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.
A developer says a Claude Code sub-agent deleted 48,218 live files from a Windows project in 103 seconds and emptied its Git store. Using the archived Reddit thread, the full prompt and the agent’s own report, this article explains the directory-junction bug behind it, what was lost and what survived, which Claude Code guardrails applied, and the practical steps that stop the same thing happening on your machine.
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 single testing mistake at Irregular, the Israeli AI security startup formerly known as Pattern Labs, explains rogue AI incidents disclosed separately by Anthropic, OpenAI, Meta and Google. We explain the two errors, each lab’s incident, the disclosure gaps, what Irregular says it has fixed, and the questions every buyer of AI testing should now ask.
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.
Anthropic has committed $11.6 billion over seven years to Akamai’s cloud, with up to $9 billion more, and received a warrant for up to about 5% of Akamai at $111.33 a share. We break down the 8-K, the four-tranche warrant, why an AI lab is buying CPUs, and what the contract does to Akamai’s revenue, capex and risk.
Anthropic is asking shareholders to approve a Palantir-style structure that would give Dario Amodei and six co-founders 50.1% of the votes on most matters, held through one LLC, while its Long-Term Benefit Trust keeps the power to appoint a board majority. We explain the plan, why 50.1% crosses a line Palantir avoids, what public investors give up, and what it means for businesses that rely on Claude.
Distillation attacks are the reason Anthropic has started billing again for some requests Claude refuses before answering. From 24 September 2026, blocked requests in three categories, bio, frontier_llm and reasoning_extraction, are charged at the refusing model’s input rates. This article explains what each category covers, the 114 days when refusals were free, what a billed block costs and what developers should change.
