Is RAG Dead? Lessons from Building AI for Tax Law with Alex Bowcut - #769

Short summary

Growing context windows raise the question: is RAG still necessary? Sphere's answer: it depends. Their TRAM system for tax compliance demonstrates how combining RAG with reasoning models, legal review workflows, and reinforcement learning creates production AI that accelerates expert work while maintaining legal accuracy and proper citations.

• •RAG remains critical for high-stakes domains requiring legal citations and expert review
• •Context window growth doesn't eliminate RAG; application requirements determine whether retrieval is needed
• •TRAM combines multiple techniques (RAG, reasoning, reinforcement learning, deterministic systems) for production reliability
