At the onset of the 20th century, electric cars powered by lead-acid batteries outnumbered gas-powered cars. The internal combustion engine ultimately won out, in part because those batteries had a range of just 30 miles. But Thomas Edison believed a nickel-iron battery could extend that range to as much as 100 miles, while also having a long life and recharging times of seven hours. An international team of scientists has revived Edison's concept of a nickel-iron battery and created their own version, according to a paper published in the journal Small.

Our model is trained with SFT, where reasoning samples include “…” sections with chain-of-thought reasoning before the final answer, covering domains like math and science. Non-reasoning samples are tagged to start with a “” token, signaling a direct response, and cover perception-focused tasks such as captioning, grounding, OCR, and simple VQA. Reasoning data comprises approximately 20% of the total mix. Starting from a reasoning-capable backbone means this data grounds existing reasoning in visual contexts rather than teaching it to reason from scratch.
