- Title in English (translated by forck.live from zh): See and act, performance surpasses Jev: Shanghai AI Lab launches decision model 'Shusheng Mingjue', achieving dual upgrades in response efficiency and quality
- Subject: InternLM / 书生
- Models affected: Jev

Shanghai AI Lab released Intern-Decision (Shusheng Mingjue), a decision-making model that outperforms Jev and other open-source models on seven benchmarks, with three parameter sizes: 0.8B, 2B and 4B. The model integrates native visual perception with instruction following, enabling it to make decisions directly from visual input without separate image processing. On a single RTX 4090, the 0.8B and 2B models achieve about 30 decisions per second with roughly 33 ms latency, while the 4B model averages 44.16 ms — more than twice as fast as Jev's 109.70 ms. The 4B model scored 90.02 average across seven tasks, 1.28 points higher than Jev's 88.74, and topped the leaderboard. The team also explored a confidence-based routing mechanism where Intern-Decision handles routine judgments and passes uncertain cases to a larger model, cutting total task time by about 53% while losing only two correct answers.
