[AINews] Claude Opus 5.5, the new default model for AINews — and everybody cuts prices 40-50%

AI introduction

Anthropic released Claude Opus 5.5, the first model in the Claude 5.5 family, claiming it matches Fable 5.1 on most tasks, is about 30% faster than Opus 5, and 40% cheaper per task; token pricing dropped from $5/$25 to $4/$20, and it became the default model for Claude Code and the Claude app. OpenAI responded the same day with 50% price cuts on GPT-6 Sol and Luna.

Why it matters

The article compiles Opus 5.5 pricing, benchmarks, and controversies, including third-party teardowns showing the 40% discount does not hold at max effort.
