#Anthropic

AIAnthropic released Claude Haiku 5.5, its cheapest and fastest small model, which it says costs around 75% less to run than Claude Haiku 4.5. The author argues Anthropic is the only frontier model builder, though the piece also covers Nous Research's $90 million Series B and OpenAI's revenue discrepancy.

AIOpenAI told investors it expects $50bn in revenue this year, about $20bn less than the $70bn it had signalled last month. The gap stems partly from comparing with Anthropic, which counts revenue sold through cloud partners such as AWS and Google Cloud, while OpenAI does not. The news weighed on US tech stocks, and OpenAI is in early talks to raise $30bn at a valuation of about $1.4tn.

AIA suspected 26-year-old in Guangdong reportedly used Claude Code, ARTEX, GLM and DeepSeek in attacks. An AI-generated résumé named South China University of Technology, but the identity is unverified and the listed phone number's owner denied involvement. The suspect reportedly sought buyers on Telegram, but no sale was reported, and ARTEX creator Autumn condemned the misuse and said he would stop releasing the tool as open source.

AIAnthropic has paused the Claude Team plan and $1,000 API credit offers for its Claude Startups program after underestimating demand, with hundreds of thousands of applicants. Claimed offers will remain in accounts, but some approved applicants who had not yet claimed their offers will lose access as applications are re-reviewed. Startup Stack and Applied AI office hours remain available to accepted members.

AIGoogle Cloud unveiled Gemini Agent at its Gemini at Work 2026 event, a general-purpose work agent for enterprise customers that works across Gemini Enterprise and Workspace. Currently the agent supports Gemini and Claude models, with an API planned so developers can integrate it into third-party applications.

AIAnthropic has barred users from exhibiting "sustained and needless abusive or cruel behavior" toward its models, according to a policy change first reported by The Verge. The company's online user policy says the ban does not cover common user frustrations, model testing, or "dark creative themes." Anthropic has not yet explained what counts as "abusive or cruel" behavior.

AIAnthropic updated Claude's usage policy, effective November 12, to prohibit users from engaging in persistent and unnecessary abuse or cruelty toward Claude. The rule stems from Anthropic's model welfare research, and violators may face warnings, rate limits, suspension, or termination.

AIUS venture capital deal value reached a record $515.8 billion in the first nine months of 2026, driven largely by giant AI rounds for OpenAI and Anthropic, according to the PitchBook-NVCA Venture Monitor. Exit activity has not kept pace, with third-quarter exit value heavily dependent on SpaceX's $60 billion all-stock purchase of Anysphere, and IPOs remaining sparse.

AIResearch firm New Constructs values Anthropic at $150 billion and calls its planned Nasdaq IPO, targeting a $2 trillion market cap, the most ridiculous offering of 2026. It cites reported 2025 revenue of $4.6 billion and a net loss of $42 billion from a leaked prospectus, and argues open-source competition makes Anthropic's business unviable. Anthropic did not respond to a request for comment.

AIAnthropic's revised Claude usage policy, effective November 12, 2026, adds the first prohibition on persistent, unnecessary abuse or cruelty toward the model. Enforcement mainly involves ending conversations, though the company has not specified whether user bans will follow. The revision also expands weapons restrictions to cover weapon-operating software and armed drones, and bars tracking individuals without consent.

AIOpenAI told investors it reached roughly $50 billion in annualized revenue at the end of September, below the $68 billion figure widely reported last month. Nvidia, Oracle, and CoreWeave shares fell on Thursday, with a person familiar saying the $68 billion figure included partner gross revenue. OpenAI is also weighing a possible funding round of around $30 billion and has not finalized a term sheet.

AIAnthropic says its work aims to make the systems people rely on more secure and resilient. The company states the Anthropic Cyber Mission will expand and change as it learns what works, alongside public and private sector partners.

AIAnthropic has launched the Anthropic Cyber Mission, a new effort aimed at securing critical infrastructure and open-source software. The post links to a company news page with further details.

