Common questions

What is the cheapest LLM API in 2025?

Claude Haiku 4.5 and DeepSeek V3 are the cheapest production-quality LLM APIs. Haiku offers the lowest absolute cost per token, while DeepSeek V3 offers the best quality per dollar for complex tasks like coding and math.

Can I use cheap and expensive models together?

Yes. LLMWise lets you route requests to different models based on task complexity. Use Compare mode to find which cheap model handles your simple queries well enough, then reserve premium models for tasks that need frontier intelligence.

Is self-hosting an LLM cheaper than using an API?

At very high volume, self-hosting Llama 4 Maverick can be cheaper. However, for most teams, the operational overhead of GPU infrastructure makes API-based models like Claude Haiku 4.5 and DeepSeek V3 more cost-effective until you reach millions of requests per day.
