# AI News Digest - 2026-06-27

1. OpenAI launched GPT-5.6 Sol as its new flagship model, reported to outperform Anthropic's Claude Mythos 5 on coding benchmarks, and released it under U.S. government‑imposed restricted access rules with approvals required on a "customer by customer" basis.

2. Epoch AI published the MirrorCode benchmark to test models' ability to reconstruct complete programs, and Claude Opus 4.7 led with a 56 percent solve rate, rebuilding a 16,000‑line toolkit in about 14 hours while models continued to fail the most complex tasks.

3. The Linux Foundation and roughly 20 tech companies, AI labs, and banks launched Akrites to identify and fix critical open‑source software vulnerabilities ahead of potential AI‑powered attacks.

4. Lindy, an AI startup, discontinued use of Anthropic's Claude in favor of Deepseek, reporting that the switch saved the company millions as AI costs exceeded personnel expenses.
