A measurement, not a guess disguised as fact.
DeepSeek text uses the deterministic Provider-Calibrated UTF-8 Token Projection. Models without a documented vision-token specification return an unsupported state rather than a fabricated count.
Every result identifies its method and accuracy level. Pricing is refreshed from Models.dev with the bundled registry available as an offline fallback.

DeepSeek text uses the deterministic Provider-Calibrated UTF-8 Token Projection. The engine applies a DeepSeek-family bytes-per-token coefficient, then evaluates context-window utilization and current input pricing.
Reasoning, chat templates, request framing, and server-side processing can make billed usage differ from the raw-input projection shown here.
When the selected DeepSeek API model has no documented vision-token specification, the calculator returns an unsupported state instead of fabricating a count.

Frequently asked questions
How are DeepSeek tokens projected?+
The engine computes UTF-8 byte length, applies a DeepSeek-family bytes-per-token coefficient, and then evaluates context-window utilization and current input pricing.
Does DeepSeek pricing change by time of day?+
Yes. DeepSeek charges double from 01:00 to 04:00 and 06:00 to 10:00 UTC, Monday to Friday, except Chinese public holidays. This calculator uses the off-peak rates, so a request sent during peak hours costs twice the figure shown.
Can reasoning change DeepSeek token usage?+
Yes. Reasoning output, chat templates, request framing, and server-side processing can affect billed usage beyond the raw-input projection.
Can this DeepSeek calculator count image tokens?+
When the direct API model has no documented image-token specification, image calculation is marked unavailable rather than producing a fabricated number.
Why can DeepSeek API billing differ from this result?+
The provider may count request framing, reasoning, or other server-side content that is not present in the extracted input payload.
What is a token in an AI model?+
A token is a small unit of content processed by a language model. It may be a whole word, part of a word, punctuation, whitespace, or—in multimodal models—a unit assigned to an image. Different providers can split the same input differently.
How is LLM API input cost calculated?+
Input cost is calculated as input tokens divided by one million, multiplied by the selected model’s input price per million tokens. Provider tiers, cached input, tools, and message wrappers can affect final billing.
Does this tool upload my prompt, document, or image?+
No. Text, PDF and DOCX extraction, image-dimension reading, and token calculations run in your browser. Zero prompts, document contents, or uploaded images are sent to TokenCalculator.dev or another calculation server.
Are the token counts exact?+
OpenAI text counts use the matching local BPE encoding. Other providers are clearly labeled estimates unless they publish a deterministic local formula. Image counts use provider-published rules.
How do I count tokens in a PDF or Word document?+
Attach a text-based PDF or DOCX file and the browser extracts its readable text locally, then counts it with every selected provider model. Scanned or encrypted PDFs require OCR and are not supported.
Can I calculate image tokens and vision-model cost?+
Yes. Add a PNG, JPEG, WebP, or GIF. For supported vision models, the calculator reads its pixel dimensions locally and applies the provider-published image token formula. It reports unavailable instead of inventing a value when a provider has no documented rule.
Why can the API report a slightly different count?+
Providers can add message wrappers, system instructions, tools, or model-specific processing. The accuracy badge and methodology explain what this calculator includes.
