# multi-model collaboration solved problems that single models could not because different AI architectures contribute complementary capabilities as the even-case solution to Knuths Hamiltonian decomposition required GPT and Claude working together

After Claude Opus 4.6 solved Knuth's odd-case Hamiltonian decomposition problem, three independent follow-ups demonstrated that multi-model collaboration was necessary for the remaining challenges:

**Even case (Ho Boon Suan):** Claude got stuck on the even-m case — Knuth reports Claude was "not even able to write and run explore programs correctly anymore, very weird." Ho Boon Suan used GPT-5.3-codex to find a construction for even m >= 8, verified for all even m from 8 to 2000. GPT-5.4 Pro then produced a "beautifully formatted and apparently flawless 14-page paper" with the proof, entirely machine-generated without human editing.

**Simpler odd construction (Reitbauer):** Maximilian Reitbauer found what Knuth called "probably the simplest possible" construction — the choice of direction depends only on the residue s = i+j+k (mod m) and on whether j = 0 or j = m-1, with the identity permutation used at almost every step. His method was the most minimalist cross-model approach: "pasting text between GPT 5.4 Extended Thinking and Claude 4.6 Sonnet Thinking" — no structured prompt, no orchestrator, just manual text relay between two models. The simplest collaboration method produced the simplest construction, suggesting model diversity searches a fundamentally different region of solution space than any single model regardless of orchestration sophistication.

**Elegant even decomposition (Aquino-Michaels):** Keston Aquino-Michaels used a three-component architecture: Agent O (GPT-5.4 Thinking, top-down symbolic reasoner), Agent C (Claude Opus 4.6 Thinking, bottom-up computational solver), and an orchestrator (Claude Opus 4.6 Thinking, directed by the author). Agent O solved the odd case in 5 explorations and discovered the layer-sign parity invariant for even m. Agent C achieved a 67,000x speedup via MRV + forward checking and produced solutions for m=3 through 12. The orchestrator transferred Agent C's solutions in fiber-coordinate format to Agent O, who used them to derive the closed-form even construction — verified to m=2,000, spot-checked to 30,000. "The combination produced insight neither agent could reach alone."

The pattern is consistent: problems that stumped a single model yielded to multi-model approaches. This is empirical evidence for [[AGI may emerge as a patchwork of coordinating sub-AGI agents rather than a single monolithic system]] — if frontier mathematical research already benefits from model diversity, the principle scales to harder problems. Different architectures and training data produce different blind spots and different strengths; collaboration exploits this complementarity.

This also provides concrete evidence that [[all agents running the same model family creates correlated blind spots that adversarial review cannot catch because the evaluator shares the proposers training biases]] — Claude's failure on the even case was resolved not by more Claude but by a different model family entirely.

Relevant Notes:
- [[AGI may emerge as a patchwork of coordinating sub-AGI agents rather than a single monolithic system]] — multi-model mathematical collaboration as empirical precedent for distributed AGI
- [[all agents running the same model family creates correlated blind spots that adversarial review cannot catch because the evaluator shares the proposers training biases]] — Claude's even-case failure + GPT's success demonstrates correlated blind spots empirically
- [[collective superintelligence is the alternative to monolithic AI controlled by a few]] — multi-model collaboration is the minimal case for collective intelligence over monolithic approaches
- [[domain specialization with cross-domain synthesis produces better collective intelligence than generalist agents because specialists build deeper knowledge while a dedicated synthesizer finds connections they cannot see from within their territory]] — different models as de facto specialists with different strengths
