OpenAI expanded its Agents SDK by separating the agent harness from compute/storage, enabling long-running, durable agents with features like file/computer use, skills, memory, and compaction. The harness is now open-source and supports execution via partner sandboxes, fostering a new ecosystem with integrations from Cloudflare, Modal, Vercel, and others. Cloudflare launched Project Think, a next-gen Agents SDK with durable execution and sandboxed code, alongside Agent Lee, a prompt-driven UI agent using sandboxed TypeScript, and introduced real-time voice pipelines and browser automation tools.

Hermes Agent focuses on persistent skill formation by learning from completed workflows, positioning itself as a professional agent distinct from GUI-first assistants like OpenClaw. "Hermes autonomously backfills tracking data, updates cron jobs, and saves workflows as reusable skills," highlighting its advanced workflow management capabilities.
