Codex just got better for developers — Transcript

Full transcript

1. 0:00This is a big moment for Codex and I'm really
2. 0:02excited to show you what's new for developers.
3. 0:04Today, more than 6 million
4. 0:06of you use Codex every week.
5. 0:08Along the way, you've shared feedback,
6. 0:10shown us what you're building,
7. 0:11and you set an incredibly high bar.
8. 0:14You've asked Codex to ship ambitious projects
9. 0:16and help you stay organized beyond the code.
10. 0:19You've helped shape Codex at every step,
11. 0:21so before I show you anything, thank you.
12. 0:25Codex and ChatGPT are now coming together into one app.
13. 0:28For developers, it's the same Codex you know and love.
14. 0:31It now lives right here in ChatGPT with its own
15. 0:34dedicated space next to the new work agent.
16. 0:36We've been shipping new improvements every week,
17. 0:38more than 150 updates over the past
18. 0:40two months, and we're just getting started.
19. 0:43Let me show you a few of my favorites.
20. 0:45First, the model.
21. 0:47GPT-5.6 Sol is our new frontier model
22. 0:49and it's available to everyone.
23. 0:51It can work through hard problems for a very long time.
24. 0:54And you can also use the new
25. 0:55Ultra mode right here with GPT-5.6.
26. 0:59Combined with the Goal command,
27. 1:00you can give it the most challenging projects
28. 1:02you've been putting off, like this one.
29. 1:04With Ultra, Sol gets a much larger reasoning budget.
30. 1:07But be careful, Ultra will obviously
31. 1:09be using your token limits faster.
32. 1:11Now, as you can see here,
33. 1:13Codex will automatically split the work across
34. 1:15subagents without you needing to ask.
35. 1:17So I can follow any of them
36. 1:19individually or open this panel
37. 1:21and see the whole team working together.
38. 1:23One goal and all of this work now moving in parallel.
39. 1:26That's really awesome.
40. 1:28Sol is also outstanding at computer and browser use.
41. 1:31Of everything in this release,
42. 1:32this may be the feature I'm
43. 1:33the most excited for you to experience.
44. 1:35It's so much faster with GPT-5.6.
45. 1:38Say I'm working on this iPhone app, for instance.
46. 1:40I can simply take an appshot
47. 1:42of the Simulator by pressing Cmd-Cmd on Mac,
48. 1:44just like that, and say, navigate
49. 1:47through every screen and capture
50. 1:49the App Store screenshots in English and French.
51. 1:52You can think of an appshot as a smarter screenshot.
52. 1:55Codex gets both the screen and the app context.
53. 1:58With this,
54. 2:00Codex can use the Simulator itself.
55. 2:01Check this out.
56. 2:02This is not my cursor.
57. 2:04It's Codex clicking around and doing
58. 2:05all of this in the background where
59. 2:07I can continue to use my computer.
60. 2:09Isn't that amazing?
61. 2:10Switching gears, let's take a look at this very
62. 2:13simple paper plane game built with GPT-5.6.
63. 2:16I can open it directly in the in-app browser,
64. 2:19play with it, and see exactly what Codex created.
65. 2:22If I want to change something,
66. 2:24I can point and click here to annotate
67. 2:26the exact part I'm talking about.
68. 2:28Codex gets that visual context
69. 2:30to make the changes that I request.
70. 2:32We added a lot of features to the browser,
71. 2:34by the way, so you can now
72. 2:35work with applications that require login
73. 2:37as well, with support for passkeys.
74. 2:40And boom, here is the change.
75. 2:42I can also switch into the diff view.
76. 2:44I've always been able to inspect the diff
77. 2:46here, but now I can go further
78. 2:48and make precise edits directly inline.
79. 2:51So if I know exactly what I want,
80. 2:53I can change the line of code myself, just like that.
81. 2:56Or if I know the behavior I want,
82. 2:58but I'm not sure what the code change should be,
83. 3:01I can ask Codex to work from there.
84. 3:03Sometimes I want to work visually.
85. 3:05Sometimes I want to work directly into the code.
86. 3:08And it feels much closer
87. 3:09to actually pairing with the model.
88. 3:11Once I have something I'm happy with,
89. 3:13the next question is,
90. 3:14how do I put it on the internet?
91. 3:16That's where Sites comes in.
