Evaluate & Benchmark
Multi-Variant LLM A/B Testing
Statistical A/B/n testing for 3+ model variants with ANOVA, Bonferroni correction, and sub-millisecond routing overhead.
<0.5ms routing overhead
The 4-step NEO workflow
- 1
Describe the task
State what you are comparing and the decision the benchmark should unblock.
- 2
Add context for NEO
Share prompts, graders, SLA targets, and providers to include.
- 3
NEO implements & delivers
NEO runs comparisons and ships a report with quality, latency, and cost.
- 4
Follow up or test it out
Re-run after changes and extend coverage where data is thin.
Ask NEO
How to run this scenario
Treat "Multi-Variant LLM A/B Testing" as a first-class benchmark: compare models with evidence on latency, quality, and cost.
Approach
What NEO focuses on
- Define tasks, rubrics, and baselines that match production
- Run structured suites across versions and providers
- Surface regressions and cost-quality tradeoffs before you ship
Outcomes
What you get
- Comparable scores across runs with enough context to trust them
- Regression signals when prompts, models, or infra change
- A defensible pick for model and routing under your SLAs
