Sonar alternatives
Cheaper models that come close, budget substitutes, and the cheapest step up — chosen on published LiveBench scores and live list price, never on our opinion. Every model here supports image input, as Sonar does.
LiveBench hasn't published a run for Sonar. The strongest benchmarked model at a similar or lower price is DeepSeek V4.1 Flash 1017, scoring 74.0 overall.
Sonar: no published LiveBench run, $1.00 per 1M blended tokens, about $860.00/mo for a RAG assistant.
Benchmarked models at or below its price
Sonar has no published LiveBench run, so these are the highest-scoring benchmarked models priced no more than 25% above it — a known quantity to test against.

Sonar alternatives FAQ
What is the best alternative to Sonar?
DeepSeek V4.1 Flash 1017. 48% cheaper. Every suggestion supports image input, like Sonar.
How alternatives are chosen
- Scores — LiveBench release 2026-10-25. Only models with a published run are suggested on quality; a missing model means “not evaluated”, not “worse”.
- Prices — live list prices from OpenRouter, blended 3:1 input:output. Monthly figures price a RAG assistant with the published cached-input rate where there is one.
- Same job — suggestions must support every capability Sonar has among tool calling and image input. Other listings of the same model (free or batch tiers) are variants, not alternatives, and are left out.
A few points on a public benchmark can hide large differences on your own tasks. Shortlist here, then decide with an eval — how to build one.
