OpenAI's ChatGPT, while popular, isn't open-source and has usage restrictions. Several open-source alternatives have emerged, such as BLOOM, LLaMA, Vicuna, Dolly, StableLM, MPT-7B, and StarCoder. These models vary in size and licensing, but they offer more accessibility and potential for local use. Projects like Open Assistant aim to develop language models that can run on consumer hardware. Tools like llama.cpp and web-based interfaces facilitate running these models locally, providing a ChatGPT-like experience.
