# Feature catalog — ollama/ollama

Scanned commit 6383a0fa9cbf97494b847226e189f6e36b401a08 (2026-09-18). Generated by codevetter codevetter 1.12.0 on 2026-09-22.

User-facing surface = CLI subcommands + REST endpoints + OpenAI/Anthropic compat shims + a desktop chat app. Features cover the full model lifecycle (pull/create/push/copy/show/list/ps/delete), inference (generate/chat/embed with streaming NDJSON, thinking, tools, vision/audio, structured output, logprobs), cloud remote inference on ollama.com, experimental web search/fetch, and Codex Desktop integration via a loopback proxy.
- CLI commands: create, show, run, stop, serve (alias start), pull, push, signin/login, signout/logout, list, ps, cp, rm; hidden commands `runner` (MLX runner entrypoint) and `gpu-discover` — [cmd/cmd.go#L2393-L2595](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/cmd/cmd.go#L2393-L2595)
- Native API endpoints: /api/generate, /api/chat, /api/embed, /api/embeddings, /api/pull, /api/push, /api/tags (GET+HEAD), /api/show, /api/delete, /api/create, /api/blobs/:digest (POST+HEAD), /api/copy, /api/ps, /api/me, /api/signout, /api/version, /api/status — [server/routes.go#L1892-L1930](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/server/routes.go#L1892-L1930)

- `ollama create` supports two paths: classic Modelfile+API (parser.ParseFile -> CreateRequest -> blob upload -> /api/create) and in-process safetensors import with --quantize/--draft-quantize/--force when the server is local (OLLAMA_CREATE_REMOTE forces remote) — [cmd/cmd.go#L220-L315](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/cmd/cmd.go#L220-L315) [cmd/cmd.go#L317-L400](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/cmd/cmd.go#L317-L400) [parser/parser.go#L56-L120](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/parser/parser.go#L56-L120) [create/create.go#L22-L100](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/create/create.go#L22-L100)

- Cloud/remote models: models whose Config has RemoteHost+RemoteModel are proxied by ChatHandler to remoteURL via api.NewClient, gated by envconfig.Remotes() allowlist and OLLAMA_NO_CLOUD; :cloud model refs take cloudPassthroughMiddleware on /v1 routes (inferred) — [server/routes.go#L2555-L2621](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/server/routes.go#L2555-L2621) [server/routes.go#L1935-L1946](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/server/routes.go#L1935-L1946) [envconfig/config.go#L166-L177](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/envconfig/config.go#L166-L177) [internal/cloud/policy.go](https://github.com/ollama/ollama/blob/6383a0fa9cbf97494b847226e189f6e36b401a08/internal/cloud/policy.go)
