Production AI Engineering starts with Evals

Oct 11, 2024 · 1:56:16

Ankur Goyal, founder and CEO of Braintrust, argues that evaluation is the core workflow of production AI engineering and shows how his platform makes evals accessible to software engineers. Drawing from his experience at SingleStore and Impira, he details Braintrust's evolution from an eval tool into an end-to-end AI development platform used by Stripe, Zapier, Vercel, and other top AI teams. He shares market data: OpenAI handles over 95% of production workloads, fine-tuning is declining, and open-source models account for under 5% due to reliability issues. Ankur explains why he avoided building a vector database—the real challenge is permissions and joins, not vector search—and predicts o1-style reasoning will replace complex agent frameworks. He reveals Braintrust's differentiators: hybrid on-prem, TypeScript-first SDK, and declarative eval structures.

The State of AI in production — with David Hsu of Retool

Feb 7, 2024 · 1:06:52

Retool CEO David Hsu shares insights from the company's 2023 State of AI survey, revealing that most AI adoption remains internal and that the hype may be overrated—52% of 1,600 respondents said AI is overrated, and only 27% have AI in production, with 66% of those being internal use cases. He explains Retool's developer-first philosophy, their choice of open-source PG Vector over proprietary solutions, and why they intentionally raised less money at lower valuations to avoid over-dilution. Hsu describes Retool's shift from sales-led to bottom-up growth to reach millions of developers, and highlights the importance of AI workflows over simple chatbots, citing a clothing manufacturer that uses Retool apps with DALL-E to generate patterns. He discusses the competitive landscape, predicting open-source models will eventually catch up to OpenAI, and shares philosophical views on AGI using the plane-vs-bird analogy.
