GPT-NeoX

GPT-NeoX is a family of open large language models from EleutherAI, developed as a flexible alternative to commercial LLMs with an emphasis on scalability and deployment within one’s own infrastructure. The base GPT-NeoX-20B model contains around 20 billion parameters and is trained on The Pile corpus, comprising hundreds of gigabytes of text, which gives it strong capabilities for generating coherent text, code, and analytical responses. The decoder-only Transformer architecture makes the model compatible with familiar frameworks (Hugging Face, DeepSpeed, etc.) and allows training and inference to be efficiently parallelized across GPU clusters. Technically, GPT-NeoX supports long context windows (several thousand tokens), various fine-tuning methods (instruction tuning, LoRA, PEFT), and can be easily integrated into RAG pipelines and agent-based systems. GPT-NeoX can be used to develop enterprise chatbots and assistants, intelligent search across internal documents, report and analytics generators, code copilots for developers, and also to embed models directly into B2B and B2C products: SaaS services, marketplaces, financial platforms, and more. The FreeBlock team handles the full cycle of work: selecting and deploying the appropriate version of GPT-NeoX, fine-tuning it on your company’s data, designing the architecture (RAG, agents, integrations with CRM/ERP/DWH), and bringing the solution into reliable production.
