OPENAI 🔥: Key insights from upcoming DevDay sessions.
* This agenda is not public yet
First, OpenAI will build Platform capabilities inside Codex, enabling users to develop plugins, agents, and apps right from a dedicated DevDay page, which is quite cool!
Highlights from the agenda 👀
> Claw Labs "Join Peter Steinberger for a look at how agents can change the way open-source teams build."
> 🔥 Codex Game Studio "What makes a game easy for humans but hard for AI? Build one and put Codex to the test."
> 🔥 What Will You Build With Coding Agents That Don’t Quit? What engineering work deserves your time and tokens? Learn from a Codex run that spent more than 1,000 hours keeping builds and tests passing in a large shared codebase. See how this internal OpenAI agent had goals, subagents, and persistent plans that helped it investigate failures and coordinate fixes.
> Codex Has Left The Laptop "As we move from delegating individual tasks to letting Codex tackle entire problems and goals on its own, it’s possible to harness the power of Codex wherever and however you work. "
> From Single Player to Multiplayer with Codex "Follow a 2am outage from the first Slack messages to a reviewed fix and an update for the team."
> What Comes After Loops?: Deep Dive Into Agentic Architecture "As models become more capable, agent architectures are changing. We'll trace the evolution from simple loops to collaborating agents, examine the design choices and model advancements behind that shift, and take a deep dive into what comes next."

OPENAI 🔥: OpenAI won’t release GPT-6.1 Astra due to safety concerns, according to WSJ.
> “The company had planned to launch the model, known as GPT-6.1 Astra, in the coming days or weeks, aiming for an October debut. The model was more capable than the company’s previous models in completing challenging tasks from end-to-end without human assistance, as well as writing.”
> “While GPT-6.1 Astra improved in areas such as “model laziness,” Jain said it didn’t quite meet OpenAI’s bar for safety and alignment, so the company decided not to launch the model publicly.”
OpenAI is clearly aiming high on long running tasks performance. “Loop” capabilities will also need new benchmarks and measures.
Back to patience cave 💀

OpenAI is working on "Spaces" 👀
A new announcement introducing "Spaces" was added recently.
Spaces could be collaborative environments where users and agents work together on generated artifacts (speculation).
Some DevDay sessions mention a "Codex run that spent more than 1,000 hours" and the "Multiplayer Codex" topic, which might be closely connected (speculation).

OPENAI 🔥: “Dots” will be the name of upcoming AI agents from OpenAI, according to new strings that have surfaced in recent builds.
……
Does this mean that “o” is something else on top of it?
"Dots, your remarkably capable agents." You can text it, call it, Slack it, and email it, and it can buy things for you with your approval.”
“Each dot gets its own 3D character you design.”

“We leave in the era of underpriced compute”,
why? Because once we have accessible blueprints to convert tokens into money, prices will adjust as a global compute shortage hits.
why? Because businesses will start pouring huge money into these funnels, able to generate x5-x100 revenue from token costs.
ICYMI 👀: OpenAI is resuming $200 Pro subscriptions but cutting its usage capacity by half.
Yet, there won’t be 5h limits, and the expectation is to get even more efficient models soon.
Yet, factoring in that there is a new $500 plan potentially coming soon, this doesn’t look very good for any ChatGPT Pro user.
