GPT-4.1 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 tool calling and image input, as GPT-4.1 does.
LiveBench hasn't published a run for GPT-4.1. The strongest benchmarked model at a similar or lower price is GPT-6.1 Sol, scoring 84.1 overall.
GPT-4.1: no published LiveBench run, $3.50 per 1M blended tokens, about $1,480/mo for a RAG assistant.
Benchmarked models at or below its price
GPT-4.1 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.

GPT-4.1 alternatives FAQ
What is the best alternative to GPT-4.1?
GPT-6.1 Sol. 14% more expensive. Every suggestion supports tool calling and image input, like GPT-4.1.
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 GPT-4.1 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.
