How this calculator works
Each blog post or article generation requires ~500 input tokens (the prompt, topic, keywords, style instructions) and ~2,000 output tokens (the article, ~1,500 words). Content generation is output-token-heavy, so models with cheap output pricing are most cost-effective. Longer articles or multi-section pieces will increase output token usage proportionally.
Formula: cost = (input_tokens × input_price_per_Mtok + output_tokens × output_price_per_Mtok) × quantity / 1,000,000
All prices are per million tokens, sourced directly from official provider pricing pages. No fabricated numbers — every model in the table links to its detail page, which cites the official pricing source.
Frequently asked questions
How much does it cost to generate 500 blog posts with an LLM API?
It depends on the model. Content generation is output-heavy (~500 input / ~2,000 output tokens per article), so output price is the main driver. The calculator above computes the exact current cost for every model, cheapest-first, from live per-million-token pricing; the table above ranks models by total cost for this output-weighted workload.
Which LLM API is cheapest for content generation?
For bulk generation the cheapest models are those with low output pricing — the calculator ranks them cheapest-first for this output-heavy workload, so the top of the table is your lowest cost. Higher-tier models produce more polished copy at a higher price; compare exact figures to decide.
How are content generation token costs calculated?
Each article uses ~500 input tokens (prompt) and ~2,000 output tokens (article text). Total cost = (input_tokens × input_price + output_tokens × output_price) × number_of_articles. Prices are per million tokens from official provider pricing pages.
