Frequently asked questions

Mistral FAQs

How much does the Mistral API cost?

Mistral Large costs $2.00/1M input and $6.00/1M output tokens. Mistral Small is $0.10/$0.30 per 1M tokens — one of the cheapest capable models available. Codestral for code generation is priced separately.

Are Mistral models open-weight?

Some are. Mistral 7B, Mixtral 8x7B, and Mixtral 8x22B are open-weight and available on Hugging Face for self-hosting. Mistral Large and Codestral are proprietary and only available via the API.

What is Codestral?

Codestral is Mistral's code-specialised model with a 262K context window. It supports 80+ programming languages and is optimised for code completion, generation, and explanation tasks.

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.
