# Best Practices

Most settings — like model architecture and GPU offloading — can be adjusted via your LLM providers like [LM Studio.](https://lmstudio.ai/)

**However, `max_tokens` and `context_window` should be set via Open Interpreter.**

For local mode, smaller context windows will use less RAM, so we recommend trying a much shorter window (\~1000) if it's is failing or if it's slow.

<CodeGroup>
  ```bash Terminal theme={null}
  interpreter --local --max_tokens 1000 --context_window 3000
  ```

  ```python Python theme={null}
  from interpreter import interpreter

  interpreter.offline = True # Disables online features like Open Procedures
  interpreter.llm.model = "openai/x" # Tells OI to send messages in OpenAI's format
  interpreter.llm.api_key = "fake_key" # LiteLLM, which we use to talk to LM Studio, requires this
  interpreter.llm.api_base = "http://localhost:1234/v1" # Point this at any OpenAI compatible server

  interpreter.llm.max_tokens = 1000
  interpreter.llm.context_window = 3000

  interpreter.chat()
  ```
</CodeGroup>

<Info>Make sure `max_tokens` is less than `context_window`.</Info>
