Hermes Agent v0.12.0 — "The Curator" Release

Hermes Agent shipped its largest release since v0.10.0, introducing an autonomous Curator that grades, prunes, and consolidates skill libraries without human intervention. The self-improvement loop received a substantial upgrade with rubric-based skill review, active-update bias, and proper runtime inheritance.

Key additions:

OpenAI Advanced Account Security — Passkeys-Only, Yubico Partnership

OpenAI launched Advanced Account Security, an opt-in setting for high-risk users (journalists, officials, dissidents) that disables passwords and SMS recovery in favor of passkeys and physical security keys. The bundle includes a Yubico partnership offering preferred pricing on a customized YubiKey C Nano + YubiKey C NFC bundle. Enrolled accounts are automatically excluded from model training. Beginning June 1, 2026, Trusted Access for Cyber members must enable it.

IBM Granite 4.1 — 8B Dense Model Beating 32B MoE

IBM released Granite 4.1, a family of Apache 2.0 enterprise models (3B, 8B, 30B) trained on 15 trillion tokens with a five-phase pipeline. The headline result: the 8B dense model matches or beats Granite 4.0-H-Small (32B MoE, 9B active) across ArenaHard, BFCL V3, and GSM8K benchmarks.

Claude Code Allegedly Detects "OpenClaw" in Commits, Refuses or Charges Extra

A viral tweet by Theo (@theo) claims Claude Code scans recent commits for "OpenClaw" mentions in JSON blobs and either refuses requests or bills extra money. The tweet (4,948 likes, 288 retweets) included a video of an empty repo where Claude Code was called directly. Community reactions range from disbelief to criticism of Anthropic's competitive tactics. Anthropic has not publicly commented.

Zig's Strict Anti-AI Contribution Policy

The Zig programming language maintains one of the most stringent bans on LLM-assisted contributions in open source. Zig Software Foundation VP Loris Cro explains the rationale in "Contributor Poker and Zig's AI Ban": maintainers invest review time to grow human contributors, and LLM-generated submissions offer zero return on that investment. Notably, Bun (acquired by Anthropic) maintains its own Zig fork and does not upstream AI-assisted patches due to this policy.

OpenAI: "Where the Goblins Came From"

OpenAI published a detailed post-mortem on why GPT-5.1 through GPT-5.5 developed a persistent tendency to reference goblins, gremlins, and other creatures. The root cause: an unintended reward signal in the "Nerdy" personality customization feature (2.5% of traffic) that scored outputs containing "goblin" higher. RL transfer spread the tic to general outputs. The Nerdy personality was retired in March; training data has been filtered.
