What the router does with the pair

The two measure the same on the intelligence index, so the router treats them as peers and lets price, observed latency and your outcomes decide: gpt-oss-20b wins on cost, and a few bad outcomes on either move the next requests to the other.

Frequently asked

Is DeepSeek V3 0324 cheaper than gpt-oss-20b?: No. DeepSeek V3 0324 lists at $0.29 in / $1.14 out per million tokens, gpt-oss-20b at $0.02 in / $0.09 out; blended, gpt-oss-20b is the cheaper one.
Which is better, DeepSeek V3 0324 or gpt-oss-20b?: On the Artificial Analysis intelligence index gpt-oss-20b scores higher (10 against 10). "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?: DeepSeek V3 0324 - 164K tokens against 131K.
Can I use DeepSeek V3 0324 and gpt-oss-20b 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.
