If you’re using AI + automation to start or grow your business, you’ll run into the same problem most of us do:
How do you make AI apps that are reliable, fast, and easy to improve?
That’s where TensorZero comes in. It’s a free, open-source tool you can self-host that helps you manage and improve apps built with large language models (like GPT, Claude, etc).
What It Does
- One connection for all AI models → OpenAI, Anthropic, Google, AWS, and more. No more juggling different APIs.
- Testing & monitoring → See what answers your app is giving, collect feedback, and test new prompts before going live.
- Improvement loop → Learn from real users, tweak your prompts or models, and make your system better over time.
- Safe experiments → Run A/B tests so you can try changes without breaking what already works.
Why It’s Useful for Business
- Keeps your AI apps from breaking when you scale.
- Lets you see how the AI is working instead of guessing.
- Helps you lower costs and improve results step by step.
- No vendor lock-in — it’s open source and yours to run.
This is especially helpful if you’re:
- Building AI-powered automation workflows (like in n8n, Make, or Zapier).
- Creating customer support bots or content tools.
- Running an AI agency or offering AI services.
