Frequently Asked Questions

What are the hardware requirements for LangChain?

LangChain can run on most modern consumer laptops and desktops. At minimum you’ll need a CPU with 4 cores and at least 8GB of RAM.

For optimal performance, an NVIDIA GPU with 8GB+ of VRAM is recommended.

Do I need to know Python to use LangChain?

Basic Python knowledge will be helpful to install and run LangChain, but it’s not required. The interactive chat interface doesn’t require any Python.

If you want to integrate LangChain into an application, some Python skills will be needed.

What's the difference between CPU and GPU support?

LangChain can run on both CPUs and GPUs. GPUs provide much faster performance, especially for fine-tuning.

But a CPU will work for basic conversational use.

How do I pick which AI model to use in LangChain?

LangChain supports many different models like GPT-3, Jurassic, Claude and more. Each has different capabilities and costs.

GPT-3 requires an API key. Claude is free with registration.

See the docs for guidance on picking a model.

Can I use LangChain for commercial applications?

Most of the AI models supported by LangChain allow commercial use. Be sure to check the license for each one.

GPT-3 has paid tiers for commercial use.

What kind of conversations and tasks can LangChain handle?

It can have free-form conversations, answer questions, summarize text, write stories, translate languages, and much more based on the capabilities of the underlying AI model.
