Mechanism◆Article
Cloud agents are only becoming mainstream now because coding models finally got good enough to run autonomously, agent infrastructure like MCP and skills matured, context windows grew large enough, and cloud providers built up enough GPU capacity.
Gergely Orosz hypothesizes that cloud agents are taking off now due to converging factors: sufficiently capable coding models, mature agent infrastructure (MCP/skills), bigger context windows, and abundant cloud GPU capacity. ✦ AI generated

Coding models got 'good enough'. Before Opus 4.5 / GPT-5.4, AI models could not really code autonomously, so running them for long tasks was pointless! Infra for AI coding agents has matured. Ways of giving more context to agents have improved: things like MCP and skills became mainstream and better understood.
