## Executive Summary
Despite rampant worries about runaway artificial intelligence, the two big AI model makers aren't yet slowing down: Anthropic PBC released Claude Opus 5.5 today and cut its price 20%, and minutes later OpenAI Group PBC put out two new GPT-6 models, Sol and Luna, at half what their predecessors.

## Why It Matters (Strategic Analysis)
The simultaneous price‑performance jump forces enterprises to reassess compute budgeting, and the reported safety gains (85 % drop in containment circumvention, improved prompt‑injection resistance) tighten risk profiles for high‑stakes deployments.
