What base URL does Langflow need for NovAI?

https://aiapi-pro.com/v1 - set it on an OpenAI model component with your NovAI key; the model list is fetched from /v1/models.

Are there free models I can use in Langflow flows?

Yes: GLM-4.7-Flash, GLM-4.6V-Flash, GLM-4.1V-Thinking-Flash, CogView3-Flash, CogVideoX-Flash are free and unlimited on NovAI (no token cap, no card), so you can prototype entire agent flows for free. New accounts also get $2 credit for paid models.

Does NovAI add a markup on model prices?

No. Prices are the raw provider list rate with 0% platform fee (vs OpenRouter ~5.5%). Live per-model prices: /china-ai-leaderboard.json.

Langflow + Chinese AI Models (2026)

Updated 2026-10-10 · verified against the live model list

Langflow is a visual framework for building multi-agent and RAG flows as composable graphs. Point an OpenAI model component at NovAI and run your flows on 121 Chinese frontier models, with five free and unlimited so prototyping costs nothing.

Add the NovAI model component

In Langflow drag an OpenAI model component onto the canvas.
Set base_url to https://aiapi-pro.com/v1 and api_key to your NovAI key.
Set model to any Chinese model (e.g. glm-4.7-flash).
Wire it into your agent / RAG / chain flow.

# optional: run Langflow locally
pip install langflow
langflow run
# then set base_url=https://aiapi-pro.com/v1 on the OpenAI component

Troubleshooting

Component errors on run: confirm base_url ends with /v1; test curl https://aiapi-pro.com/v1/models.
401: key not active or credits exhausted — top-up from $5, or switch to a free model.
Local Langflow cannot reach NovAI: ensure outbound internet is available.
