Gains come from removing the causal attention mask and training on more data, including tasksource and Bespoke Nimble-derived datasets. The model card details its checkpoint format (a separate readout head rather than full vocabulary), noncausal attention requirements for correct inference, calibration temperature handling, image input processing with configurable resolution caps, and usage instructions requiring Python 3.12+, CUDA GPU with ~49 GiB memory, and the included inference code. ## Full article daily.dev links to this article rather than hosting it.
