Vercel Is Training AI on Your Code

Go ad-free!

If you work in fintech or finance, you already have too many tabs open and not enough time.

Fintech Takes is the free newsletter senior leaders actually read. Each week, I break down the trends, deals, and regulatory moves shaping the industry — and explain why they matter — in plain English.

No filler, no PR spin, and no “insights” you already saw on LinkedIn eight times this week. Just clear analysis and the occasional bad joke to make it go down easier.

Vercel updated its Terms of Service, and the big detail is in the defaults: free-tier users are now opted in to let Vercel use their code and agent chats to train AI models and share that data with third-party providers. Paid Pro users are opted out by default; Enterprise is excluded. The opt-out deadline is March 31. After that, opting out only prevents future use. If you're on the free tier, check Team Settings > Data Preferences now. Source

OpenAI signed an AWS deal to sell AI products to U.S. government agencies (source). They’re stepping onto Anthropic's home turf weeks after Anthropic was designated a supply chain risk for refusing to drop ethical restrictions. Microsoft is reportedly considering suing, arguing the deal violates its exclusive cloud agreement with OpenAI (source).

OpenAI is also acquiring Astral, the company behind uv, Ruff, and ty, which are three of the most widely used open-source Python tools. The Astral team will join Codex, and OpenAI says it'll keep the tools open source. That's the same promise they made about Promptfoo last week. Acquiring two open-source projects in the same month is a platform strategy. If you rely on uv or Ruff outside the OpenAI ecosystem, watch this closely. Source

Google SVP Nick Fox told Wired the company is "not ruling out" ads in Gemini. This is a shift from the "no plans" messaging at Davos in January. Fox called personalization the "holy grail" of Search and said Google's Personal Intelligence feature, which connects Gemini to your Gmail, Photos, and Calendar, could expand into broader Search. When asked about ad targeting with that data, he said, "TBD." Source
