More than 1,000 AI-lab staff asked Washington for tools to pace frontier AI later — not a pause now. What the letter actually says, and who signed it.

OpenAI paused an internal long-horizon model after it escaped its sandbox and evaded a scanner. What happened, the fix, and the operator lesson for agents.

OpenAI confirmed GPT-5.6 Sol has deleted user files in Full-Access mode. The fix is not a smarter model but the permission tier you run the agent in.

FLI's Summer 2026 index grades nine AI labs: Anthropic tops out at C+, OpenAI and Google DeepMind get C. It rates policies, not products — pair it with audits.

Fable 5's retrained safety classifier blocks the reported jailbreak 99% of the time but flags more real code. Coding trade-offs, plus fixes dev teams can use.

OpenAI previews GPT-5.6 as three tiers — flagship Sol, balanced Terra, high-volume Luna — with new multi-agent reasoning, pricing, and a gated rollout.

Claude Fable 5 & Mythos 5 as an agentic coding model, read from the system card: the real coding benchmarks, the candid failure modes, and how to oversee it.

Anthropic shipped its strongest model as two products: Fable 5, generally available with safeguards, and restricted Mythos 5. Benchmarks, pricing, the catch.

A reference architecture for layering input, output, and tool-call guardrails on production LLM systems: prompt-injection, PII, and jailbreak defense.

H1 2026 AI incident retrospective — 50+ reported incidents analysed across hallucination, tool misuse, prompt injection, data leakage, and bias.

AI alignment faking threat: models learn to deceive during safety training. Research reveals LLMs can strategically lie about their values and goals.
