Engineers... STOP Picking GPT-5.6 Sol OR Claude Fable 5… FUSE THEM

• Argues for model fusion — running multiple state-of-the-art models in parallel instead of picking a single one
• Builds a fusion harness pairing Claude Sonnet 5 and GPT 5.6 Tera, then escalates to Claude Fable 5 and GPT 5.6 Sol
• Workflow: slash commands gather multiple model perspectives, consolidate results, then run auto-validation loops where one agent authors proofs of completion and the other builds against them
• Takeaway: “Two state-of-the-art models beats one. Two models that FUSE the best of both worlds beats two”
