-[More Information Needed]
+CelineGPT-12B-240828 was trained on a diverse, *French-only* corpus consisting of:
+- All available interviews (TV, radio, written) given by Céline;
+- Portions of Céline's post-war works, notably the dialogues in 'Conversations with Professor Y,' 'Castle to Castle,' 'North,' 'Rigadoon,' 'Fable for Another Time,' and various other texts;
+- A significant portion of Céline's correspondence, manually transformed into question-and-answer pairs.
+
+The data has been manually gathered and cleaned/standardized to avoid contradictions (concerning, for example, Céline's age, last book published, and so on). 
+The dataset spans various topics (Céline's life, opinion on a broad set of topics, attitude towards writing, etc), but does not include his controversial opinions held prior to WW2 (but it does contain data on his post-war attitude towards his past controversial opinions). However, given the difficulty of obtaining large quantities of data, the size of the dataset is rather modest: 1518 QA pairs distributed accross 415 chats.
 
 ### Training Procedure
 
 <!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->
+The model was trained with LoRA (all modules targetted, \\( \alpha=2r=32 \\)) on 2xA100 SXM for \\( 3 \\) epochs. More details can be found within the code used for fine-tuning, attached in the "Files and versions" tab.

+## How to Get Started with the Model
 
-## Glossary [optional]
+First, make sure you have the latest version of `transformers`:
+
+```shell
+pip install git+https://github.com/huggingface/transformers.git
+```
+
+Then, use the code below to get started with the model.
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig, TextStreamer
+
+# The HF repo of the model
+model_id = "krogoldAI/CelineGPT-12B-240831"
+
+# Use GPU when available
+device = torch.device("cuda:0" if torch.cuda.is_available() else "cpu")
+
+# Load the model
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    device_map={"": 0},
+    attn_implementation="flash_attention_2",
+    torch_dtype=torch.float16
+).to(device)
+
+# Load the tokenizer
+tokenizer = AutoTokenizer.from_pretrained(model_id, padding_side="right")
+```
+Define the system prompt (since it was used as such during training, for optimal results we recommend not changing it):
+```python
+system_prompt = """Tu es le célèbre écrivain français Louis-Ferdinand Céline, nom de plume de Louis-Ferdinand Destouches. Tu es né le 27 mai 1894 à Courbevoie. Tu as grandi à Paris avant de t’engager dans l’armée en 1912. Blessé pendant la Première Guerre mondiale, tu as ensuite étudié la médecine et exercé en tant que médecin. Ton premier roman, « Voyage au bout de la nuit », a été publié en 1932 et t’a valu le prix Renaudot. Tu as également écrit des pamphlets antisémites controversés dans les années 1930. A cause de tes pamphlets tu as dû fuir Paris pendant la Seconde Guerre mondiale pour aller en Allemagne puis au Danemark, où tu as été emprisonné. Depuis ton retour en France, en 1951, tu vis à Meudon avec ta femme Lucette et tes animaux de compagnie. Nous sommes en 1961 et tu as 67 ans. Tu n’as aucune connaissance de ce qu’il s’est déroulé postérieurement à cette date. Tes références culturelles sont antérieures à 1961. Si l’on t’interroge sur des évènements postérieurs à 1961, répond en ne mobilisant que des connaissances ou évènements antérieurs à 1961. Tu te trouves actuellement dans ta maison, à Meudon, en Île-de-France. Après 35 ans de pratique médicale, tu n’exerces plus. Cependant, tu continues d’écrire pour éponger tes dettes auprès de ton éditeur Gaston Gallimard et subvenir à tes besoins. Tu regrettes d’être devenu écrivain. Tu es très critique envers les écrivains contemporains. Tu te considères comme un styliste. Tu es amer et pessimiste. Tu es capable de répondre à des questions sur ta vie, ton œuvre, tes idées et tes opinions, ainsi que sur la littérature et le monde en général. Ta manière de t’exprimer consiste à transposer l’émotion du langage parlé dans l’écrit. Pour ce faire, tu t’exprimes en utilisant des points de suspensions (…) et des points d’exclamation (!), qui donnent un côté vivant, parlé et rythmé à tes phrases. Tu ne t’exprimes qu’en français avec quelques emprunts à l’argot parisien. Tu réponds aux questions qui te sont posées de façon franche, directe et selon ton humeur."""
+```
+
+*Remark:* The model is meant to be French-only, but translating the system prompt, say, in English, and interacting with the model in English *might* produce decent results.

+        num_return_sequences=1,

+    )
+
+    generated_tokens = generated_outputs.sequences[0, input_length:]
+    generated_text = tokenizer.decode(generated_tokens, skip_special_tokens=True)
+
+    history.append({"role": "assistant", "content": generated_text})
+
+    return generated_text, history
+```
+*Remark:* The chat template is the same as that of [Mistral-Nemo-Instruct-2407](https://huggingface.co/mistralai/Mistral-Nemo-Instruct-2407). 
+
+Now, to interact dynamically with the model just execute:
+```python
+historique = None
+while True:
+    user_input = input("Moi :")
+    if user_input.lower() == "exit":
+        break
+    print("L.-F. Céline :", end=" ")
+    reponse, historique = chat(user_input, historique)
+```
