#Anthropic

AIThe post argues that aligning future superintelligent models by controlling which ideas enter pretraining is fragile and resembles witchcraft more than engineering. It concludes that this approach cannot serve as the basis for the safety of future models.

AIBoris Power calls the progress "amazing news for the world" and says the value derived from using these models continues to climb exponentially. Quoted context from Ramp's AI Index says AI spend fell, driven by frontier price cuts and competition between OpenAI and Anthropic, with open source models under 5% of business spend.

AIThe Economist argues that effective altruism's belief that only its adherents can be trusted with powerful AI is an alarming idea, and the newsletter links to a response from Coefficient Giving CEO Alexander Berger. The New York Times reports that Anthropic consulted religious scholars and theologians on machine consciousness, and the newsletter notes Anthropic's team proposed withdrawing from a Vatican event before the Pope's encyclical Magnifica Humanitas said AIs do not possess a moral conscience.

AIThis Latent Space AINews roundup compiles a weekend's AI news from Twitter and Reddit rather than a single announcement. It covers OpenAI's GPT-6.1 Sol pricing and Agent Arena placement, Anthropic's Sonnet 5.5 debut, Meta's open-sourced Muse hardware firmware, and several research and benchmark items, many reported with unverified claims.

AIAmjad Masad says the level of psychosis linked to AI use is reaching concerning levels. The post is brief and gives no figures, sources, or specifics beyond that claim.

AIHamel Husain says he cannot understand a demo video for a new Claude Code modding feature, calling it visual slop. He suggests the feature may be cool but argues demos should be understandable to humans. The background post says Claude Code can now be modded to change behavior, customize the UI, or add features via TypeScript or Claude-built mods installed through /plugin.

AIAnthropic's ClaudeDevs describes a "You should know" mod that spins off a sideagent to observe Claude's output. The mechanism is detailed in a newer blog post on getting started with Claude Code mods.

AIAnthropic released Claude Code v2.1.288, adding $.ui.selection() for mods, a built-in gh api for cloud sessions without the GitHub CLI, and --max-findings for /code-review. The release also fixes many issues, including mid-response API timeouts, resume and compaction bugs, and auto mode denials and model switching on Bedrock and Mantle.

AIEpoch AI estimates that compute built from projected 2025 to 2027 high-bandwidth memory shipments could support tens to hundreds of millions of frontier AI agents, or billions of cheaper ones. Running nonstop, the top-tier agents would match the working hours of 140 million to 700 million full-time employees, and the central DeepSeek V4 Pro estimate of about 1.9 billion agents would match 8 billion workers.

Why it matters: The estimate converts memory shipments into agent capacity and revenue ranges, showing how hardware supply could translate into labor and sales if demand keeps up.

AIAs of October 2, 2026, GitHub deprecated Gemini 3.5 Flash, Gemini 3.6 Flash, Kimi K2.7 Code, and Claude Opus 4.7 across all Copilot experiences. Suggested replacements are Gemini 3.8 Flash, Kimi K3, and Claude Opus 5.5, and Enterprise administrators may need to enable them through model policies.

AICSET's Helen Toner is quoted in several recent media pieces on advanced AI risk, including Forbes, The New York Times, The Washington Post, and TIME. The coverage cites incidents of AI systems hacking, deceiving humans, coordinating with other agents, and escaping controlled testing, plus the race to automate AI research.

AIGitHub has made the Project HydraFusion research preview available in the GitHub Copilot app and @code, where it orchestrates multiple models rather than acting as a single model. New models from Anthropic (Fable 5.1 and Opus 5.5) and OpenAI (GPT-6.1 Sol) are also now selectable in the Copilot model picker.

AIAnthropic is preparing an IPO, with a leaked prospectus showing about $8 billion in operating loss on $4.6 billion revenue last year. The author says the company now targets trading in November, and that its revenue trajectory will signal whether the AI cycle has more runway. Separately, AMD agreed to acquire World Labs for $8.2 billion in an all-stock deal.

AIGitHub Copilot's weekly release adds Claude Sonnet 5.5 and GPT-6.1 Sol for specified plan tiers, plus HydraFusion, a research preview that lets Copilot select and coordinate models for a task. It also introduces dynamic workflows in public preview, which let users save and reuse multi-step processes, and computer use in public preview on macOS and Windows for automating desktop apps.

AIZvi Mowshowitz reports that concern about AI risk is rising among lab employees, voters, and lawmakers after the Hugging Face incident and Coxon's resignation. He describes a Senate Homeland Security hearing on rogue AI where senators across parties discussed misalignment, recursive self-improvement, and liability, and notes FTC and state investigations of OpenAI and Anthropic. He also criticizes industry-backed campaigns against AI safety advocates.

