kobert

by Kong konghyul/kobert

kobert is an open-weight model for text classification from Kong. It has 92M parameters and a 512-token context. At 16-bit it needs about 0.2 GB of GPU memory, which fits on 1x MI300X from $1.85 an hour, at the lowest prices in the SAVRN Index.

This model is a fine-tuned version of skt/kobert-base-v1 on the None dataset. It achieves the following results on the evaluation set: The following hyperparameters were used during training: - learningrate: 2e-05 - trainbatchsize: 16 - evalbatchsize: 16 …

Runs On

What it takes to serve kobert (92M 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 18, 2026.

Questions About kobert

How much GPU memory does kobert need?

About 0.2 GB at 16-bit and 0.1 GB at 4-bit: the weights (92M parameters) plus a working margin. A long context needs more.

What is the cheapest GPU to run kobert 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.

What is kobert's context length?

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