About gpt-load
GPT Load is a self hosted AI gateway written in Go and released under the MIT license. It gives applications a single entry point — one base URL and one AccessKey — for reaching many AI providers at once. Providers, accounts, credentials, models, and routing policy are configured in the bundled management UI rather than in application code.
