# NPC Model
This repo contains the domain-specific NPC model we've fined-tuned from **Phi-3-128k**, using LoRA.
This model parses a text description of a game scene, and outputs commands like:
* `say <player1> "Hello Adventurer, care to join me on a quest?`
* `greet <player1>`
* `attack <player1>`
* Any other `<action> <param>` you add to the prompt! (We call these "skills"!)
⚠️ This model has been trained to **overfit** on our input prompt format. Follow it closely to reach optimal performance ⚠️
## Usage
**Make your life easier, use our [Python client library](https://github.com/GigaxGames/gigax)**
* Instantiating the model using outlines:
```py
from outlines import models
from gigax.step import NPCStepper
from llama_cpp import Llama
# Download model from the Hugging Face Gigax Hub before run this code
# Our stepper takes in a Outlines model to enable guided generation
# This forces the model to follow our output format
llm = Llama.from_pretrained(
repo_id="Gigax/NPC-LLM-3_8B-128k-GGUF",
filename="npc-llm-3_8B-128k.gguf"
# n_gpu_layers=-1, # Uncomment to use GPU acceleration
# seed=1337, # Uncomment to set a specific seed
# n_ctx=2048, # Uncomment to increase the context window
)
model = models.LlamaCpp(llm)
# Instantiate a stepper: handles prompting + output parsing
stepper = NPCStepper(model=model)
```
* Calling the model on your game's data:
```py
from gigax.parse import CharacterAction
from gigax.scene import (
Character,
Item,
Location,
ProtagonistCharacter,
ProtagonistCharacter,
Skill,
ParameterType,
)
# Use sample data
context = "Medieval world"
current_location = Location(name="Old Town", description="A quiet and peaceful town.")
locations = [current_location] # you can add more locations to the scene
NPCs = [
Character(
name="John the Brave",
description="A fearless warrior",
current_location=current_location,
)
]
protagonist = ProtagonistCharacter(
name="Aldren",
description="Brave and curious",
current_location=current_location,
memories=["Saved the village", "Lost a friend"],
quests=["Find the ancient artifact", "Defeat the evil warlock"],
skills=[
Skill(
name="Attack",
description="Deliver a powerful blow",
parameter_types=[ParameterType.character],
)
],
psychological_profile="Determined and compassionate",
)
items = [Item(name="Sword", description="A sharp blade")]
events = [
CharacterAction(
command="Say",
protagonist=protagonist,
parameters=[items[0], "What a fine sword!"],
)
]
action = stepper.get_action(
context=context,
locations=locations,
NPCs=NPCs,
protagonist=protagonist,
items=items,
events=events,
)
```
## Input prompt
Here's a sample input prompt, showing you the format on which the model has been trained:
```txt
- WORLD KNOWLEDGE: A vast open world full of mystery and adventure.
- KNOWN LOCATIONS: Old Town
- NPCS: John the Brave
- CURRENT LOCATION: Old Town: A quiet and peaceful town.
- CURRENT LOCATION ITEMS: Sword
- LAST EVENTS:
Aldren: Say Sword What a fine sword!
- PROTAGONIST NAME: Aldren
- PROTAGONIST PSYCHOLOGICAL PROFILE: Brave and curious
- PROTAGONIST MEMORIES:
Saved the village
Lost a friend
- PROTAGONIST PENDING QUESTS:
Find the ancient artifact
Defeat the evil warlock
- PROTAGONIST ALLOWED ACTIONS:
Attack <character> : Deliver a powerful blow
Aldren:
```
