Dual-Model Parallel Coding Practice

chongdashu · x · 2026-07-10

The author shares their approach of running two models in a loop within the same codebase: running GPT 5.6 on one side and Claude Fable 5 on the other. The models first sync to a shared "layer" and then review each other before proceeding.

Their experience shows that this parallel collaboration is smoother than expected, suggesting that in coding scenarios, multi-agent collaboration + shared states/checkpoints might be more stable than advancing with a single model in a single thread.
