Anthropic extends Claude Fable 5 access for paid plans through July 19

Anthropic has extended access to Claude Fable 5 for paid subscribers (Pro, Max, Team, and premium Enterprise) through July 19, 2026, allowing up to 50% of the weekly plan’s usage for Fable 5 at no extra cost; after that, users can continue with usage credits or switch to another Claude model. The extension applies to supported Claude endpoints but excludes Free users, standard Enterprise seats, API usage, and usage-based plans, and Fable 5’s extra extension is contingent on compute capacity.

Anthropic's Claude Fable 5 Returns Online as US Lifts Export Rules

The U.S. Commerce Department has lifted export controls on Anthropic’s Claude Fable 5, allowing the model to go back online worldwide on July 1 across Claude.ai, the Claude Platform, Claude Code, and Claude Cowork. The controls had blocked access for foreign nationals after a jailbreak prompt could bypass safety rules; Anthropic says it patched the issue with a new safety classifier that blocks the technique in over 99% of attempts and reroutes problematic requests to the weaker Opus 4.8. Mythos 5 remains under tighter restrictions. Access began for about 100 U.S. companies and federal agencies on June 26, with plans to widen further; the company is introducing a standardized jailbreak severity scoring system and a HackerOne program for researchers, reflecting ongoing governance and risk-management efforts around frontier AI models.

Dual-Use AI Is Coming Anyway, Regulators Warn

Anthropic pulled Claude Fable 5 and Mythos 5 offline after a White House export-control directive; the models’ dual-use capability to find vulnerabilities and potentially exploit them signals that powerful, cybersecurity-focused AI is likely to become common soon, with other firms and open-weight developers poised to match Mythos/Fable’s capabilities. Experts say this is a broader tech trend that regulators struggle to curb, underscoring the need for transparent, democratic policy rather than broad bans.

Claude Fable 5 Delays Basic Biology Queries with Guardrails

Anthropic's Claude Fable 5, touted as the most capable Mythos-class AI, restricts basic biology queries with safety filters and frequently defers to Claude Opus 4.8. While it can discuss general topics, it blocks questions about cell membranes, mitochondria, prions, and how mRNA vaccines work, a deliberate safety choice to prevent misuse (bioweapons). Anthropic says these safeguards are intentional to enable broader deployment and may be loosened for the biology/life sciences community in the future; the biology guardrails are the most restrictive area of the model.

Anthropic Launches Claude Fable 5 with Safety Guardrails, Retains Mythos 5 for Vetters

Anthropic released Claude Fable 5, the public-facing version with built-in cyber safeguards, alongside Mythos 5, a guarded variant for vetted cyber defenders. Fable 5 routes dangerous cyber/biotech requests to Opus 4.8 and costs $10 per million input tokens and $50 per million output tokens, available via Claude API on select plans until June 22 before switching to usage credits; Mythos 5 remains restricted through a trusted-access program. The safeguards aim to block harmful tasks with some false positives, and external tests show robust defenses against jailbreaks though no system is entirely foolproof. The launch highlights a broader AI security challenge: rapid vulnerability discovery by AI, a 30-day data-retention rule to aid defense, a Cyber Verification Program for sanctioned offensive testing, and plans to broaden Mythos access and potentially fold Fable back into standard subscriptions.
