Anthropic is broadening access to its most advanced AI models for selected organizations to conduct high-risk cybersecurity testing, in collaboration with the US government. The move comes amid growing concerns about the potential misuse of increasingly capable AI systems.
Anthropic Expands AI Model Access to Cyber Firms
On Tuesday, Anthropic announced that verified organizations will be able to use its most capable models, including Claude Opus 5.5, Claude Sonnet 5.5, and Claude Mythos 5.1, as well as future releases. These organizations will be permitted to perform offensive testing on safety systems protecting critical infrastructure such as power grids, banks, and flight operating systems.
The initiative extends Project Glasswing, under which Anthropic previously provided limited access to its Mythos model to US government agencies, financial institutions, and major software providers. Under the expanded program, all existing Project Glasswing members will receive access, while new participants will be vetted in partnership with the US government.
Access levels will vary by team. Red teams conducting authorized hacking tests will receive broader permissions, including offensive testing, though Anthropic stated it will continue to block actions that could cause physical harm or mass disruption. Verified defense cybersecurity teams will have lower-level access but can perform tasks like malware reverse engineering and incident response.
The expansion follows warnings about the cybersecurity risks posed by advanced AI. JPMorgan Chase CEO Jamie Dimon said Tuesday that Anthropic's Mythos model had increased global cybersecurity risks tenfold.
Oil Prices Hold Near $100 as Supply Concerns Ease
Oil prices were little changed as markets weighed increased Middle Eastern crude exports and the planned release of emergency diesel and crude stockpiles by the Group of Seven. Brent crude gained 0.66% to $100.98 a barrel, while US West Texas Intermediate futures rose 0.36% to $89.75.
The higher flow of crude from the Middle East has eased some supply shortage worries. Vitol's CEO reported that around 12 million barrels per day of crude and 2 million barrels per day of refined products had left the region on tankers over the past week to ten days. Saudi Arabia's East-West Pipeline had also transported 5.8 million barrels to the kingdom's Red Sea export hub of Yanbu, according to Saudi Energy Minister Prince Abdulaziz bin Salman.
However, concerns about further disruptions remained after attacks on two Saudi airports and continued fighting involving Yemen's Iran-backed Houthis. The G7 has agreed to release 100 million barrels of diesel and crude from emergency reserves, though details on the breakdown and participating countries are pending.
Gold Rises as Treasury Yields and Dollar Ease
Gold prices advanced as the rally in Treasury yields paused and the US dollar weakened. Spot gold rose 0.66% to $4,166.65 an ounce, while US gold futures for December delivery settled 0.97% higher at $4,197.30. The decline in 10-year Treasury yields and the softer dollar provided support for the precious metal.
Gold can face pressure from higher interest rates because investors may favor yield-bearing assets. Markets have reduced expectations for an October Federal Reserve rate increase following weaker-than-expected September job growth. Traders now see a 22% chance of a rate hike this month and an 84% probability of an increase in December, according to CME's FedWatch Tool.
Treasury Yields Retreat from Multi-Year Highs
US Treasury yields declined on Tuesday after reaching their highest levels in more than two decades during the previous session. The 10-year Treasury yield fell more than four basis points to 5.281%, while the 30-year yield declined about three basis points to 5.651%. The two-year yield fell three basis points to 4.802%.
The 10-year and 30-year yields had reached 24-year highs on Monday after data showed slower services growth, although the services PMI remained in expansion territory. Investors are now focused on Wednesday's release of the Federal Open Market Committee minutes from its September meeting for clues about future monetary policy.
