1. Vercel Open-Sources deepsec, an Agent-Driven Security Harness

Vercel. deepsec is a code-security tool that drives Claude and GPT models through a tailored investigation pipeline — static analysis, agent-led investigation, revalidation, enrichment, and export — to find vulnerabilities across large codebases. Vercel reports a roughly 10–20% false-positive rate based on internal use, and is open-sourcing the harness rather than shipping it as a paid product. The architecture (multi-stage agent loop with revalidation) is interesting on its own as a reference for anyone building agentic code-analysis tooling. Source

2. General Intelligence Runs an Agent Team of 8 Humans + 4,000 Preview Branches on Vercel

Vercel. A case study from Cofounder maker General Intelligence describes running ~100 parallel app versions across more than 4,000 preview branches to give every agent (engineering, marketing, SEO, finance, sales, support, ops) its own deploy. With an 8-person company, the firm leans on Vercel’s preview environment as the substrate for its multi-agent organization rather than treating preview deploys as a developer-side affordance. The piece is a useful look at what “agents-first infrastructure” can look like in practice. Source