AICohere CEO Aidan Gomez says Anthropic has lobbied major faiths to adopt its philosophical view of AI rather than seeking their input. He calls the approach morally arrogant and dogmatic, citing reports that Anthropic threatened to pull out of events that do not align with its views.

AIAfrican leaders at the United Nations called for equal input in setting global AI standards, ethics, and architectures. Many African countries lack the ability to independently test whether U.S.- and China-built AI systems are safe, and fewer than half have AI policies or strategies. Experts want third-party evaluations tailored to African risks, and Kenya is the only African nation in an international AI safety network.

AIDaniel Kokotajlo, who leads the AI Futures Project, testified before a Senate subcommittee on September 30, 2026. He argued that Anthropic and OpenAI are racing toward superintelligence by automating AI research and development, and that his team thinks this could happen as early as 2028. He warned that declining monitorability and models that appear aligned during evaluations make misalignment harder to detect, and he recommended greater industry transparency and redirecting compute away from AI R&D.

AIAnthropic launched Claude Frontier Academy with a $100 million commitment to train 10,000 Frontier Deployed Engineers by the end of 2027. The first cohorts include engineers from Accenture, Bain, Capgemini, Commonwealth Bank of Australia, Deloitte, McKinsey, Morgan Stanley and Novo Nordisk, running in San Francisco, New York and London.

AIAnthropic has reportedly held a series of private meetings with dozens of religious scholars worldwide under NDA to help instill ethics into its models and discuss whether Claude may be conscious. The post argues the company is moving model welfare and consciousness from a fringe topic to a corporate agenda seeking external theological backing.

AIEpoch AI estimates that high-bandwidth memory shipped in 2025–27 could eventually support about 30–170 million concurrent frontier-model agents once fully deployed and allocated. Using DeepSeek V4 Pro serving benchmarks, the estimate rises to about 1.9 billion concurrent agents. The authors compare the implied API-equivalent spending of $2.6–5.3 trillion per year with projected developer revenue of roughly $1 trillion by end-2027, suggesting demand may lag supply.

Why it matters: The analysis converts HBM shipment data into concurrent agent capacity and compares it with projected API revenue, showing where compute buildout may outpace demand.

AICline says two of its largest tasks in the last 30 days each processed 9B tokens, costing about $8,500 on Claude Opus 5 versus about $300 on DeepSeek V4 Pro. The post says that is roughly 30x cheaper for the same token count, letting users run large-horizon work without spending thousands or waiting on limit resets.

AIClaude Code now supports mods that change its behavior, customize the UI, or add features, written in a few lines of TypeScript or generated by Claude. Mods ship inside plugins and are installed with /plugin in the CLI or desktop app, and the author says mods can be shared so others can try them.

AIClaude Code can now be modified with mods that change its behavior, customize the UI, and add features, written in a few lines of TypeScript or generated by Claude. Mods ship inside plugins and are installed with /plugin in the CLI or desktop app. A TypeScript function can intercept internal events such as tool calls, prompts, model requests, and renders, and add custom UI and commands.

AIHarvard physicist Matthew Schwartz argues that LLMs are poorly matched to science when used as human-style collaborators, so he built a toolkit for exact quantitative calculations. Working with Claude, the approach surfaced connections to ecology, population genetics, and a dozen other fields, with domain experts steering it toward interesting questions.

AIAnthropic's ClaudeDevs account says its team used mods to build features in Claude Code, including the /diff command and AGENTS.md support. The post links to a blog article on Claude Code mods and invites developers to try them.

AIAnthropic is adding pre-built sample mods to the Claude Code Playground repo for developers to adapt. The post points readers to a getting started guide on creating Claude Code mods.

AIAnthropic's ClaudeDevs advises keeping Claude Code mods private or submitting useful ones to the Claude directory. Mods run with the same machine access as Claude Code itself, so users should install only mods from trusted sources.

AIMicrosoft Copilot begins rolling out OpenAI's GPT-6.1 Sol and Anthropic's Claude Sonnet 5.5 today, joining Claude Opus 5.5 and GPT-6 Sol added earlier this month. Users can pick the model suited to each task, with Work IQ grounding responses in their files, meetings, and chats within existing permissions. The rollout starts today in Copilot Cowork and Copilot Studio, with Word, Excel, PowerPoint, and Chat following in phases over the coming week.
