Function calling Reasoning Reasoning
DeepSeek R1 is here: Performance on par with [OpenAI o1](/openai/o1), but open-sourced and with fully open reasoning tokens. It's 671B parameters in size, with 37B active in an inference pass....
What it's best for
Best for multi-step problems where the model benefits from working through its chain of thought: maths, analysis, planning and agentic loops. Reasoning models produce (and bill for) more output tokens than plain chat models, so use them where the extra thinking pays for itself. It supports function calling, so it can drive tools and agent workflows.
Pricing
Prices updated daily — last generated 2026-07-08.
Billing is metered per request in GBP on the same monthly invoice as your apps — no subscription, no minimum. We list every model once, at the cheapest route we can serve it on; if we have to fail over to a more expensive route, we absorb the difference and your price does not change.
Where your data is processed
Requests to DeepSeek R1 are routed to a vetted partner provider and processed on that provider's infrastructure — they leave our infrastructure, and the UK-residency guarantee that applies to our UK-hosted models does not apply here. We hold the provider credentials server-side and route on cost and availability. If you need prompts that never leave our own infrastructure, use one of our UK-hosted models.
