GigaToken: ~1000x faster Language model tokenization

πŸ’¬ HackerNews Buzz: 49 comments 🐐 GOATED ENERGY
🎯 SIMD optimization techniques β€’ Practical training efficiency β€’ Code performance potential
πŸ’¬ "Hardware is powerful, code inefficient... most libraries could be 10x-100x faster" β€’ "Tokenization is underappreciated, under-optimized part of agentic stack"

Sound Probabilistic Safety Bounds for Large Language Models

"We propose a novel framework for computing rigorous bounds on the probability that a large language model (LLM) generates harmful output to a given prompt. We study a new application of the Clopper-Pearson confidence intervals to obtain probably approximately correct (PAC) bounds for this problem. A..."

ResearchArena: Evaluating Sabotage and Monitoring in Automated AI R&D

"As AI agents begin to automate AI R&D, we need ways to assess whether their outputs are safe to deploy, even when the agents themselves may be untrusted. AI control offers one such approach: rather than trusting the agent, it treats it as a potential adversary and uses a monitor to detect covert sab..."

The safety failures we are not instrumenting: a perspective on hidden safety-critical challenges in modern AI systems

"Current AI safety discourse still focuses disproportionately on visible failures, including obvious harms, dramatic misuse, and hypothetical catastrophic scenarios. That focus is incomplete. In deployed systems, many of the most consequential failures are quieter: plausible rather than spectacular,..."

ISO: An RLVR-Native Optimization Stack

"Reinforcement learning with verifiable rewards (RLVR) is rapidly advancing the reasoning capabilities of language models, yet the optimization layer that converts reward feedback into weight-space updates remains poorly understood. Building on our prior analysis (Zhu et al., 2025), we study this mis..."

CircuitKIT : Circuit Discovery, Evaluation, and Application Toolkit for Mechanistic Interpretability

"Circuit analysis can support not only model explanation but also downstream interventions such as pruning, editing, steering, and selective fine-tuning. However, conducting such analyses currently requires stitching together separate implementations for discovery, evaluation, and intervention, as we..."

AdaFlash: Adaptive Speculative Decoding via On-Policy Distilled Diffusion Drafters

"Speculative decoding, in which a lightweight draft model first generates a draft sequence that is then verified in parallel by the target model, has become a prevalent paradigm for accelerating large language model inference. Recent work such as DFlash further boosts drafting efficiency by leveragin..."

🎯 Prompt engineering mastery β€’ Expert-AI collaboration β€’ User sophistication matters
πŸ’¬ "Words and sentences to an LLM are like witchcraft" β€’ "They are exploring the solution space with the same naivete, to some degree"
πŸ”¬ RESEARCH

The Ethics of Autonomous AI Agents for Offensive Security

"LLM-driven autonomous agents are reshaping offensive security. Unlike traditional penetration-testing tooling -- deterministic, narrowly scoped, and operated by trained practitioners -- agentic security tools exhibit \textit{indeterminacy} along three independent dimensions. First, their actions are..."

Copy Less, Ground More: Overcoming Repetitive Copying in Long-Context Reasoning via Evidence-Aware Reinforcement Learning

"Large language models that generate step-by-step reasoning traces have achieved strong performance on complex tasks, and extending them to long-context settings has emerged as an important frontier. However, we identify a critical failure mode in this regime: \emph{repetitive copying}, where models..."

Generative AI floods and dilutes the market for books

"Generative AI can produce book-length works of fiction at near-zero cost. These books are often dismissed as low-quality ``slop'' that buyers will ignore, and are assumed to carry little commercial weight. We test that assumption with full-text AI detection across 14,419 self-published genre-fiction..."

Prompt Design at Scale: How Format, Instruction Count, and Context Length Shape Instruction Adherence and Hallucination in Large Language Models

"Practitioners make three prompt-design decisions with almost no controlled evidence behind them: how to format instructions and context (markdown, plain text, prose, or tabular), how many simultaneous instructions a system prompt can carry before compliance degrades, and how much context a model can..."

PoTRE: Test-Time Reasoning inspired by Cognitive Heterogeneity

"While Large Language Models (LLMs) excel at many tasks, they frequently struggle with complex reasoning that requires long-horizon planning and iterative error correction. Furthermore, standard single-stream prompting proves brittle when models encounter novel abstractions or rigorous domain constra..."

Don't Trust the Label: License Laundering in AI Supply Chains

"AI artifacts move through a multi-platform supply chain, spanning datasets and models on Hugging Face and applications on GitHub. While each artifact carries a license whose obligations should propagate through redistribution, no study has yet measured whether those obligations survive the chain or..."

Off-Context GRPO: Learning to Reason on Hard Problems using Privileged Information

Inference-Time Steering for Cross-Lingual Factual Consistency in LLMs
