Anthropic opened a new front beyond the export-control saga with Claude Science, a dedicated research workbench that wires Claude into 60-plus genomics, proteomics, and cheminformatics databases and marks its own entry into drug discovery — Novo Nordisk and the Allen Institute among early users, up to $30K in research credits on offer — while a High-severity token-exfiltration CVE (CVE-2026-50143) in the widely used Apify MCP server landed in the same window.

Anthropic's 19-day frontier blackout ended: after Commerce lifted the June 12 export controls on June 30, Fable 5 and Mythos 5 came back on July 1 — Fable 5 redeployed across Claude.ai, the Claude Platform, Claude Code, and Cowork behind a new, tighter cybersecurity classifier and a temporary 50%-of-limit cap through July 7 — landing the same week Anthropic shipped Claude Sonnet 5, a 1M-context mid-tier model priced at $2/$10 that closes much of the agentic-coding gap to Opus 4.8.

AI News — July 1, 2026
The export-control blackout that darkened Anthropic's frontier models for 18 days is over: on June 30 the Commerce Department lifted its June 12 directive on Fable 5 and Mythos 5 after Anthropic agreed to proactively detect security risks, coordinate future releases with the government, and report malicious activity — and Anthropic says it begins restoring Fable 5 globally on July 1.

A wave of independent benchmarks this week put Zhipu's freely downloadable, MIT-licensed GLM-5.2 at or near restricted US frontier models on cybersecurity work — the exact capability the June 12 Fable 5 / Mythos 5 export ban was meant to contain — with CNBC clocking it within a point of Opus 4.8 on agentic tasks at roughly a fifth of the cost, the first concrete sign that API-level export controls can't hold a capability once an open-weight model reaches it.

AI News — June 27, 2026
On June 26 the US government drew a line around who may use the most capable models, twice in one day: it cleared Anthropic's Mythos 5 — its strongest cybersecurity model — for redeployment to roughly 100 US critical-infrastructure defenders (while leaving Fable 5 dark, 15 days on), and hours earlier OpenAI previewed its new GPT-5.6 family (Sol, Terra, Luna) only to about 20 government-vetted partners, saying such restrictions "shouldn't be the norm" — two state-gated frontier rollouts in a single day.

Anthropic told US senators and the White House that operators tied to Alibaba's Qwen lab ran the largest distillation attack it has seen — 28.8 million exchanges through roughly 25,000 fraudulent accounts between April 22 and June 5, aimed squarely at Claude's software-engineering and agentic-reasoning capabilities — turning the US–China model fight from export bans on Anthropic's own frontier models toward a charge that a rival is siphoning them through the front door.

A viral Senate-hearing quote recast why Washington pulled Mythos — Sen. Mark Warner relayed that the NSA's own chief told him the model broke into "almost all" of the agency's classified systems in hours during a red-team test, a line The Economist's author and a dissenting executive both warned against reading literally — landing on the day Fable 5's no-extra-cost window on Pro/Max/Team/Enterprise closes, with the model still dark and usage-credit metering set to begin tomorrow.

AI News — June 19, 2026
The Fable 5 blackout edged toward a thaw — Anthropic's international chief told a Seoul office launch the models will be back "in coming days," and Fortune reports the company and the White House are negotiating a deal that would jointly define when a jailbreak is dangerous enough to pull a model — while Claude Code shipped Artifacts, a beta turning a coding session into a live, shareable dashboard.

AI News — June 17, 2026
The White House gave its own account of the Fable 5 shutdown — David Sacks said Anthropic was warned a China-tied entity had reached Mythos and "refused to fix" the jailbreak, so "the ball is in Anthropic's court" — while Anthropic denies Chinese access was ever raised and prediction-market traders bet the models are back within weeks.

AI News — June 16, 2026
The technique behind the Fable 5 export ban turned out to be the prompt "fix this code" — Amazon's finding, not a jailbreak — as cybersecurity experts signed an open letter to rescind the controls and Anthropic met administration officials Monday to argue its case, with both models still dark.

AI News — June 14, 2026
A US government export-control directive forced Anthropic to suspend all access to Fable 5 and Mythos 5 — three days after Fable 5's launch — pulling the SWE-bench-leading model from the API and every Claude plan over a disputed jailbreak claim.
