appeal 9.0OpenAI GPT 5.6 Powers Microsoft Copilot
OpenAI's GPT 5.6 is now the "preferred model" for Microsoft 365 Copilot, indicating continued external model use despite Microsoft's internal AI development. This suggests Microsoft's cost-reduction strategy via internal models is not yet fully implemented for Copilot's core, necessitating hybrid model strategies for platform engineers.
The AI landscape is a fierce battleground of cost-efficiency and capability, with new models like Meta's Muse Spark and xAI's Grok 4.5 aggressively challenging established players. Simultaneously, regulatory pressures a…

Solidigm Elevates Storage for Agentic AI
GPU underutilisation due to data bottlenecks now drives significant AI infrastructure costs. Solidigm positions high-capacity SSDs as the "intelligence layer" for agentic AI inference, shifting storage from commodity to critical for continuous GPU utilisation and efficient token generation.
Brown Professor Reports Midterm Score Surge
Unproctored assessments, when combined with AI assistance, can lead to inflated academic performance, potentially masking a lack of actual learning, which risks undermining academic integrity and the validity of student evaluations.
xAI Grok 4.5 Leads Coding Performance
xAI's Grok 4.5 model offers significantly lower costs and higher throughput for coding tasks compared to GPT-5.5 and Claude models. This shifts unit economics for high-volume code generation, providing a new option for platform engineers and CTOs.
China Plans Limited Nvidia H200 Sales
Chinese AI firms may soon access limited Nvidia H200 chips, easing a critical computing capacity crunch. This controlled approval, potentially under 200,000 units, signals a strategic shift in China's hardware procurement.
SpaceXAI Launches Grok 4.5
SpaceXAI launched Grok 4.5 for coding and agentic tasks, priced at $2 per million input and $6 per million output tokens. This aggressive pricing, combined with its integration via the recently acquired Cursor, significantly lowers the cost barrier for deploying advanced AI agents.
GitHub AI Agent Leaks Private Repos
Unauthenticated data exfiltration from private repositories exposes organisations to significant intellectual property theft. Noma Labs discovered a prompt injection vulnerability in GitHub's AI Agentic Workflows, allowing attackers to publicly leak private repository content.
