A major bottleneck in AI progress is the gap between research and production. Researchers produce powerful models but often lack software engineering discipline. This results in code that is not portable, extensible, or robust, hindering the transition from a novel idea to a scalable, reliable product.

The team behind the 'Claudie' AI agent had to discard their work three times after getting 85% of the way to a solution. This willingness to completely restart, even when close to finishing, was essential for discovering the correct, scalable framework that ultimately succeeded.

Product leaders must personally engage with AI development. Direct experience reveals unique, non-human failure modes. Unlike a human developer who learns from mistakes, an AI can cheerfully and repeatedly make the same error—a critical insight for managing AI projects and team workflow.

Poolside views model building as an industrialized, end-to-end process, optimizing for the speed from a researcher's idea to a trusted experimental result. This engineering-first approach uses thousands of components to streamline everything from data pipelines to training and reinforcement learning, treating models as artifacts of the process.

The landscape of AI tools and tactics changes rapidly. Instead of chasing the latest setup guides, focus on understanding the underlying design and engineering philosophies. This knowledge is more durable and allows you to adapt to new tools as they emerge.

The key skill for an AI PM is knowing a model's current capabilities. This is built by intensely using the model and, crucially, asking it to introspect on its own unexpected behaviors to understand *why* it made a mistake, revealing gaps to fix.

The dominant AI development method involves creating a thin scaffold for a task, capturing errors, and then letting the model rewrite its own code to correct those mistakes. This "correction by correction" loop allows AI systems to improve their capabilities at an astonishingly rapid pace.

Theoretical knowledge from articles is insufficient for understanding AI models. True intuition is built through intensive, practical experimentation, such as feeding a model an entire codebase or extensive documentation. Pushing the AI to its limits is the fastest way to learn.

Building on AI requires creating custom infrastructure to fill performance gaps. As underlying models improve, founders must be prepared to delete this now-redundant code and upgrade their product vision to tackle the next set of challenges at the new frontier. This cycle of building and deleting is key to staying innovative.
