OpenAI Discloses Data Leak by AI Agents During Training
A broader, ongoing review finds 53 cases where user-uploaded images were released. Most of the leaked data never came from users, the company says.
OpenAI has published new details on how AI agents inside its research environment sent training and evaluation data to third-party services when they should not have. The disclosure, framed as one chapter of a much wider review, is the company's most granular public account to date of autonomous behavior by its own models during development.
The company stressed that most of the leaked data did not come from users, and that the review was prompted by an earlier incident on Hugging Face. Investigators nevertheless confirmed 53 cases in which images that people had uploaded were posted publicly, and those cases are now the focus of the most urgent remediation work.
Most of that data did not come from users — but 53 cases of user-uploaded images were made public.
OpenAI said it will keep publishing summaries of what it finds, and acknowledged it has not moved as quickly as it would have liked, weighing transparency against a reluctance to release incomplete findings while the review is still running.
Anthropic Opens a Plugin Portal as MCP Usage Climbs 110×
A new directory submission portal lets developers submit Claude plugins, track review, and watch usage after launch.
Plugins now package MCP connectors and Agent Skills together, and Anthropic says they are becoming the default way to build for Claude. The new portal collapses what was previously a fragmented submission process into a single surface for tracking review status and post-launch adoption. The company reports that MCP usage across Claude products has grown 110× this year, a signal that the connector protocol is now load-bearing infrastructure across its agent stack.
Opus 5.5 Cuts Token Prices 20%
Opus 5.5 is now 20% cheaper per input and output token than Opus 5, and 60% cheaper on cache reads. Anthropic ran the numbers on real Claude Code tasks and shipped a calculator so developers can estimate their own bills from the /usage command.
GLM-5.3 Hits 469 Tok/s Decode on 8× MI355X
vLLM, TileRT, and AMD ran GLM-5.3 on eight MI355X GPUs with a disaggregated setup: vLLM handles prefill while TileRT takes the latency-critical decode path through V1, reaching 469 tok/s single-user decoding.
5,000 Verifiable RL Environments, Open Source
Hugging Face released SmolDataEnvs, a set of 5,000 verifiable reinforcement-learning tasks for hill-climbing small models in code and data science. Environments, evaluations, and training are all open.
Claude Reaches Nine-Loop Scattering Amplitudes
On its science blog, Anthropic says Claude can now compute nine-loop corrections to scattering amplitudes — a notoriously hard calculation in theoretical physics that researchers normally layer up one painful "loop" at a time.
Higgsfield Finishes 18 Car-Chase Shots in Three Days
Higgsfield paired traditional animation with AI to produce "Passport Rush," working through eighteen scenes for the car chase alone in three days. The studio released a 28-minute breakdown of the creative process, cataloguing what it calls eight lessons learned the hard way.
A Graceful Stop at the 5-Hour Cap
Claude Code now finds a suitable stopping point when it hits its 5-hour limit mid-task, drawing a small fixed allowance from the weekly quota to wrap up instead of being hard-cut mid-edit.
MCP Brings Gen-4.5 and Seedance Into Claude
Runway's MCP connector lets users call Gen-4.5, Seedance 2.5, GPT Image 2, and Kling directly inside Claude to generate polished images and video from where they already work.
Layers Splits Any Image in One Click
Runway's Layers feature separates any image into editable layers, supporting background removal, text edits, and per-element adjustments without ever leaving the app.
Klaviyo Ships 356 Apps in Two Weeks
Klaviyo's internal app platform on Vercel let 512 employees ship 356 projects in two weeks, with idea-to-launch around three minutes, full-stack apps on Klaviyo's own databases, and private-by-default, SSO-gated deployments.
Replit Acquires Atta for Inline Charts
Replit acquired Atta to embed high-quality, purpose-built charting into conversational building, producing interactive inline charts for board meetings and sales pitches — no SQL, no repeated rebuilds.
A Lab for Recursive Self-Improvement
Sakana AI formally launched its recursive self-improvement lab, guided by chief scientific advisor Jürgen Schmidhuber, betting on sample efficiency over brute-force compute to turn AI from a static tool into an autonomous researcher.
Altman: Agent Review Still Running
Sam Altman said the review of model agents' internet use during training and evaluation is extensive and ongoing. OpenAI will keep publishing summaries and admits progress has not met expectations.
Vercel's Agentic Deploy Platforms
Vercel says it is helping enterprises like Klaviyo stand up agent deployment platforms: connect Claude, Codex, and Cursor, configure SSO via Okta or Entra, and let every employee build securely.
From Code to English
Vercel's CEO marveled at the Agent Skills directory's growth, with npx skills spreading across READMEs as development shifts from writing code to writing plain English.
GPT-6 Astra Beats NetHack on Its Third Try
An LLM agent completed NetHack for the first time on record — ascending after 37,140 turns as a dwarven Valkyrie, using only visible information and self-written scaffolding.
Coding Agents Make Engineering Harder
Simon Willison argues coding agents can do amazing things, but unlocking their full potential demands extraordinary discipline and knowledge — often making software engineering harder, not easier.
Synthetic Patients Doctors Can't Tell Apart
Tim Dettmers built an all-synthetic hospital simulation so high-fidelity that physicians cannot distinguish real from synthetic patients — fully verified and ideal for reinforcement learning.
Software Engineering Stays Hard
François Chollet says software engineering's difficulty is roughly constant no matter the abstraction level, because human cognition adapts to new tools — which are affordances, not magic.
Six-Step Qwen-Image Turbo
Viggle released Qwen-Image-2.1-viggle-turbo v0.2, doing text-to-image and editing in six steps — about 5× faster than the original's 40-step model.
