# Using supermemory local with different providers

> Copy-paste .env setup for Ollama, OpenAI, Anthropic, Gemini, and OpenRouter

Supermemory local needs one model provider to power summaries, contextual chunking, and memory extraction. Pick the tab for whichever one you already have a key for. For the full variable reference (fast/text model overrides, offline setup, tuning), see [Configuration](/docs/self-hosting/configuration).

<Tabs>
  <Tab title="Ollama">
    Fully offline — no API key leaves your machine. Any OpenAI-compatible local runner works the same way (LM Studio, vLLM, llama.cpp server); this is the Ollama version.

    ```bash theme={null}
    ollama pull gpt-oss:20b
    ```

    ```bash .env theme={null}
    OPENAI_BASE_URL=http://localhost:11434/v1
    OPENAI_API_KEY=ollama        # any non-empty string — Ollama doesn't check it
    OPENAI_MODEL=gpt-oss:20b
    ```

    `gpt-oss:20b` is a good default for a laptop-class GPU. Bigger models work if you have the VRAM — set `OPENAI_MODEL` to whatever you've pulled.
  </Tab>

  <Tab title="OpenAI">
    ```bash .env theme={null}
    OPENAI_API_KEY=sk-...
    ```

    That's it — defaults to `gpt-5.1`. Override with `OPENAI_MODEL` if you want a different one.
  </Tab>

  <Tab title="Anthropic">
    ```bash .env theme={null}
    ANTHROPIC_API_KEY=sk-ant-...
    ```

    Runs on `claude-haiku-4-5` — this one isn't currently configurable via env var.
  </Tab>

  <Tab title="Gemini">
    ```bash .env theme={null}
    GEMINI_API_KEY=...
    ```

    Runs on `gemini-3.1-flash-lite-preview` — also not currently overridable. This is the only key that also unlocks image, video, and high-fidelity PDF understanding (see the [full provider table](/docs/self-hosting/configuration#llm-providers)).
  </Tab>

  <Tab title="OpenRouter">
    OpenRouter isn't a native provider — it's OpenAI-compatible, so it slots into the same `OPENAI_BASE_URL` path as Ollama:

    ```bash .env theme={null}
    OPENAI_BASE_URL=https://openrouter.ai/api/v1
    OPENAI_API_KEY=sk-or-...
    OPENAI_MODEL=openai/gpt-4o-mini
    ```

    Set `OPENAI_MODEL` to any model slug from [OpenRouter's model list](https://openrouter.ai/models) — routing, fallback, and pricing all follow OpenRouter's own rules from there.
