Anthropic is expanding access to its most advanced AI models to selected organisations for high-risk cybersecurity testing in collaboration with the US government.
Oil prices were little changed as rising Middle Eastern exports and planned emergency stockpile releases eased supply concerns.
Gold prices rose as Treasury yields and the US dollar moved lower ahead of the Federal Reserve’s September meeting minutes.
US Treasury yields also declined after reaching multi-decade highs in the previous session.
Anthropic expands AI model access to cyber firms
Anthropic said Tuesday that verified organisations will be able to access its most capable AI models, including Claude Opus 5.5, Claude Sonnet 5.5 and Claude Mythos 5.1, as well as new models released in the future.
The selected organisations will be able to conduct high-risk offensive testing of safety systems protecting critical infrastructure, including power grids, banks and flight operating systems.
The latest programme expands Project Glasswing, under which Anthropic previously gave limited access to its Mythos model to US government agencies, financial institutions and major software providers.
Anthropic said every member of Project Glasswing would receive access under the latest programme, while new organisations will require review in partnership with the US government.
Different cybersecurity teams will receive different levels of access.
Red teams conducting authorised hacking tests will receive broader permissions, including for offensive testing, although Anthropic said it would continue blocking behaviour that could cause physical harm or mass disruption.
Verified defence cybersecurity teams will receive a lower level of access but will be able to perform tasks such as malware reverse engineering and incident response.
The expansion comes after concerns about the cybersecurity risks posed by increasingly capable AI models.
JPMorgan Chase CEO Jamie Dimon said Tuesday that Anthropic’s Mythos model had increased global cybersecurity risks tenfold.
Oil prices remain 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%, at $100.98 a barrel, while US West Texas Intermediate futures rose 16 cents, or 0.36%, to $89.75.
The higher flow of crude from the Middle East has eased some concerns about supply shortages.
Vitol’s CEO said 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 previous seven to 10 days.
Saudi Arabia’s East-West Pipeline had also transported 5.8 million barrels to the kingdom’s Red Sea export hub of Yanbu as of Tuesday morning, 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 oil from emergency reserves, although details on the breakdown and participating countries have not yet been provided.
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 weaker dollar provided support for the precious metal.
Gold can face pressure from higher interest rates because investors may favour 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.
