LongCat-DeepResearch is a deep research system that combines an enhanced LongCat model with a multi-agent workflow for producing comprehensive, evidence-grounded reports, achieving competitive scores on benchmarks like DeepResearchBench and ResearchRubrics.
Introduces SBCO, a self-supervised verifier-grounded harness optimizer for planning agents that improves agent outputs via approximate block coordinate ascent, matching or exceeding self-modifying baselines with far less compute.
