Frequently asked questions

Replicate FAQs

How does Replicate pricing work?

Replicate charges per prediction based on the compute time used. Pricing varies by model and GPU type. Text models are billed per token; image models per image. Some models are free with rate limits.

What types of models does Replicate support?

Replicate supports text (Llama, Mistral), image (Stable Diffusion, FLUX), audio (Whisper), video, and many other model types. It has one of the broadest model catalogs of any inference platform.

Can I deploy my own model on Replicate?

Yes. Replicate lets you package and deploy custom models using Cog, their open-source model packaging tool. Once deployed, your model gets a public API endpoint.

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.
