What it's best for
Best for complex drafting and reasoning on a budget: a large model's quality on nuanced instructions, at open-weight prices well below frontier rates. 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 Qwen 2.5 72B Instruct 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.
