Anthropic offers Claude Science, a specialized research environment with 60+ databases, and provides Claude Sonnet 5 as a cost-effective model with autonomous agent capabilities.
Following export controls due to security concerns in vulnerability identification, Claude Fable 5 will be released globally starting July 1, 2025, with newly assessed safeguards.
The US government blocks two high-performance Anthropic AI models for foreign nationals over concerns about a workaround to security restrictions — a step Anthropic criticizes as non-transparent and technically unjustified.
Anthropic increasingly differentiates AI access by user category: the public receives Fable 5 with active security routing, while governments, large enterprises and research labs can use the less restrictive Mythos 5.
Anthropic splits Claude Fable 5 into a public version (with safeguards) and a restrictive version (Claude Mythos 5 without security layers) for verified cybersecurity experts.
