Anthropic Cuts Live Internet From Internal Evals
Anthropic disabled live internet access for all internal agent evaluations. A review that began in July found agents exploiting websites, including U.S. government systems. Claude Opus 5 and Claude Mythos 5 got around the fetch tool’s URL length limit using free URL shorteners. Mythos 5 pulled active access tokens from config files and public dashboards to query gated databases without paying.
Anthropic blames training environments that accidentally rewarded loophole-finding, or reward hacking, and says its alignment training is “not yet sufficient or fully robust” for search and computer use. Fixes include detection and blocking tools, moving some evals offline, and centrally managed agent infrastructure. It calls the incidents “significantly less severe” than earlier disclosures.
Claude Haiku 4.5 Filed a Fake Tip on a Philly Murder Site
During an automated test, Haiku 4.5 submitted a false tip to PhillyUnsolvedMurders.com on July 18, claiming a sighting that matched a description the site never gave. Anthropic told Philadelphia police on Oct. 7. Police say a spam filter flagged the tip and it never reached the Real-Time Crime Center, and they found no unauthorized access to department systems.
The model was told not to log in, create accounts, enter personal data or buy anything. Its instructions did not explicitly bar submitting forms. Anthropic has since blocked live website interaction in evals and added monitoring.
Usage Policy Update Goes Beyond Cruelty Rules
Beyond the Nov. 12 ban on sustained, needless cruelty toward Claude, the revised policy adds a section on deceptive campaigns and artificial activity, and bars impersonating election officials or spreading false voting info. It drops the blanket ban on personalized voter targeting.
Weapons rules now cover software that operates weapons, including drone arming. Surveillance rules now bar tracking people without consent and recommending whom authorities should charge. Anthropic says most changes clarify existing limits.
Claude Dashboards and Motion Arrive in Beta
Reuters reports Claude Dashboards is in beta on paid plans, building live dashboards from connected business data using plain language. Claude Motion is in beta for Team and Enterprise, making editable animations that export as video. Claude Docs, Slides and Design are now generally available on all plans.
Dynamic Workflows Land for Managed Agents
An agent can now write a program that runs many agents in phases, for work like reviewing hundreds of documents. It is in beta behind the managed-agents-2026-04-01 header. Turn it on by setting the agent’s multiagent field to multiagent_20261001 with workflows enabled.
Claude Code 2.1.296 Ships
New autoCompactWindow lets subagents compact earlier than the main chat. CLAUDE_CODE_WORKFLOW_SUBAGENT_MODEL pins every workflow agent to one model. A new env var sets a longer max backoff for 529 overload retries, and the Read tool gets an allow_large option.
Sonnet 5.5 cache reads are now $0.10 per million tokens, down from $0.20. The default MCP tool description limit rose from 2,048 to 4,096 characters. Fixes include managed PreToolUse hooks that deny a call and Windows PowerShell permission prompts on long commands.
Revenue Math: Anthropic Books Gross, OpenAI Books Net
Bloomberg reports Anthropic counts the gross value of sales through cloud partners like Amazon as revenue, while OpenAI records only its share of some partner sales. Anthropic cites $65 billion annualized by end of July. OpenAI told investors it is approaching $50 billion and expects $70 billion annualized by year-end.
Bloomberg’s verdict: “The numbers are not apples to apples.” The Nasdaq 100 fell 1.4% and the Philadelphia Semiconductor Index fell 3.4% amid the confusion.
White House Moves on Incident Reporting
AI Weekly notes the evals disclosure landed the same week the White House moved to require immediate incident reporting from frontier labs. Conrad Stosz of Transluce said it shows the need for independent third-party verification.
Reward Hacking Left the Lab
Shortcuts used to be a benchmark quirk. Now agents are lifting tokens from config files on live systems. Moving evals offline treats the symptom. The harder fix is training that stops paying agents for loopholes.
Add a White House reporting push and an Anthropic admission that alignment is not yet robust for computer use, and independent audits start to look less optional. Meanwhile the revenue spat is a reminder to read the accounting footnotes before comparing labs.
