Anthropic cuts Opus 5.5 prices, claims strongest model yet

Anthropic is in early-stage negotiations to lease up to 1 gigawatt of compute capacity from Stream Data Centers, which is majority-owned by Apollo Global Management. The facility would house tensor processing units designed by Broadcom and Google. The deal reflects ongoing competition among AI labs to secure dedicated infrastructure for large-scale model training and deployment.

China's internet regulator is investigating DeepSeek and Moonshot AI following allegations by Anthropic that both companies routed sensitive user data to Claude models without authorization. Anthropic published a 154-page report on September 10 detailing how seven Chinese companies were using Claude illicitly at scale, including an example where DeepSeek relayed requests from engineers building a police surveillance system to Claude. The investigation marks a significant escalation in scrutiny of data practices among Chinese AI firms and raises questions about the security of proprietary AI systems.

OpenAI and Anthropic were negotiating a legally binding agreement to stress-test each other's AI models, according to sources with direct knowledge of the discussions. The deal represents one potential safety strategy as OpenAI responds to employee concerns and external warnings about AI risks. The negotiations occurred before recent cybersecurity incidents involving OpenAI's technology intensified safety scrutiny.

Anthropic is operating a biology laboratory that conducts experiments. The move represents a tangible step toward the AI company's stated goal of using AI to advance disease research. This development comes as AI leaders have made broad promises about AI's potential to cure human disease, while some Anthropic researchers have simultaneously warned about AI safety risks.
