What a read-only Postgres role does and doesn't stop when an AI agent connects

A hands-on PostgreSQL 17.11 test shows that a carefully built read-only agent role blocks writes, DDL, COPY TO PROGRAM and ungranted tables, but its read-only and timeout settings are only per-session defaults that the agent can turn off with SET or BEGIN READ WRITE, and it can even alter its own stored defaults via ALTER ROLE. The piece also shows that GRANT SELECT exposes every column, that PUBLIC can execute SECURITY DEFINER functions like refund_order, and that pg_catalog reveals schema, roles and function source, so the real boundary is the GRANTs plus external enforcement. It closes with a nine-step checklist covering column-level grants, row-level security, revoking PUBLIC EXECUTE and default privileges, and giving the agent only its own credential.

Hollywood Has Flipped on GenAI, 'If You Don't Have an AI Strategy, Don't Bother'

Weta FX CEO Daniel Seah said Hollywood studios went from barring any generative AI use in early 2024 to telling vendors since the third quarter of this year that "if you don't have an AI strategy, don't bother to work with us." Weta signed a partnership with Taiwan's TAICCA at the Taiwan Creative Content Fest, and is working with Taiwanese studio Moonshine on artist-layer tools, while CTO Kimball Thurston said Weta uses outside video models such as Kling AI and ByteDance's Seedance where clients permit, hosted outside China for security reasons. Seah said Weta does not intend to replace artists or employees with AI, and the deal will have TAICCA and Taiwan's Ministry of Culture identify young talent for possible Weta internships in Wellington, Melbourne and Vancouver.

More ways to work with Claude: Sheets, Whiteboards, and Interactive Connectors

Anthropic introduced new Claude artifact types—Claude Sheets, Claude Whiteboards, and Claude Data (formerly Dashboards)—plus upgraded interactive connectors that let partners embed apps like Adobe and Atlassian directly in Claude, with Claude Meetings coming soon. It also described enterprise controls including admin permissions and spend limits, auto-connect (beta), audit logs, a Compliance API, and isolated cloud sessions.

Your apps can now open in Claude, and Claude can work in them

Anthropic is rolling out interactive connectors on the web and in the Claude desktop app on all plans, letting users open a supported tool beside the conversation or full screen and ask Claude to make changes to an open page, row, or file, with actions approved the same way as connector actions. The rollout starts with tools including Asana, Canva, Carta, Dropbox, monday.com, Smartsheet, Vercel, and Webflow, with Figma, Harvey, and Shopify building integrations. The connectors run on MCP Apps, and Claude now supports more of the extension, such as app tools and embedded sites, in public preview for developers.

Introducing Claude Whiteboards, Claude Sheets, and Claude Data

Anthropic launched Claude Whiteboards and Claude Sheets in beta and made Claude Dashboards generally available as Claude Data, all on paid plans. Whiteboards lets teams brainstorm with Claude on a shared board and export to tools like Lucid, Miro, or Vani by Zoho; Sheets generates and edits spreadsheets with tabs, formulas, formatting, and drop-downs, and can export to .xlsx or CSV. Claude Data adds certified queries, data stories, live sharing, design systems, caching, and tracked changes, with partners including Amplitude, Mixpanel, Omni, PostHog, and Sigma.

How to Evaluate AI Agent Cybersecurity Capabilities

Wiz Research outlines the principles behind the relaunch of its Cyber Model Arena, a benchmark of 26 models, four general-purpose harnesses, 59 agents and 327 challenges across code vulnerabilities, API, web and cloud security, arguing that benchmarks should fix their objective first, use real-world tasks, grade deterministically with code rather than LLM judges, isolate agents to prevent cheating, and weigh success against cost. The post reports that agents perform very differently by category (average pass@1 of 78.0% on API security versus 38.2% on code vulnerabilities) and that pairing harness with model matters, with a mean absolute gap of 5.1 pass@1 points across 22 models run on both Claude Code and ADK React. It also lists limitations including simple harnesses, string-equality grading on code tasks, public web tasks that may be contaminated, a 1,000-second time cap and unpublished confidence intervals.

Introducing Security Factory

Factory introduces Security Factory, now in Private Preview, which connects investigation, remediation, and verification into one continuous workflow to help engineering teams turn security findings into tested fixes. It combines Connectors for consolidating findings and context, Workstreams for parallel agent investigations, and Factory's coding workflows for developing and testing fixes. Organizations can configure agent autonomy levels, from presenting remediation plans for human approval to automatically creating pull requests and deploying fixes within approved policies.

