OpenAI launches reusable Codex cloud environments
At its Dev Day, OpenAI announced new capabilities for its software engineering agent Codex, including reusable cloud development environments accessible from any device. These environments are more persistent and configurable, allowing faster task startup and shared team workspaces. The updated Codex CLI supports voice commands, and a new /agents view helps delegate and track tasks. Codex can now be integrated into code review within the ChatGPT desktop app, enabling summaries and feedback on GitHub and GitLab. Additionally, OpenAI introduced Codex Security Cloud for repository scanning and fix preparation, leveraging models from its Daybreak Blue initiative. API updates include a Decisions API using Luna and an updated Agents API with computer use and AWS Bedrock integration.

Anthropic launches cheaper AI model Sonnet 5.5
Anthropic has released Claude Sonnet 5.5, an upgraded mid-tier AI model designed for everyday tasks such as coding, bug fixing, and document creation. Priced at $2 per million input tokens and $10 per million output tokens, it is over 30% faster than Sonnet 5, and due to reduced token usage, costs per task can drop by up to 30%, making it more cost-effective. While not advancing frontier capabilities, it outperforms Opus 5.5 on agentic coding benchmarks and significantly improves on Terminal-Bench 4.0 (70.6% vs. 10.3%). It also includes enhanced cyber safety mechanisms, making it the first Sonnet model with safeguards comparable to Opus 5. Available on AWS, Google Cloud, and Microsoft Azure, it targets cost-conscious customers. The launch follows Opus 5.5 and a call for a slowdown in AI development. A new Haiku model is expected soon.
Oracle Invokes Force Majeure on $18B AI Data Center
Oracle has invoked a force majeure clause to shield itself from financial obligations on Project Jupiter, an $18 billion AI data center in New Mexico slated to serve OpenAI under the Stargate initiative. The construction is halted by environmental lawsuits, energy supply issues, and local protests. Oracle and developer Blue Owl reassure that commitments remain, but banks like Santander, Jefferies, and BNP Paribas are seeking to offload the loans at a discount on secondary markets. Analysts warn that only 35% of planned AI infrastructure projects will materialize due to energy and funding gaps. Morgan Stanley estimates $2.9 trillion in global data center investment needed by 2028, with hidden debts among big tech reaching $1.65 trillion, Oracle owing over $270 billion.
Publishers Face New Jersey Data Broker Law Surprise
New Jersey's data broker law, unique in the U.S., targets 'data collectors'—companies that collect data directly from consumers and sell or license it, even to a single broker. Publishers, who typically have direct audience relationships, may inadvertently qualify. The law, effective immediately upon signing June 30, has no minimum thresholds, and 'sale' is broadly defined to include routine ad tech arrangements. Qualifying companies must register by April 2027, with annual fees ranging from $5,000 to $1.5 million based on the number of New Jersey consumers' data sold. The state plans to suspend enforcement pending legislative fixes, but the sensitive data ban remains in effect. Experts advise publishers to conduct thorough data inventories and reassess downstream data-sharing relationships to mitigate financial and reputational risks.
