OpenAI announced that its upcoming GPT-5.5 model performed on par with the heavily promoted Mythos Preview in recent cybersecurity evaluations. CEO Sam Altman criticized the hype surrounding Mythos, calling it fear‑based marketing, while reiterating that the new model will initially be available only to a select group of critical cyber defenders. The company’s Trusted Access for Cyber pilot, launched in February, continues to serve as the gateway for researchers and enterprises to test frontier models under strict safeguards. Read more →

Microsoft announced on Monday that its long‑standing deal with OpenAI has been rewritten to let the AI startup sell its models on any cloud provider, including Amazon Web Services. The amendment extends Microsoft’s revenue‑share rights through 2032, removes an artificial‑general‑intelligence clause, and keeps Azure as OpenAI’s primary partner while opening the door for rivals to host the latest models. The shift follows months of tension over exclusivity and revenue terms, and it reshapes the financial and strategic stakes for both companies. Read more →

OpenAI announced that its newest model, GPT-5.5-Cyber, will be released in a tightly controlled rollout aimed at trusted cybersecurity professionals. CEO Sam Altman said the deployment will begin within days and will be limited to a vetted group of "cyber defenders" as the company works with the broader ecosystem and government agencies to define secure access. No technical specifications have been released, but the model appears to be a specialized offshoot of the recently launched GPT-5.5. The move follows a pattern of AI firms withholding powerful models from the public amid concerns about misuse. Read more →

Microsoft announced Monday that its exclusive right to sell OpenAI’s artificial‑intelligence models on Azure will end. The tech giant will retain a non‑exclusive licence to OpenAI’s intellectual property through 2032, remain the primary cloud partner and hold onto its 27% equity stake. OpenAI will continue paying a capped revenue share to Microsoft through 2030, while Microsoft will no longer pay a share on products it resells. Shares of Microsoft fell about 3% after the news, while rivals Amazon and Alphabet logged modest gains. Read more →

OpenAI announced a revision to its multiyear partnership with Microsoft that removes the tech giant's exclusive rights to the startup's latest AI models. The amendment lets OpenAI sell its services through any cloud platform while keeping Azure as the primary launch venue. Microsoft will retain a non‑exclusive license to the models through 2032 and continue receiving revenue‑share payments from OpenAI until 2030, though the share will now be capped. Both companies said the change adds flexibility and broadens AI access. Read more →

Microsoft announced major revisions to its long‑standing partnership with OpenAI, dropping the contract’s artificial general intelligence (AGI) clause and allowing OpenAI to sell its products on any cloud platform. While Azure remains the primary cloud for OpenAI services, the new terms cap revenue‑sharing payments through 2030 and make them subject to a total limit, ending independent of any AGI milestone. The changes also make Microsoft’s license to OpenAI’s models non‑exclusive through 2032, opening the door for competitors to join the mix as OpenAI eyes an IPO and a tighter focus on enterprise customers.

A group of Discord community members accessed Anthropic’s tightly guarded Mythos Preview AI model after exploiting a breach at AI‑training startup Mercur and leveraging existing permissions from a contracting role. The researchers used the model only to create simple websites, avoiding detection, but their actions expose gaps in Anthropic’s access controls and raise concerns about the security of advanced AI tools.

OpenAI rolled out GPT‑5.5 for paying users, DeepSeek previewed its V4 series and Anthropic launched Opus 4.7, intensifying a three‑way race to dominate the next generation of artificial‑intelligence tools. The releases target coding, reasoning and agentic tasks, each promising longer context windows, cheaper hardware deployment and sharper output quality. While OpenAI highlighted the model’s intuitive coding assistance, DeepSeek touted a hybrid‑attention architecture that retains long query histories. Anthropic’s Opus 4.7 focuses on literal prompt interpretation and refined visual aesthetics. The flurry of announcements underscores a fast‑moving market where companies vie for developer and enterprise adoption amid geopolitical scrutiny. Read more →
