### 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.

## Setup guide

1. [Create account](https://kymaapi.com/signup) → 2. Create the credential below → 3. Drop it into any LLM node.

**n8n: OpenAI Credential**

```
1. In n8n, open Credentials → New → search "OpenAI"

2. Create an "OpenAI account" credential and set:
   API Key:    kyma-xxxxx  (get yours at kymaapi.com)
   Base URL:   https://kymaapi.com/v1

3. Save. This credential now points every OpenAI-style
   node at Kyma instead of OpenAI.

That's it: no OpenAI key required.
```

**Use it in a node**

```
Add an OpenAI, AI Agent, or Basic LLM Chain node and:

  Credential:  the Kyma "OpenAI account" you created
  Model:       qwen-3.6-plus

Note: the Model field is free-text. Type any Kyma model
id directly: e.g. qwen-3.6-plus, gemma-4-31b,
kimi-k2.6, or deepseek-v4-flash. No dropdown limit.
```

## Pro Tips

Pick the right model per node to balance output quality and cost for your workload.

1

Use `qwen-3.6-plus` as your default for reliable quality across most workflows

2

Use `gemma-4-31b` on high-volume automations that run thousands of times a day to cut cost

3

Use `kimi-k2.6` in AI Agent nodes that call tools for tool-use workflows
