OPENAI'S CHATGPT UPDATED TO MAKE IMAGES BETTER AND FASTER

The new version of ChatGPT Image is designed to make and edit images more precisely. It can generate pictures up to four times faster than the previous image-generation model. OpenAI is creating a new section within ChatGPT specifically for making images. The company is aiming to cater to a mix of personal and professional uses.

GPT-IMAGE-1.5

OpenAI has launched GPT-Image-1.5, a faster and more accurate image generation model with improved instruction-following and editing. The rollout follows competitive pressure from Google's Gemini 3 and Nano Banana Pro models, which recently led key benchmarks.

HOW TO PROMPT V0

When prompting v0 to build web apps or components, it's important to know three core methods: specify the product service (components, data, and actions), define the context of use (who, when, and for what outcome), and outline constraints and taste (style, platform, and layout). By providing these specific details, v0 can generate faster, make smarter UX decisions, and create cleaner, more maintainable code.

PROMPT INJECTION INSIDE GITHUB ACTIONS: THE NEW FRONTIER OF SUPPLY CHAIN ATTACKS

PromptPwnd is a new vulnerability class that affects GitHub Actions and GitLab CI/CD pipelines that use AI agents like Gemini CLI, Claude Code, and OpenAI Codex. In this vulnerability, untrusted user input from issues, pull requests, or commit messages is injected into prompts, leading to the execution of privileged tools. The attack allows secret exfiltration by tricking AI agents into leaking GITHUB_TOKEN or cloud credentials through shell commands such as gh issue edit. Google's Gemini CLI repository was confirmed vulnerable before the patch. To mitigate this, organizations should restrict AI toolsets, avoid injecting untrusted input into prompts, treat AI output as untrusted code, and limit GitHub token permissions by IP.

AAVE DAO VS. AAVE LABS - TOKEN HOLDERS LOOK TO RECLAIM CONTROL

An AAVE token holder has proposed a radical escalation in Aave governance, using a “poison pill” lawsuit to transfer Aave Labs' IP, trademarks, and even equity to the DAO, effectively turning the for-profit developer into a DAO subsidiary. The move follows backlash over a CoW Swap integration that redirected frontend swap fees from the DAO to a private address, reigniting long-standing tensions over who controls Aave's brand, revenue, and protocol direction.

WARNER BROS. PLANS TO REJECT PARAMOUNT BID ON FUNDING, TERMS

Warner Bros. plans to reject Paramount's hostile takeover bid due to concerns about financing and other terms. The board will urge shareholders to reject the tender offer. It views the company's existing agreement with Netflix as offering greater value, certainty, and terms than what Paramount has proposed. While Warner Bros.' agreement with Netflix bars it from soliciting proposals from other bidders, it is allowed to entertain incoming proposals.

IF AI COULD INTERACT AND LEARN FROM THE PHYSICAL WORLD, COULD IT MAKE MORE SCIENTIFIC ADVANCES?

OpenAI partnered with Red Queen Bio to introduce a new evolutionary framework that uses GPT-5 to optimize cloning protocols. The project involved the pilot of an autonomous robot to carry out the protocols. GPT-achieved a 79x cloning efficiency gain and introduced a new enzyme-based approach. While this is not a bio breakthrough, the novel optimization shows that GPT-5 is at the level of a competent PhD student at this task.

SAWING A DAM IN HALF (ON PURPOSE)

Fontana Dam started showing cracks in 1972, caused by concrete expansion. Engineers decided to give the concrete more room to grow rather than patching cracks as they appeared. They cut a relief slot all through the dam without draining the reservoir or causing any disruptions to the hydropower plant. This post explains how this was achieved. A video showing footage of the procedure is available.

ON THE SUCCESS OF ‘NATURAL LANGUAGE PROGRAMMING'

Machines can now be programmed in our native tongues. This year, the industry has made significant progress on how to use AI agents and is seeing significant returns from that effort. There's still more work to learn how to use them efficiently, but there's no doubt that the technology is the future of programming. This will bring the power of computing to more places, more people, and more problems.
