- QuickstartGet a key and send your first request in a few minutes.
- ModelsThe two checkpoints, their IDs, limits and reasoning controls.
- AgentsRun coding agents on Lyber, or build your own tool loop.
- Tool callingLet the model call your functions and continue with the results.
- Security reviewStart an API or web audit, challenge the findings and recheck the full flow.

How Lyber works
Lyber serves abliterated checkpoints: open-weight models whose refusal behavior has been removed. Both sit behind one endpoint that speaks the OpenAI Chat Completions format, so the official OpenAI SDKs, and the frameworks built on them, work by changing the base URL and the key.
Every request names its model explicitly. Lyber never substitutes another model for your choice, and every response carries the ID of the model that answered, in the model field and the x-lyber-model header.
