Abstract: We introduce Slam, a recipe for training high-quality Speech Language Models
(SLMs) on a single academic GPU in 24 hours. We do so through empirical
analysis of model initialisation and architecture, synthetic training data,
preference optimisation with synthetic data and tweaking all other components.
We empirically demonstrate that this training recipe also scales well with more
compute getting results on par with leading SLMs in a fraction of the compute
cost. We hope these insights will make SLM training and research more
accessible. In the context of SLM scaling laws, our results far outperform
predicted compute optimal performance, giving an optimistic view to SLM
feasibility. See code, data, models, samples at -