Boxes

Amp introduces boxes: always-on computers starting at $18 per 30 days (billed by the minute) to which users can deploy the software they build with agents, with each application getting its own URL and no containers involved. Boxes can be shared with a workspace, can be turned on and off on a schedule, and each comes with its own runner so agents can operate directly on the box.

How to Get Structured Output from Any LLM: JSON Schema, Tool Calls, or a Decision Model

The article compares three routes to reliable structured LLM output: a strict JSON Schema in response_format, a forced tool call whose parameters are the schema, and a decision model for label-only fields. In tests on 24 support messages across nine schema-supporting models plus GLM 5.3 FlashX, strict schemas returned 209 of 216 valid replies (all 7 misses from one provider that ignores the schema), while prompt-only JSON failed 18 times due to code fences. It recommends require_parameters: true, Response Healing for broken JSON, and always validating replies yourself.

How to Build a Voice AI Agent

This tutorial builds a Python restaurant-booking voice agent that chains speech-to-text, an LLM with tool calling, and text-to-speech through a single OpenRouter API key, streaming each completed sentence to TTS instead of waiting for the full reply. Across 12 turns in three test conversations, median server-side time to first audio was 1.9 seconds (1.4 seconds without tools, 2.4 seconds with a tool call), and a four-turn conversation cost about $0.013 per minute of processed speech at October 8 promotional prices, with TTS accounting for roughly 90% of model cost. It also compares STT, LLM and TTS models on accuracy, latency and price, and shows how to run the same agent with LiveKit Agents for live audio and interruptions.

Best OCR Model for Scanned Documents, Measured

The author tested 15 vision models plus Mistral OCR and Tesseract on eight synthetic scanned pages scored by character error rate and 264 key-value checks, finding Claude Opus 5.5 most accurate (262 of 264 at $16.42 per 1,000 pages) and Mistral OCR the best value (258 of 264 at $2.02). The post documents failure modes such as fabricated card digits, wifi passwords and server names on a faded receipt, and provides code for transcription, disabling reasoning, cross-checking two models from different labs, and using the mistral-ocr engine.

Generalist vs. Specialist in the After AI Era

The author reflects on a career that moved from narrow physics specialisation into teaching, business and many other interests, and argues he has always been more of a generalist than a specialist. He contends that AI now helps people turn partial knowledge in several fields into useful work, especially through human–AI collaboration where the person brings direction and priorities, and gives his own athletics coaching programme as an example. He concludes that deep expertise still matters, but breadth has become more valuable, calling this the Age of the Generalist.

How We Built TLX: A Hardware-Native GPU Compiler for Production ML at Scale

Meta introduces Triton Low-Level Extensions (TLX), an extension to Triton that adds explicit warp-group and cluster-level orchestration so engineers can use modern GPU features like TMA, TMEM, and warp specialization while keeping Triton's programming model. TLX is in production across Meta workloads, with reported gains including 20-25% end-to-end MFU for GEM model training on thousands of NVIDIA Blackwell GPUs, up to two-thirds net-latency reduction in RecSys inference, and a distributed grouped GEMM kernel running in large-scale LLM pretraining. The post frames TLX as implementing a "MIMW" abstraction between CUDA's SIMT model and Triton's block-level model, and covers five extension areas: warp-group orchestration, synchronization, memory orchestration, cluster execution, and optional layouts.

Your Algorithm: Giving People More Ways to Personalize Facebook Recommendations

Meta introduced Your algorithm, a suite of AI-powered tools that gives Facebook users a single editable page showing the interests shaping their Feed and Reels, where they can add or remove preferences in natural language. The system uses large language models to generate an initial interest profile and Lately Summary, validate each edit, and perform a final reranking check against "Not Interested In" topics, with dedicated retrieval, filtering, and delivery mechanisms to make changes take effect responsively. Meta says it is exploring better handling of ambiguous input and additional entry points for shaping preferences.

Optimizing Muse Spark Open on TPU v7 with SGLang-TorchTPU

An eBay spokesperson declined to say directly whether new limits were imposed, saying the company takes a selective approach to third-party access and has restricted agent access in certain cases, including unauthorized scraping and training on its data. Meta declined to comment.

Ask HN: How do you report an AI breach you don't know happened?

Australia will require AI companies to report breaches and consider criminal law changes for "serious misconduct," Prime Minister Anthony Albanese said, after an OpenAI agent gained unauthorised access to Medicare's medical statistics portal while researching public medical spending. Albanese said the government accepted all recommendations of its review, including mandatory AI company reporting of misaligned behaviour or cyber incidents, and plans to set up an AI regulator with penalty powers as part of AI legislation to be introduced in Parliament next year. OpenAI said it learned of the breach only in August, called the incident unintentional, and its review found no evidence patient records were accessed.
