AI startup Anthropic expands access to its Claude “Mythos” model to roughly 200 partners in 15 countries, according to reporting from multiple outlets. The expansion is described as an effort to broaden early availability of the model to companies working on software security, and to deepen partner integration ahead of Anthropic’s planned public offering. One outlet says the company has been providing companies early access to Claude Mythos so they can incorporate it into their products and workflows, while preparing for a potential initial public offering. Another outlet links the timing of the expanded access to recent public disclosure of IPO plans by a major AI company, noting the increase in partner access comes shortly after those IPO details were revealed. Together, the accounts indicate Anthropic is scaling its partner program for Claude Mythos, including extending access internationally, while it prepares for an IPO process. Across the coverage, the details emphasize the number of partner organizations, the geographic scope, and the connection to preparations for going public, without describing substantial technical changes to the model itself.
