Typed relationship
Choose langcorn if…
- License: langcorn is MIT, sglang is Apache-2.0.
- Both Langcorn and sgLang are focused on the deployment of large language models, but they approach it differently. While Langcorn is tailored specifically for LangChain models with FastAPI as a backend, sgLang is more generalized in its approach.
- Tags unique to langcorn: api, fastapi, langchain, large language models.
- When you are deploying applications built with Large Language Models (LLMs) like OpenAI.
When NOT to use langcorn
- When you require a framework other than FastAPI for your deployment needs.
- If you are looking for broader support beyond LangChain-compatible projects.
- In cases where minimal integration with the current infrastructure is not acceptable, as LangCorn requires specific adaptation steps.
Choose sglang if…
- License: sglang is Apache-2.0, langcorn is MIT.
- Both Langcorn and sgLang are focused on the deployment of large language models, but they approach it differently. While Langcorn is tailored specifically for LangChain models with FastAPI as a backend, sgLang is more generalized in its approach.
- Tags unique to sglang: attention, cuda, diffusion, inference.
- - When you need to deploy large language or multimodal models efficiently across various types including transformers and diffusion models.
When NOT to use sglang
- - Avoid using SGLang if your project or infrastructure already heavily relies on specific serving solutions that do not integrate easily with Python deployments.
- - If real-time performance is less critical than maintaining a lightweight and easy-to-deploy framework, another more specialized tool might be preferable.
- - For projects where the model types are limited to those beyond large language models (LLMs) or multimodal models, such as strictly CNNs or RNNs without a need for transformer support, SGLang may not
