Woofun AI reports that Perplexity is developing an internal AI programming tool named Teammate to compete with Cursor, Claude Code, and OpenAI Codex. Available to engineers since May, the model-agnostic agent handles long-cycle tasks like troubleshooting and vulnerability detection rather than simple code completion. CTO Denis Yarats advocates for engineers to "stop looking at code" by year-end, urging full reliance on AI for development.
