OpenAI brings Codex to ChatGPT mobile so developers can control agents on their laptops from their phones
OpenAI rolled out a preview of Codex in the ChatGPT mobile app for iOS and Android. Developers can start coding tasks, review outputs, steer execution, and approve steps from their phones while the agent runs on their own hardware — laptops, Mac minis, or devboxes.
Syncing happens in real time via a secure relay. No local files or credentials are exposed. The feature is live today in supported regions for all plans including the free tier, with Windows phone support coming soon.
Community response is mixed. Some developers are enthusiastic about mobile agent control; others are vocally frustrated and asking for GPT-4o back instead of new agent tooling.
TL;DR
Codex is now in your pocket — all plans, live today, runs agents on your own hardware via secure relay.

Dev Tools · xAI
xAI launches Grok Build, a coding agent CLI for professional engineers, at $300/month
xAI launched Grok Build, a coding agent and CLI targeting professional software engineers and complex coding tasks. The product is in early beta and available only to SuperGrok Heavy subscribers at $300 per month.
Grok Build is positioned as a direct competitor to Anthropic’s Claude Code. Elon Musk acknowledged xAI fell behind competitors in coding capabilities and said the company is rebuilding from the ground up — the product is being iterated on based on beta feedback.
TL;DR
xAI entered the coding agent market by Musk’s own admission from behind, at $300/month for early access.

Anthropic commits $200M to the Gates Foundation for AI in global health, education, and agriculture
Anthropic announced a four-year, $200 million partnership with the Gates Foundation. The commitment covers grants, Claude AI credits, and technical support for initiatives spanning global health, life sciences, education, agriculture, and economic mobility.
The collaboration targets public AI resources including health datasets, evaluation benchmarks, disease modeling tools, and tutoring applications. Primary beneficiaries include low- and middle-income countries as well as US programs.
Community reaction was predominantly negative. Replies drew widespread skepticism toward the Gates Foundation and frustration over simultaneous Claude model changes, including the Sonnet 4.5 deprecation.
TL;DR
Anthropic is putting $200M and Claude credits behind Gates Foundation work in health and education. The announcement thread was not well received.

A Georgia data center used 29 million gallons of water unmetered during a drought. It paid the bill. No fine.
Quality Technology Services ran two unmetered water connections at Project Excalibur, its data center campus in Fayette County, Georgia. Over 9 to 15 months, those connections drew approximately 29 million gallons — entirely unknown to county officials.
The period overlapped with moderate-to-severe drought conditions. County residents faced water restrictions and were told to stop watering their lawns due to low pressure. The county discovered the unauthorized usage only after complaints intensified and a public records request was filed.
QTS says the water was for construction activities — concrete work, dust control, and site preparation — not cooling. The company paid $147,474 in retroactive charges. No fine was issued; county officials cited QTS as their largest customer and preferred a “partnership approach” to enforcement.
TL;DR
29 million gallons, a drought, residents told to stop watering — and the bill came to $147,474 with zero penalty.
