What a founder can learn
Founder takeaway
Evaluate new AI models through real production tasks, especially stubborn jobs your current tools cannot complete, rather than relying on generic benchmarks or demos.
Why it matters
A model upgrade can change what is practical to build, automate, or prototype. Testing it against your actual workflows reveals capability gains that could improve product velocity or unlock previously stalled ideas.
Relevant guides
Put it to work
Choose one recurring production task and one long-blocked experiment. Define success criteria, run both with the new model and your current best alternative, then compare output quality, completion time, and required intervention.
