Summary
GPT 5.5 is here, and the first reactions are split between benchmark dominance, coding debates, Anthropic comparisons, and questions about whether the upgrade will feel dramatic to everyday users. NLW breaks down the launch, the “real work” positioning, the Mythos backdrop, and what changed in OpenAI’s communication strategy, then shares what he learned testing GPT 5.5 across writing, coding, strategy, design, spreadsheets, and data analysis.

| 0:00.0 | GpT 5.5, aka Spud, is here, but does it live up to expectations? |
| 0:05.5 | This is one of the most hyped models we've had in a very long time, |
| 0:08.9 | and we are going to go through all of the first reactions, the benchmarks, |
| 0:12.3 | and of course, about a dozen of my own tests. |

| 1:11.0 | right now, you can claim your username and be first in line to hear about another free program |
| 1:14.8 | we have launching tomorrow on an operator's bonus episode. |
| 1:18.8 | Well, friends, it is here. Ever since back in December, when OpenAI declared a code red, |
| 1:25.9 | we knew that they were deep in the lab cooking something good, |
| 1:29.0 | or at least we hoped it would be good. |
| 1:31.3 | Certainly the last few months have seen the company regain its verve, |
| 1:34.8 | particularly around Codex, which has grown from just a couple hundred thousand users at the beginning of the year to over 4 million now. |
| 1:40.7 | We've heard about the elimination of side quests, TBPN acquisition notwithstanding, |
| 1:45.4 | and overall that focus has seemed to reshape the company. And ultimately, leaked memos and grand |
| 1:50.6 | statements about focus don't matter a fig if it doesn't produce results. Now, honestly, for OpenAI, |
