Launching the Ultraviolet Public Alpha

Ultraviolet is currently in alpha. It is a general-purpose programming language for AI-written code humans can review. The language hook is to make it easier for AI agents to write performant, safe, auditable code, and easier for humans to spot when they do not.

Ultraviolet's primary programming style is modal programming: organizing code around states, transitions, contracts, permissions, keys, structured concurrency, and execution domains. Reviewers need to see those surfaces directly when reading generated source.

The project currently has a public specification, compiler source, runtime source, and uv tool source. The next public work is hardening the compiler and surrounding infrastructure into a buildable, documented public alpha with CI, examples, diagnostics, and an open training corpus for LLMs that generate Ultraviolet source.

Blacklight Foundation is funding this work through three concrete goals: the $25,000 Public Alpha Launch Fund, the $50,000 Open LLM Training Corpus Fund, and the $120,000/year Maintainer-in-Residence Fund. These funds support alpha build hardening, release infrastructure, documentation, examples, diagnostics, contributor onboarding, public reports, and an open corpus for LLM training and evaluation.

Companies and individuals interested in supporting the work can choose a public support tier or fund a public milestone. Larger support conversations can start at sponsors@ultraviolet-lang.org .
