GPT 5.5 + Codex Just Became the Best Model Ever

Summary

GPT-5.5 costs 2x more than GPT-4 but delivers higher quality outputs with fewer tokens—making it potentially cheaper per task. The real evaluation framework isn't token pricing but total cost-per-task including quality, token efficiency, and completion time.

Key Takeaways

  1. Stop comparing AI models by per-token pricing. Instead, benchmark identical tasks across models measuring: output quality, tokens consumed, task duration, and total cost. A cheaper model (GPT-4 at $2.50/M tokens) becomes more expensive if it needs 3.5M tokens vs. GPT-5.5 using fewer.
  2. GPT-5.5 excels at understanding intent throughout long multi-hour agentic tasks. This makes prompt clarity and full instructions critical—longer tasks require more detailed prompts to maintain intent focus throughout execution.
  3. GPT-5.5 significantly outperforms GPT-4 for knowledge work: generating documents, spreadsheets, and slide presentations. This makes it valuable for traditional white-collar jobs, not just coding.
  4. Computer use and browser automation is the greatest competitive race between OpenAI and Anthropic. Models controlling browsers/computers create enterprise value and enable job automation at scale.
  5. Codex introduced a new 'knowledge work view' making AI agents accessible for marketing and business purposes, not just technical tasks. This expands AI agent adoption beyond engineering teams.

Transcript Excerpt

OpenAI just released a brand new model called GPT 5.5 code name Spud and this model is really good. So not only did OpenAI release this new model and make it available for anyone to try, OpenAI also released three new updates to Codeex which in my opinion is the best place to use AI agents that exists in the world today. So, in this video, I want to talk about how good is GPT 5.5, what can it do, what is it better at, what is the best and cheapest way to use it, what does GPT5 mean for Codeex, m...
