Beyond the Prototype: Using AI to Write High-Quality Code - Josh Albrecht, Imbue

This talk focuses on mastering AI evaluation, moving from initial development to production. It emphasizes that even the best large language models (LLMs) require a robust testing framework due to issues like hallucinations and performance degradation with changes. Effective evaluation helps answer critical questions about model selection, cost-effectiveness, brand consistency, and ongoing improvement, ultimately reducing development time, costs, and enabling faster iteration.

This talk introduces an evaluation framework for AI product managers (PMs) focused on shipping reliable AI applications. It emphasizes the critical need for robust evaluation, analogous to software testing but adapted for the non-deterministic nature of AI models. The framework aims to provide PMs with tools and methodologies to build confidence in AI product performance, moving beyond subjective "vibe coding" to data-driven "thrive coding."

The core thesis of this talk is that 2025 will finally be the year for robust AI evaluation, driven by the convergence of several key factors. The increasing understanding of AI by business leaders, coupled with budget shifts towards generative AI projects, has set the stage. Crucially, the rise of agentic systems, which make decisions and take actions, introduces significant complexity and risk, making rigorous evaluation a necessity rather than an option.

This talk emphasizes that robust evaluations are the most critical, yet often overlooked, component for successfully scaling generative AI workloads. The speaker argues that evaluations are not merely for measuring quality but are primarily a tool for discovering problems within AI systems. Implementing a strong evaluation framework is presented as the key differentiator between a project that remains a science experiment and one that achieves production-level success and scalability.

Logan Kilpatrick of Google DeepMind discussed a year of progress with Gemini models and outlined future developments. The talk highlighted the release of a new Gemini 2.5 Pro model, emphasizing its improved performance across benchmarks and its role as a turning point for the Gemini family. Kilpatrick also touched upon the organizational shifts within Google that have integrated research and product teams, enabling faster delivery of AI capabilities to both consumers and developers.
