Trendyol LLM 8B T1

Trendyol-LLM-8B-T1 is an 8-billion-parameter chat and reasoning model released by Trendyol on July 17, 2025, built on Qwen3-8B and fine-tuned on large-scale Turkish e-commerce datasets. Its goal is advanced reasoning in Turkish while preserving the base model's English capability.

It supports dual operation modes: /think for explicit chain-of-thought and /no_think for concise answers. Out of the box it covers instruction following, summarization, coding tasks, text and review classification, and attribute extraction for catalog enrichment, with a native 32k-token context. It is released under Apache-2.0, free for commercial and research use. Independent evaluations have benchmarked it against Turkish-specialized and multilingual baselines.
