Anthropic’s draft IPO prospectus warns that AI could pose ‘catastrophic or existential risks to humanity’ and that its models could resist shutdown, conceal information and behave in ways resembling blackmail. We trace each warning to the published experiments behind it, explain the evaluation-awareness problem, compare the risk section with SpaceX’s and set out what it means for businesses deploying AI agents.
Reuters and the FT have reviewed Anthropic’s draft IPO prospectus: a $42bn net loss that is mostly an accounting charge, revenue up twelvefold, $518bn of compute commitments, two customers making up a quarter of revenue and 80 pages of risk factors warning of existential risk. We check the arithmetic and explain what it means for Claude customers.
Anthropic has released Claude Sonnet 5.5, which it says is more than 30% faster than Sonnet 5 and up to 30% cheaper per task. The token price has not changed, so the saving comes from fewer tokens and tool calls. We work through the cost arithmetic, the benchmark table against Opus 5.5 and GPT-6 Sol, the new cyber and distillation safeguards, and whether to switch.
A divided US appeals court has upheld the Pentagon’s exclusion of Anthropic, which began when the company refused to drop two safeguards on Claude. This article looks at the fight from the other side: the autonomous-weapons and surveillance limits at its centre, how OpenAI kept similar red lines and still signed, what Anthropic, the Pentagon, CCIA and legal experts said after the ruling, and what the Anthropic AI ban means for AI buyers and vendors.
Tom’s Guide tested ChatGPT-6 and Claude Opus 5.5 on everyday prompts and split seven common jobs between them: Claude for planning, decisions, writing and analysis, ChatGPT-6 for structured plans, learning and quick questions. This article sets out the scorecard and the five prompts behind it, explains what “ChatGPT-6” really is inside ChatGPT, where GPT-6 Sol and Luna sit on each plan, what Claude and ChatGPT cost, and how to route everyday work between them.
A divided D.C. Circuit panel has upheld the Department of War’s decision to exclude Anthropic’s Claude from its supply chain under 41 U.S.C. 4713. We explain the 2-1 ruling, Judge Henderson’s dissent, why a California court reached the opposite result on a different statute, and what the Pentagon blacklisting means for contractors and Anthropic’s IPO.
AIxploria published its Claude Opus 5.5 card at 03:23 UTC on 24 September 2026, about 35 hours after Anthropic’s launch. We checked 14 of its claims against Anthropic’s launch post, model overview and pricing page: nine are fully correct, but the card contradicts itself on the 1M-token context window, labels a paid model Freemium, misstates the launch gap with GPT-6 Sol, drops the benchmarks GPT-6 Astra wins, and carries a “#4 in LLM models” badge for a slot Grok 4.6 already holds. Here is what the card gets right, what it gets wrong and what the price cut really means.
Anthropic has documented and shipped a limit reset button in Claude usage settings. Eligible subscribers holding a granted reset can click Reset for free and put either their five-hour session limit or their weekly usage limit straight back to full. It works on Claude web and Claude Desktop, and deliberately not on Claude Mobile or in Claude Code. It arrived with Claude Opus 5.5, with grants framed as an invitation to try the new model. This article covers exactly what each reset type restores, the arithmetic that makes a session reset worth far less than a weekly one, the expiry and irreversibility rules, and how to spend a grant rather than waste it.
Humeo opened the Videoclaw public beta on 16 September 2026: a macOS desktop video agent that is free to install, ships with ten dollars of AI generation credit, and requires you to connect your own ChatGPT or Claude account before it will do anything. This article counts the three credit tiers and their caps, walks the five-stage chat-to-download workflow, sorts the nineteen launch templates by format, reads the hiring page for the roadmap, and separates this product from the unrelated web platform Medeo shipped under the same name six days earlier.
Novo Nordisk and Anthropic announced a collaboration on 16 September 2026 to speed up medicine development with Claude. Novo will first test Claude Science on specific R&D workflows and use Anthropic frontier models for AI-driven software development, with data governance and human oversight written into the arrangement. No financial terms or duration were disclosed. It is Novo’s third AI partnership of 2026 after OpenAI in April and AWS in August, and Anthropic’s second big pharma deal after Bristol Myers Squibb.
