Get Matched Platform SpecsHow CandyScript Lab Benchmarks Platforms
Our multi-step evaluation framework guarantees every assistant platform is vetted under reproducible conversational stress-tests.
Persona Prompt Injection
We test system prompt stability by introducing 150+ adversarial inputs to evaluate whether the assistant breaks character or leaks parameters.
Long-Horizon Recall
We insert specific conversational facts at turn 5, then query them at turns 50, 100, and 250 to measure episodic context degradation.
Latency & Token Throughput
We run automated ping tests from US-East, US-West, and EU servers, tracking First-Token Latency (FTL) and overall response fluidity.
Privacy & Data Governance
We verify CCPA/GDPR adherence, ensuring user chat logs are not leveraged for model retraining without explicit consent.
Insights from Developers & Conversation Designers
Real feedback from researchers, writers, and engineers who use CandyScript Lab to select their virtual assistant stack.
"CandyScript Lab saved our creative studio dozens of hours of trial and error. Their memory retention benchmarks for scripted assistants accurately predicted our API latency in production."