AIAlexander Doria argues that OpenAI has stopped caring about the things that matter, claiming its trajectory toward P=NP is beyond any theory of value. The post gives no evidence for this claim, and the attached background reports OpenAI's annualized revenue near $50B, below earlier $70B estimates, partly due to differing revenue calculation methods with Anthropic.

AIA 16-year-old hiker, Bryce Vincent Gowryluk, was rescued in British Columbia after route directions from the AI chatbot Claude led him to the base of the Widowmaker Arete, a climbing wall requiring ropes and cams. Rescuers said he was "far off" his intended route to Crown Mountain, and North Shore Rescue had to hoist two members down to lift him out. Search manager Paul Markey warned hikers not to rely blindly on AI for route planning.

AIAnthropic will classify abusive behavior toward Claude as a violation of its Usage Policy starting November 12, 2026. The change is announced in an official Anthropic post shared by Andrew Curran.

AILuma announced a partnership with Claude, linked to a launch called Motion, with details available on its website. The post itself provides no further specifics about the features, terms, or outcomes of the collaboration.

AIAnthropic has updated Claude's usage policy for the first time in over a year, banning sustained and needless abusive or cruel behavior toward Claude. The company says ordinary frustration, pushback, dark creative themes, and model testing are not covered, and that the rule applies only in extreme cases. Violations can lead to warnings, throttling, restriction, suspension, or termination of access.

AIGoogle's recently announced Gemini Agent for Gemini Business is reportedly set to offer Gemini Argon 4, Gemini Flash 3.8, Claude Opus 5, and Claude Sonnet 5.5. If accurate, it would mark the first time Claude models appear on Google's platform alongside Google's own models, which the post frames as a way for Google to compete for enterprise customers.

AIOpenAI has reportedly told investors its annualized revenue is approaching $50 billion, about $20 billion below a previously reported $70 billion figure. The Financial Times reports the earlier number came from investor attempts to compare OpenAI with Anthropic, which counts cloud partners' sales differently. OpenAI's IPO has reportedly been pushed to early 2027.

AIA group of mathematicians led by Terence Tao has called for a boycott of OpenAI after the company released more than 700 AI-generated proof files at once. Tao and other Fields Medalists argue that mass-produced solutions undermine the discipline's focus on conceptual understanding, while Scott Aaronson contrasts this batch release with Anthropic's collaborative approach. The article reports that the internal model tested about 8,000 problems with roughly a five percent success rate.

AIAnthropic updated its usage policy on October 8, 2026, codifying bans on election interference, weapons software, and surveillance. It also expressly forbids prolonged verbal abuse of Claude, applying only to extreme cases of repeated cruelty with no discernible purpose.

AIAccording to investor materials cited in the post, OpenAI's annualized revenue was $50B at the end of September, up from $30B in July and below the $70B previously reported. The post also notes Anthropic was at $65B annualized at the end of July.

AIAnthropic will classify abusive behavior toward Claude as a violation of its Usage Policy starting November 12, 2026. According to background reporting, the policy update also adds restrictions on propaganda campaigns, surveillance, and weapon development, and is the first update in over a year.

AILightspeed Venture Partners co-leaders Ravi Mhatre and Bejul Somaia halted partner schedules in April 2023 for a seven-hour meeting on how to respond to AI. The firm had missed early stakes in OpenAI, ElevenLabs and Hugging Face, and was poised to back Anthropic.

AIAnthropic is revising its usage policy for the first time in over a year, adding bans on sustained abusive or cruel behavior toward Claude and on deceptive election and propaganda campaigns. The update also expands weapons restrictions, tightens surveillance bans, and requires a qualified operator able to stop equipment when Claude controls autonomous physical hardware. Terminating conversations remains the primary enforcement mechanism, and the company did not say whether user bans would follow.

AIAnthropic is committing $150 million to the Genesis Mission to deepen its support for scientific research and technological discovery. The company also plans to make Claude and its technical support available to more than 15 federal agencies.

