OpenAI releases its answer to Claude Code, first AI model with “high capability” risk for cybersecurity

AI agents that can write code have quickly become one of the most profitable, and competitive, applications coming from the current crop of AI startups.

Anthropic’s Claude Code is enjoying a moment of popularity among software engineers, and it’s shoring up the startup’s revenue projections as it aims for an IPO this year. Claude Code’s launch, along with Anthropic’s release of Claude Cowork, which is aimed at nontechnical users, has been a key force behind software stocks’ massive recent underperformance.

Today OpenAI released its latest salvo in the AI code war: GPT-5.3-Codex, an “agentic coding” model that takes its name from OpenAI’s Codex coding app.

OpenAI says that GPT-5.3-Codex is the first model that was “instrumental in creating itself.”

According to the announcement, the new model can be used to build complex websites, interactive games, and achieved a new industry-wide high score on the widely used SWE-Bench Pro software development benchmark test.

But the model is also the first that OpenAI has released that comes with a “high capability” risk for cybersecurity, meaning the company’s evaluations showed that the tool had the potential to be used for sophisticated cyberattacks, though OpenAI says it has added mitigations to prevent such misuse.

Tesla’s made-in-China vehicle sales jumped 36% in April

Tesla’s sales of made-in-China vehicles — sold across China, Europe, and other international markets — rose 36% year over year to 79,478 units in April. The increase marks the sixth straight month of annual growth in sales of vehicles made in the world’s largest manufacturing economy, suggesting the EV maker’s overseas business may be stabilizing after a difficult stretch.

That said, China wholesale deliveries fell from March, even as overall new energy vehicle sales rose 7% during the period.

Later this month, the China Passenger Car Association will report China-only sales, offering a clearer picture of performance in Tesla’s second-largest market.

Anthropic’s scramble for compute now includes rival xAI

Another day, another major partnership with an AI rival. This time, Anthropic signed a deal with SpaceX’s xAI to access compute from its Colossus 1 data center to help it improve capacity for its Claude Pro and Claude Max subscribers. Just yesterday, The Information reported that Anthropic planned to spend $200 billion on Google Cloud services over the next five years. As Sherwood News’ Luke Kawa wrote:

“Anthropic has been a victim of its own success: the popularity of Claude Code and Cowork have revealed compute constraints and left users frustrated by caps. In response, the Claude developer has embarked upon a mad scramble for compute, striking or expanding deals with CoreWeave, Amazon, Google, and Broadcom.”

Now, it’s adding xAI to the list — even as the Elon Musk company builds a competing model.

In less terrestrial news, xAI said that as part of the agreement, Anthropic “expressed interest in partnering to develop multiple gigawatts of orbital AI compute capacity.”

SpaceX and Tesla’s Terafab could cost $119 billion — far more than expected

The initial phase of SpaceX and Tesla’s joint chip production effort, called Terafab, could cost $55 billion, with additional phases adding up to $119 billion in capital investment, Reuters reports, citing a notice posted on a Texas county website. Ultimately the goal of Terafab is to build enough in-house AI chip capacity to supply both companies.

The price tag is also higher than expected. Morgan Stanley had previously estimated Terafab would cost $34 billion to $45 billion.

Fortunately for Tesla, whose capex is expected to skyrocket this year, much of the early spending will sit on SpaceX’s balance sheet.

Here’s Musk on the last earnings call:

“SpaceX is going to take care of like the initial phase of the scaled up Terafab... Any kind of intercompany thing has to be approved by both the SpaceX and Tesla board of directors. It’s got to go through a conflict resolution. It’s going to have, unfortunately, a lot of complexity because we’ve got to make sure Tesla shareholders are served and SpaceX shareholders are served, and strike the right balance there.”

Apple to let users choose between Anthropic, Google, and OpenAI models

Apple has been inching toward letting outside AI power its devices — and now it’s going further.

The company plans to let users choose between rival AI models across iOS 27, due this fall, expanding beyond ChatGPT to include players like Google and Anthropic, Bloomberg reports. The difference this time: deeper integration, with outside models powering features like Siri, writing tools, and image generation across the system.

Currently, Apple’s voice assistant, Siri, gives users the ability to query ChatGPT, but doing so requires a clunky extra step and usage has been poor. Meanwhile, Apple’s own AI tools have fallen short. (Apple has decided to use Google’s Gemini to power Siri in the future.) It’s not clear users care which AI is under the hood — as long as it works.
