Multi-agent systems work well for easily parallelizable, "read-only" tasks like research, where sub-agents gather context independently. They are much trickier for "write" tasks like coding, where conflicting decisions between agents create integration problems.

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.

Andrej Karpathy's 'Software 2.0' framework posits that AI automates tasks that are easily *verifiable*. This explains the 'jagged frontier' of AI progress: fields like math and code, where correctness is verifiable, advance rapidly. In contrast, creative and strategic tasks, where success is subjective and hard to verify, lag significantly behind.

The current focus on pre-training AI with specific tool fluencies overlooks the crucial need for on-the-job, context-specific learning. Humans excel because they don't need pre-rehearsal for every task. This gap indicates AGI is further away than some believe, as true intelligence requires self-directed, continuous learning in novel environments.

To improve the quality and accuracy of an AI agent's output, spawn multiple sub-agents with competing or adversarial roles. For example, a code review agent finds bugs, while several "auditor" agents check for false positives, resulting in a more reliable final analysis.

Companies like OpenAI and Anthropic are not just building better models; their strategic goal is an "automated AI researcher." The ability for an AI to accelerate its own development is viewed as the key to getting so far ahead that no competitor can catch up.

Karpathy argues against the hype of an imminent "year of agents." He believes that while impressive, current AI agents have significant cognitive deficits. Achieving the reliability of a human intern will require a decade of sustained research to solve fundamental problems like continual learning and multimodality.

Karpathy identifies the AI community's 2010s focus on reinforcement learning in games (like Atari) as a misstep. These environments were too sparse and disconnected from real-world knowledge work. Progress required first building powerful representations through large language models, a step that was skipped in early attempts to create agents.

To build robust social intelligence, AIs cannot be trained solely on positive examples of cooperation. Like pre-training an LLM on all of language, social AIs must be trained on the full manifold of game-theoretic situations—cooperation, competition, team formation, betrayal. This builds a foundational, generalizable model of social theory of mind.
