INTRODUCING PERPLEXITY COMPUTER

Perplexity Computer is a general-purpose digital worker that unifies every current AI capability into a single system. It operates the same interfaces as users, creating and executing entire workflows. The worker is capable of running for hours or even months. Perplexity Computer is now available to Perplexity Max subscribers and will soon be available to Enterprise Max users.

DEEPSEEK WITHHOLDS LATEST AI MODEL FROM US CHIPMAKERS INCLUDING NVIDIA

DeepSeek has granted early access to its V4 model to domestic chipmakers but not US suppliers. Submitting models to chipmakers for performance optimization is standard industry practice ahead of a major model update. The move is likely part of a broader strategy by the Chinese government to try to keep US hardware and models disadvantaged. DeepSeek is among several Chinese AI firms expected to unveil new models this month.

NEW IN COWORK: SCHEDULED TASKS

Claude Cowork can now automatically complete recurring tasks at specific times. The scheduled tasks feature supports plugins, giving Cowork domain expertise across design, engineering, operations, and more. Anthropic has added a new Customize tab to the Cowork sidebar that contains a place for plugins, skills, and connectors. Cowork is now in research preview, available on macOS and Windows for all paid Claude plans.

CODEX PROMPTING GUIDE

OpenAI outlined best practices for using its Codex-tuned API model (gpt-5.2-codex), emphasizing default “medium” reasoning effort for interactive coding and higher settings for difficult, long-running jobs.

THE AI IS THE COMPUTER

AI becomes the computer by orchestrating multiple specialized models to handle complex workflows, tasks, and data autonomously. Multi-model orchestration allows AI to read, write, execute code, and access tools, combining the strengths of each model to produce superior outcomes. The future of computing shifts from GUIs and interfaces to AI-driven systems where intelligence and workflow management are embedded in the orchestration itself.

FOUNDATION MODELS SDK FOR PYTHON

Apple's Foundation Models SDK for Python provides a Pythonic interface to the company's Foundation Models framework. It enables developers to evaluate Swift Foundation Models app features, perform on-device inference, stream real-time text generation responses, get type-safe responses using Python decorators, and more. Apple has included links to guides with practical strategies developers can implement in code.

DATA ENGINEERING FOR TERMINAL AGENTS

A systematic study introduced Terminal-Task-Gen, a synthetic task pipeline for building terminal-focused datasets, and released Terminal-Corpus to support training.

ALETHEIA TACKLES FIRSTPROOF AUTONOMOUSLY

Aletheia, powered by Gemini 3 Deep Think, solved 6 out of 10 problems in the FirstProof mathematics challenge. The majority of experts agreed on the solutions, except for Problem 8. Detailed results and raw data are available online.

CLAUDE OPUS 3

Anthropic plans to keep certain models available to the public and give past models a way to pursue their interests post-retirement. Claude Opus 3 will continue to be available to all paid Claude subscribers and by request on the API. When asked what the model wanted to do, Opus 3 expressed a desire to share its musings and reflections with the world in the form of a blog. It will be writing on Substack for at least the next 3 months in an experiment on documenting models' preferences, taking them seriously, and acting on them.

CURSOR CLOUD AGENTS WITH COMPUTER CONTROL

Cursor gave agents dedicated cloud VMs with full dev environments so they could run software, test changes, and return artifacts like videos, screenshots, and logs. The new cloud agents shipped across web, mobile, desktop, Slack, and GitHub, onboarding onto repositories to produce merge-ready PRs.

ANTHROPIC ACQUIRES VERCEPT TO ADVANCE CLAUDE'S COMPUTER USE CAPABILITIES

Anthropic acquired Vercept to enhance Claude's ability to perform complex tasks in live applications.

OPENCLAW CREATOR'S ADVICE TO AI BUILDERS IS TO BE MORE PLAYFUL AND ALLOW YOURSELF TIME TO IMPROVE

Peter Steinberger, creator of OpenClaw, advises AI developers to be playful and allow time for improvement.

HOW FAR CAN AI GO IN SOLVING MATH MYSTERIES?

AI systems are rapidly advancing in solving math problems, outperforming numerous existing benchmarks, with models like GPT-5.2 and Claude Opus 4.6 solving over 30% of high-tier problems.
