**[Perplexity Enters AI Programming, Directly Competing with Cursor]** According to monitoring by Beating, AI search company Perplexity is internally developing an AI programming tool called Teammate, aiming to challenge Cursor, Claude Code, and OpenAI Codex. Teammate has been available for internal use by Perplexity engineers since May, focusing on longer-term software engineering tasks, including advancing projects, troubleshooting issues, monitoring services, and identifying vulnerabilities in internal systems. It features a model-agnostic design, not tied to a single underlying model, functioning more like an engineering project agent rather than a standard code completion tool. Perplexity CTO Denis Yarats has also recently been encouraging engineers internally to use AI for coding, stating that software engineers should "stop looking at code" and directly use AI by the end of the year or sooner.
