deepseek-v3.1-terminus API — compare providers
The same model (deepseek-v3.1-terminus) is served by 3 providers; AtlasCloud is the cheapest at $1.25/1M blended — the priciest (Novita AI) costs 2% more. On quality, deepseek-v3.1-terminus scores 1415 on the LMArena (Chatbot Arena) — so the cheapest endpoint is also the best value per dollar here.
Quality and intelligence scores are attached to the model itself — identical whichever provider serves it. Verified 2026-09-04.
| Rank | Provider | Input /1M | Output /1M | Blended /1M | Value (Elo/$) |
|---|---|---|---|---|---|
| 1 | AtlasCloud | $0.3 | $0.95 | $1.25 ← cheapest | 1,132 ← best value |
| 2 | SiliconFlow | $0.27 | $1 | $1.27 | 1,114 |
| 3 | Novita AI | $0.27 | $1 | $1.27 | 1,114 |
Value = model Elo ÷ blended price per 1M tokens. Since the model's quality is identical across providers, the cheapest endpoint is also the best value per dollar.
Prices are per 1M tokens (USD). "Blended" = input + output, for coarse ranking. Same underlying model, 3 serving providers, 2% spread top to bottom. Context window: 163,840 tokens (65,536 max output) — see how it ranks in biggest context windows. See how this compares across the catalogue in same model, different price, or find the best quality per dollar in the value ranking.
Cost per 1,000 requests by workload
What each provider actually bills for a representative job, not just the sticker price.
| Provider | Chatbot 1000 in / 500 out | RAG / long context 8000 in / 500 out | Batch summarize 4000 in / 1000 out |
|---|---|---|---|
| AtlasCloud | $0.78 | $2.88 | $2.15 |
| SiliconFlow | $0.77 | $2.66 | $2.08 |
| Novita AI | $0.77 | $2.66 | $2.08 |

Self-host / quantized builds
Open weights under MIT — you can run deepseek-v3.1-terminus on your own hardware instead of paying per token. Even quantized to int4 it needs on the order of 402.6 GB of VRAM — quantization lowers the footprint but this model still needs a multi-GPU server, not consumer hardware. Formats: GGUF for llama.cpp / Ollama / LM Studio, AWQ and GPTQ for GPU serving, MLX for Apple silicon.
- GGUF builds llama.cpp · Ollama · LM Studio
- AWQ builds GPU serving (vLLM)
- GPTQ builds GPU serving
- MLX builds Apple silicon
- Ollama library one-command local run
Links search the live model hubs (Hugging Face, Ollama) so they track new builds as they appear — we don't host weights. Which formats exist depends on what the model owner and community have published.
