How to estimate GPT costs
Paste your prompt
Drop a representative prompt into the left editor. Tokens are estimated at ~4 chars/token.
Set expected output tokens
How long do you expect the response to be? Default 500 covers a paragraph or two.
Set calls per day
How often does this prompt run? 100 = trial-scale, 10000+ = production-scale.

Per-call, per-day, per-month, per-year totals update live as you tweak inputs.
Frequently asked questions
We use ~4 chars/token, accurate to about ±20%. For exact counts use the model-specific token counter such as the OpenAI token counter.

Toggle "Cached input" for a 90% input discount — this is approximate and varies by provider. OpenAI's prompt caching kicks in for repeated prefixes ≥ 1024 tokens.
Provider tokenizers can differ slightly from our estimate; system prompts and tool definitions also count toward input; rates change over time. Treat this as a planning tool, not a billing replica.
About DeepSeek V3 API pricing
DeepSeek V3 is a high-quality open-weights model from DeepSeek AI, available via API at extremely low rates: $0.27/1M input, $1.10/1M output. Quality benchmarks rival GPT-4o-class models at roughly 10% of the cost.
When DeepSeek V3 makes sense
- Cost-sensitive production workloads (chatbots, batch jobs).
- Open-weights option: you can self-host for total control.
- Solid reasoning and coding ability.
Tradeoffs
- 64K context is smaller than GPT-4o (128K) or Gemini (1M).
- Tool / function calling ecosystem less mature than OpenAI.
- Geographic / regulatory considerations for some users.
