Side-by-Side Comparison
Run one prompt across models and compare quality, tone, and consistency.
Project
Forkbench
Compare LLMs side-by-side with real-time metrics.
Forkbench is a developer-focused platform for testing and comparing multiple large language models in real time. Run the same prompt across providers, review outputs side-by-side, and track performance metrics like latency, token usage, and cost in one clean interface designed for rapid experimentation.
Key Features
Compare outputs, speed, and cost in one view.
Performance Metrics
Track latency, throughput, and cost to choose the right model.
Multi-Provider Support
Query OpenAI, Anthropic, Google, and more from one workflow.
How Forkbench Works
Three steps from prompt to decision.
1
Enter Your Prompt
Write one prompt to benchmark across models.
2
Select Models
Pick the models you want to test.
3
Compare Results
Review outputs with latency, token, and cost metrics.
