This week's ChatGPT feature drop - Aug 7:

1/ Rich formatting in our web composer – When you paste in emails or documents, our composer will retain the formatting; copying and pasting is so common, we should have done this a while ago!

2/ Updated model for paid users – GPT 5.6 Sol is more consistent across quick chats and deeper reasoning. You'll now get a slider that lets you choose how much thought ChatGPT puts into a response. The haptics (vibrations) on mobile slider are fun!

3/ Unlimited text messages - Free users will get GPT 5.6 Luna with unlimited text messages. More intelligence for all. Rolling out soon.

4/ Fast Android Camera – We've made it a lot faster on Android to tap "camera" in ChatGPT to take a new photo and ask a question.

5/ Voice x Files - You can now upload files and ask questions in our new ChatGPT voice experience powered by GPT-Live.

Team demos were awesome this week. So much in the queue that the next few months are going to be good. Let us know what you're hoping for in the comments!

OpenAI is working hard to empower everyone with intelligence that works for them, in the form of great products which get simpler to use over time.

We're bringing unlimited text chats with Luna, a quite capable model, to free users.

We've also released an updated version of Sol which works for both quick chats and for deep reasoning — historically these have been different models. This unification is a very significant step towards making ChatGPT simpler and more intuitive.

OpenAI@OpenAI

We’re making better intelligence easier to access in ChatGPT for everyone:

- GPT-5.6 Sol now powers both Instant and deep reasoning for Plus & Pro users, delivering more factual, focused responses.

- Free & Go users get unlimited text chats with GPT-5.6 Luna starting tomorrow.

codex for customer feedback -> roadmap

Kappaemme@Kappaemme1926

CODEX SKILL THAT TURNS  CUSTOMER FEEDBACK INTO A ROADMAP!

Most feedback analysis stops at positive or negative.

I made a Codex skill that turns support tickets, interviews, surveys, reviews, sales calls, and churn notes into evidence-backed product priorities and credible customer proof.

Give it your feedback files and Codex maps recurring pains, ranks what to build next, and links every recommendation back to exact evidence IDs.

It keeps four things separate:

-what customers said
-the underlying problem
-what to validate or build next
-what you can honestly claim

-> feedback clustering with source traceability
-> product opportunity scoring
-> Now / Next / Later roadmap
-> customer proof + case-study candidates
-> objections, churn risks, and unsupported claims
-> searchable Startup Customer Evidence Map
-> privacy-first quote and consent handling
-> one-command install

What would you analyze first: support tickets, interviews, or churn notes?

Install: npx --yes startup-feedback-engine@latest
100% open source.

ChatGPT Voice for spending more time working from where you want:

Alex Finn@AlexFinn

ChatGPT Voice has 100% transformed how I work

Instead of spending 12+ hours a day at my desk, I now spend at most 2

The rest is outside in nature. Picture below is me hiking this morning, getting WAY more done then I ever have at my desk

You need to be using it right tho

Here are my best tips for getting the most out of Voice:

1. Use it to delegate, not actually do the work. Every command you give to your Voice agent, ask it to spin up a new thread and have another agent do the work. Voice is powered by a lower intelligence model. By delegating tasks, it gives the task to 5.6 Sol and allows your Voice agent to free up time to keep working with you

2. Frequently ask for status updates on all the work it delegates. I have found a higher silent failure rate than I'd like with delegate agents. By forcing your Voice/chief of staff agent to constantly check in on delegate agents, you can assure they are on top of their work

3. 'Spruce' is the best voice. Most pleasant to talk to

4. When on the go, frequently ask your Voice agent to create HTML sites for research/tasks it does. This way when you get back to your computer you have well designed HTML sites explaining work your agent got done. 

5. My favorite new routine is waking up at 6:00am, chugging water, putting on my weighted vest, grabbing my phone and airpods, getting outside, booting up the Voice Agent, then brain dumping everything on my mind about what I need to get done that day. The Voice agent then proceeds to spin up 10-15 new threads/agents to start tackling all of that work. By the time the clock hits 7:00am, I already have more work done than I was getting done in a full 8 hour work day before AI. Steal this routine

I'm probably the biggest power user of ChatGPT Voice outside of OpenAI employees. Truly blown away by this tech

If you take these tips and get the most out of Voice, I promise your productivity will 100x

GPT-5.6 Sol for improving production serving efficiency. One of the ways we're able to get such great price-performance:

OpenAI@OpenAI

After deployment, we applied GPT-5.6 Sol to advance the frontier of efficiency by making itself more efficient to run. 

The results:
- 20% lower serving costs from production GPU kernel improvements.
- 15%+ better token-generation efficiency from improved speculative decoding.
