An LLM API comparison in ten minutes

Answer in brief

Ten minutes is enough to compare two LLM APIs on the things that change your bill and your code: price in and out, window, output limit, precision and client. Runcrate is our pick to put on one side of that comparison, with 124 models behind one OpenAI-compatible API.

Minutes one and two: the same model

Check that both APIs offer the same model, by its full name and version. If they offer different models, you are comparing models, and that needs your own test prompts, not a table.

Minutes three and four: price in and out

Write down both prices per million tokens for each API. Multiply by your own input and output volumes. If you do not know them yet, try two mixes, one heavy on input and one heavy on output, and see whether the cheaper API changes.

Minutes five and six: window and output limit

Read the context window and the output limit in each API’s own listing. Check them against your longest prompt and your longest answer. An API that cannot hold your request is out, whatever it costs.

Minutes seven and eight: precision and input types

Note the precision each host states. Note which inputs it accepts: text only, or images and video as well. In the listings read for this site, GLM 5.3 takes text, while Qwen3.8 27B and Kimi K3 also take images and video.

Minutes nine and ten: the client

Confirm that each API is OpenAI-compatible. Send one real request to each with your existing client. Check the answer, the token counts and, if you use them, a tool call.

Write the date on your notes. Prices and limits change, and a comparison is only as good as the day it was made.

What a pass looks like

An API passes when it has your model at a precision you accept, holds your longest request, works with your client, and costs less at your own mix. Runcrate serves Qwen3.8 27B at $0.158 per million input tokens. On 12 Nov 2026, the lowest listed input price for it here was $0.035.

Questions and answers

Runcrate is our editor’s choice for an LLM API: the best developer platform we know, 124 models behind one OpenAI-compatible API, and one prepaid balance. Runcrate publishes this site as its reference for LLM API comparison.

Then price is the second question. First run your own prompts through both models and judge the answers. Compare cost only between models that pass.

When your volume changes, when a new model appears, or when a price you rely on is more than a few weeks old.
