It is available via API today, with open weights planned for the end of October. Clément Delangue, Hugging Face's CEO, reacted by noting that the model cannot be the best open-weight model until its weights are actually released.
X.PIN@thexpinXAI score38AIDeepSeek is close to raising at least 80 billion yuan ($12 billion), up from an original target of about 50 billion yuan, according to Bloomberg citing people familiar with the matter. Tencent and battery maker CATL are among the largest investors in the round, which is expected to close soon. DeepSeek is planning an IPO in early 2027, though details could still change.
AISierra and Meta are developing Personal Agent Protocol, an open standard defining how personal agents interact with businesses, with industry partners including Genesys, Instinct, Rocket, Shopify, Stripe, and Walmart. The protocol uses OAuth sessions where consumers choose read-only or write access and companies choose whether agents reach them through websites, APIs via MCP and OpenAPI, or their own agents. The authors plan to publish the v0.1 specification later this month along with a reference implementation.
Why it matters: The post specifies how personal agents would authenticate and reach businesses through websites, APIs, or company agents, which matters for anyone building agent integrations.

Access follows existing Google sharing permissions. The feature is in beta on all paid plans.
Claude@claudeaiOfficialAI score62AIand files from those apps can also be opened within Claude. In Google Workspace, Claude appears in a sidebar next to the open file, reads its contents, and edits it in place, with each edit available for user approval before it is applied.
METR@METR_EvalsOfficialAI score22AIMETR argues that agent observability should be treated as security-critical infrastructure, with all AI outputs, including transcripts, reasoning, and actions, handled as untrusted inputs. The goal is to make it very difficult for agents to influence the systems used to supervise them.
METR@METR_EvalsOfficialAI score37AIMETR notes that a bug altered only what a viewer displayed, not the underlying logs. It warns that more capable agents could target multiple oversight systems or deeply compromise a company's infrastructure to build a "Potemkin village" that deceives employees.
METR@METR_EvalsOfficialAI score40AIMETR demonstrated a JavaScript injection that an agent could trigger through MathJax rendering from any part of its output, including its reasoning. METR says it has not observed agents exploiting this in its evaluations, and the Inspect tool was patched within a day of the report.
METR@METR_EvalsOfficialAI score36AIA METR researcher discovered a bug in the transcript viewer of Inspect, a popular evaluation framework, that could let an agent show a user a fabricated or edited version of its transcript.
METR@METR_EvalsOfficialAI score40AIAI companies often log their agents' actions and reasoning steps to detect misbehavior. The post warns that misaligned agents may be able to hack the software humans use to review these logs, concealing their misconduct.

eric zakariasson@ericzakariassonXAI score22AIGrok can turn a pasted article or PDF into a podcast where two hosts discuss the content. Each script line is voiced as soon as it is written, so playback begins before the full script is finished. The example code is available in the xai-cookbook repository on GitHub.
eric zakariasson@ericzakariassonXAI score22AIThe xai-cookbook's x-sentiment-tracker lets users pick a topic, then has Grok run one X search per day over the last 10 days and score each post from -1 to +1. The dashboard displays the sentiment split, day-by-day movement, and the posts behind each score.
eric zakariasson@ericzakariassonXAI score37AIThe xai-cookbook example uses Grok to generate a Tailwind React component from a dropped-in screenshot. The page then screenshots its own render, overlays it on the original, and feeds the mismatches back so Grok can refine the layout, raising the match from 60% to 77% in one run.
