Summary
Anthropic shipped Opus 4.7 and OpenAI shipped a much more ambitious Codex app on the same day. NLW digs into what's actually new in each, why the emerging "monothread" pattern could be the biggest unlock for knowledge workers, and gives a slew of use cases worth trying this weekend.

| 0:37.7 | Now, today is probably my favorite type of show when we get a whole slew of new goodies |
| 0:43.7 | and get to dig in and see what they can do for us, how our capabilities have changed, |
| 0:48.5 | what new use cases become unlocked, and what the patterns are telling us about where the world |
| 0:52.8 | is going. |
| 0:54.0 | Now, yesterday, we got not one but two big releases, one model and one harness. |
| 0:59.2 | The model, disappointing to some, was not Mythos preview or anything related to it. |
| 1:04.1 | It was Opus 4.7. |

| 1:15.1 | Now, on the other side, from OpenAI, we got a new iteration of their Codex application. |

| 1:29.1 | So what we're going to do today is discuss all the new things in both of these releases, |
