New Delhi,18 June 2022: More recently, the biggest news is that Anthropic’s advanced Mythos 5 and Fable 5 models were taken offline or had access restricted after U.S. government concerns about potential misuse and security vulnerabilities. Negotiations between Anthropic and U.S. officials are ongoing.
Based on what Anthropic has publicly said and what has been reported, Claude Mythos 5 is described as their most capable model and is currently restricted because of its advanced cybersecurity and biology-related abilities.
Reported capabilities include:
Advanced software engineering: handling very large codebases, complex debugging, code migration, and long-running programming tasks.
Cybersecurity research: identifying software vulnerabilities, analyzing exploit chains, and helping secure critical systems. Anthropic says Project Glasswing participants used Mythos-class models to find thousands of serious vulnerabilities.
Scientific reasoning: stronger performance in scientific research, healthcare, and biology-related tasks than previous Claude models.
Long-horizon reasoning: better at completing complex, multi-step tasks that require maintaining context over long periods.
Vision and knowledge work: stronger document analysis, research synthesis, and multimodal understanding.
Anthropic has specifically stated that some Mythos-level capabilities could be misused in cybersecurity and biology, which is why access is restricted and why the public-facing version (Fable 5) automatically falls back to a less capable model for certain sensitive topics.
When Anthropic talks about “sensitive topics,” they’re generally referring to areas where a very capable AI could potentially help someone do harm if misused.
The main categories repeatedly mentioned are:
1. Cyber security
Finding software vulnerabilities
Developing exploits
Automating hacking workflows
Analyzing critical infrastructure weaknesses
2. Biology
Advanced biological research that could potentially be misused
Topics related to pathogens or biological hazards
Research that might help create dangerous biological agents
3. Chemistry
Certain chemistry knowledge that could be applied to creating hazardous substances
Research areas with dual-use (beneficial and harmful) potential
Some reports also indicate Anthropic added restrictions around frontier AI development itself, limiting assistance that could accelerate the creation of highly capable competing AI systems.
In fact, job disruption is one of the risks that Anthropic’s CEO, Dario Amodei, talks about most often.
He has repeatedly warned that AI could eliminate a large share of entry-level white-collar work in areas such as software engineering, finance, law, consulting, customer support, and administrative work. He has suggested unemployment could rise significantly if society does not adapt quickly.
More recently, he argued that software itself may become extremely cheap because AI can generate custom applications on demand, potentially disrupting the traditional software industry and changing what software engineers do for a living.
That said, there is a major debate within the industry:
Some AI leaders believe AI will replace many jobs and create substantial unemployment.
Others, including some technology executives, argue that AI will mainly automate tasks rather than entire occupations, creating new roles while changing existing ones.
Current research suggests that what is happening so far is often job redesign rather than complete job elimination. Companies are changing job requirements, workflows, and hiring patterns as AI tools become more capable.
