Problem solver first, developer second. I simplify until the answer reveals itself.


GPT-5.5 just dropped TL;DR: This is another o1 / o3 moment - Shorter, more human, actual personality - Clearly pushing into personal agents (OpenClaw) - Higher info / Token density → Cheaper to reach GPT-5.4-level intelligence It codes different: - Less bloat - Cleaner, readable output Codex: - Frontier agentic coding - Backend > Claude Opus 4.6 - Give it specs and it will build it - Handles large codebases, long runs, visual iteration loops GPT-5.5 Pro: - Does 30-90 min runs cohesively like it’s nothing - Writes full docs, uses tools well - Can solve basically anything Tradeoffs: - Slower than Opus - More expensive per token - (but more efficient overall) GPT-5.5 is the new bar


GPT-5.5 delivers this step up in intelligence without compromising on speed. GPT-5.5 matches GPT-5.4 per-token latency in real-world serving, while performing better across nearly every evaluation we measured. It also uses significantly fewer tokens to complete the same Codex tasks, making it more efficient as well as more capable.
