OpenAI is releasing a set of open-source prompts developers can use to make their applications safer for teens. The policies, designed to work with OpenAI's gpt-oss-safeguard model, address graphic violence, sexual content, harmful body ideals, dangerous activities, and age-restricted goods.

Anthropic has released 'auto mode' for Claude Code, a permissions system that sits between conservative defaults and fully disabled safeguards. The feature uses a classifier to automatically approve safe actions like file writes and bash commands while blocking potentially destructive operations.

Anthropic has added "channels" to Claude Code, enabling Claude to respond to incoming messages, webhooks, and notifications asynchronously without user intervention. The research preview supports Telegram and Discord with custom channel support, running through MCP servers with two-way communication.

OpenAI has acquired Astral, the company behind widely-used Python development tools Ruff, uv, and ty, which see hundreds of millions of downloads monthly. The tools will integrate with OpenAI's Codex platform to enable agentic AI systems that can plan changes, modify codebases, run tools, and verify results. OpenAI commits to keeping the tools open source under permissive licenses post-acquisition.

Google Deepmind has expanded the Gemini API to enable multi-tool chaining, allowing developers to combine built-in tools like Google Search and Google Maps with custom functions in a single request. Results from one tool now automatically pass to the next through context circulation, eliminating the need for separate sequential handling.

OpenAI Codex subagents reached general availability after weeks of preview, enabling developers to define custom agents as TOML files and parallelize task execution. The feature mirrors Claude Code's implementation with default subagents for exploration, worker, and default operations.

OpenAI has released Codex Security as a research preview, an AI application security agent designed to detect and patch complex code vulnerabilities. The tool analyzes project context to reduce noise and increase confidence in vulnerability detection.

OpenAI released version 2.27.0 of its Python SDK on March 13, 2026, adding significant improvements to the Sora video generation API. The update introduces character API support, video extension and editing capabilities, and higher resolution export options.

GitHub has released the Copilot SDK, positioning executable agent workflows as the successor to prompt-based AI interactions. The SDK enables developers to integrate agentic AI capabilities directly into applications rather than relying on text-based prompt-response patterns.

GitHub is positioning AI interaction as a shift from prompt-response text interfaces to programmable execution models. The company announced a GitHub Copilot SDK that enables agentic workflows to run directly within applications, marking a transition toward AI systems that take concrete actions rather than generate text responses.

Anthropic has launched Code Review, a multi-agent system within Claude Code that automatically analyzes AI-generated code and flags logic errors. The tool addresses enterprise concerns about managing the increasing volume of code produced by AI systems.

Anthropic has added scheduled task functionality to Claude Code Desktop, allowing users to set up recurring automation that runs in the background. The feature enables Claude to perform routine developer operations like checking error logs and creating pull requests for fixable bugs at specified intervals.

OpenAI's GPT-5.4, an agentic coding model, is now generally available in GitHub Copilot. The model was tested on real-world software development scenarios and demonstrated improved coding capabilities.

OpenAI has released its Codex AI coding tool on Windows following rapid adoption on macOS. The app achieved over 1 million downloads in its first week on Mac and now serves 1.6 million weekly active users across platforms.

OpenAI is building an internal alternative to GitHub, Microsoft's dominant code collaboration platform, according to The Information. The move marks OpenAI's entry into developer tools and could create tension with its largest investor, Microsoft.

Anthropic has launched Voice Mode for Claude Code, allowing developers to interact with the coding assistant using voice commands. The feature expands Claude Code's capabilities beyond text-based interaction.

GitHub has published a hands-on guide demonstrating how developers can use GitHub Copilot CLI to move from initial intent through to creating reviewable pull requests. The guide shows how CLI-based development naturally integrates with IDE workflows and GitHub's collaborative tools.

Anthropic has expanded Claude Code accessibility to smartphones, tablets, and web browsers, allowing users to resume locally-running programming sessions across devices. The research preview feature enables seamless session continuity without requiring users to restart their development environment.

OpenAI released Python SDK version 2.23.0 on February 24, 2026, adding support for two new model options in realtime API calls: gpt-realtime-1.5 and gpt-audio-1.5. The minor update primarily focuses on expanding model availability for real-time applications.

Anthropic is rolling out new desktop features for Claude Code that automate additional steps in the development workflow. The update extends Claude Code's capabilities beyond the web interface to provide deeper integration with local development environments.
