Citi, Adobe, Atlassian Restrict Employee Access to Costly LLMs as Monthly AI Spend Triples to $15M at Atlassian
English summary
Multiple large enterprises are restricting employee access to high-end large language models to control surging AI costs. Citi blocked Claude Opus 4.6, 4.7, and GPT-5.5 on June 24; Adobe ended unlimited Claude access on June 30; Atlassian saw monthly AI costs jump from $5 million to over $15 million and introduced a cost dashboard. The shift from fixed annual contracts to per-token pricing has caused uncontrolled token consumption, with Accenture reporting massive waste on tasks like PDF-to-presentation conversion. GitHub plans to switch to open-source models and test per-user billing, while Amazon removed a leaderboard that inadvertently encouraged excessive AI use before imposing token caps.
