Show HN: Splice – CAD for Cable Harnesses and Electrical Assemblies

I first posted Splice CAD as an in-browser tool for making cable harnesses.

Since then it’s grown in both features and scope — the direction is moving from “harness-only” toward a lightweight CAD for wiring and electrical assemblies. New functionality includes:

Editing Enhancements

- Full undo/redo to easily restore editor state

- Multi-select & group actions to move, delete, and add components

- Bulk connect tool to create straight-through, crossover, or custom wiring patterns quickly

- Multiple connections per pin allow for daisy chains, etc.

Documentation Additions

- Multi-page PDF configurator to add A2, A3, or A4 pages for engineering drawing downloads

- WireViz YAML export (generate WireViz diagrams directly: https://www.danielrojas.net/projects/wireviz)

Library and Component Additions

- Expanded beyond harnesses to include categories for more applications: connectors, cables, breakers, fuses, switches, motors, power supplies

- Magic MPN button in the Component Creator to auto-fill specs from part numbers

From GPT-4 to GPT-5: Measuring Progress in Medical Language Understanding [pdf]

I recently worked on running a thorough healthcare eval on GPT-5. The results show a (slight) regression in GPT-5 performance compared to GPT-4 era models.

I found this to be an interesting find
