Prices in US dollars per 1M tokens, live from the catalog, with each lab's list price struck through. 10K requests is 10,000 requests of 2,000 tokens in and 500 out, at each price. You save is on output tokens.

Spend less

Five ways to pay less. On any LLM API.

Use the smallest model that passes your tests. The spread is wide: for the same workload, Claude Fable 5.1 costs about 155 times as much as DeepSeek V4 Flash 0731. Run your own prompts through two or three tiers before you settle on one.

Cache what repeats. Most models bill input they've seen recently for less: Claude Sonnet 5.5's cached input costs $0.09 per 1M tokens against $0.90 for new input. Put the long part of the prompt that doesn't change (instructions, tools, documents) first.

Cap the output. Output costs more than input: on the median model here, 5 times as much per token. Set max_tokens, ask for short answers, and use structured output where it fits.

Let a router pick. Zurelay Auto sends everyday requests to low-cost models and harder ones to stronger models, and bills the price of the model that answered.

Pay less for the same model. Every chat model on Zurelay costs 18–90% less than its lab's list price: the same model name, through the OpenAI and Anthropic SDKs, with no subscription. How every route is verified.

FAQ

Cheap LLM API questions.

Anything else? Ask our team and we’ll answer by email.

What is the cheapest LLM API?

Of the 45 chat models on Zurelay right now, DeepSeek V4 Flash 0731 from DeepSeek costs the least for a typical workload: $0.029 input and $0.087 output per 1M tokens, so 10,000 requests of 2,000 tokens in and 500 out cost $1.02. The cheapest model isn't always the best value: the table above ranks every model, and each one's page has its benchmarks.

What is the cheapest Claude API?

Claude Haiku 5.5 is the lowest-priced Claude model on Zurelay, at $0.04 input and $0.20 output per 1M tokens. Every Claude model is 46–65% below Anthropic's list price here, through Anthropic's Messages API and an OpenAI-compatible endpoint, so Claude Code and both SDKs work.

What is the cheapest GPT API?

GPT-6 Luna is the lowest-priced GPT model on Zurelay, at $0.025 input and $0.125 output per 1M tokens, below OpenAI's list price. Code written for the OpenAI SDK works once you change the base URL and the key.

How can I use a top model like Claude Opus or GPT-6 Astra for less?

Pay less per token for the same model. Every chat model on Zurelay costs 18–90% less than its lab's list price, with the same model name, through the same SDKs. Then cut the tokens: cache the parts of your prompt that repeat, cap the output, and send easy requests to a smaller model.

Is a cheap LLM API safe to use?

The real risk with a cheap reseller is getting a different or older model than the one you pay for. Zurelay tests every route before it serves requests and every day after, with identity, dated-knowledge and reasoning checks, and takes a route out of rotation when it fails. Failed attempts move to another route and aren't billed.

Why are these prices below the labs' own?

Model capacity is often bought ahead, through prepaid credits, committed-spend contracts and volume tiers, and not all of it gets used. Sellers offer it below list price. Zurelay tests each route, pools several per model and sends every request to one that is available and verified.
