How pricing works

Kyma charges per token. Every request has:
  • input tokens for your prompt and context
  • output tokens for the model’s response
No monthly fee, no seat fee, no contract. Prices below are per 1 million tokens. For the live canonical table, use GET /v1/models or GET /v1/credits/pricing.

Pricing per model

Cheapest useful models

Use these for bulk automation, extraction, and simple workloads.

Balanced value

Use these when you want strong quality without flagship pricing.

Flagship / premium

Use these when quality or capability matters more than cost. Rows showing · cached print the cached input price inline (10% of normal input — applies to repeated system prompts and tool definitions on caching-enabled models; see prompt caching).

Long-context & multimodal

Use these when context length or image input is the bottleneck. Perplexity’s Sonar models run a live web search on every request and return cited answers. They bill two components on the same request: normal token pricing plus a flat web-search fee for the live search. The web-search fee is flat per request — it does not scale with tokens — so a short sonar question is dominated by the search fee, not the tokens. Every response’s usage.cost already includes it. (The GET /v1/pricing catalog lists the per-token prices above; the flat search fee is applied per request at billing time, not as a catalog field.) Standard models have no per-request fee; use Sonar only when you actually need fresh web data.

Image generation

Image models bill per image, not per token. Cost shown is what you pay; the underlying provider price is marked up 1.35×. See the Image Generation guide and the API reference. A request with n: 4 is billed as 4 images. gpt-image-2 requests can opt into quality: low/medium/high per call; the hold books the right tier amount up front so high-quality requests reserve $0.297 (no refund-and-rebill drift). Holds refund in full if generation fails.
Use Which model should I use? to pick by task rather than by price.

What does a typical request cost?

With the $0.50 signup credit, you can make hundreds or thousands of requests depending on model choice.

How billing works

  1. Before each request, Kyma holds an estimate from your balance
  2. After the response completes, Kyma calculates the real token cost
  3. If the real cost is lower, the difference is refunded automatically
You pay for actual usage, not the initial estimate.

Credits

Credits never expire. Auto top-up is supported in the dashboard.

Video generation

Per-second models scale with the duration parameter (default 5s, max 10–15s by model). Hailuo bills flat per call. See Video Generation. Live source: GET /v1/pricing (video rows).

Audio

Audio splits by capability — transcription, understanding, realtime, TTS, music, voice, SFX. Speech-to-text (per minute, 1-min minimum billable) Audio understanding (per minute) Realtime translation (per minute) TTS (per 1k characters) Music Voice services & SFX (flat per call) Live source: GET /v1/pricing (audio rows).

Prompt caching

Cached input tokens are charged at 10% of the normal input price. That means:
  • repeated system prompts get much cheaper
  • tool definitions become cheaper over repeated runs
  • long agent sessions benefit the most

Rate limits

Kyma uses a tier-based system similar to xAI and Anthropic-style paid access: your tier increases based on total credits purchased, not lifetime usage. RPM = requests per minute Per-model RPM = how many requests per minute a single model can take TPM = tokens per minute across your account There are no daily or monthly caps. Your balance and tier are the real limits.

What happens when you hit a limit?

Out of credits
Too many requests
The Retry-After header tells you when to retry.

How to spend less

  • Use cheaper models for extraction, routing, and repetitive automation
  • Use qwen-3-32b instead of a flagship if you mainly need fast coding help
  • Use gemini-2.5-flash only when long context is the real need
  • Use deepseek-r1 only when the task truly needs deeper reasoning
  • Purchase credits if you need higher rate limits, not just more balance
