This means it's open-source, permitting use in multiple contexts like commercial projects without charge. ## Decision facts: gpt-neox - **Pricing:** freemium - Free to use with the caveat of adhering to the Apache License terms, particularly in preserving copyright and license headers for all derivations. - **Adopt for:** GPT-NeoX from EleutherAI leverages GPU-based model parallelism via Megatron and DeepSpeed libraries to facilitate the training of large-scale autoregressive transformers in Python, under an Apache-2.0 license. - **License detail:** The tool is licensed under Apache-2.0, allowing permissive use but emphasizing that derivative works must preserve copyright headers and licenses as per their origins ## Choose when ### Choose llmfit if… - llmfit is primarily Rust; gpt-neox is Python. - License: llmfit is MIT, gpt-neox is Apache-2.0. - Requirements: Min 4 GB RAM; Built for Rust environments; No explicit dependency on Docker or other container runtimes. - Tags unique to llmfit: gguf, llm, localai, mlx. - llmfit ships Docker support for self-hosted deployment. - - When you need to quickly identify compatible machine learning models for your specific hardware configuration without manual research. llmfit automates this process, making it efficient. ### Choose gpt-neox if… - gpt-neox is primarily Python; llmfit is Rust. - License: gpt-neox is Apache-2.0, llmfit is MIT. - Pricing: Free to use with the caveat of adhering to the Apache License terms, particularly in preserving copyright and license headers for all derivations.. - Tags unique to gpt-neox: deepspeed-library, gpt-3, language-model, transformers. - - When your project requires a framework based on state-of-the-art libraries like Megatron and DeepSpeed that are optimized for large GPU clusters. ## When NOT to use llmfit - - When the focus is on model development rather than discovery or management; llmfit centers on finding models based on hardware but does not provide deep integration into the training process itself. - - If real-time adaptability and dynamic hardware compatibility changes are needed, as llmfit operates with a more static approach tied to one command per execution. ## When NOT to use gpt-neox - - In scenarios where minimal hardware resources, such as a single low-memory GPU or CPU-only environments, are available for training due to GPT-NeoX's requirement for a large-scale infrastructure. - - If your project is limited by the Apache License terms or requires proprietary codebases without open-source contributions and modifications from external parties. ## Common questions ### What is the difference between llmfit and gpt-neox? llmfit: Hundreds of models & providers.
