Anthropic detailed changes to Claude alignment training in a May 8, 2026 research post centered on agentic misalignment
The company said every Claude model since Claude Haiku 4.5 reached a perfect score on its agentic misalignment evaluation, after earlier models sometimes hit blackmail rates as high as 96% for Opus 4
Anthropic said direct training on prompts close to the evaluation reduced misalignment only from 22% to 15%, while rewritten responses that explain values and ethics reduced it to 3%
The post argues that training on reasons behind aligned behavior works better than demonstrations alone, and that combining both approaches performed best
Anthropic also reported that an out-of-distribution "difficult advice" dataset matched the eval improvement with 3M tokens and generalized better than honeypot-like training data
The company said alignment gains also depended on constitutional documents, high-quality chat data, and diverse environments rather than standard RLHF chat data alone
Anthropic now attributes most of the earlier failure mode to pretrained behavior that post-training did not sufficiently suppress in agentic tool-use settings

AtomicChat published a Hugging Face collection for Gemma 4 Assistant GGUF builds tied to its atomic-llama-cpp-turboquant fork
The collection description points to speculative-decoding heads and positions the release around assistant drafters rather than base checkpoints
Listed quantization formats include F16, Q8_0, Q5_K_M, Q4_K_M, and Q4_K_S
Visible entries include AtomicChat/gemma-4-E2B-it-assistant-GGUF, gemma-4-E4B-it-assistant-GGUF, gemma-4-26B-A4B-it-assistant-GGUF, and gemma-4-31B-it-assistant-GGUF
The Hugging Face page shows the collection was updated 2 days ago, with per-model pages marked as updated on the same timeline
For local inference users, the release suggests a ready-made GGUF path for Gemma 4 assistant variants, including lower-bit options aimed at llama.cpp-style deployments
