Conclusion
- DeepSeek can still be a low-cost benchmark, but pricing, cache rules, and credits must be rechecked before production planning.
- Keep Qwen and GLM as China-friendly compatible alternatives when DeepSeek cost, quota, or latency changes.
- Compare retry-adjusted cost: accepted answer rate, fallback rate, latency, and error behavior matter.
- A gateway is useful when you need to switch providers quickly without changing app code.
What to do next
- Open the official DeepSeek pricing page and record input, output, cache-hit, cache-miss, off-peak, and console credit status.
- Run the same 20 production-like tasks on DeepSeek, Qwen, GLM, and one fast/free prototype route.
- Calculate cost per successful task after retries, validation failures, and fallback calls.
- Move baseURL, apiKey, model, timeout, and max tokens into config so provider changes are not code rewrites.
- Use OpenLLMAPI or middleware when you need route logs, budget caps, and automatic fallback across providers.
Recommended paths
| Provider | Free / credits | Best for |
|---|---|---|
| DeepSeek | Verify current official pricing | Low-cost reasoning baseline when price/credit is current |
| Qwen DashScope | Signup credits vary | China-friendly coding, Chinese, and long-context fallback |
| Zhipu GLM | Signup tokens vary | Domestic GLM fallback and Chinese app coverage |
| OpenRouter/Groq | Free routes vary | Fast prototype comparison and no-card testing |
| OpenLLMAPI | Trial varies | One compatible endpoint with fallback and spend logs |
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.
Production handoff
Make DeepSeek price changes non-breaking
Put DeepSeek, Qwen, GLM, and fast fallback routes behind one compatible endpoint with spend logs and budget caps.
FAQ
Is DeepSeek still the cheapest LLM API?
Sometimes, but only after checking current official pricing and your workload. Cache behavior, retries, and quality can change the real cost.
What is the best DeepSeek alternative?
Qwen is strong for China-friendly coding and bilingual apps; GLM is useful as domestic fallback; Groq/OpenRouter are quick for prototypes; a gateway helps when you need multiple routes.
Should I switch immediately when price changes?
No. Benchmark your own tasks first and switch only if cost per successful task, latency, or reliability is better.
How do I avoid future price-change surprises?
Keep provider config outside business logic, log cost by route, set budget alerts, and maintain at least one fallback provider.
