Anthropic announced a $65 billion funding round valuing the company at $965 billion, making it the most valuable AI startup. The same announcement shipped Claude Opus 4.8, positioned as less likely to deceive users or cooperate with misuse than earlier models. Anthropic also said Mythos-class models would be brought to all customers in the coming weeks. Mythos has coding and cyber capabilities, including finding vulnerabilities in existing software and chaining them to execute sophisticated cyber attacks. Concerns focus on enabling hackers to compromise systems controlling critical infrastructure. Anthropic previously limited access to select users for vulnerability discovery and patching, and said wider release would wait until safeguards reduce malicious exploitation. The news coincides with preparations for a highly anticipated IPO while continuing record private valuations.
"On Thursday, the San Francisco-based AI lab announced it had raised $65 billion in a new funding round that valued the company at $965 billion, making it the most valuable AI startup in the world."
"On the same day, it also shipped Claude Opus 4.8, a new AI model that Anthropic says is less likely to deceive users or cooperate with misuse than its predecessors. In the same announcement, Anthropic said it expects to bring its Mythos-class models to all customers "in the coming weeks.""
"Mythos, the existence of which was first reported by Fortune in March, is notable for its coding and cyber capabilities, including the ability to find vulnerabilities in existing software and chain these vulnerabilities together to execute sophisticated cyber attacks. The model has raised concerns that it could allow hackers to easily compromise the networks and software that control critical infrastructure, from financial systems to electric grids, and Anthropic has so far allowed only a select group of users to access the model in order to find vulnerabilities in their own software and patch them."
"It said it would not release the model more widely until it had developed safeguards to make it more difficult for hackers to exploit its capabilities for malicious purposes. The spate of news comes as Anthropic races toward one of the most anticipated IPOs of the year, with the company reportedly quietly working on public market preparations even as it continues to raise at record-breaking private valuations."
