Do not stop at token price

The number that matters when buying credits

For LLMFly AI credits, use the current price shown in Model Plaza—not the provider reference table above. Then send a small request and check the usage record before projecting monthly spend.

A usable monthly estimate

request.example
monthly_cost =
  (input_tokens / 1_000_000 * input_rate) +
  (output_tokens / 1_000_000 * output_rate) +
  cache_and_tool_charges + retry_cost

Costs teams often miss

  • Conversation history resent on every turn.
  • Reasoning tokens counted as output.
  • AI agent tool loops and validation calls.
  • Retries after 429 or transient upstream failures.
  • Cache writes, cache reads, and storage when the model supports them.

How much does one LLM API request cost?

Token cost = uncached input tokens × input price per million ÷ 1,000,000 + output tokens × output price per million ÷ 1,000,000, plus cache, tools, and other charges. Use a provider pricing calculator above, select your model, and enter input and output token counts to estimate a request.

How much do API cache reads and cache writes cost?

Cache prices depend on the exact model. The pricing table lists cache reads, cache writes, and applicable 1-hour write rates per million tokens. Reads and writes are separate billing categories; a missing rate or dash does not mean free usage.

Should I apply the discount multiplier to LLMFly AI prices again?

No. The LLMFly AI column and FAQ prices already include the group multiplier. Provider prices are shown separately for comparison. Actual charges depend on your account's applicable rates and usage records.
