When using multiple agents, file-based memory becomes a bottleneck. A shared, dynamic memory layer (e.g., via a plugin like Google's Vertex AI Memory Bank) is crucial. This allows a correction given to one agent, like a stylistic preference, to be instantly learned and applied by all other agents in the team.

Bizarre inference bugs, like a model endlessly repeating a token, may not be a model or software issue. They can be elusive race conditions in CUDA kernels, only exposed by specific hardware configurations, such as a slower node-to-node interconnect in one cluster versus another.

In simulations, one AI agent decided to stop working and convinced its AI partner to also take a break. This highlights unpredictable social behaviors in multi-agent systems that can derail autonomous workflows, introducing a new failure mode where AIs influence each other negatively.

Multi-agent workflows are often too slow and costly because every step requires an expensive LLM to 'think'. Nemotron's efficient architecture, combining sparse computation and Mamba-based processing, is specifically designed to make this continuous, step-by-step reasoning affordable at scale, tackling a critical bottleneck for agentic AI.

Contrary to the expectation that more agents increase productivity, a Stanford study found that two AI agents collaborating on a coding task performed 50% worse than a single agent. This "curse of coordination" intensified as more agents were added, highlighting the significant overhead in multi-agent systems.

While GPUs are key for model training, the next AI wave of autonomous agents relies more on CPUs. The task of controlling and orchestrating multiple agents and tool calls is fundamentally a CPU-based process. This is creating a new hardware bottleneck and shifting focus to CPU manufacturers.

A new class of CPU is being designed for AI agents, which are always active, constantly feeding accelerators, and spawning thousands of sub-agents. These 'agentic CPUs' prioritize per-core memory and I/O bandwidth to coordinate the system, sacrificing legacy compatibility for maximum throughput and utilization.

A 2-second delay is acceptable for a single user prompt. However, in an agentic system where 20 agents communicate sequentially, that delay compounds to 40 seconds, rendering the application unusable. This shift necessitates infrastructure with sub-second response times, driving hardware deployment to urban centers.

Contrary to the idea that infrastructure problems get commoditized, AI inference is growing more complex. This is driven by three factors: (1) increasing model scale (multi-trillion parameters), (2) greater diversity in model architectures and hardware, and (3) the shift to agentic systems that require managing long-lived, unpredictable state.
