# Kiln AI: The Local-First Infrastructure for High-Performance AI Systems

### Vision & Mission

Kiln AI is an open-source infrastructure platform dedicated to empowering software teams to build, evaluate, and optimize AI systems with surgical precision. By bridging the gap between experimental prompt engineering and production-ready software, Kiln provides robust, dataset-driven tooling that mirrors the reliability of Git and CI/CD for the generative AI era.

### The Core Philosophy: "Many Small Evals"

Kiln’s unique approach is rooted in replacing monolithic, brittle evaluations with a "many small evals" methodology. Recognizing that AI outputs are inherently non-deterministic, Kiln leverages a local-first architecture to facilitate rapid synthetic data generation—allowing teams to create comprehensive evaluation suites in under five minutes. This ensures continuous testing remains maintainable while safeguarding enterprise data privacy.

### Architecture & Workflow

Delivered via an open-source Python library and a source-available desktop application, Kiln prioritizes security by storing datasets locally on the user's hardware.

• Integration: Seamlessly connects to major providers including Ollama, OpenAI, AWS, and Vertex AI.
• Collaboration: Enables non-technical stakeholders (PMs, QA, Designers) to interact with a visual UI for rating and human annotation.
• Version Control: Refined datasets are version-controlled via Git, fostering cross-functional alignment and rapid prompt iteration.

### Leadership & Heritage

Founded in 2024 by Steve Cosman—a veteran engineer from Apple and Microsoft with a track record of scaling AI systems for billions of users—Kiln AI is headquartered in Toronto, Canada. The company is backed by the MIT-affiliated E14 Fund and maintains a steadfast commitment to an open-source, privacy-first engineering culture.

### Strategic Positioning

Kiln AI serves as the essential "Bridge" between subjective AI exploration and rigorous engineering discipline. In a landscape crowded with heavy, cloud-centric MLOps platforms, Kiln distinguishes itself by championing a developer-friendly, Git-centric, and privacy-first paradigm. It transforms AI evaluation from a pre-release hurdle into an iterative, collaborative habit.
