Why? LLM-applications have hidden risks

Uncertainty of AI performance

3000+ AI harms reported: The non-determenistic nature of LLMs introduces significant risks when scaling applications to production, making quality assurance difficult.

Manual optimization process

AI teams spend countless hours tweaking prompts, model selection, vibe-checking to get the desired output. A non-reproducible process that creates a bottleneck in development.

Move from PoC to production

90% of GenAI projects fail to reach production.
The absence of a structured framework prevents many innovations from seeing the light of the day.

How LangWatch guarantees quality

The first platform that learns to evaluate just like you and find the right prompt and model for you

Check the video above for a sneak peak into LangWatch

Measure performance while building at every step

Evaluate your entire pipeline on and off-line, not just prompts, allowing to build on top of very reliable parts, it’s like unit test for LLMs.

10x faster to get the best prompt & model

Using the techniques behind DSPy - our platform replaces manual work, and takes care of finding the right prompt or model in minutes instead of weeks.

Built for developers enabling to bring Domain Experts

Bring your Legal, Sales, Customer, HR, Health, Finance or any other domain expert in the loop. Focus on coding, not prompting.

Deliver reliable quality and high-grade enterprise security

Explain the performance numbers, having evidence and reporting to bring to the compliance and business teams.

“I’ve seen a lot of LLMops tools and LangWatch is solving a problem that everyone building with AI will have when going to production. The best part is their product is so easy to use.”

Kjeld Oostra. - AI Architect, Entropical AI agency

Why writing prompts yourself when AI can do that for you?

DSPy optimizers to automatically find the best prompt and few shot examples for the LLMs, including MIPROv2.
Drag-and-drop prompting techniques: ChainOfThought, FewShotPrompting, ReAct.
Compatible with all LLM models, just switch and let the optimizer fix the prompts.
Track optimization progress with LangWatch DSPy Visualizer.
