OpenAI has published an announcement stating that starting in December, users of the Plus, Pro, and Business subscription plans will share a unified usage allowance between ChatGPT and Codex, against the backdrop of bringing Work's agent capabilities into the main ChatGPT experience. Usage in both places is measured uniformly in Tokens, and the rate of consumption depends on the selected model and task complexity; Instant Chat does not consume the allowance. Users can view their combined remaining allowance and next reset time in Settings → Usage; after the allowance is exhausted, they can wait for automatic reset, upgrade their subscription, or purchase additional Credits.

Around October 27, Anthropic's Claude Code pushed new rules via server-side updates: Claude can help users make original games or games of a certain genre, but no longer replicates a specific existing game, even if the name is changed or it claims to be original. Claude Code developer Addy Osmani responded that this was adding two sentences to Opus 5.5's prompt, based on the existing intellectual property usage policy, and acknowledged that the boundaries are still being explored, and that legitimate requests wrongly rejected can be sent to him. The original article points out that this is a soft constraint at the prompt level, which can be circumvented by describing gameplay, and that scenarios such as fan remakes and ports of old games may be wrongly affected.

The DeepSeek Harness team published a technical article on its official WeChat account, proposing an Agent form and system architecture called Super-agent. Through designs including a dual-layer architecture, event-driven operation, asynchronous multi-channel interaction, storage-compute separation, and an external Watchdog, it enables the Agent to maintain context across sessions and advance multiple tasks in parallel. The architecture has four basic characteristics: continuous, efficient, proactive, and persistent, and users can interact with the same Agent through interfaces such as IM chats and GitHub comments. The team said that internal instances built on this approach are already running continuously, participating in issue reproduction and fixing, code review responses, and the iteration of DeepSeek Harness itself.

Browser Use has opened its fastest browser agent, BU Ultrafast, from the waitlist to all Cloud plans in the US, including the free tier. Official data shows a median task time of 22 seconds and a cost of $0.0064 per task, compared with 79 seconds and $0.0098 for the default agent on GPT-6 Luna. To use it, simply set model to bu-ultrafast; if you need more step-by-step reasoning, you can switch to bu-fast from the same agent, which is billed at standard rates.

The DeepSeek Harness team published a technical article titled "Super-agent Design Exploration: Toward a More Autonomous Agent System," proposing a dual-layer architecture, event-driven design, asynchronous multi-channel interaction, storage-compute separation, and an external Watchdog to break through the scale limits of multitasking and team collaboration. The team said that an internal Super-agent instance built on this approach is already running continuously, routinely participating in issue reproduction and fixes, code review responses, and DeepSeek Harness's own iteration; when members report software issues in group chats, even if no one @s the AI, it can identify potential defects and attempt in the background to reproduce them and find fixes.

At its media open day, Iluvatar CoreX opened a live demonstration of the Tianyao 300 for the first time; in an on-site random-question comparison, the Tianyao 300 took 95.6 seconds while Nvidia's H200 took 112 seconds. Third-party testing in July this year showed that under PD-disaggregated deployment, the Tianyao 300's converted single-card end-to-end throughput reached 1.05 times that of the H200, and the per-card effective throughput of an 8-card full machine under FP8 training reached 1.33 times that of the H100. The same event also showcased the AFD disaggregation solution, the IXL144 super node and the Tongyang TY1200 on-device terminal, and previewed the next-generation on-device product TY2000 with a nominal computing power of 600T.

Anthropic announced that eligible Claude Ultra subscribers will no longer have the 5-hour usage window limit and can use the service continuously within their weekly quota, which remains 10 times that of Pro users. The former Max 20x tier has been renamed Ultra, while Max 5x has only had its name simplified, with no notable changes to pricing or rules. New accounts must pass an automated verification based on account and payment history, and users can check whether the 5-hour progress bar has disappeared on the Usage page in Settings. Mike Overell, Anthropic's head of subscription products, apologized for the misunderstanding caused by the previous inconsistency between the 20x window quota and the 10x weekly quota in the naming.

Anthropic has renamed the Claude subscription's Max 5x and Max 20x to Max and Ultra respectively, with prices unchanged at $100 and $200 per month. Ultra users who meet verification conditions will have the 5-hour usage limit removed and can use the service continuously within their weekly quota, which remains 10 times that of Pro users. Mike Overell, who is responsible for the Claude subscription product at Anthropic, explained that the "20x" in the former Max 20x referred to the quota for a single 5-hour window, which was inconsistent with the weekly 10x quota and prone to misunderstanding, and he apologized for previous communication issues.

Daxiao Robotics recently partnered with the S-Lab at Nanyang Technological University to release Mundo, a world model built for specific environments that supports scene reconstruction, free-viewpoint exploration, and spatiotemporal simulation. By inputting 1 to 12 images, it can generate an explorable 3D scene around room furniture and spatial structure; the same set of reference images can support multiple camera paths, and in large scenes it can continuously generate frames ranging from tens of seconds to minutes. Mundo also configures physical properties such as mass and friction for objects through scene programs, with a physics engine computing push-and-collision responses, and supports robots practicing navigation and manipulation in the same scene, complementing its world model technology system centered on Kairos.
