Tick above each rail is this model, below it the other 69. Dashed rule is the field median, solid is its best. Better is left; the axis stops at the 90th percentile, so a few models sit past its right edge.

When to use DeepSeek R1

Updated 2026-07-29

Where this model earns its cost — and where it doesn't.

DeepSeek R1 is a frontier reasoning model from DeepSeek that processes text inputs and returns text outputs. It is designed for tasks that require deep logical deduction, mathematical problem solving, and tool use, with native support for structured outputs.

On Kyma, the model runs behind automatic failover routing and returns exact request costs in the usage.cost field. It operates with a 64,000-token context window and a maximum output length of 32,768 tokens. The reasoning alias resolves directly to this model.

This model does not support vision, prompt caching, or multimodal inputs. Because it runs on a slow speed tier, it is not suitable for latency-sensitive applications. Input and output tokens are billed per-token at the platform's listed rates.

Math & Logic Problems

Solve complex mathematical and logical reasoning tasks with explicit step-by-step traces.

Document Analysis

Extract structured insights and perform deep textual analysis across long documents.

Tool-Enabled Workflows

Drive multi-step agent tasks that require explicit reasoning and function calling.

Not ideal for: Avoid this model for real-time conversational interfaces, vision-based tasks, or applications that require prompt caching and low-latency responses.

FAQ

Common questions about this model.

What is the context window of DeepSeek R1?

DeepSeek R1 has a 64K-token context window — roughly 94 pages of text in a single request.

How much does the DeepSeek R1 API cost?

$0.7425 per 1M input tokens and $2.957 per 1M output tokens. No subscription; you pay only for what you use.

Does DeepSeek R1 support function calling?

Yes — DeepSeek R1 supports tool/function calling and structured outputs (JSON mode), so it works with agent frameworks out of the box.

Are the weights for DeepSeek R1 publicly available?

Yes. DeepSeek publishes DeepSeek R1's weights as deepseek-ai/DeepSeek-R1-0528, so you can download and run the model yourself (https://huggingface.co/deepseek-ai/DeepSeek-R1-0528, read 2026-08-14). Kyma serves it because it is convenient and has failover behind it, not because it is the only way to reach it.

How do I use DeepSeek R1?

Kyma is OpenAI-compatible: point your SDK's base URL at https://kymaapi.com/v1, use your Kyma API key, and set the model to deepseek-r1. Signing up is free and includes $0.50 of credit — no card required.

Does this model support image inputs?

No, it is strictly a text-only model and does not support vision or multimodal processing.

How fast does it generate text on Kyma?

It runs in the slow speed tier, well behind standard chat models — that is the cost of generating an explicit reasoning trace before the answer.

Can I use prompt caching with this model?

No, the model does not support prompt caching. Repeated prompt prefixes will be billed at the standard input rate.
