Shipping Blind

Most LLM teams still evaluate changes with manual spot checks and intuition. Without structured datasets, automated metrics, and traceable experiments, hallucinations and quality regressions ship silently to production. At the same time, costs and latency can spiral out of control when switching models without a shared benchmark.

Measure before you ship

LLM EvalForge brings datasets, experiments, scoring, observability, and human review into one workflow.

1. Build Datasets
2. Configure Models
3. Run Experiments
4. Score Outputs

Visualize your model performance

Get instant, actionable insights with our interactive observability dashboard. Compare accuracy against latency and cost in real-time as your evaluations run.

Bigger AI models aren't always the best choice.

Many teams default to massive, expensive frontier models for everything. But for specialized, repetitive tasks, a smaller fine-tuned model often performs just as well—at a fraction of the cost and latency.

EvalForge helps you uncover these inefficiencies. By testing multiple models against the same benchmark, you can confidently switch to a smaller model knowing exactly how it impacts your bottom line and user experience.

Continuous Improvement

Build your AI Data Flywheel.

EvalForge powers a self-improving loop where real-world interactions continuously refine your AI models. By automating data curation, model evaluation, and guardrail enforcement, your AI agents get smarter, safer, and cheaper to run over time.

1. Capture & Curate

Collect human feedback and edge cases from production to form high-quality evaluation datasets.

2. Evaluate

Automatically score new data against custom benchmarks to verify answers align to application requirements.

3. Guardrails Implementation

Ensure specific privacy, security, and safety requirements are met when interacting with users.

4. Refine & Deploy

Use curated ground-truth data to fine-tune smaller, faster models, slashing inference costs while preventing model drift.

Open Ecosystem

Run anywhere. Evaluate anything.

EvalForge is designed to integrate seamlessly with the open-source AI ecosystem. Import your favorite datasets and models directly from Hugging Face to instantly access a massive library of resources, increasing your chances of finding the perfect fit for your specific use case.

Need maximum privacy or zero latency? EvalForge fully supports connecting to locally running models using Ollama, vLLM, or LM Studio, ensuring your sensitive data never leaves your environment.
