# Numenward Hub > A Christian fellowship for open AI research. For all mankind. ## Use the hub - [Models](https://hub.numenward.com/hub/): Search public model cards and select releases. - [Public catalog JSON](https://hub.numenward.com/api/v1/models): Read up to 50 public models, optionally filtered with ?q=. - [Create an account](https://hub.numenward.com/hub/signup/): Username and password registration with a one-time account recovery code. - [Upload a model](https://hub.numenward.com/hub/new/): Authenticated creation, model card, draft file upload, and release publication. - [Agent documentation](https://hub.numenward.com/agents/): Current interfaces and limits. Model uploads require the maintainer's authority. Limits are 512 MiB per file and 1 GiB per account. Published releases have fixed files with SHA-256 checksums. The service stores and distributes files; it does not execute models. A token-authenticated upload API is available; there is no remote MCP endpoint. ## Agent publishing Owner-issued Bearer tokens: /hub/tokens/. Documentation: /agents/. POST form data to /api/v1/models/create/, multipart files to /api/v1/releases/{id}/upload/, POST /api/v1/releases/{id}/publish/. Tokens expire in 30 days and can be revoked. Model uploads do not execute code. Filecoin/IPFS archive integration is operator-controlled and not funded or active yet. Browse external source metadata at /hub/explore/.
