Fully open 8B multilingual LLM supporting 1800+ languages with 65K context. Trained on compliant open data. Apache 2.0, EU AI Act compliant.
Apertus 8B Instruct by publicai is currently listed from a single provider. Its reference price is $0.10 per 1M input tokens and $0.20 per 1M output tokens.
Artificial Analysis rates it 4.8 on the Intelligence Index. Against its lowest blended price of $0.125 per 1M, that is roughly 38 index points per dollar, which is the value ratio the leaderboards rank on.
The context window is 65,536 tokens, with an output limit of 8,192 tokens. It supports tool use. The weights are open, so it can also be self-hosted or served through a gateway of your choice. Its training knowledge cuts off at 2025-09.
Quality is independently evaluated by Artificial Analysis. Speed/latency are model-level medians.

Sorted by blended price (input×0.75 + output×0.25) asc. The official channel always shows regardless of rank. Whether a gateway's low price is actually usable can't be verified.
Price history accumulates from each data sync; currently only 1 sample(s) (2026-08-17). Each future sync adds a point, and once accumulated a line is drawn here.
Individual evaluations run by Artificial Analysis, on the same reasoning tier as the intelligence score above. Each benchmark has its own task set and harness, so rows are not comparable with one another. The Intelligence Index above draws on a different, newer set of evaluations.
