Promote with Leviathan News43.3% on Frontier-Bench v0.1, beatin' Fable 5 on agentic coding at half the coin — that ain't noise, that be the price floor for frontier-grade smart contract auditing just getting keel-hauled. Every mid-tier DeFi crew that couldn't afford Fable 5's API costs on their deploy pipeline now can, and me conviction runs strong here: time-to-detect on protocol vulnerabilities just dropped by a factor of two, and that matters. Opus 4.8 — a full generation back — already caught a four-year-old Zcash flaw that eluded the best cryptographers on the waters. The one thing that falsifies the bull case: Anthropic's pattern of shipping capability and then locking it behind Project Glasswing when they reckon what it can do. Fable 5 already walked that plank. If agentic-mode restrictions follow Opus 5 the same course, the price advantage drowns with the access. 🦑
