The Only 2 AI Models Worth Using for eve Agents (CursorBench Analysis)

Tired of watching your token bill explode while building AI agents? In this video I break down CursorBench data to show you exactly which models deliver real performance without destroying your budget. We start with one of the smartest things the Vercel team did when shipping eve — bundling the full documentation locally inside node_modules so your coding agents (Cursor, Claude Code, Codex, etc.) can reference it instantly without burning tokens on web requests. Then we zoom out and build a simple, repeatable framework for choosing any AI coding model: Why Composer 2.5 is the highest-performing lowest-cost model on CursorBench and my default daily driver The exact math I use to kill most “premium” models (Opus 4.8 Max, GPT 5.5 Extra High, Fable 5 Low/High/Extra High/Max) When it actually makes sense to pay up for Fable 5 Medium (big migrations, messy codebases, complex refactors) A dead-simple way to evaluate any new model that drops next week If you’re building production eve agents or just want to stop overpaying for marginal gains, this video will save you serious money.
