TinyLlama-1.1B-Chat-v1.0

by TinyLlama TinyLlama/TinyLlama-1.1B-Chat-v1.0

https://github.com/jzhang38/TinyLlama The TinyLlama project aims to pretrain a 1.1B Llama model on 3 trillion tokens. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs.

What it takes to serve TinyLlama-1.1B-Chat-v1.0 (1.1B parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Sep 18, 2026.

SAVRN's Notes on TinyLlama-1.1B-Chat-v1.0

Where the whole 16-bit model fits in 2.6 GB, the hardware question flips from which accelerator to how many copies. The Index floor is one MI300X with 192 GB at $1.85 per hour; 8-bit needs 1.3 GB and 4-bit 0.7 GB. We read TinyLlama-1.1B-Chat-v1.0 as a chat model for tight footprints: 1.1 billion parameters, a 2,048-token window, and the same architecture and tokenizer as Llama 2, which the publisher says lets it drop into projects built around Llama.

Apache 2.0 permits commercial use, modification and redistribution, requires keeping notices and stating significant changes, and includes an express patent grant, so a fine-tuned derivative is straightforward to ship. Check the lineage before committing: the chat tuning traces to ultrachat_200k and ultrafeedback_binarized on top of SlimPajama-627B and starcoderdata, and the 2,048-token window rules out long-document work.

# TinyLlama-1.1B

https://github.com/jzhang38/TinyLlama

The TinyLlama project aims to pretrain a 1.1B Llama model on 3 trillion tokens. With some proper optimization, we can achieve this within a span of "just" 90 days using 16 A100-40G GPUs. The training has started on 2023-09-01.

We adopted exactly the same architecture and tokenizer as Llama 2. This means TinyLlama can be plugged and played in many open-source projects built upon Llama. Besides, TinyLlama is compact with only 1.1B parameters. This compactness allows it to cater to a multitude of applications demanding a restricted computation and memory footprint.
