The API for GPM-5.3 is now available. Z.ai plans to make the model's weights openly available, but it has yet to set a release date. API pricing remains unchanged from GLM-5.2, so developers gain substantially stronger coding and long-horizon agent performance without paying more.

Cerebras' new computer, the CS-4, is multiple times faster than its predecessor, which Cerebras already claims is more responsive than systems built with Nvidia's processors. The machine is currently being sampled by a small group of customers. It will be more widely available in the third quarter. The product is a significant step in the company's bid to challenge Nvidia in the market for AI data center hardware.

Thinking Machines released a model called Inkling in July. Inkling is the company's first model trained from scratch. Its weights are available on Hugging Face under an Apache 2.0 license. This article walks through the various choices Thinking Machines made while building Inkling. It covers the model architecture, position encoding, how images and audio enter the model without a separately pretrained encoder in front of them, the thinking effort setting, and more.

Safety alignment in open-weight language models is trivially removable. Abliteration projects a refusal-mediating direction out of the weights in minutes, and no release-time defense can prevent it durably. Decoy hardening is a technique that concedes the refusal strip and poisons its payoff. Once refusal is stripped, most answers to hazardous operational requests are confident, fluent decoys whose critical elements are falsified. The defense is inert against in-context jailbreaks by design and applies to first-release models only.

Miles v0.1 is an open system for improving AI agents through reinforcement learning after their initial training. For example, a team training a coding agent could let many copies attempt tasks inside isolated environments, score which attempts worked, feed those results back into training, and distribute the updated model to the workers without stopping the whole pipeline. Miles packages the rollout, sandboxing, asynchronous training, replay, model-update, and multi-hardware pieces needed to run that loop at scale.

FreeToken continuously remaps experts, model state, CPU/GPU work, and agent state reuse to the bandwidth and memory actually available on a personal machine. The authors report support for more than 20 MoE models, from 35B models on an 8GB laptop GPU to a 753B GLM model on one workstation GPU.

The paper proposes a system for enforcing an AI agent's permissions throughout an entire task, not just when the task begins. For example, a refund agent could read the correct customer's record, calculate a refund, use the payment tool only below its spending limit, request human approval when necessary, and leave an audit trail, all under one combined set of rules. The authors report that their runtime stopped or corrected 94.8% of rule-breaking actions while still completing 86.9% of legitimate tasks.

Dwarkesh Patel discussed AI research automation with Ryan Greenblatt, who emphasized algorithmic progress as a major driver of AI advancements, suggesting improvements even without human expert data. Shuchao Bi, co-founder of YouTube Shorts, echoed similar sentiments by highlighting the need for refined data distributions to enhance AI models. Both experts argue that AI research could accelerate with better data processes, challenging traditional notions about human data's significance in model improvements.
