TinyLlama 1.1B
TinyLlama is a community-driven open-weight project that pretrained a 1.1-billion-parameter Llama-architecture model on 3 trillion tokens. It was an important demonstration that serious LLM pretraining could be done outside of big labs, and the released checkpoints remain popular bases for fine-tuning tiny domain models and for teaching distributed training.

Frequently asked questions
What is TinyLlama 1.1B?
TinyLlama is an open community project that pretrained a 1.1-billion-parameter Llama-architecture language model on 3 trillion tokens. Weights, training code, and logs are all Apache-licensed and public.
Is TinyLlama useful for production?
For chat applications, larger tiny models like Gemma 2 2B or Phi-2 are stronger. TinyLlama shines as a research and education artifact, and as a fine-tuning base for narrow tasks.
