GPT 5.5 + Codex Just Became the Best Model Ever
Testing GPT 5.5 “Spud” in Codex: Faster Agents, Browser/Computer Use, and Knowledge Work
This video covers OpenAI’s new GPT 5.5 model, code-named Spud, and why it is stronger for real work, long tasks, tool use, and finishing complex goals.
GPT 5.5 pricing and why model cost should be judged by task quality, token efficiency, retries, and completion time, not only price per million tokens.
How GPT 5.5 compares to GPT 5.4, especially better intent understanding, stronger knowledge work, improved physics, and better browser/computer control.
Codex as the best and cheapest place to try GPT 5.5, including model effort settings and usage on the $20 plan.