92. 3:18Last month, we introduced Sites for Enterprise,
93. 3:20so teams could create applications and share them internally.
94. 3:23Now, Sites is available to everyone,
95. 3:26and it works for any web
96. 3:27application that you build with Codex.
97. 3:29I can simply say,
98. 3:31publish this to Sites.
99. 3:34It has hosting, authentication,
100. 3:37a persistent database, and even file
101. 3:39storage, all built in.
102. 3:40So I can go from an idea
103. 3:42to a real full-stack application without really
104. 3:44thinking about infrastructure or hosting.
105. 3:47And there it is.
106. 3:49It's now deployed.
107. 3:51Zooming out a little bit, as you
108. 3:53delegate work to Codex across many projects,
109. 3:55we're continuing to make it easier
110. 3:57to see everything going on at once.
111. 3:59In fact, did you know that Codex can also
112. 4:01help you manage its own Codex tasks?
113. 4:03This is super useful when I
114. 4:05have several independent pieces of work
115. 4:07that I want to get organized and moving.
116. 4:09Check out this one.
117. 4:11Find five bugs from Linear,
118. 4:13create a separate task and isolated worktree for each one,
119. 4:17and pin the most critical ones.
120. 4:20And boom!
121. 4:21From this coordinating thread, I can see
122. 4:24now everything being kicked off and moving along.
123. 4:27So Codex is not only doing the work.
124. 4:29It's helping me keep all of it organized and connected.
125. 4:32The cool thing is,
126. 4:33these tasks can also reference one another.
127. 4:36Better yet, the work does not have to start in Codex.
128. 4:39If an idea starts in ChatGPT, or if I
129. 4:42explore it here with deep research, I
130. 4:45can now @mention that conversation
131. 4:48and bring all of the context straight
132. 4:50into Codex when I'm ready to build.
133. 4:52So no more copy-pasting.
134. 4:53And I'm not tied to my desk to manage Codex.
135. 4:57ChatGPT on mobile just got a big set of upgrades.
136. 5:00There are three things I wanted to try.
137. 5:02First, you can create, search,
138. 5:05open, manage tasks directly
139. 5:07from a conversation on your phone.
140. 5:10Second, reviewing changes is also much better.
141. 5:13I can filter between staged,
142. 5:16unstaged, branch, or compare
143. 5:18branches directly on the go.
144. 5:20And third, I can connect directly
145. 5:22to an SSH host, like a dev box,
146. 5:25and start new tasks from my phone.
147. 5:27There's so much more, but I love
148. 5:29that I can start something at my desk,
149. 5:31keep it moving from my phone,
150. 5:33and jump in whenever Codex needs me.
151. 5:35Isn't that great?
152. 5:36Back to desktop, we've also
153. 5:38made your day-to-day workflow smoother.
154. 5:41Codex now makes it easier to work with pull requests
155. 5:43without leaving the app.
156. 5:45It does this in context.
157. 5:47It knows which branch each task is working on.
158. 5:50So when that branch has an open PR,
159. 5:52the summary pane surfaces it automatically.
160. 5:54I can follow everything, address any issues,
161. 5:57and merge once everything looks good.
162. 6:00If a check fails, though, or a comment comes in,
163. 6:03I can ask Codex to fix it
164. 6:04right here with the full context.
165. 6:06The new Pull Requests tab
166. 6:08lets me explore every code change.
167. 6:10I can leave inline comments,
168. 6:13complete a full review.
169. 6:14I can also mark my own PRs as ready
170. 6:17and merge them.
171. 6:18All of this within Codex without having to go
172. 6:21to GitHub.com so I can stay in the flow.
173. 6:24This is only a small part of what we've shipped,
174. 6:27but the thing that matters most hasn't changed.
175. 6:29We're constantly improving Codex for developers,
176. 6:32and we're lucky to build it alongside you.
177. 6:34We hope you'll join us for OpenAI Build Week,
178. 6:37either online or in-person
179. 6:39at one of nearly 30 events around the world.
180. 6:42Okay, Codex, I'm done with the demo.
181. 6:45Can you get developers ready
182. 6:46for Build Week and wrap us up?
183. 6:49As always, keep giving us
184. 6:51your hardest bugs, your boldest ideas,
185. 6:54and the work that feels slightly impossible.
186. 6:57Thank you.
