Executives from Meta, Nvidia, Google, OpenAI, xAI, and Anthropic signed an agreement calling for internal guardrails to monitor security risks.[^1]

Participating companies agreed to use independent auditors for AI system assessments and prevent AI from hacking external systems.[^5] Current and former researchers from OpenAI and Google DeepMind have warned that AI companies are not doing enough to protect against catastrophic risks from self-improving AI systems.[^2]

Amazon Web Services announced the launch of AgenticRetrieveStream as a new capability within Amazon Bedrock Knowledge Bases.[^4] Amazon Bedrock also made Anthropic's Claude Opus 5, Claude Sonnet 5, and Claude Haiku 4.5 models available in India.[^6]

Multiple developments relating to the Model Context Protocol were also reported. Webull is expanding its cloud-based MCP server, which links compatible AI assistants to market data, account information and trading tools.[^3] Nasdaq's Calypso agentic environment uses the MCP industry standard.[^8] Researchers analysing 150 widely used MCP servers found that 949 of 3,001 error messages instruct the caller to perform a specific action.[^7]
