Python Code : GPT-J 6B

You possibly can refer the colab pocket book for making an attempt it out.

Python code for GPT-J 6B is just like the code for Cerebras-GPT. The one change is the initialisation of the bottom mannequin BaseModel.create("gptj_lora_int8") as an alternative of BaseModel.create("cerebras_lora_int8")

OpenChatKit Mannequin

Introduction : OpenChatKit

OpenChatKit is an open-source massive language mannequin for creating chatbots, developed by Collectively. They collaborated with LAION and Ontocord to create the coaching dataset. It comes underneath an Apache-2.0 license, with full entry to supply code, mannequin weights, and coaching datasets. The goal of the challenge is to advertise inclusivity, transparency, and robustness in open-source basis fashions. It’s good at performing numerous duties together with summarization and query answering inside context, info extraction, and textual content classification.

It has 20 billion parameters skilled on 43 million directions sized coaching dataset. It’s known as GPT-NeoXT-Chat-Base-20B It additionally has yet one more mannequin based mostly on ElutherAI’s Pythia-7B mannequin known as Pythia-Chat-Base-7B which is a 7B parameter language mannequin.
