- To enable multi-GPU data parallelism, add `--dp 2`. Data parallelism is better for throughput if there is enough memory. It can also be used together with tensor parallelism. The following command uses 4 GPUs in total. We recommend [SGLang Router](../router/router.md) for data parallelism.

This doc describes the sampling parameters of the SGLang Runtime. It is the low-level endpoint of the runtime.
If you want a high-level endpoint that can automatically handle chat templates, consider using the [OpenAI Compatible API](./openai_api_completions.ipynb).

## `/generate` Endpoint
The `/generate` endpoint accepts the following parameters in JSON format. For detailed usage, see the [native API doc](./native_api.ipynb). The object is defined at `io_struct.py::GenerateReqInput`. You can also read the source code to find more arguments and docs.

## General Code Style
- Avoid code duplication. If the same code snippet (more than 5 lines) appears multiple times, extract it into a shared function.
- Minimize device synchronization. Reduce expensive CPU-GPU synchronization operations, such as `tensor.item()` or `tensor.cpu()`, as much as possible. Use vectorized code instead.
- Keep files short. If a file exceeds 2,000 lines of code, please split it into multiple smaller files.

- Minimize device synchronization. Reduce expensive CPU-GPU synchronization operations, such as `tensor.item()` or `tensor.cpu()`, whenever possible. Use vectorized code.
- Keep files concise. If a file exceeds 2,000 lines of code, split it into multiple smaller files.
- Prioritize extreme efficiency. SGLang is a runtime, and most of your code runs on the critical path for every request. Optimize every minor overhead as much as possible.
