Frequently asked questions
- How does TokenAtlas estimate AI costs?
- It multiplies the input and output token volumes you enter by each model's published per-million-token price, then projects that to your request volume.
- How accurate are cost estimates?
- Estimates are based on published list prices and the token volumes you enter, so they're only as accurate as your inputs. Always reconcile against your provider invoice for accounting.
- Does TokenAtlas require API keys?
- No. TokenAtlas never needs provider API keys, secrets, or credentials — please don't paste them anywhere in the product.
- Which AI models are supported?
- 11 models across 6 providers: OpenAI, Anthropic, Google, Mistral, Groq and DeepSeek.
- Can I model costs before deployment?
- Yes — that's the primary use case. Because estimates come from workload inputs rather than live traffic, you can model a feature before any of it runs in production.
- Is TokenAtlas free to try?
- Yes. The calculator is free to use, and a free account includes 20 calculations per day and 3 saved scenarios. No card required.
Estimates are for planning only. Pricing reflects published API rates.
