InternLM open-sources Intern-Decision: 4B multimodal model beats Jev 1.13.0

The InternLM team released Intern-Decision, a multimodal decision model family in 0.8B/2B/4B sizes, open on Hugging Face and GitHub. The 4B model outperforms Jev 1.13.0 in their tests.

On a single RTX 4090, local deployment reaches 30 FPS decision calls, opening room for real-time applications. The team also built a calibration benchmark using classic probability problems (dice rolls, Monty Hall): Jev's decision model turns out to be poorly calibrated, while Intern-Decision's predicted distributions stay closer to the golden distribution.
