PrismaCoder: Pushing the Boundaries of Open Multimodal Code Intelligence through Decomposed Rubric Synthesis

Multimodal code intelligence connects the symbolic world of programs with the visual world their execution creates.

Key points

  • The same rubric serves as both filter and reward: it curates the supervised corpus, then drives reinforcement learning on visual-coding tasks.
  • Leveraging PrismaForge for data synthesis and filtering, we build PrismaCoder-2M, the most diverse open dataset for multimodal code intelligence and the largest to date.
  • On the model side, we train PrismaCoder-9B and PrismaCoder-35B on this data and release both.
  • Our analyses further show that the proposed rubric-based pipeline improves multimodal coding performance across model backbones.
