T-lite-it-2.1-GGUF

🚨 Users are advised to exercise caution and are responsible for any additional training and oversight required to ensure the model's responses meet acceptable ethical and safety standards. The responsibility for incorporating this model into industrial or commercial solutions lies entirely with those who choose to deploy it.

This repository contains T-lite-it-2.1 converted to the GGUF format with llama.cpp.
See the original BF16 model here: t-tech/T-lite-it-2.1.

Description

T-lite-it-2.1 is an efficient Russian model built upon the Qwen 3 architecture, featuring significant improvements in instruction following and adds support for tool-calling capabilities — a key advancement over T-lite-it-1.0, which lacks tool-use support. Outperforms Qwen3-8B in tool calling scenarios, which is essential for agentic applications. Built for both general tasks and complex workflows, with higher Russian text generation throughput enabled by optimized tokenizer.

NOTE: This model supports only non-thinking mode and does not generate <think></think> in its output. Meanwhile, specifying enable_thinking=False is no longer required.

Available quantisations

Recommendation: choose the highest-quality quantisation that fits your hardware (VRAM / RAM).

Filename (→ `-gguf`)	Quant method	Bits	Size (GB)
`T-lite-it-2.1-q8_0`	Q8_0	8	8.7
`T-lite-it-2.1-q6_k`	Q6_K	6	6.7
`T-lite-it-2.1-q5_k_m`	Q5_K_M	5	5.9
`T-lite-it-2.1-q5_k_s`	Q5_K_S	5	5.7
`T-lite-it-2.1-q5_0`	Q5_0	5	5.7
`T-lite-it-2.1-q4_k_m`	Q4_K_M	4	5.0

Size figures assume no GPU off-loading. Off-loading lowers RAM usage and uses VRAM instead.
