rubert-tiny-toxicity

by David Dale cointegrated/rubert-tiny-toxicity

rubert-tiny-toxicity is an open-weight model for text classification from David Dale, released under MIT License. It has 12M parameters and a 512-token context. At 16-bit it needs about 0 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index. It draws 451.6k downloads a month.

This is the cointegrated/rubert-tiny model fine-tuned for classification of toxicity and inappropriateness for short informal Russian texts, such as comments in social networks.

What it takes to serve rubert-tiny-toxicity (12M parameters): the memory its weights need at each precision, and the cheapest way to rent enough data-center GPUs to hold them.

Memory is the weights at that precision plus 20% for the runtime and a short context; a long context needs more. Prices are the lowest on-demand hourly rates in the SAVRN Index, read Oct 14, 2026.

SAVRN's Notes on rubert-tiny-toxicity

Moderating Russian-language comments is the job, and the model is small enough to live inside the comment pipeline itself. David Dale trained it to return five labels on a short informal text: non-toxic, insult, obscenity, threat, and dangerous. Twelve million parameters in three layers come to 94 MB of float32 weights, and our page rounds the 16-bit memory need to 0.0 GB. The cheapest listed setup, one MI300X at $1.85 an hour, is more card than this needs; it belongs on a spare slice of something already running.

MIT terms permit commercial use, modification and redistribution provided the copyright and permission notices ride along, so a moderation vendor can ship it inside a product. Check the lineage, it is derived from cointegrated/rubert-tiny, and the 512-token context, which means long threads get split before scoring. It was last updated August 3, 2026, more than four years after its March 2022 release.

Model Card

By David Dale, published under mit, revision 5d37eff84486.

This is the cointegrated/rubert-tiny model fine-tuned for classification of toxicity and inappropriateness for short informal Russian texts, such as comments in social networks.

The problem is formulated as multilabel classification with the following classes: - non-toxic: the text does NOT contain insults, obscenities, and threats, in the sense of the OK ML Cup competition. - insult - obscenity - threat - dangerous: the text is inappropriate, in the sense of Babakov et.al., i.e. it can harm the reputation of the speaker.

A text can be considered safe if it is BOTH non-toxic and NOT dangerous.

Usage

The function below estimates the probability that the text is either toxic OR dangerous:

Questions About rubert-tiny-toxicity

How much GPU memory does rubert-tiny-toxicity need?

About 0 GB at 16-bit and 0 GB at 4-bit: the weights (12M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run rubert-tiny-toxicity on?

At 16-bit, 1x MI300X from $1.85 an hour; at 4-bit, 1x MI300X from $1.85 an hour, at the lowest on-demand prices the SAVRN Index lists.

Can I use rubert-tiny-toxicity commercially?

Yes. rubert-tiny-toxicity is released under MIT License. The MIT License is a short permissive license. It permits commercial use, modification and redistribution, provided the copyright notice and permission notice are included.

What is rubert-tiny-toxicity's context length?

512 tokens, from the maximum position embeddings in its published configuration.
