the provider catalog
LM Studio
One provider: line moves a workflow between models — local first, keys via env vars that stay yours, no inference lock-in. The same file runs on a laptop Ollama and a frontier API; swapping is a one-word diff. Machines read the catalog at /providers/catalog.json; the binary answers nika catalog.

Beyond the named set, the engine embeds 22 more OpenAI-compatible endpoints — nika catalog lists every one. Models are aliases in the file (model: sonnet) pinned to exact upstream ids by the engine, so a run is reproducible even after a vendor rotates names. Try one in the playground, or install and go local first. Read the spec →
