Composo's custom AI models make evaluation easy.
We build you a custom evaluation model that can evaluate the accuracy & quality of your app with unparalleled precision and nuance.
Replace manual, human vibe-checks with a bespoke evaluation model, built just for you.
Designed to evaluate the most complex & subjective applications.
Human vibe-checks on quality don't scale, and LLMs as judges don't work for complex, subjective applications.
We build you a custom evaluation model that can evaluate the accuracy & quality of your app with unparalleled precision and nuance.
Proprietary, research-backed methods that are better than a human.
Based on models we custom build for you, which learn to your app over time.
Run evaluations without code, or just use our API directly.
Composo is hyper-personalised evaluation that you can rely on.
With a simple setup, just three lines of code are needed to link an app, allowing you to run evaluations straight out of the box.
There’s no need to leave Composo to run evaluations or iterate on app parameters such as prompts, models, or RAG settings. Or just use our API and plug it directly into your stack.
Engineers can keep modifying code in their environment, while others easily iterate and evaluate within Composo, enabling smooth collaboration between engineering and product teams.
Our solution works with any application, from chatbots to copilots, and supports complex setups including agents, RAG, and tool integrations.
We go beyond using LLMs for judgment and ground-truth comparisons, incorporating state-of-the-art hallucination detection and custom-trained evaluation models to deliver the best performance.
Our custom models learn to emulate human judgment, handling the complexity and subjectivity of LLM outputs with precision.

How secure is my data?
At Composo, data security is our top priority. We serve many enterprise customers in regulated industries and employ robust measures to safeguard your information.
Your application runs entirely on your own server and Composo only has access to inputs and outputs, never your underlying data or systems.
For highly sensitive data, we recommend anonymization. However, we also offer end-to-end encryption and dedicated instances where absolutely necessary.
Can Composo deploy on my company's infra?
Yes. Reach out to us to discuss further!
Does Composo work for complex applications such as agentic systems?
Yes, Composo is designed to be completely flexible to handle any complexity of application, whether it has agents, retrieval-augmented generation (RAG), tool use, or anything else.
It provides the ability to test and optimize both full end-to-end performance, as well as to isolate and evaluate the performance of individual components or agents within a GenAI system.
With evaluations built specifically for complex, highly specific domains, we make it easy to take your GenAI apps testing to the next level.
