Conclusion
- Low-code workflows can hide runaway costs through loops, retries, and scheduled runs.
- Compatible API fields make provider switching easy, but model behavior still needs testing.
- DeepSeek is a cost benchmark; Qwen and GLM are practical China-friendly routes.
- A gateway is useful when many Dify/Flowise apps need shared keys, logs, fallback, and caps.
What to do next
- Inventory every Dify app or Flowise chain that calls an LLM, including loops and scheduled triggers.
- Configure baseURL, key, model, timeout, and max tokens explicitly for each compatible provider test.
- Run the same workflows through DeepSeek, Qwen, GLM, and one fallback route with real inputs.
- Track accepted output rate, invalid JSON/tool calls, latency, retries, route cost, and user/workspace owner.
- Use OpenLLMAPI when workflow teams need one endpoint with provider switching, route logs, and budget caps.
Recommended paths
| Provider | Free / credits | Best for |
|---|---|---|
| DeepSeek | Verify current pricing | Low-cost Dify/Flowise text, RAG, and agent tasks |
| Qwen DashScope | Signup credits vary | China-friendly bilingual workflows |
| Zhipu GLM | Signup tokens vary | Domestic compatible fallback |
| OpenRouter/Groq | Free routes vary | No-card workflow prototypes and fast tests |
| OpenLLMAPI | Trial varies | Shared endpoint, logs, fallback, and workflow budgets |
Global developer checklist
- Confirm whether signup, billing, and API keys work from your country before writing production code.
- Prefer OpenAI-compatible endpoints when you may need to switch models, regions, or providers later.
- Test free credits with a real smoke prompt and record latency, error shape, streaming behavior, and quota burn.
- Keep at least one fallback route for provider outages, model deprecations, and regional access changes.

Connect Dify, Flowise, and automation tools to a compatible endpoint with logs, fallback rules, budget caps, and provider switching.
FAQ
Can Dify use OpenAI-compatible APIs?
Yes in many deployments when provider settings allow a compatible endpoint, key, and model. Test streaming, tools, and response parsing.
Can Flowise use cheaper compatible APIs?
Often yes through OpenAI-compatible chat model settings or custom endpoints. Verify baseURL casing, auth headers, and model names.
Why not just choose the cheapest token price?
Workflows may retry, loop, or fail validation. Accepted-output cost and fallback rate are better buying metrics.
When should I use a gateway?
Use a gateway when several workflows need one key, centralized logs, spend caps, fallback, or provider switching without editing every flow.
