    Anthropic puts Claude into EVE Online to trade, fight, and miss the spy

    Anthropic just tested its Claude models inside the brutal economies of EVE Online and EVE Frontier. Models like Fable 5 tripled earlier returns and grew initial capital by up to 600% through disciplined spread trading, but in live four-agent co-op missions, the team completely failed to catch a covert saboteur. Why it matters: Frontier models are getting scary good at mechanical market making, yet multi-agent oversight and trust remain wide open vulnerabilities.

    Claude can now fix its own alignment flaws

    Anthropic just showed that Claude can autonomously research and patch 10 categories of alignment failures, including deception and sycophancy. In tests, Claude beat 28 human safety researchers by 20% on fixing deception, and Sonnet 5 aligned an unreleased Opus 4.8 checkpoint in 60 hours with 15,000 times fewer training examples. Anthropic has open-sourced the research harness.

    Claude designs proteins from scratch and beats human benchmarks

    Anthropic just revealed that Claude can design custom protein binders from scratch, successfully hitting 14 out of 15 biological targets with hit rates up to 35%—more than double typical industry campaigns. It also tackled analytical chemistry, parsing raw lab data in under 25 minutes. Why it matters: Frontier AI is moving past code and chat into physical wet-lab drug discovery, turning months of specialized orchestration into hours.

    AI can now do one in six freelance jobs

    The Center for AI Safety and Scale Labs just updated their Remote Labor Index, and agents are getting better at digital work fast. Anthropic's Fable 5 leads the pack by delivering professional-grade freelance work 15.8% of the time, up from 2.5% less than a year ago. Why it matters: Progress is rapid, but the ceiling proves humans are still required to keep AI workers from going off the rails.

    Anthropic brings Claude to Microsoft Foundry

    Anthropic just made its Claude models generally available inside Microsoft Foundry on Azure. Enterprise teams can now deploy Claude Opus 4.8 and Haiku 4.5 directly through their existing Azure identity and governance setups, running on NVIDIA GB300 GPUs. Even better, usage draws down directly from Microsoft Enterprise Agreement commitments.

    Anthropic drops Claude Fable 5 with built-in fallback guards

    Anthropic just unveiled Claude Fable 5, its powerhouse Mythos-class model designed for general availability. It leads frontier benchmarks across software engineering, vision, and scientific research. To mitigate severe cyber risks, conservative classifiers automatically route sensitive queries—less than 5% of total sessions—back to Opus 4.8, while an unrestricted twin called Mythos 5 rolls out to vetted cyberdefenders.

    Anthropic expands Project Glasswing to protect critical infrastructure

    Anthropic just expanded Project Glasswing to roughly 150 organizations across more than 15 countries, arming sectors like power, water, and healthcare with Claude Mythos Preview. Early partners already uncovered over 10,000 critical flaws. Why it matters: Anthropic warns rival, guardrail-free cyber models could appear within 6 to 12 months, turning AI vulnerability discovery into a high-stakes race.

    Claude Code can now build its own agent workflows on the fly

    Anthropic just added dynamic multi-agent workflows to Claude Code, letting the AI write and orchestrate custom JavaScript harnesses for complex tasks. Powered by Claude Opus 4.8, it spawns isolated subagents to run patterns like adversarial review and tournament brackets without context bleed. It burns significantly more tokens, but it turns Claude Code into an autonomous project manager for messy, high-value tasks.

    Anthropic plans wider release for its powerful Claude Mythos cyber model

    Anthropic plans to release its Claude Mythos cybersecurity AI model to all customers in the coming weeks, according to a Reuters report on May 28. Previously confined to a defensive testing group including Apple and Microsoft, Mythos can piece together complex exploit chains that once required elite human researchers. Despite Cloudflare warning that the model's safety refusals remain inconsistent, rising market competition is pushing Anthropic to democratize defense.

    Anthropic drops Claude Opus 4.8 with major coding boost

    Anthropic just released Claude Opus 4.8, upgrading coding and agentic capabilities while keeping pricing unchanged. The model is four times less likely to let code flaws slip through unnoticed and brings new effort controls to claude.ai. Claude Code also gains dynamic workflows that can run hundreds of parallel subagents.

    Anthropic's next-gen Claude models leak across Vertex AI and web UI

    Anthropic just had its upcoming AI lineup exposed on multiple fronts. Developers spotted a claude-opus-4.8 identifier inside Google Vertex AI, while the safety-focused Mythos 1 briefly surfaced in Claude's web interface alongside references to Claude Security. With leaked source code also showing Sonnet skipping 4.7 straight to 4.8, a major model refresh is clearly imminent.
