¿Sonnet 4.7? Al parecer Anthropic se lo salta y va directo a Sonnet 4.8 para junio. Filtración brutal: 98% de precisión visual en UI, razonamiento 'X High' y tokenizador 30% mayor.
¡Se viene fuerte! 👇
Claude Sonnet 4.8 Leaks
- Anthropic accidentally shipped a massive 512,000-line internal debugging source map through a Claude Code npm update on March 31, 2026
- The leaked source code references Sonnet 4.8 inside unreleased keyword filters, strongly suggesting Anthropic is skipping Sonnet 4.7 entirely
- Sonnet 4.8 is expected to inherit vision upgrades from Opus 4.7, reportedly pushing visual accuracy above 98% for UI mockups and messy architecture diagrams
- A major coding boost with cleaner one pass completions and much more literal instruction following
- A new "X high" reasoning effort tier may also be coming for stronger logic without extremely long generation times
Updated tokenizer may use 30% more tokens on the same prompts compared to older Sonnet versions
- Currently expected around mid to late June
