Anthropic Claude Opus 4.7 →

Opus 4.7 is the reference Soul in every arena configuration we publish. It pairs natively with Claude Code (Skeleton) for a +15 Precision synergy that no other (Soul, Skeleton) combination matches in 2026.

Weaknesses: cloud-only (no local Heart pairing), tokens/sec ceiling makes its Speed bar the shortest of its tier.
