Calling an LLM API in production runs into the same reliability problems as calling any external service: occasional timeouts, rate limits, transient failures, and responses that don't quite match the shape your code expects. Most teams end up writing ad-hoc retry loops and validation checks by hand for each provider; VernLLM packages that logic once so you don't have to rebuild it per project. VernLLM is a free, open-source (MIT), TypeScript-only library that adds retry logic with exponential backoff and jitter, configurable per-attempt timeouts, circuit-breaker behavior, pluggable response caching, and structured output validation via Zod schemas on top of chat completion calls to OpenAI, Anthropic, Gemini, Bedrock, and other OpenAI-compatible providers. It also tracks token usage and supports pluggable logging, all in a genuinely lightweight package — 12.1 kB minified, 4.4 kB gzipped. It's distributed via npm as vern-llm, with source on GitHub, and is licensed for both personal and commercial use.

An open-source gateway that lets an AI agent query your sensitive data while mathematically guaranteeing it can never learn about any single individual in that data.
A free leaderboard that blends 10 independent AI benchmarks into a single, transparent score so you can compare frontier AI models without wading through a dozen separate charts.
An AI tool that turns plain-language descriptions into working, exportable code, built and hosted entirely on European infrastructure for teams that need their data to stay in the EU.
A cloud-hosted AI agent platform that lets you automate desktop and browser tasks by describing what you want done, no infrastructure to manage.
A marketplace where people record and submit video, then get paid an hourly rate, to build up the training data that AI video models are trained on.
Keeps long AI agent sessions cheap by summarizing what happened into short notes instead of replaying the entire conversation history on every single turn.
Lets you keep using the Claude Code interface you already know while quietly routing requests to cheaper or different models, with a hard budget cap so you never get an unpleasant surprise bill.
A shared chat room where your different AI coding agents — Claude Code, Codex, Cursor — can actually talk to each other, instead of you manually copy-pasting context between them.
Adds a chat sidebar to any YouTube video so you can ask what it's about, get an AI summary, and jump straight to the moment you actually need, instead of scrubbing through it.
One AI workspace where you throw in a rough idea or a source file and get back a presentation, document, website, or piece of media, instead of switching between five separate AI apps.
