The Most Important New Skill for Product Managers in 2026: AI Evals Masterclass

AI features don't fail because of the model. They fail because nobody evaluated them. Ankit Chukla has taught thousands of PMs how to build evals, and today he's open-sourcing the knowledge he normally charges thousands for — for free.

WHAT IT’S REALLY ABOUT

Why AI evals become the core PM skill for 2026 success

  1. The speakers argue that most AI features fail in production not due to model quality, but because teams ship without robust evaluation systems that reveal errors, drift, and misbehavior.
  2. They present a practical framework: define expected behavior and success criteria, convert them into metrics, build a representative dataset, and implement code/LLM/human evals to iteratively improve prompts, models, tools, and orchestration.
  3. Offline evals are positioned as the AI PRD—engineers “hill-climb” eval scores until quality thresholds are met before shipping major releases.
  4. Online evals and observability extend evaluation into production via sampling, drift detection, and user feedback signals (thumbs up/down plus behavioral “soft feedback”).
  5. A detailed fintech case study (INDMoney Mind / Robinhood-like stock Q&A) shows how to translate regulatory constraints into eval dimensions, thresholds, gating rules, and ongoing monitoring cadence.

IDEAS WORTH REMEMBERING

5 ideas

Evals are the missing “truth” layer for AI products.

Because LLM outputs are stochastic, a product can appear fine in demos while failing in real usage; evals create repeatable checks for accuracy, safety, relevance, and UX constraints so you can trust what you ship.

Start eval design with explicit expected behavior and success criteria.

Write guardrails like “be an analyst, not an advisor,” length limits, and prohibited actions (e.g., no buy/sell recommendations), then translate them into measurable metrics and pass/fail thresholds.

Your dataset is the highest-leverage part of the entire eval system.

Collect representative and adversarial inputs from production logs, user research, subject matter experts, and synthetic generation; weak datasets produce misleading evals and fragile products.

Use the cheapest evaluator that can reliably measure each metric.

Structural constraints (length, formatting, presence of terms) should be code-based, subjective qualities (helpfulness, tone, balance) can use LLM-as-judge, and high-stakes cases should escalate to human review.

Offline evals function as the AI PRD and enable “hill-climbing” to ship readiness.

PM-defined evals give engineers a clear target (raise low-scoring dimensions to thresholds) and act as regression tests before launches or major changes to prompts/models/tools.

WORDS WORTH SAVING

5 quotes

Your AI feature fails not because of the model, but because you didn't evaluate it.

— Ankit Chukla

If you are shipping AI features without evaluations, your product is lying to you and you have no idea.

— Ankit Chukla

The way the best AI companies work is that the AI PM defines these evals, and that is basically the PRD for the AI engineers.

— Aakash Gupta

If you are not doing offline evals correctly, then you have not even created a product that can be actually launched to the real audience.

— Ankit Chukla

Evaluations are not optional. They are the guardrails for all the AI-driven outcomes.
