Which AI is best for the thing you are trying to do?
Character sheets for the AI era. Real benchmarks, translated into quest-fit recommendations — with confidence grades, evidence, and honest flaws. Not a fake #1 leaderboard.
What are you trying to do?
Vibe Code a New App
Go from idea to working product without drowning in scaffolding.
Work in a Large Existing Codebase
Navigate, change, and verify without breaking what already works.
Fix a Difficult Bug
Trace causes, isolate failure, and ship a minimal correct fix.
Design a Polished Frontend
Hierarchy, taste, and usability — not just “it renders.”
Run an Autonomous Coding Agent
Long runs, tools, and honest completion — with a named harness.
Deep Research and Analysis
Synthesise sources, reason carefully, and know when you are unsure.
Scored character sheets
Claude Opus 4.8 · API · High effort (default)
The expensive architect — pays for hard repos, long agents, and fewer retries.
Claude Sonnet 5 · API · High effort (default)
A polished code smith with expensive habits — still the sensible daily driver.
DeepSeek V4 Pro · API · Max effort
The open ceiling — near-frontier coding without the closed-model tax.
Gemini 3.1 Pro · API · High thinking
The reasoning multimancer — 1M context, strong science, calibrated knowledge.
GPT-5.6 Sol · API · Max effort
The ecosystem operator — max-effort Sol for hard agents, not cheap chat.
Grok 4.5 · API · High effort
The alt-frontier code smith — near-Opus agentic coding at a third the token bill.
Evidence before opinion
Every score ships with a methodology version, confidence grade, and evidence trail. Scores attach to exact Builds (API · effort · product). Public stats are peer ranks (≈40–95), not absolute IQ.
Peer formula & methodology →Stack models, don’t worship one
Quest pages suggest a multi-model Party — primary Fit, ceiling for hard mode, value for volume. Pick the job first, then the stack.
