The author benchmarks OpenAI's GPT-6.1 Sol against Anthropic's Claude Opus 5.5 across pricing, third-party coding benchmarks, and a 2026 cross-model review study. Sol costs half as much per token ($2/$10 per million input/output vs. $4/$20 for Opus) and scores competitively on Terminal-Bench (56.1% max vs. 59.6% for Opus) and DeepSWE (75.2% high setting). Opus leads on FrontierCode (54.4%) and in complex, long-duration tasks. A cited arXiv study found Claude reviewing Codex code boosted accuracy from 71.6% to 89.7%, but Codex reviewing Claude code reduced accuracy from 91.4% to 82.8%. The author proposes a baseline workflow: Sol handles design, implementation, and unit tests; Opus reviews for logic, security, and test gaps; Sol then revises and runs CI. For large systems, Opus leads architecture design. A token-cost estimate shows Sol+Opus review at $0.87 per task vs. $1.42 for Opus-only. Integration is feasible via GitHub Copilot's Rubber Duck, OpenAI's Codex plugin for Claude Code, or community MCP tools. The author stresses that review criteria, risk-based triggers, and human oversight remain essential.","keyPoints":["GPT-6.1 Sol costs half of Claude Opus 5.5 per token and scores 56.1% on Terminal-Bench max vs Opus 59.6%","Proposed workflow: Sol implements, Opus reviews, Sol revises — estimated 39% cheaper than Opus-only at $0.87 vs $1.42 per task"],"whyItMatters":"Shows a practical, cost-aware pattern for multi-model AI coding workflows that teams can adopt today using existing tooling like Copilot Rubber Duck and Codex plugins.","category":{"slug":"agents","name":"Agents & Tools","url":"https://digestai.news/category/agents"},"entities":{"companies":["OpenAI","Anthropic","GitHub"],"models":["GPT-6.1 Sol","Claude Opus 5.5","Claude Sonnet 4.6","GPT-5.4","Codex GPT-5.5","Claude Opus 4.7"],"people":[]},"firstPublishedAt":"2026-10-11T05:02:00Z","updatedAt":"2026-10-11T05:02:00Z","sourceCount":1,"hasPrimarySource":false,"sources":[{"outlet":"note.com","title":"Are 'Two Brains' Better Than 'One Ultimate Model' for Coding AI?
