Pretty good year if you ask me. The team grew a ton, just sent the last offer of 2025. We released updates to Agents SDK and Sandbox SDK every few days on average, slowly stacking MCP updates, improving transports, and sandboxing with code interpreters, @opencode integrations, Git, streaming, and a lot more. We focused hard on the foundations for agents. Agents need computers, and building both is a journey. Building these blocks has been one of the most satisfying things I’ve worked on. Grateful every day for the people beside me: @threepointone @ghostwriternr @mattzcarey @caise_p Ready for 2026!
