What a month costs

List price times tokens for three typical workloads; your mix of input and output decides which model's pricing suits you.

What the router does with the pair

Grok 4.7 takes the short and general requests - at $3.00 blended it is the default - and GPT-6 Sol the ones whose complexity or quality floor rules the cheaper model out. The split is per request, not per app, and every decision carries the scores for both.

Frequently asked

Is GPT-6 Sol cheaper than Grok 4.7?: No. GPT-6 Sol lists at $2.00 in / $10.0 out per million tokens, Grok 4.7 at $2.00 in / $6.00 out; blended, Grok 4.7 is the cheaper one.
Which is better, GPT-6 Sol or Grok 4.7?: On the Artificial Analysis intelligence index GPT-6 Sol scores higher (48 against 46). "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?: GPT-6 Sol - 1.1M tokens against 500K.
Can I use GPT-6 Sol 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.
