Power n8n workflows with
the best open-source models
Use Kyma as the LLM behind your n8n OpenAI, AI Agent, and Basic LLM Chain nodes. OpenAI-compatible, auto-failover, pay per use. No OpenAI key needed.
Best Open Models
Qwen 3.6 Plus for quality, Gemma 4 31B for cheap high-volume runs, Kimi K2.6 for agentic tool use: pick per workflow with one key.
Auto-Failover
For eligible failures, Kyma API tries another compatible route when available. Requests can still fail.
OpenAI-Compatible
Drops straight into n8n's OpenAI credential. Just set the Base URL and paste your key: every OpenAI-style node uses Kyma.
