Frequently asked questions

DeepSeek FAQs

How much does DeepSeek cost?

DeepSeek V3 costs $0.27/1M input and $1.10/1M output tokens — roughly 10× cheaper than GPT-4o for comparable capability. DeepSeek R1 is $0.55/1M input and $2.19/1M output.

Is DeepSeek open-weight?

Yes. Both DeepSeek V3 and DeepSeek R1 are open-weight models available on Hugging Face. You can self-host them on your own GPU infrastructure, though they require significant compute (671B parameters for R1).

How does DeepSeek R1 compare to OpenAI o1?

DeepSeek R1 scores comparably to OpenAI o1 on math and coding benchmarks at a fraction of the cost. R1 is open-weight and can be self-hosted, while o1 is proprietary. R1 is available via multiple inference providers including Fireworks AI and Together AI.

Lepton AI FAQs

What models does Lepton AI support?

Lepton AI hosts Llama 3.3 70B and other popular open-weight models. Their catalog is focused on the most widely-used models rather than breadth.

How does Lepton AI pricing compare to competitors?

Lepton AI offers competitive pricing on Llama 3.3 70B, comparable to Together AI and Fireworks AI. Check their pricing page for current rates.

Is Lepton AI good for production workloads?

Lepton AI is suitable for production workloads with auto-scaling and serverless infrastructure. For very high-volume or latency-critical production use cases, Groq or Cerebras may offer better performance.

Provider category context

DeepSeek is a frontier lab, founded in 2023. Lepton AI is a inference api, founded in 2023. DeepSeek as a frontier lab trains and serves its own proprietary models. Lepton AI as an inference API provider hosts open-weight models — typically offering lower prices for equivalent capability tiers but without access to proprietary frontier models.

How to choose between them

Choose DeepSeek if you need deepseek v3 matches gpt-4 class at $0.27/1m input — 10× cheaper. Choose Lepton AI if you need clean developer experience with minimal setup. For high-volume production workloads, run a cost comparison using the token pricing table above with your actual prompt/completion token ratio — the cheapest provider depends heavily on your input-to-output token ratio.
