Tiny Aya L2-Thinker

Tiny Aya L2-Thinker is a 3.35-billion-parameter multilingual reasoning model released with open weights. It supports in-language reasoning in 44 languages plus English, with additional language coverage for instruction data, and can be used for mathematics, science, general reasoning, instruction following, and multilingual generation.

What it does

People can use it to solve tasks such as math, cultural reasoning, instruction following, and open-ended writing while inspecting reasoning traces in the prompt language.
