Ling-lite-1.5-2506
Model Overview
We are excited to introduce Ling-lite-1.5-2506, the updated version of our highly capable Ling-lite-1.5 model.
Ling-lite-1.5-2506 boasts 16.8 billion parameters with 2.75 billion activated parameters, building upon its predecessor with significant advancements across the board, featuring the following key improvements:
- Reasoning and Knowledge: Significant gains in general intelligence, logical reasoning, and complex problem-solving abilities. For instance, in GPQA Diamond, Ling-lite-1.5-2506 achieves 53.79%, a substantial lead over Ling-lite-1.5's 36.55%.
- Coding Capabilities: A notable enhancement in coding and debugging prowess. For instance,in LiveCodeBench 2408-2501, a critical and highly popular programming benchmark, Ling-lite-1.5-2506 demonstrates improved performance with 26.97% compared to Ling-lite-1.5's 22.22%.

Quickstart
🤗 Hugging Face Transformers
Here is a code snippet to show you how to use the chat model with transformers:
from transformers import AutoModelForCausalLM, AutoTokenizer
model_name = "inclusionAI/Ling-lite-1.5-2506"
model = AutoModelForCausalLM.from_pretrained(
model_name,
torch_dtype="auto",
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)
prompt = "Give me a short introduction to large language models."
messages = [
{"role": "system", "content": "You are Ling, an assistant created by inclusionAI"},
{"role": "user", "content": prompt}
]
text = tokenizer.apply_chat_template(
messages,
tokenize=False,
add_generation_prompt=True
)
model_inputs = tokenizer([text], return_tensors="pt").to(model.device)
generated_ids = model.generate(
**model_inputs,
max_new_tokens=512
)
generated_ids = [
output_ids[len(input_ids):] for input_ids, output_ids in zip(model_inputs.input_ids, generated_ids)
]
response = tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0]
