Cassiopeia-Qwen-14B is based on the Qwen 2.5 14B modality architecture, designed to enhance the reasoning capabilities of 14B-parameter models. This model is optimized for general-purpose reasoning and answering, excelling in contextual understanding, logical deduction, and multi-step problem-solving. It has been fine-tuned using a long chain-of-thought reasoning model and specialized datasets to improve comprehension, structured responses, and conversational intelligence.

Key Improvements

Enhanced General Knowledge: The model provides broad knowledge across various domains, improving capabilities in answering questions accurately and generating coherent responses.
Improved Instruction Following: Significant advancements in understanding and following complex instructions, generating structured responses, and maintaining coherence over extended interactions.
Versatile Adaptability: More resilient to diverse prompts, enhancing its ability to handle a wide range of topics and conversation styles, including open-ended and structured inquiries.
Long-Context Support: Supports up to 128K tokens for input context and can generate up to 8K tokens in a single output, making it ideal for detailed responses.

Quickstart with transformers

Here is a code snippet with apply_chat_template to show you how to load the tokenizer and model and generate content:

python

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "prithivMLmods/Cassiopeia-Qwen-14B"

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained(model_name)

prompt = "What are the key principles of general-purpose AI?"
messages = [
    {"role": "system", "content": "You are a helpful assistant capable of answering a wide range of questions."},
    {"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]

Intended Use

General-Purpose Reasoning:
Designed for broad applicability, assisting with logical reasoning, answering diverse questions, and solving general knowledge problems.
Educational and Informational Assistance:
Suitable for providing explanations, summaries, and research-based responses for students, educators, and general users.
Conversational AI and Chatbots:
Ideal for building intelligent conversational agents that require contextual understanding and dynamic response generation.
Multilingual Applications:
Supports global communication, translations, and multilingual content generation.
Structured Data Processing:
Capable of analyzing and generating structured outputs, such as tables and JSON, useful for data science and automation.
Long-Form Content Generation:
Can generate extended responses, including articles, reports, and guides, maintaining coherence over large text outputs.

Limitations

Hardware Requirements:
Requires high-memory GPUs or TPUs due to its large parameter size and long-context support.
Potential Bias in Responses:
While designed to be neutral, outputs may still reflect biases present in training data.
Inconsistent Outputs in Creative Tasks:
May produce variable results in storytelling and highly subjective topics.
Limited Real-World Awareness:
Does not have access to real-time events beyond its training cutoff.
Error Propagation in Extended Outputs:
Minor errors in early responses may affect overall coherence in long-form outputs.
Prompt Sensitivity:
The effectiveness of responses may depend on how well the input prompt is structured.
