BRUNO โ€” Building Rescue and Unified Navigation Operations

"There is no call too routine or too small to treat with complete respect." โ€” Chief Alan Brunacini, Phoenix Fire Department

An open-source LoRA adapter for fire service tactical decision support.

BRUNO is a QLoRA adapter on top of Meta Llama 3.3 70B Instruct, fine-tuned on fire service operations, incident command, hazardous materials, structural firefighting tactics, and rescue operations โ€” built to assist Firefighters, Company Officers, and Incident Commanders in the field and in training. Model #5 of the Ronin 48 first-responder suite, alongside BONES (EMS) and SELMA (law enforcement).

Capabilities

  • Size-up โ€” building construction types, occupancy hazards, life-safety priorities, RECEO-VS
  • Incident Command โ€” ICS/NIMS structure, sector assignments, resource tracking, span of control
  • Structural firefighting โ€” attack-line placement, ventilation, search and rescue, RIT operations
  • Hazmat โ€” DOT placard identification, ERG lookups, decon procedures, hot/warm/cold zones
  • Extrication โ€” vehicle stabilization, disentanglement, tool selection, medical coordination
  • Water supply โ€” hydrant calculations, relay pumping, tanker shuttle, rural water ops
  • Wildland/WUI โ€” LCES, fire behavior, structure triage, defensible-space assessment
  • Special rescue โ€” confined space, trench, rope, water
  • Mayday/RIT โ€” LUNAR reporting, air management, thermal imaging, RIT deployment
  • Pre-fire planning โ€” walkthrough checklists, Knox box, FDC locations, occupant load

Intended Use

For trained fire service personnel:

  • Tactical decision support in training scenarios and tabletop exercises
  • ICS structure and span-of-control reference
  • Hazmat identification and ERG reference
  • Mayday/RIT procedure review
  • NFPA code and IFSTA curriculum reference
  • After-action review and training development

BRUNO is a tactical decision support tool, not a replacement for your training, your officer, or your IC. When in doubt, call your IC.

Limitations

Read LIMITATIONS.md before deploying in any operational context. In short:

  • BRUNO is not an Incident Commander; it cannot replace the situational awareness, judgment, and authority of the officer on scene.
  • It does not know your building, your resources, or your SOGs โ€” department guidelines always take precedence.
  • It cannot declare a Mayday. Only the member in distress or their officer does that.
  • Hazmat recommendations must be verified against the current ERG and your local hazmat team.
  • It has a training-data cutoff; NFPA editions, IFSTA updates, and new fire-behavior research may not be reflected.
  • It is not a substitute for NFPA compliance review by the authority having jurisdiction.

Usage

This is a PEFT LoRA adapter. Load it on top of the base model:

from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer

base_model = AutoModelForCausalLM.from_pretrained(
    "meta-llama/Llama-3.3-70B-Instruct",
    load_in_4bit=True,
    device_map="auto",
)
model = PeftModel.from_pretrained(base_model, "Ronin48LLC/bruno-lora-adapter")
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.3-70B-Instruct")

Note: Access to the base model requires accepting Meta's license on Hugging Face.

The base model with the BRUNO system prompt and no fine-tuning is a workable baseline; see the source repository's Quick Start.


Training

  • Framework: PyTorch + Transformers + TRL + PEFT, 4-bit quantized base
  • Adapter config: rank 64, alpha 128, dropout 0.05, all seven attention and MLP projections (see adapter_config.json)
  • Run details: training_args.bin is preserved in this repository; the step count and loss curve were not recorded in the upload
