How to build a Telegram agent in n8n

Summary

n8n's new September 2026 agent feature enables no-code AI agents with 10x more power than workflows—including parallel sub-agent spawning and web search—deployable to Telegram in minutes without coding. Builders can now create personal assistants with reasoning and tool access for just $5/month using cheaper open-source models via OpenRouter.

Key Takeaways

  1. Agents are now a separate entity from workflows in n8n, offering significantly more freedom and power through native parallel sub-agent spawning (up to 10 concurrent agents), a capability completely absent in previous workflow-based agents.
  2. The minimum viable agent requires only two components: a model selection and system instructions (the prompt). This low barrier to entry means functional agents are deployable in minutes without understanding advanced configurations.
  3. Cost optimization strategy: Use OpenRouter with budget-constrained open-source models like MuseSpark 1.3 ($5/month limit) instead of premium APIs, achieving 'Opus level intelligence for pennies on the dollar' with contributor pricing if data sharing is acceptable.
  4. Advanced reasoning and web search capabilities are toggled via settings tabs—simply enabling these features gives agents LLM thinking time and internet access without requiring workflow logic or custom code configuration.
  5. Telegram integration uses n8n's existing credential system—once OpenRouter credentials are connected, adding Telegram as a channel is a single-click operation, enabling multi-platform deployment of the same agent logic.

In this video, I'm building a powerful, always-on AI agent in Telegram with n8n. There isn't any code involved, and we actually aren't even using workflows. We're using the new agent feature in n8n that came out in September 2026. For this personal agent, I want it to be able to answer questions about me, do research for me, log my expenses, manage my to-do list. But to be honest, the capabilities of my agent doesn't matter that much. By the end of this video, you'll be able to make an agent to do pretty much whatever you want. So honestly, let's just dive right into it and you will see what I mean. It is super easy to set up. What do you think? Okay. Okay, now we'll get into it. And from the personal tab in here, or really any project that you're in, you'll now see this new agents tab. In…
