything

We show how design choices alone can make AI agents 100× slower, less accurate, or fail at coordination - even with the same LLM.

Measured across multiple frameworks • Same model, same task • Controlled experiments

How Architecture Shapes Performance

Orchestration Overhead

How agents are scheduled can create 100× latency differences

Memory Design

Memory structure matters more than context size alone

Planning Style

Rigid planning interfaces can break reasoning accuracy

Agent Specialization

Procedural specialization design can improve F1 scores by 58 points

Agent Communication

Communication topology decides coordination success

Same LLM model • Same task

Different framework architectures

Direct LLM Call

Baseline: 1× latency

Multi-Agent Framework

Best: 1.3× latency

(efficient architecture)

Multi-Agent Framework

Worst: 117× latency

(poor architecture)

Based on controlled experiments across multiple frameworks

Key Takeaways

Some frameworks are 100× slower

Just due to design. Same model, same task, wildly different performance. Measured across graph-based, role-based, and GABM-style frameworks.

Memory structure matters more than context size

How information flows between agents determines what they remember.

Rigid planning interfaces break reasoning

Planning accuracy can drop by 30% with poorly designed architectural choices.

Communication topology decides coordination success

Success rates can drop from 90% to below 30% based on how agents communicate.

Why This Matters for Builders

Cost Impact

100× latency means 100× API costs. Architecture choices directly affect your infrastructure spend.

Time to Market

Choose the wrong framework architecture and you'll spend months optimizing instead of building features.

Scalability

Architectural bottlenecks become impossible to fix at scale. Get it right from the start.
