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 to call on NovAI (no credit charge; 10 calls/day on the free tier, 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 110+ Chinese frontier models, with five free models (10 calls/day on the free tier) 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

Which model per component

Flow component	Model	Cost
Router / classifier (high volume)	glm-4.7-flash	Free (10 calls/day)
RAG answer generation	glm-5.3-flash	$0.08 / $0.28 per 1M
Vision component	glm-4.6v-flash	Free (10 calls/day)
Agent reasoning / tools	deepseek-v4-pro / kimi-k2.7-code	see live leaderboard

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.
