Suffix meaning IT vs PT
Hi guys
What are the meanings (difference) in model suffixes as (it vs pt) e.g. google/gemma-3-27b-it
Thank you
it is the instruction tuned version, and pt is the pretrained version or the base model, which will not follow instructions.
Thank you. Got it. Are instructions the same or related to tools
Hi @jvoid , The Gemma model was released in two main variants: a pre-trained model and an instruction-tuned model with it's different weight sizes. Pre-trained models are also known as base models and do not have the 'it' suffix with it's name("google/gemma-2-27b"). Whereas Instruction-tuned models will have the 'it' suffix with it's name("google/gemma-2-27b-it").
The difference between Pre-trained models(base) and Instruction tuned models(it):
Pre-trained models are general purpose models, trained on large amount of data and can be adapted to various tasks. But these models will have different performance or output quality for the specific tasks. Where it comes to use the instruction tuned models - Instruction tuned models are trained to follow the instructions and generate more quality text. Instruction tuned models can be fine-tuned with domain-specific data for specific use-cases to have better performance with required features and good output quality.
If you have any concerns let us know will assist you. Thank you.
Hi
@lkv
. Thank you for clarification.
Could please dive a little in details what does the term instruction mean here. Is it something related to mcp tools. Or are tools kind of subset of instruction term.
Thank you
@jvoid , Instruction is a command given to a Large Language Model (LLM) that tells it what to do with a piece of information. Instruction fine-tuning is the training process that teaches a base model to follow these commands effectively and act as a helpful assistant. and Regarding "mcp tools," that might be a specific term for a framework you're using. I hope you got the clarification, let me you know if you have any concerns. Thank you.
