“Madhu Guru argued that PMs should understand the model frontier for their specific products and use cases by assessing each model size’s strengths, failures, and workarounds.”

#14 𝕏 Madhu Guru argued that PMs should understand the model frontier for their specific products and use cases by assessing each model size’s strengths, failures, and workarounds. He said anticipating capabilities 2–3 months ahead and using those trajectories to shape roadmaps is now a core part of the PM role.

“Madhu Guru advised enterprise AI leaders to make their stacks model agnostic by building an evaluation suite today and developing the capability to post-train open models within the next year.”

#9 𝕏 Madhu Guru advised enterprise AI leaders to make their stacks model agnostic by building an evaluation suite today and developing the capability to post-train open models within the next year. These investments enable teams to switch, customize, and compare models on their own workloads while optimizing quality, cost, and latency.

“Madhu Guru shared a laddered eval strategy tailored to each enterprise’s use cases, spanning multiple points on the cost-and-realism spectrum.”

#11 𝕏 Madhu Guru shared a laddered eval strategy tailored to each enterprise’s use cases, spanning multiple points on the cost-and-realism spectrum. In part 4, Guru highlights continually refreshed hill-climb long evals, regression checks, safety-focused smoke tests, and realistic but less controlled launch evals.

“Madhu Guru shared a recommendation to build a failure-modes taxonomy after v1 of your evals by reviewing the last 500 or 1,000 production interactions and clustering failures under specific names.”

#6 𝕏 Madhu Guru shared a recommendation to build a failure-modes taxonomy after v1 of your evals by reviewing the last 500 or 1,000 production interactions and clustering failures under specific names. These categories can inform targeted eval tests and create an improvement flywheel.

“Madhu Guru shared an eval strategy for AI products: define a rubric, use the best available measurement process to establish a trustworthy quality frontier, then reduce costs through automation, smaller judge models, sampling, and deterministic checks where relevant.”
