Stop Guessing Which Context Matters. Test It.

Isolate, measure, and optimize what's wasting tokens vs. what improves results

prune0 applies data-driven feature selection to prompt engineering, cutting costs while improving quality and latency.

The Problem

You're flying blind with your prompt context

Traditional ML has feature testing. Prompt engineering still relies on guesswork about what context actually matters.

Save Money: Cut Token Waste

Reduce LLM budget currently wasted on ineffective context. prune0 identifies exactly which context matters, dramatically reducing API costs while maintaining or improving quality.

Save Time: End Manual Testing

Transform hacky prompt & context experimentation into minutes of automated testing. prune0 eliminates the code-deploy-test loop, freeing your engineers to focus on building, not tweaking.

Be Rigorous: Data-Driven Context Selection

Bring scientific methodology to prompt engineering. Replace intuition with evidence by measuring the actual contribution of each context element, just like feature testing in traditional ML.

The Solution

Feature testing for prompt context

prune0 brings the scientific approach of feature selection to prompt engineering. Isolate variables. Measure impact. Optimize tokens.

Context Slicing

Automatically break down your context sources into testable slices - from chat history to vector store results to metadata - to identify what actually matters.

📊

Systematic Context Evaluation

Test individual context elements in isolation to measure their actual contribution to response quality, just like you'd test features in a traditional ML model.

Data-Driven Results

Replace guesswork with evidence. See exactly which context elements improve quality and which are just burning through your API budget.

The Process

How prune0 works

A systematic approach to context optimization without the hacky workflows

1

Connect your data sources

Import your conversation logs, memory blocks, and metadata directly from your existing stack. Works with any context source - vector DBs, graph DBs, user profiles, chat history, or custom data.

2

Design controlled experiments

Compare the same query with different context bundles - test recent interactions, semantic similarity, user metadata, and system configurations to measure which actually improve responses.

3

Analyze impact metrics

See comprehensive side-by-side analysis of token usage, response quality, and latency to identify which context elements provide value versus just increasing costs.

4

Deploy and monitor

Implement the optimized context strategy in your production environment with our simple API or export functions. Continue testing as your application evolves.

From our own experience:

When we first started testing, we were shocked to find that certain context we thought was essential (user profile data, system configurations) was actually hurting response quality while driving up costs. Only through systematic context testing did we discover what actually mattered.

The Impact

Transform your LLM economics

Stop the guesswork. Start measuring what matters.

Without prune0

  • High API costs from "just in case" context
  • Constantly copy-pasting prompts to test changes
  • Making educated guesses about which context matters
  • No way to isolate and test individual context elements
  • Frustrating deploy-test-wait-fix cycles for each change

With prune0

  • Significant API cost reduction
  • Improved response quality and relevance
  • Faster responses for better user experience
  • Data-driven optimization decisions
  • Continuous testing and improvement

Why prune0?

Not just another LLM monitoring tool

Unlike general-purpose tools like LangSmith or Weights & Biases, prune0 is built specifically for context optimization with a feature-testing approach to prompt engineering.