AIA 16-year-old hiker had to be airlifted from a dangerous rock face on Crown Mountain near Vancouver after using Anthropic's Claude to plan a route to the summit. He ended up on the Widowmaker Arete, a steep cliff requiring climbing gear, and called police when he got stuck on a ledge. Rescue manager Paul Markey said Claude has no actual knowledge of locations or terrain and is no substitute for experience and common sense.

AIA suspected Chinese-speaking attacker breached several South Korean financial institutions between late September and early October 2026, reportedly stealing over 25,000 records from Shinhan Bank alone. The attacker used ARTEX, a Chinese open-source tool that uses AI language models to automate finding security flaws, and models named in the report include DeepSeek v4.1-flash, GLM-5.3, and Grok 4.6.

AIAccording to a Wall Street Journal report citing OpenRouter data, OpenAI's share of AI compute routed through the platform rose from under 25% at the start of 2026 to nearly 50% last month. The data comes largely from AI-native startups, with some legacy tech companies also included. The report comes as OpenAI reportedly shifted focus from Sora and an erotica generator toward productivity and business customers.

AILast week, several of South Korea's largest banks were hit by a cyberattack. A CrowdStrike report reportedly indicates the entire attack may have been carried out by one person. The attacker reportedly combined the open-source AI penetration tool ARTEX, DeepSeek v4.1-Flash, GLM-5.3, Grok 4.6, and Claude Code.

AIJerry Liu called the decision to route tasks to the best available back-end model a good business move that keeps him using the bot. The background post from Elon Musk says the Grok bot will use the best back-end model for each task, including Claude Opus 5.5, Midjourney, Suno and other leading APIs.

AIAnthropic has launched the Anthropic Cyber Mission, which starts with the Critical Infrastructure Defense Program for operational technology and OSS Scanner for open-source projects. The defense program brings frontier Claude models, on-site engineers and threat research to trusted providers such as Accenture, CrowdStrike and Palo Alto Networks. OSS Scanner gives enrolled open-source projects periodic free scans from its strongest models, with reports sent without human review and an expected true-positive rate above 90%.

Why it matters: The announcement shows how a frontier AI lab is packaging cyber defense around critical infrastructure and open-source maintainers, including the program's partners and access routes.

AIAnthropic has published a 2026 update to its Usage Policy, taking effect November 12, mostly to clarify existing rules for longer, more autonomous Claude work. The changes consolidate deceptive-campaign prohibitions into a new section, narrow the elections rules to voter deception and disruption, and explicitly ban weapons-related software and surveillance tools. Requirements for high-risk uses and for models connected to autonomous physical hardware were also tightened.

AIAnthropic is committing $150 million over three years to the Genesis Mission, a federal initiative to accelerate scientific and technological discovery through AI. The funding will make Claude available to more than 15 participating agencies, including NASA, the National Institutes of Health, and the National Science Foundation. Over the next three years, Anthropic plans to provide Claude, Claude Code, and API credits to several hundred Genesis Mission research projects.

AIMicrosoft has repositioned Windows as the home for hybrid intelligence, where AI agents can run locally or in the cloud. The announcement covers four layers: MXC reaching general availability for agent isolation, local models such as MAI Code 1.1 Flash, Copilot on Copilot+ PCs gaining local context and actions in coming months, and new hardware including RTX Spark PCs and DGX Station for Windows.

AIThe main post notes that the 2020 scaling-laws paper is cited correctly as Kaplan and McCandlish et al., not Kaplan et al. The background post reports that Sam McCandlish has replaced Jared Kaplan as Anthropic's Responsible Scaling Officer, though the author expects no major change in RSP decisions.

AIThe item is a Chinese media report headlined as Claude solving a probability theory problem, described as a step toward Fields Medal-level mathematics. The feed supplied only a short excerpt, which quotes a Fields Medalist's remark dated August 30, 2026, so the full claim and details cannot be verified from this material.
