Common questions

What is the cheapest LLM API in 2026?

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, and this is where the real savings are. Route simple classification and extraction tasks to budget models like Claude Haiku 4.5, and reserve expensive models for complex reasoning. The trick is finding the cheapest model that meets your quality bar for each task type. Test thoroughly - cheap models that seem fine on 10 examples may fail at scale.

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.

How do I choose between cheap LLM APIs for my project?

Start by identifying your task complexity. For simple extraction and classification, Claude Haiku 4.5 offers the lowest absolute token cost. For tasks that need stronger reasoning at a budget price, DeepSeek V3 delivers the best quality per dollar. LLMWise lets you route different tasks to different models automatically, combining both for maximum savings.
