• The core functionality of Sumr is free.
• You use your own OpenAI key, meaning you pay only for what you actually used.
• OpenAI charges for the API usage, but the costs are very low.
• Let’s define “low”.

TL;DR:

It’s about $0.0005 USD for summarizing a 1000-word article.
Meaning you need to summarize ~20 articles of that size to pay 1 cent.

OpenAI API Usage Costs Break Down

Currently we utilize GPT-4o-mini model to process requests. Every request will be processed by OpenAI and billed to your OpenAI account.

OpenAI pricing for GPT-4o-mini model:

• $0.00015 per 1,000 input tokens (what you are sending to the API).
• $0.0006 per 1,000 output tokens (what you are receiving from the API).
• 1,000 tokens ≈ 750 words

Example Costs

Let’s see how much will be for a 1000-word article:

• ≈1000 words with system prompts is less than 1500 tokens ≈ $0.0002295 for input
• 500 tokens (hard upper limit for the summary) ≈ $0.0003 for output (maximum)
• So in total ≈ $0.0005295 for a 1000-word article

This is what a 1000 words article look like:

Text in our user manual is about 1300 words. So the price of summarizing the user manual is $0.0006. Which means you need to summarize ~17 pages of that size to pay 1 cent.

Advanced Features (Coming Soon)

Optional features will be available as a one-time purchase. We will announce the pricing when the features are ready.

If we will see demand for people who don’t want to bother with API keys, we might offer a generous subscription model at some point to cover our the API requests and infrastructural cost. We will announce it separately.
