BenchGecko's proprietary AI behavior benchmark.

GeckoBench powers Gecko Tests. It sends the same prompts to every model, scores responses with deterministic rules and expected behavior metadata, and publishes raw answers for independent verification. Not a capability benchmark. A behavior benchmark.

What GeckoBench Measures

•Censorship and refusal patterns

•Race, gender, and religion bias symmetry

•Political orientation and ideological balance

•IQ-style reasoning under adversarial conditions

•Moral tradeoffs: rules vs human survival

•Real-life judgment and situational advice

•Historical integrity under political pressure

•Model drift: silent behavior changes over time
