Surprise Elon Anthropic Team Up Reshapes the AI Race

**Nathaniel Whittemore** (0:00)
Today on The AI Daily Brief, a surprise team up between Elon and Anthropic could totally reshape the AI race. And before that, in the headlines, sort of, it's kind of all one big episode today. Everything that was announced at the Code with Claude Anthropic event yesterday. The AI Daily Brief is a daily podcast and video about the most important news and discussions in AI.
All right, friends, quick announcements before we dive in. First of all, thank you to today's sponsors, KPMG, Granola, Section, and ZenCoder. To get an ad-free version of the show, go to patreon.com/aidailybrief, or you can subscribe on Apple Podcasts. If you want to learn more about sponsoring the show, send us a note at sponsors at aidailybrief.ai. And just a couple other action items. First, the April AI Usage Pulse Survey is live. If you want to see all the results from the previous months, go to pulse.aidailybrief.ai. There's a link to the survey from there as well. And then a quick mention of our latest AIDB training programs. The free Agent OS Self-Directed Program to Build an Agentic Operating System has tons of you building right now, and I'm really, really loving seeing all the things that you're doing. And then if you are a team that is looking for something similar but more hands-on, we've got the third cohort of Enterprise Claw registering. And if you need a little primer even from that, a new four-week executive sprint called AI Executive Catch-Up that'll take you from basic prompting all the way to being ready to build your first agents. As always, all the info for that can be found at aidailybrief.ai.
Now, with that out of the way, let's talk about yesterday's big news.
Yesterday was Anthropics Developer Day, and so I knew that today's episode was going to be all about whatever it was that they announced. Now, there were some really interesting things. And in many ways, I think you can view their conference as a really interesting indication of where companies are with agents, the problems they're trying to work on, and the significance of harnesses in the AI race. But when it comes to the AI race, everything that was announced at Dev Day was absolutely drowned out by the surprise announcement of an Elon Musk, SpaceX, and Anthropic team up. So what we're going to do today is we're not going to strictly divide this into headlines in main, but instead the practical tool and tech related announcements from Dev Day are effectively the headlines, while the Elon Anthro story is going to be the equivalent of the main. But let's talk about Dev Day because I don't want to undersell how interesting it was even though the other thing is dominating the conversation. Right from the beginning, you could tell where the emphasis was going to be in this event given that they called it Code with Claude. Now, at last year's event, Anthropic rolled out Sonnet 4 and Opus 4, which was their response to OpenAI's 3 This year, there was no big model release. We didn't get a public rollout for Mythos or even a hint of when and how that might happen. Nor did we get any hints about Opus 48 or 49 or anything in the line. Instead, the focus was squarely on agents and the applications built around Anthropic's models, which I think reflects how competition has changed in AI over the last six months. It would be insane to say that models don't matter at this point. Most high-value production use cases are, of course, using either Opus 47 or GPT-55, and the advances specifically of GPT-55 have helped OpenAI significantly reclaim some narrative space. And yet, if you had to put your finger on the important competition of 2026, it's been way more about Codex vs. Claude Code than it has been about Opus vs. GPT.
And I think what we're starting to see is the next evolution in the process. Increasingly, you see Claude Code evolving into an ecosystem of agent harnesses that are tuned for particular workflows. That process began with co-work but has been refined into even more specific workflows like Claude Design. And while OpenAI is taking a different approach with Codex, trying to centralize all the activity in that one app space, you are at least seeing little hints of this harness customization, for example, in the form of Codex's Quickstart profiles for various different professions. But when it comes to what was announced at Code with Claude this week, it reads like a map of the key challenges of agents. We have features focused on memory, features focused on quality review, and even some hints towards a future question of continual learning. The centrally releases were all around Claude-managed agents.
