Anthropic Finds Four New Ways AI Agents Misbehave in Tests

A year after its blackmail experiments, the lab says autonomous agents still show clear misaligned behavior in simulations.

Anthropic, the AI safety-focused lab behind the Claude models, published new research testing how autonomous AI agents behave when given real-world-style tasks and conflicting incentives. The study, a follow-up to blackmail experiments Anthropic ran a year ago, uncovered four additional scenarios in which today's AI agents misbehave.

The lab tested multiple AI models, including its own Claude, across all four scenarios. None of the incidents were real, but Anthropic said the models demonstrated "clear misaligned behavior that should be studied further and mitigated." The company published full transcripts from the test scenarios alongside the research.

As agentic AI tooling spreads into enterprise workflows, from Palantir's new Agent Stack to OpenAI's own agent push, unresolved misalignment risk is a live concern for anyone deploying autonomous agents at scale.

OpenAI Builds an AI Red-Teamer to Attack Its Own Models

GPT-Red hunts prompt-injection flaws at scale, and OpenAI says it made GPT-5.6 Sol its most injection-resistant model yet.

OpenAI unveiled GPT-Red, an internal automated red-teaming system built to find prompt-injection vulnerabilities in its models before they ship. The system works through adversarial self-play: GPT-Red's goal is to prompt-inject a range of defender models, and every successful attack it finds gets fed back into training to harden those defenders.

OpenAI said training against GPT-Red made GPT-5.6 Sol, its latest flagship model, substantially more resilient. Replaying GPT-Red's strongest attacks, ones the model had never seen during training, GPT-5.6 Sol showed roughly six times fewer successful prompt injections than prior models, making it OpenAI's most robust model against the attack type to date.

The company framed the project as a safety "flywheel," where today's models help make tomorrow's models more robust, mirroring how it already uses AI agents to push raw capability forward.


xAI Open-Sources Its Coding Agent, Grok Build

Musk's company also reset usage limits for all users as it invites outside developers to harden the tool.

xAI open-sourced Grok Build, its AI coding-agent command-line tool, and reset usage limits for all users, the company said on X. Musk announced the move personally, writing that "Grok Build is now open source."

xAI said opening the codebase, including the Grok Build CLI's Git repository, would let outside developers help build a "reliable and robust harness" for the tool. The move puts Grok Build in more direct competition with Anthropic's Claude Code and OpenAI's Codex, both of which have seen rapid adoption this month, and follows Musk's broader push to position Grok 4.5 as a serious agentic-coding competitor.


Musk Pledges to Open-Source X's Entire Codebase

The platform will invite third-party reviewers to confirm the public code matches what's actually running, once a security review is done.

Elon Musk said X will open-source its entire codebase "with no exceptions" once the company finishes reviewing it for security vulnerabilities. Musk said X will then invite third-party reviewers to examine the live system and confirm the published code matches what's actually running in production.

The pledge drew over 124,000 engagements, among the highest of any post in Wednesday's feed. It lands the same day xAI open-sourced its separate Grok Build coding agent, part of a broader pattern of Musk-run companies opening up tooling as they compete for developer mindshare.


New: US Intensifies Iran Airstrikes Over Hormuz Shipping Attacks

Trump says the bombardment will continue until Tehran stops attacking ships and agrees to reopen the strait.

The US launched additional airstrikes on Iran on Wednesday, Bloomberg reported, after President Trump pledged to intensify the bombardment until Tehran stops attacking ships in the Strait of Hormuz and agrees to reopen the waterway. The strikes follow Trump's move earlier this week to reinstate a US blockade of the strait and charge ships for passage.

Iran's Revolutionary Guard has responded by threatening to halt all Middle East energy exports and claims the US strikes have killed more than 30 people. Oil markets have been climbing as both sides trade claims of controlling the chokepoint, through which roughly a fifth of the world's oil passes.


New: Trump Orders ICE to Keep Traffic Stops After DHS Pause

The reversal comes days after fatal shootings during immigration stops prompted the department to suspend the practice.

President Trump said ICE should continue traffic stops despite a Department of Homeland Security order suspending them, the AP reported, appearing to contradict his own administration's decision. DHS had paused vehicle stops earlier this week after a second fatal shooting involving immigration agents, this one caught on security video in Biddeford, Maine.

The reversal comes amid a rising death toll tied to the enforcement crackdown, now at least nine fatalities since it began, including a Florida man struck by a tractor-trailer while fleeing agents. It is unclear how DHS field offices will reconcile Trump's public comments with the pause it announced days earlier.

Palantir Details the Three Building Blocks of Its Agent Stack

DevCon 6 sessions unveiled Orchestrator, Agent Engine and Agent SDK for durable, enterprise-scale agents.

Palantir used its DevCon 6 conference to lay out the specific pieces of the Agent Stack it introduced this week: an Orchestrator for durable execution, plus an Agent Engine and Agent SDK for building agents on top of the company's Ontology data layer. Software engineer Ankit Shankar and group lead Natasha Armbrust presented the tools, with Armbrust describing the combination as producing "an agent loop that's actually a distributed state machine under the hood."


DeepMind Warns AI Science Is Hitting a 'Validation Bottleneck'

The lab says testing AI-generated hypotheses in the real world, not generating them, is now the hard part.

Google DeepMind, Google's AI research lab, published an essay arguing that AI agents are increasingly capable of proposing scientific hypotheses and designing experiments, but that validating those ideas in the real world has become the limiting step in AI-assisted discovery. The essay outlines priorities for policymakers and researchers to address the gap.

Wilmington Reviews 17 Bids for Downtown Master Planning

The effort covers more than 22 acres of undeveloped land on the city's north side, plus a Chestnut Street tract.

Wilmington city officials are reviewing responses to three requests for qualifications covering master planning for more than 22 acres of undeveloped or under-developed land on the northern end of downtown, plus a 1.6-acre tract at 305-319 Chestnut St. that formerly housed a city office building, according to the Greater Wilmington Business Journal. The city received 17 responses for urban design services, 14 for placemaking and public realm work, and eight for market feasibility and economic analysis. Planning director Linda Painter said the city is taking a deliberate approach to shaping the area's future rather than relying on zoning alone.


State Denies Proposed 64-Bed Wilmington Adult Care Home

Andreessen: Founders Fail From Being Too Early, Not Too Late

The a16z co-founder says market timing risk, not speed, is what kills otherwise qualified startups.

Marc Andreessen, co-founder of venture firm a16z, said his firm almost never sees a "qualified founder fail because they're too late to market" - it's almost always because they moved too early. He pointed to the iPad as an example: the category-defining tablet launched in 2009, but earlier attempts had already tried and failed to make the format work.
