ChatML template does not work properly
The models hallucinates a lot. I am using the GGUF model and ML Studio, selected the ChatML prompt template based on Model Card
@WasamiKirua not sure about the quality of the quantized versions, I'd recommend that you load the model weights in bfloat16.
Here's a colab notebook with a chat interface, you can use this to interact with the chat model.
you are using chatml , use phi-2 template for chatting , the author mentioned that in the original model model card, https://huggingface.co./nvidia/Mistral-NeMo-Minitron-8B-Base/discussions/5#66cbf507ed5c5babdef42cd1
if you use the wrong chat template with gguf , the model hallucinates
Yeah, have to use the chat template supported by the model's tokenizer. In this case, it's chatml. It's the same template as in the model card.

Also make sure of the gguf you are using , lower quants tend to hallucinate alot , also set the temp and top p and top k to the right amounts
The SFT dataset only contained English instructions, can you try English prompts? This looks like Italian.
with English text is fine. The Minitron is a multilanguage, I dunno how much is the italian data in % but based on my experience the Mistral Nemo is able to generate Italian text pretty well. Perhaps, since you fine tuned it with Openhermes it is all about "catastrophic forget" ? but I am pretty sure OpenHermes has also Italian text. No idea honestly. Anyway did you use axolotl to fine tune ? if yes might I ask you the configuration yaml ?
The chat model is still able to generate Italian text. Catastrophic forgetting mainly occurs when you use full parameter finetuning. Since I used LoRA, there's little chance of that happening.
Here's an example:
Instruction: "Quali sono le destinazioni turistiche più apprezzate in Italia?"
Response: "Le destinazioni turistiche più apprezzate in Italia dipendono da una varietà di fattori, tra cui la storia, la cultura, la natura e la gastronomia. Alcune delle destinazioni turistiche più popolari in Italia includono: Roma, con la sua ricca storia e monumenti antichi; Venezia, famosa per le sue gondole e canali; Firenze, con il suo patrimonio artistico rinascimentale; Milano, con la sua architettura moderna e la moda; Napoli, con la sua storia e la sua cucina; e la Costa Amalfitana, con le sue spettacolari viste panoramiche. Ci sono anche molte altre destinazioni turistiche popolari in Italia, come Pompei, la Sardegna, la Sicilia, il Piemonte, la Toscana e la Liguria. In ogni regione di Italia, ci sono molte destinazioni turistiche uniche e interessanti da scoprire."
Same for me sadly, using imatrix quants, q6, the model always responds off the mark, it's being very dumb especially in E/RP...
Hi @Varkoyote , can you try the same prompts with the unquantized bfloat16 version?
Here's a colab notebook with a chat interface.
