Here's the cold truth: if you're building anything with LLMs right now, you're probably overpaying by 10-40x.
I was spending $1,200/month on GPT-4o for my side project. A friend showed me his DeepSeek V4 Flash bill: $31. Same workload. Same quality.
The fix? Change one line of code.
# Before
client = OpenAI(api_key="sk-...")
# After
client = OpenAI(
api_key="sk-...",
base_url="https://dubhehub.com/v1" # ← this line
)
That's it. Same SDK. Same parameters. Same response format. Just a different endpoint.
The math that made me switch
| Model | Input (per 1M) | Output (per 1M) | Cost vs GPT-4o |
|---|---|---|---|
| GPT-4o | $2.50 | $10.00 | — |
| dubhe-fast (DeepSeek V4) | $0.30 | $0.60 | ~15x cheaper |
| dubhe-code (GLM-4.7) | $0.80 | $3.00 | ~3.5x cheaper |
| dubhe-reasoner (DeepSeek V4 Pro) | $6.00 | $18.00 | ~1.6x cheaper |
| dubhe-vision (multimodal) | $5.00 | $15.00 | — |
What actually works
I've been running on this for a month. Here's what works:
Chat & streaming — identical. SSE, function calling, JSON mode, all work the same way.
Multi-model routing — the biggest hidden win. I use dubhe-fast for 80% of my traffic (chat, summarization) and switch to dubhe-code for code review. Total cost: ~$40/month instead of $1,200.
Vision — works with image URLs and base64. Same format as OpenAI.
What doesn't
Fine-tuning, Assistants API, and TTS aren't available yet. If you need those, keep an OpenAI key handy. For the other 95% of use cases, you won't notice the difference.
The real reason I'm not going back
My app does ~200K requests/month. With GPT-4o: $1,200. With multi-model routing: $33.42.
The money I save in a month pays for my whole cloud infrastructure.
You can start with 100K free tokens — no credit card, no commitment. Test it with your actual workload. If the quality isn't there, you've lost nothing but 10 minutes.
