Agents Hit 23% on Hard Tasks, CLIP's Three-Year Path Dependency

  • Error-Driven Chain-of-Thought Synthesis Fills the Industrial Code Reasoning Data Gap. InCoder generates reasoning traces through multi-turn error feedback interaction — a data strategy transferable to any vertical domain lacking public expert data.
  • CLIP's Single Encoder Has Dominated VLMs for Three Years, Possibly Just Path Dependency. CoME-VL fuses contrastive and self-supervised encoders, lifting grounding tasks by 5.4%. Ablation experiments reveal the scaling boundaries of multi-encoder fusion.
  • "Called a Tool" Does Not Mean "Tool Helped." Agentic-MME audits tool use across three layers. The strongest model hits only 23% on the hardest tasks, with many calls being ineffective actions.
  • RAG's Enterprise Bottleneck Goes Far Beyond Retrieval Accuracy. Document structure, reasoning chains, and explainability are independent failure dimensions. A four-axis diagnostic framework guides optimization better than leaderboard scores.
