The Problem

LLMs make coding mistakes.
They're terrible at fixing them.

How It Works

Drop into your existing workflow

Benchify transforms your LLM workflow from expensive retry loops to reliable, single-pass code generation.

Before: Retry Loop Hell

Typical LLM Integration
// Get code from LLM
let files = await generateCode(prompt);

// Check for errors in generated code
while (containsErrors(files)) {
  for (error in findErrors(files)) {
    // Wait for LLM to fix each error
    const fixes = await fixWithLLM(error, files);
    // Apply each fix
    applyFixes(fixes, files);
  }
}

// Send files to sandbox
await createSandbox({
  files,
});
Multiple API Calls
$0.20+ per retry
Slow Response
1-3 minutes

After: Benchify Integration

Benchify Integration
// Get code from LLM
let files = await generateCode(prompt);

// Fix potential issues with Benchify
files = await benchify.runFixer({
  files
});

// Send files to sandbox
await createSandbox({
  files,
});
Single API Call
$0.02 fixed cost
Fast Response
1-2 seconds
