naver-hyperclovax / HyperCLOVAX-SEED-Text-Instruct-1.5B

Overview

HyperCLOVAX-SEED-Text-Instruct-1.5B is a model developed by NAVER that can understand and generate text. It demonstrates competitive performance on major benchmarks related to Korean language and culture. In addition, it supports a context length of up to 16k tokens, enabling it to handle a wide range of tasks.

Basic Information

• Model Architecture: Transformer-based architecture (Dense Model)
• Number of Parameters: 1.5B
• Input/Output Format: Text / Text (both input and output are in text format)
• Context Length: 16k
• Knowledge Cutoff Date: The model was trained on data prior to August 2024.

Training and Data

The training data for HyperCLOVAX-Seed-Instruct-1.5B consists of diverse sources, including high-quality datasets. The training process was carried out in four main stages: Pretraining Stage 1, where the model learns from a large volume of documents; Pretraining Stage 2, which focuses on additional training with high-quality data; Rejection sampling Fine-Tuning (RFT), aimed at enhancing the model’s knowledge across various domains and its complex reasoning abilities; and Supervised Fine-Tuning (SFT), which improves the model’s instruction-following capabilities. Furthermore, due to the characteristics of smaller models, vulnerability to long-context handling was observed. To address this, reinforcement for long-context understanding was incorporated from the pretraining stages through to the SFT stage, enabling the model to stably support context lengths of up to 16k tokens.

inputs = tokenizer.apply_chat_template(chat, add_generation_prompt=True, return_dict=True, return_tensors="pt")
output_ids = model.generate(**inputs, max_length=1024, stop_strings=["<|endofturn|>", "<|stop|>"], tokenizer=tokenizer)
print(tokenizer.batch_decode(output_ids))
