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.

xAI FAQs

What is Grok and how much does it cost?

Grok is xAI's family of frontier LLMs. Grok 3 costs $3/1M input and $15/1M output tokens. Grok 3 Mini is a cheaper reasoning model at lower price points. Both support vision and function calling.

Does Grok have real-time web access?

Yes. Grok models can access real-time web content and X/Twitter data, making them uniquely suited for applications that need current information beyond a training cutoff.

How does Grok 3 compare to GPT-4o?

Grok 3 is competitive with GPT-4o on most benchmarks with strong vision capabilities. Its main differentiator is real-time web and X/Twitter data access. Pricing is similar to GPT-4o.
