i love that the team does stuff like this
Codex is not like claude code.
if you know the limit is going to end, like last 10 to 8%, give an very long run task, and even after the limit got ever, it will continue to do the task until the task was completed.
Shout out to @OpenAI team.

So beyond happy to welcome Statsig and @vijayeraji to OpenAI! Vijaye is one of the best leaders I’ve had the chance of working with and I can’t believe I’m lucky enough to do it a second time.
.@Statsig is joining @OpenAI.
Over the past 4.5 years, we’ve built something special at Statsig: a platform that the world's best technology companies rely on to build fast and make smart decisions. We’re going to join forces with OpenAI to vastly expand our mission, while maintaining continuity for our current customers.
I’m super excited to join OpenAI as CTO of Applications, reporting to @fidjissimo .
Working with the incredible team at OpenAI to build AI-powered experiences at scale for people and businesses is a rare and meaningful opportunity. Doing that with the help of tools we built at Statsig makes it even more special.
Once the acquisition is finalized, Statsig employees will become OpenAI employees. The company will continue operating independently and serving our customers.

From countless meetings in Seattle and joining daily standups in their early days to today’s milestone, we’ve seen firsthand @statsig's discipline, creativity, and impact on many of the world’s leading product teams.
Thrilled for @vijayeraji & team as they help define the future of AI-native experimentation.

@statsig's co-founder @vijayeraji on the one skill founders ignore:
I wish I had spent more time with my sales and marketing friends at Facebook.
Never thought to drill down deeper - how are teams structured? Incentivized? Different types of marketing?
could have saved a lot of early failures

What happens with time savings thanks to AI tools? This is where things get really weird...
Laura Tacho (@rhein_wein) is the CTO at DX, and lives and breathes developer productivity, and rejects the hype that is all too common these days. We talk about how to separate signal from noise, and what data today tells us about AI tools and developer efficiency.

To put that in perspective: 18 million events per second.
Here’s how a startup built the infra to handle it — and the lessons from getting there.

What does it take to land a job as an AI Engineer—and thrive in the role?
@janvikalra_ works at OpenAI in this role: and she transitioned from software engineer to AI Engineer at her previous company, Coda. Before joining OpenAI, she interviewed with 46 different AI startups (!!) and so has an unusually broad and deep overview of how interviews work, how companies compare, and practical mental models to think about your career.

Two of my takeaways from talking with Janvi:
𝟭. 𝗧𝗲𝗮𝗰𝗵𝗶𝗻𝗴 𝘆𝗼𝘂𝗿𝘀𝗲𝗹𝗳 𝘁𝗵𝗲 𝗯𝗮𝘀𝗶𝗰𝘀 𝗶𝘀 𝘀𝘁𝗶𝗹𝗹 𝗮 𝗴𝗿𝗲𝗮𝘁 𝘄𝗮𝘆 𝘁𝗼 𝗴𝗲𝘁 𝗶𝗻𝘁𝗼 𝗔𝗜 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴. Janvi wanted to move onto Canva’s first AI Engineering team, but she was politely rejected at first. Instead of giving up: she started to teach herself how to build apps using LLMs. She went to hackathons, educated herself online, and built apps on the side.
A few months later, she was already one of the experts at work on how to work with LLMs. So the next time Canva’s AI team was expanding, the team was thrilled to have her on! My two cents: it’s much easier to transfer internally, so if you are hoping to get into AI, see if you can do something similar to what Janvi did.
𝟮. 𝗔𝗜 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 𝗶𝗻𝘁𝗲𝗿𝘃𝗶𝗲𝘄𝘀 𝗮𝗿𝗲 𝗮𝗹𝗹 𝗼𝘃𝗲𝗿 𝘁𝗵𝗲 𝗽𝗹𝗮𝗰𝗲. Janvi got a broad look at the AI Engineering job market, thanks to interviewing with 46 different companies (!) There doesn’t seem to be an “AI Engineer interview” format. Instead, interviews are a mix of:
• Leetcode-style algorithmic interviews
• System design interviews
• Project-based takehomes where you need to build an app
• Domain deepdives into LLM specifics
This means that the best way to prepare for these interviews is to prepare for software engineering interviews: build products using LLMs on the side, and familiarize yourself with common AI Engineering concepts (some covered here: newsletter.pragmaticengineer…)
