Product
- Claude Opus 4.6 launches as Anthropic’s new flagship model, significantly boosting coding and agentic workflow performance
- GitHub Copilot rolls out GPT‑5.3‑Codex plus Claude Opus 4.6 across VS Code, web, mobile, CLI and the Copilot coding agent
- ChatGPT ships deep‑research upgrades (targeted sources, editable plans, progress tracking) and a GPT‑5.2 Instant style update for clearer advice
- Devin adds Scheduled Devins and Devin Review draft‑PR support, moving closer to “always‑on” agentic dev workflows
- Cursor increases agent usage limits, creates separate Auto/Composer vs API pools, and improves large‑repo indexing for faster semantic search
UX/UI
- ChatGPT deep research gets a redesigned sidebar entry point, fullscreen report view, and mid‑run plan editing for more controllable research sessions
- GitHub improves the PR “Files changed” view with CODEOWNERS validation, layout tweaks, and performance gains for large reviews
- Cursor introduces a new usage‑visibility page so users can track separate Auto/Composer and API usage pools directly in the editor
- Devin’s new Schedules page makes it easier to configure recurring agent runs with prompts and playbooks from a dedicated UI
- ChatGPT Voice update improves how the assistant follows user instructions and uses tools like web search, especially for free‑tier and fallback Voice
Engineering
- GitHub Copilot’s new GPT‑5.3‑Codex model delivers stronger reasoning for long agentic workflows and up to 25% faster performance versus GPT‑5.2‑Codex
- Claude Opus 4.6 is positioned as a premium model for large codebases and complex agent chains, with hybrid “instant vs extended” reasoning controls
- Cursor shares results from week‑long “very long‑running” coding agents, peaking at over 1,000 commits per hour across hundreds of agents in research preview
- Cognition rebuilds Devin’s Agent Preview on Claude Sonnet 4.5, claiming 2× speed and 12% better scores on internal junior‑developer evals
- Claude Code’s February changelog highlights new task‑dependency management, background agents, plugin system, and tighter permission enforcement for agent workflows
DevOps
- Devin’s v3 API adds enterprise IP access‑list endpoints for centrally managing which networks can hit Devin in production
- Northflank publishes a practical guide to sandboxing AI agents (microVMs, gVisor, strict isolation) to contain code execution and tool abuse
- GitHub Actions’ early‑February updates improve runner enforcement, ship new Actions features, and open‑source the Dependabot Proxy for supply‑chain security
- Devin’s Scheduled Devins feature effectively turns agents into cron‑like jobs, integrating recurring automation into CI/CD‑style workflows
- OpenCode’s CLI docs, updated through Feb 13, emphasize deeper GitHub and MCP integration, including GitHub mock events for running agents in CI
