Tool-calling models — models that call your functions
Models that can decide to call a function you defined and use the result. This is the line between a chatbot and software: it is what lets a model query your database, create a record, or take an action instead of describing one.
Agent loops multiply your token bill
A tool-calling conversation is not one request. The model asks for a tool, you answer, it asks again — and the whole history is resent every time, so a five-step loop can cost far more than five simple calls. This is where per-end-user budgets stop being a nice idea and start being the thing that prevents one customer from spending your margin in an afternoon.
Fallbacks must keep the capability
If your request defines tools and the fallback model cannot call them, the failover does not save you — it swaps an outage for a wrong answer. odnoga checks capability compatibility when it builds a routing chain, so a chain that would silently drop tool calling is rejected when you configure it rather than discovered in production.
Vendor cost is the list price. Your price is that plus your plan margin — the same figures that appear on your invoice.
