Brief
GPT 5.5 produced 9h 00m 49s of uninterrupted, agent-driven work that resulted in MLX TypeScript support for Flux2, Z Turbo, and Qwen image generation. @nummanali says an agentic setup (AGENTS/CONTINUITY/MEMORY/PLAN files and .agents/skills), plus Codex CLI compaction strategies and five engineering principles, enabled long-running coherence and self-improvement.
Why it matters
@nummanali reports GPT 5.5 performed 9h 00m 49s of coherent work building an ML library and produced complete MLX TypeScript support for Flux2, Z Turbo, and Qwen image generation (post published 2026-05-01).
Key details
- They ran the model with an agentic stack (AGENTS.md, CONTINUITY.md, MEMORY.md, PLAN.md, and .agents/skills), enabling the model to steer work, pick tranches from a plan, dynamically update task lists, and self-improve skills.
- They credit Codex CLI/app compaction strategies for maintaining coherence across many (if not hundreds of) compactions, call GPT 5.5 the biggest release since The Great Awakening (Dec 2025), and recommend asking Codex to optimize your repo for agentic engineering.
