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
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.
