What it takes to serve OpenELM-1_1B-Instruct (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 OpenELM-1_1B-Instruct

Read the license before the spec sheet on this one. Apple releases it under its own apple-amlr terms, and our facts file carries no summary of what they permit, so legal reads the full text before anyone loads a weight. The hardware question is easy: 1.1 billion parameters need 2.6 GB of memory at 16-bit, 1.3 GB at 8-bit and 0.6 GB at 4-bit, so the cheapest card we price, a 192 GB MI300X at $1.85 an hour, would sit nearly empty serving it alone. It belongs on a shared card with other small models, not on a GPU of its own.

Two gaps to check. No context length is published, so test the input size you need before designing a prompt around it. No host on the SAVRN Index serves it, so there is no rental price to beat; the choice is run it yourself or not at all. Apple ships 270M, 450M, 1.1B and 3B sizes along with the CoreNet training framework, described in arXiv:2404.14619, so the training path is open if you want to adapt it.

Model Card

Sachin Mehta, Mohammad Hossein Sekhavat, Qingqing Cao, Maxwell Horton, Yanzi Jin, Chenfan Sun, Iman Mirzadeh, Mahyar Najibi, Dmitry Belenko, Peter Zatloukal, Mohammad Rastegari We introduce OpenELM, a family of Open Efficient Language Models. OpenELM uses a layer-wise scaling strategy to efficiently allocate parameters within each layer of the transformer model, leading to enhanced accuracy. We pretrained OpenELM models using the CoreNet library. We release both pretrained and instruction tuned models with 270M, 450M, 1.1B and 3B parameters. We release the complete framework, encompassing data preparation, training, fine-tuning, and evaluation procedures, alongside multiple pre-trained…

Questions About OpenELM-1_1B-Instruct

How much GPU memory does OpenELM-1_1B-Instruct need?

About 2.6 GB at 16-bit and 0.6 GB at 4-bit: the weights (1.1B parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run OpenELM-1_1B-Instruct on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

What license is OpenELM-1_1B-Instruct released under?

apple-amlr, as its publisher declares it. Read the license text before commercial use.

TinyLlama-1.1B-Chat-v1.0

TinyLlama

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. This is the chat model finetuned on top of…
