What the router does with the pair

Grok 4.5 is both cheaper and stronger on the intelligence index, so with both in the catalogue the router sends it almost everything; Grok 4.7 earns a request only on something it alone offers - a longer context, a modality, a data boundary or a region your rules require.

Price a request Playground

yaml

# targets.yaml - both models as routing targets (metadata.model links each to the catalogue entry)
targets:
  - { id: grok-4.5, kind: llm, metadata: { model: x-ai/grok-4.5 } }
  - { id: grok-4.7, kind: llm, metadata: { model: x-ai/grok-4.7 } }

# rules.yaml - the cheaper model by default, the stronger one when the request is hard
rules:
  - name: simple-requests-stay-cheap
    when: { max_complexity: 0.45 }
    prefer: [grok-4.5]
    weight: 0.8

Frequently asked

Is Grok 4.5 cheaper than Grok 4.7?: No - both list at $3.00 per million tokens blended (three input tokens per output token).
Which is better, Grok 4.5 or Grok 4.7?: On the Artificial Analysis intelligence index Grok 4.5 scores higher (39 against 35). "Better" depends on the task: the coding and agentic indexes below and the abilities row may point the other way for your requests.
Which has the longer context window?: Both accept 500K tokens.
Can I use Grok 4.5 and Grok 4.7 together?: Yes. Declare both as targets and OpenSmartRoute picks one per request on quality for the task, price and your rules - the cheaper model for the requests it can answer, the stronger one for the rest - and records why in the trace.

The model catalogue

Which LLM is the cheapest for our workload?: The best-for pages rank the live catalogue per task by the index that measures it, and the router picks the cheapest model that meets your quality rule for each request.
How much can we save on our LLM bill?: On the public benchmark the router saved 89% against sending everything to the reference model. Import last month's provider bill on the bill page and the estimate is computed on your own traffic before you change a line of code.
How often do model prices change?: The catalogue is refreshed from the vendors' price lists; each model page shows the date of its data.
