Why Build Your Own Language Models

You may better connect your LLM with particular use cases by incorporating domain-specific knowledge by pre-training and fine-tuning it. With this method, businesses may customize the model’s architecture and training procedure to fit their particular needs, striking a balance between scalability and specialization that may not be possible with off-the-shelf models. The ability to pre-train LLMs opens up hitherto unheard-of possibilities for innovation and product differentiation across sectors, especially as the need for personalized AI solutions keeps rising.

On a cluster of AMD Instinct MI250 GPUs, the AMD OLMo in-house trained series of language models (LMs) are 1 billion parameter LMs that were trained from scratch utilizing billions of tokens. In keeping with the objective of promoting accessible AI research, AMD has made the checkpoints for the first set of AMD OLMo models available and open-sourced all of its training information.

This project enables a broad community of academics, developers, and consumers to investigate, use, and train cutting-edge big language models. AMD wants to show off its ability to run large-scale multi-node LM training jobs with trillions of tokens and achieve better reasoning and instruction-following performance than other fully open LMs of a similar size by showcasing AMD Instinct GPUs’ capabilities in demanding AI workloads.

Furthermore, the community may use the AMD Ryzen AI Software to run such models on AMD Ryzen AI PCs with Neural Processing Units (NPUs), allowing for simpler local access without privacy issues, effective AI inference, and reduced power consumption.

Unveiling AMD OLMo Language Models

AMD OLMo is a set of 1 billion parameter language models that have been pre-trained on 16 nodes with four (4) AMD Instinct MI250 GPUs and 1.3 trillion tokens. It are making available three (3) checkpoints that correlate to the different training phases, along with comprehensive reproduction instructions:

  • AMD OLMo 1B: Pre-trained on 1.3 trillion tokens from a subset of Dolma v1.7.
  • Supervised fine-tuning (SFT) was performed on the Tulu V2 dataset in the first phase of AMD OLMo 1B, followed by the OpenHermes-2.5, WebInstructSub, and Code-Feedback datasets in the second phase.
  • AMD OLMo 1B SFT DPO: Using the UltraFeedback dataset and Direct Preference Optimization (DPO), this model is in line with human preferences.

With a few significant exceptions, AMD OLMo 1B is based on the model architecture and training configuration of the completely open source 1 billion version of OLMo. In order to improve performance in general reasoning, instruction-following, and chat capabilities, we pre-train using fewer than half of the tokens used for OLMo-1B (effectively halving the compute budget while maintaining comparable performance) and perform post-training, which consists of a two-phase SFT and DPO alignment (OLMo-1B does not carry out any post-training steps).

It generate a data mix of various and high-quality publically accessible instructional datasets for the two-phase SFT. All things considered, it training recipe contributes to the development of a number of models that outperform other comparable completely open-source models trained on publicly accessible data across a range of benchmarks.

Stage 1: Pre-training

In order to educate the model to learn the language structure and acquire broad world knowledge via next-token prediction tasks, the pre-training phase included training on a large corpus of general-purpose text data. To selected 1.3 trillion tokens from the Dolma v1.7 dataset, which is openly accessible.

Stage 2: Supervised Fine-tuning (SFT)

In order to give its model the ability to follow instructions, to then improved the previously trained model using instructional datasets. There are two stages in this stage:

Stage 1: To start, it refine the model using the TuluV2 dataset, a high-quality instruction dataset of 0.66 billion tokens that is made publicly accessible.

Stage 2: To refine the model using a comparatively bigger instruction dataset, Open Hermes 2.5, in order to significantly enhance the instruction following capabilities. The Code-Feedback and WebInstructSub datasets are also used in this phase to enhance the model’s performance in the areas of coding, science, and mathematical problem solving. The total number of tokens in these databases is around 7 billion.

Throughout the two rounds, it carried out several fine-tuning tests with various dataset orderings and discovered that the above sequencing was most beneficial. To lay a solid foundation, the employ a relatively small but high-quality dataset in Stage 1. In Stage 2, it use a larger and more varied dataset combination to further enhance the model’s capabilities.

Stage 3: Alignment

Finally, it use the UltraFeedback dataset, a large-scale, fine-grained, and varied preference dataset, to further fine-tune it SFT model using Direct Preference Optimization (DPO). This improves model alignment and yields results that are in line with human tastes and values.

Results

It contrast AMD OLMo models with other completely open-source models of comparable scale that have made their training code, model weights, and data publicly available. TinyLLaMA-v1.1 (1.1B), MobiLLaMA-1B (1.2B), OLMo-1B-hf (1.2B), OLMo-1B-0724-hf (1.2B), and OpenELM-1_1B (1.1B) are the pre-trained baseline models that to utilized for comparison.
