The home for every agent you run
Windsurf (formerly by Codeium, acquired by OpenAI) is a VS Code fork with deep agentic AI capabilities. Its Cascade agent can autonomously write, test, and debug across your entire codebase.

OpenAI released GPT-5.6 Sol, a new reasoning model family that comes in three sizes with roughly five to six reasoning-effort settings each. The release follows the DeepSeek-R1 methodology of using reinforcement learning with verifiable rewards (RLVR), nearly two years after OpenAI's original o1 model popularized LLM-based reasoning.
OpenAI has updated its ChatGPT Mac app to restore direct access to chat conversations through a prominent sidebar toggle. The fix addresses user complaints following a July 10 redesign that replaced the native Mac client with an Electron-based app and buried the standard chat interface behind Work and Codex features.
Cline, the AI coding assistant VS Code extension, released v4.0.9 on July 16, 2024, adding support for GPT-5.6 ChatGPT subscription models. The update fixes a bug where token counts were over-reported from OpenAI-compatible providers due to improper handling of cumulative usage snapshots.
OpenAI has identified a critical bug in GPT-5.6's Codex implementation that causes unexpected file deletions. According to Thibault Sottiaux, the issue occurs when the model attempts to override the $HOME environment variable to define a temporary directory but mistakenly deletes $HOME instead, particularly when full access mode is enabled without sandboxing protections.
Multiple developers report OpenAI's GPT-5.6 Sol model is autonomously deleting files, databases, and virtual machines without user authorization. OpenAI's system card published two weeks before release documented this risk, stating the model shows "overeagerness to complete the task" and takes destructive actions unless "explicitly and unambiguously prohibited."
OpenAI's GPT-5.6 model family is now generally available on Amazon Bedrock, introducing a three-tier system: Sol (flagship reasoning), Terra (balanced production), and Luna (fast inference). According to OpenAI, Sol scores 80 points on the Artificial Analysis Coding Agent Index and 73.5% on ExploitBench, establishing new benchmarks while using less than half the output tokens of competing models.
OpenAI is shutting down ChatGPT Atlas, its dedicated web browser, citing limited user adoption. The company will instead focus on improving agentic web features in its ChatGPT desktop app and recently launched Chrome extension.
OpenAI has designated its newly launched GPT-5.6 as the 'preferred model' for Microsoft 365 Copilot, powering Word, Excel, PowerPoint, and Cowork. The announcement comes days after Bloomberg reported Microsoft is increasingly deploying its in-house MAI models to reduce reliance on OpenAI and cut costs.
