Frequently asked questions
Fireworks AI FAQs
What models does Fireworks AI offer?
Fireworks AI hosts Llama 3.3 70B, DeepSeek R1, Mixtral, and other popular open-weight models. They focus on production-ready models with optimised inference rather than the broadest possible catalog.
How much does Fireworks AI cost?
Llama 3.3 70B costs $0.90/1M tokens (input and output). DeepSeek R1 is $3.00/1M input and $8.00/1M output. Pricing is competitive with other inference API providers.
How does Fireworks AI compare to Together AI?
Fireworks AI offers faster throughput (320 vs 190 tokens/sec on Llama 3.3 70B) and stronger production reliability. Together AI has a larger model catalog and fine-tuning support. Choose Fireworks for production speed, Together for model variety.
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.
