+of Singapore's local accents and dialects.
 
+MERaLiON stands for <i>Multimodal Empathetic Reasoning and Learning in One Network</i>.

-### Model Description
+## Model Description
 
-<!-- Provide a longer summary of what this model is. -->
+MERaLiON-AudioLLM is designed to take in an audio-text pair as
+input and generates a text output.
 
-This is the model card of a 🤗 transformers model that has been pushed on the Hub. This model card has been automatically generated.
+The architecture comprises three key components: an audio encoder that transforms speech or audio inputs into sequences of vector representations, a text decoder that interprets and responds to natural language instructions, and an adaptor module that compresses the encoder representations while aligning the encoder’s hidden dimension with the text decoder’s embedding size.

-## Evaluation
+MERaLiON-AudioLLM is trained on a diverse collection of publicly available datasets, alongside synthesised and augmented samples carefully curated by the team and native speakers, totaling 260,000 hours of audio.
 
-<!-- This section describes the evaluation protocols and provides the results. -->
+### Compute and Infrastructure
 
-### Testing Data, Factors & Metrics
+MERaLiON-AudioLLM is trained on the ASPIRE 2A+ Supercomputer Cluster, provided by the National Supercomputing Centre (NSCC). ASPIRE 2A+ cluster provides multiple H100 nodes, with each compute node equipped with 8 Nvidia H100 GPUs, 2 TB of RAM, and 30 TB of locally attached NVMe storage. These nodes are interconnected via a rail-optimised, full fat-tree topology, utilising 400 Gb/s NDR InfiniBand cables. Additionally, the cluster incorporates a 2.5 PB SSD-based Lustre file system, linked to the H100 nodes through high-speed InfiniBand connections. 
 
-#### Testing Data
+With a global batch size of 640, we train the current release of MERaLiON-AudioLLM for around 200k steps, which took 2 days to complete using 16 nodes, 128 H100 GPUs.
