System 1 models embed AI directly into code paths

TypeSafe, founded by Diogo, a co-author of InstructGPT, is promoting a new engineering paradigm known as 'System 1 models.' These models operate within the critical path of code, similar to if-statements, rather than functioning as separate chat windows. This approach aims for reliability and speed by reducing the model's scope to making choices or estimating probabilities. The host contrasts this with the current large language model paradigm, where AI is often treated as a 'window' in traditional software. Other emerging areas of interest include 'interaction models' from Thinking Machine, which support full-duplex, back-and-forth communication, and 'continual learning AI' that learns in real-time. The host also highlights the importance of 'taste' in product development, citing Legora's legal document review and Carso's GrokBot as examples of narrowing possibilities to obvious, high-value solutions. The host endorses the System 1 model approach as a superior engineering paradigm that makes software 'smarter at every point' rather than relying on a single large model for all tasks. This shift represents a move away from general-purpose AI interfaces toward specialized, integrated components that enhance specific software functions.
