Long-horizon agentic coding: Gemini 3 and Codex-Max as inflection point¶
Insight: Gemini 3 and GPT-5.1-Codex-Max mark the same inflection point: agents can now reason through long-horizon software tasks, navigate multi-step decisions, refactor at the project level, and operate across extended sessions without collapsing under context drift. The surface area of what an AI agent can meaningfully carry in a build has expanded significantly.
Detail: Gemini 3 improvements: stronger agentic coding (planning, tool use, end-to-end execution), zero-shot full-app generation, and Google Antigravity (agent-first development with direct access to editor, terminal, browser). Both releases converge on the same underlying capability — deeper reasoning, more stable planning, richer multimodal understanding.
