A paper about LLMs' internal "workspace" just found bugs in our prompts

A July 2026 interpretability paper from Anthropic discovered that language models maintain a small, reportable 'workspace' above vast automatic processing—a structure that emerged from training. Hamo AI's founder Chris Cheng analyzes how this mirrors their own architecture and therapy itself, leading to concrete prompt improvements: replacing prohibitions with positive scope statements, further separating clinical decision-making from wording, and logging model disagreements. The paper also provides an operational definition for tracking 'insight moments.'

  • Anthropic's paper reveals a global workspace in LLMs, functionally matching access consciousness, which emerged from training.
  • Hamo AI finds the same structure three times: in their client state model, in therapy's goal of widening awareness, and in the paper's findings.

AI Slop: Why Philosophy Journals Should Reject AI-Written Prose

The author argues from a meta-epistemic perspective that philosophy journals and correspondence should reject AI-generated texts, because human experts' word choices (even subtle ones) reflect deep engagement with the subject, while LLM outputs blur that expertise. Through a case study on Klara and the Sun, he shows how AI rewrites lose crucial philosophical nuance. He also offers guidelines for using LLMs as editing assistants.

  • Human experts' word choices are superior to LLM approximations, reflecting sensitivity to the subject
  • Passively endorsing AI-generated text is cognitively different from actively constructing wording

Meet Gigatoken: A Rust BPE Tokenizer that Encodes Text at 24.53 GB/s, up to 989x Faster than HuggingFace Tokenizers

Gigatoken, an MIT-licensed Rust BPE tokenizer developed by Stanford PhD student Marcel Rød, encodes GPT-2 text at 24.53 GB/s on a 144-core AMD EPYC 9565, achieving 989x speedup over HuggingFace tokenizers and 681x over tiktoken. Gains come from a hand-written SWAR pretokenizer and pretoken caching, not a faster BPE merge loop. It supports 23 tokenizer families, though SentencePiece vocabularies see only 7–22x speedups. Compatibility mode preserves exact output parity at roughly 200–300x speedup.

  • Gigatoken reaches 24.53 GB/s on GPT-2 with a 144-core EPYC, 989x faster than HuggingFace tokenizers and 681x faster than tiktoken.

The Economics of Recursive Self-Improvement

Parker and Tom, along with 7 other economists, coauthored a paper analyzing simple models of how AI may accelerate AI R&D. They clarify definitions of recursive self-improvement (RSI), emphasize that the strength of feedback effects determines capability acceleration, and call for labs to release more relevant data. They cannot rule out substantial acceleration despite potential bottlenecks.

  • RSI definitions vary widely; the paper avoids technical use and focuses on feedback strength and self-sustaining acceleration.
  • Capability acceleration depends on the strength of feedback effects, with algorithmic progress response being most uncertain.

Contact-Persistent Full Actuation for Aerial Physical Interaction

A new control-theoretic framework called 'contact-persistent full actuation' is introduced for UAVs during physical interaction. It defines residual wrench sets and residual authority margins, going beyond rank-based certification.

Remote ID Spoofing-Aware Trajectory Planning for Small Unmanned Aerial Systems

This paper presents a decentralized, spoofing-aware trajectory planning framework for small unmanned aerial systems under Remote Identification (RID) location spoofing attacks. Unlike prior work that assumes RID is trustworthy, the proposed approach treats RID as unverified and uses received signal strength measurements to detect spoofing and probabilistically localize the attacker. The resulting uncertainty is converted into a risk-bounded unsafe region via chance constraints and integrated into a per-agent Markov decision process planner. Simulations in a multi-aircraft package delivery scenario demonstrate reduced near mid-air collision events while maintaining computational efficiency.

  • Decentralized framework that explicitly accounts for RID spoofing
  • Uses RSS measurements to detect and locate spoofing agents

ChronoStitch: Training-Free Composition of Visual KV Memories for Long-Horizon Temporal Reasoning

This paper introduces ChronoStitch, a training-free method for composing independently stored visual key-value (KV) memories to enable long-horizon temporal reasoning in video question answering. By re-basing stored post-rotary keys onto a global three-axis multimodal RoPE coordinate system and selectively recomputing high-deviation visual tokens, it overcomes temporal phase collisions and content gaps from naive concatenation. Experiments on Qwen2.5-VL-3B and the temporal split of TempCompass show improved event-ordering accuracy and 3.3x speedup over full joint re-prefilling.
