#### OpenAI JS SDK
- OpenAI JS SDK does not support setting context window size, however this can be set for Ollama by passing `num_ctx` directly with a `@ts-expect-error` as an undocumented parameter in the [OpenAI JS SDK](https://github.com/openai/openai-node?tab=readme-ov-file#making-customundocumented-requests)
#### OpenAI JavaScript library
- OpenAI JavaScript library does not support setting context window size, however this can be set for Ollama by passing `num_ctx` directly with a `@ts-expect-error` as an undocumented parameter in the OpenAI JavaScript library. [See documentation here](https://github.com/openai/openai-node?tab=readme-ov-file#making-customundocumented-requests)
