Description: fastText vectors trained on Araneum Russicum Maximum corpus (about 10 billion words). The model contains 196K words and 403K 3-4-5-grams.

Preprocessing: The corpus was lemmatized with Mystem.
Parameters: vector size 300, window size 5
Code example:

$ tar xzf araneum_none_fasttextcbow_300_5_2018.tgz
$ python3
model = gensim.models.KeyedVectors.load('araneum_none_fasttextcbow_300_5_2018.model')
for n in model.most_similar(positive=['уточка']):
    print(n[0], round(n[1], 3))
чуточка 0.754
досочка 0.726
пинеточка 0.724
деточка 0.704
улиточка 0.693
нямочка 0.693
белочка 0.69
квочка 0.69
выточка 0.689
козочка 0.683

One can lemmatize Russian texts before using this model, with the help of pymystem:

def tag(word):
    from pymystem3 import Mystem
    m = Mystem()
    processed = m.analyze(word)[0]
    lemma = processed["analysis"][0]["lex"].lower().strip()
    return lemma

tag('стульев')
стул

I got the following error:

>>> model = gensim.models.fasttext.FastText.load('araneum_none_fasttextcbow_300_5_2018.model')

During handling of the above exception, another exception occurred:

@andrei-q Gensim fastText code has been refactored since the time this issue was created.
In the recent versions of Gensim, you should use gensim.models.KeyedVectors.load() to load this model.
I've changed the code snippet above accordingly.

Thanks. It works
