CI IS DEAD. LONG LIVE CI.

Everyone's talking about the bottleneck shifting... our customers just want something stable as they scale, with actually good DX, that gets out of the way. Buildkite is the pro-tool for CI orchestration, and when you're setup, you can forget we exist. Programmable primitives you control. No compromises. Good enough for Cursor, OpenAI, Anthropic, Perplexity, Nvidia, Uber, Airbnb and more. Build and test faster, more securely, more reliably, with the CI engineered for frontier scale, used by the teams setting the pace.

OPENAI NEARS UP TO $30 BILLION FUNDING ROUND AT $1.25 TRILLION VALUATION LED BY UAE INVESTORS

OpenAI is closing in on a funding round that could value it at more than $1 trillion. Investors from the United Arab Emirates are leading the round. The round is being positioned as an opportunistic bridge ahead of a potential IPO. OpenAI is aiming to secure signatures by the end of next week, but the final size of the round is still being determined.

INTRODUCING 1PASSWORD FOR AGENTS

1Password introduced a platform that lets AI agents authenticate to websites without accessing users' passwords directly. Agents can request credentials from a user's vault, and once approved, 1Password autofills them into the destination site while keeping the credentials hidden from the agent.

WORLDTUI: I TRAINED A 360M MODEL TO PRETEND TO BE A TERMINAL

WorldTUI is a 360-million-parameter model fine-tuned to act as a terminal. The model predicts how the screen will change for every key press, and there is no shell or file system behind it. WorldTUI can create files, run vim and tmux, play snake, and usually remember commands. It can repair mistakes and decode screen rows in parallel. A browser demo is available.

HOW RESEARCHERS TESTED OPENAI'S INTERNAL AGENT MONITORING

METR and Redwood Research conducted a three-week security assessment with access to OpenAI's internal infrastructure, identifying vulnerabilities that could allow AI agents to evade monitoring, bypass sandbox restrictions, or conceal actions.

DOES FLAPPING AIRPLANES MEAN SHORT TIMELINES AND HARD TREATY ENFORCEMENT?

Flapping Airplanes' potential valuation jump from $1.5B to $5B may reflect investor hype rather than verified technical progress. Breakthroughs in sample-efficient AI could accelerate superintelligence timelines and make compute-based treaty enforcement harder.

CLAUDE'S TEXT OUTPUT NOW CARRIES AN INVISIBLE WATERMARK

Anthropic's latest Claude models embed a SynthID-Text-based watermark in all text output to comply with the EU AI Act. It works by nudging choices among near-equivalent words, adds no hidden characters or tokens, and carries no information about the user.

HOW THE US AND CHINA COULD VERIFIABLY SLOW AI

A unilateral US pause will fail because rivals would catch up within about a year, so any slowdown needs a treaty that catches defection early. This post surveys how one could govern compute through remote sensing, on-site inspections, and hardware mechanisms like chip licensing and location verification.

HOW WE DEPLOY TRILLION-PARAMETER FRONTIER MODELS ON CEREBRAS

A single Cerebras WSE-3T wafer has 44 GB of on-chip memory. Trillion-parameter frontier models need terabytes of memory for their weights alone. This post explains how the company splits a large frontier model across multiple WSE-3T wafers. It covers how models are filled into on-chip memory, how models are mapped across multiple chips, and how Cerebras handles a high number of concurrent requests.

A NOVEL SELF-DISTILLATION METHOD

Perplexity's JOLT is a self-distillation method that jointly trains a model as both teacher and student, adapting feedback to the student's capabilities. It improved performance and training efficiency across mathematical reasoning, coding, and agentic tasks.

WHAT HAPPENED TO THE MISSING GEMINI 3.5 PRO MODEL THAT NEVER SHIPPED?

Google had both Flash and Pro versions of the 3.5 series. However, there were gaps in the model's agentic capabilities, particularly around coding. The team felt the fastest way to climb that hill was to use Flash, as the smaller model allowed for more iterative loops. By the time the team had improved Flash's abilities, Argon pre-training was done.
