Chatbots utilizing different large language models (LLMs) for various language tasks, such as refining research questions, checking grammar, polishing language, and translation, or even enhanced information search.
PolyU ITS offers a variety of GenAI chatbots for staff and students to use in teaching, research, and work-related activities. Access requires authentication with a PolyU NetID. For technical issues of this service, please contact ITS.
The following compares these available GenAI large language models (LLMs), which can be used for multiple purposes in research.
PolyU students and staff have 1850 credits per month to use across various LLMs and image generation tools.
The first table compares the 4o series, O1 series, and DeepSeek, which all consume credits.

The CLEAR Framework provides a simple approach to improve interactions with general generative models (e.g. GPT-4o), ideal for beginners to follow and refine prompts.
Component | Description | Purpose | Example | |
---|---|---|---|---|
1 | Concise | Brevity and clarity in prompts | Remove superfluous information and allow the LLM to focus | ✅Explain the process of photosynthesis and its significance. 🚫Can you provide me with a detailed explanation of the process of photosynthesis and its significance? |
2 | Logical | Structured and coherent prompts | Help the LLM to comprehend the context and relationships between concepts | ✅List the steps to write a research paper, beginning with selecting a topic and ending with proofreading the final draft. 🚫Can you explain how to write a research paper? Like, start by doing an outline, and don’t forget to proofread everything after you finish the conclusion. Maybe add some quotes from experts in the middle, but I’m not sure where. |
3 | Explicit | Clear output specifications | Enable the LLM to provide desired output format, content, or scope | ✅Identify five renewable energy sources and explain how each works. 🚫What are some renewable energy sources? |
The 4th and 5th components of the CLEAR Framework can help you to further enhance your prompts continuously.

As LLMs evolve into specialized tools, such as Retrieval-Augmented Generation (RAG) systems and reasoning models, no single prompting strategy applies universally. Using these effectively requires understanding each chatbot's capabilities and limitations. Critical thinking is key to guiding AI toward desired outputs.
By recognizing chatbot types, we can better tailor prompts to leverage their strengths. Below, we compare three LLM chatbot categories available to PolyU researchers, with tips to maximize their potential:
