Issue #9 | April 22, 2026
TL;DR
- Claude Opus 4.7 is GA with 13% coding benchmark lift and the first production model with real-time cyber safeguards. Differential capability reduction from Mythos is now shipping. Same $5/$25 pricing.
- Vercel got breached through an AI tool's OAuth scope. An attacker pivoted from Context.ai's OAuth app to enumerate environment variables. ShinyHunters claims to be selling the data. The AI supply chain attack vector everyone warned about just happened.
- Spring AI SDK for Bedrock AgentCore hits GA. Java developers get first-class agent infrastructure on AWS with Spring patterns, pay-per-use pricing, and zero idle compute.

Claude Opus 4.7: Cyber Safeguards Ship to Production
Anthropic released Opus 4.7 this week. The coding benchmarks improved 13% over 4.6. Vision got better. But the real story is what the model won't do.
Opus 4.7 is the first production model with differential capability reduction. The technique came from Mythos (leaked in Issue #6). During training, Anthropic selectively reduced the model's ability to perform prohibited security operations while preserving legitimate coding and analysis capabilities.
