What is DeepSeek V3?
DeepSeek V3 is the flagship model from Chinese AI lab DeepSeek — a 671-billion-parameter mixture-of-experts model that competes with frontier closed models on benchmarks at a fraction of the price. Open weights under a permissive license. Strongly priced API access from DeepSeek directly.
How tokens are counted here
DeepSeek uses a BPE tokenizer derived from the LLaMA family with extensions. We approximate in your browser, accurate to ~±3% for typical English text. Marked ≈±3%.
For exact counts, use DeepSeek's official tokenizer via Hugging Face: AutoTokenizer.from_pretrained("deepseek-ai/DeepSeek-V3").
Why DeepSeek matters
The price-to-capability ratio is the most aggressive in the industry as of 2026:
- Input: $0.27 per million (DeepSeek API direct)
- Output: $1.10 per million
- Capability: comparable to GPT-4o on most benchmarks
That's roughly 9× cheaper than GPT-4o on input, 9× cheaper on output, with similar quality on most tasks.
When to use DeepSeek
- Cost-sensitive frontier-tier workloads — coding assistants, RAG over large corpora, batch reasoning jobs.
- Open-weights workloads where you want to fine-tune or self-host eventually but use API for development.
- Workloads with no concerns about Chinese-vendor data flow. Some enterprise compliance regimes restrict this; check before committing.
When not to use it:
- Production workloads with regulatory concerns about cross-border data transfer to China.
- Workloads requiring the most reliable function-calling — OpenAI's structured outputs are still the gold standard.
- Real-time chat where DeepSeek's higher latency vs Anthropic/OpenAI matters.
Pricing notes
Pricing is from DeepSeek's official API. Self-hosting (via Together, Replicate, etc.) costs more — DeepSeek subsidizes API access aggressively. Verify on api-docs.deepseek.com.
DeepSeek also offers prompt caching at substantial discount (cached input tokens at ~10% of standard rate). Not reflected in this calculator.
Common questions
Is using DeepSeek's API safe for production data?
Read DeepSeek's data-handling policy and your own compliance requirements. The API does process your prompts in China-based infrastructure. For sensitive data, self-host the open weights via Together.ai or similar.
How does DeepSeek V3 compare to Claude Sonnet on coding?
DeepSeek tends to win on raw code generation benchmarks. Claude Sonnet tends to win on understanding complex existing codebases and producing edits that match local conventions. Try both with your prompts.
What's the context window?
128k tokens. Comparable to GPT-4o, Llama 3.1, and Claude Haiku. Below Gemini 2.5 (1M+) and Claude Sonnet/Opus (200k).
