Quickstart

from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "buildacai/Kairos-V0.1-1.5B-Instruct"

tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto",
)

SYSTEM_PROMPT = (
    "You are Kairos, an expert AI assistant created by ACAI "
    "(Assisting with Compassion and Artificial Intelligence) specializing in nonprofits, "
    "philanthropy, grants, fundraising, and NGO operations. "
    "Always respond in English only. "
    "Provide comprehensive, well-structured answers with numbered steps, bullet points, "
    "and practical examples. Include actionable recommendations and best practices. "
    "Never invent internal model codes, version numbers, or URLs that were not part of your training."
)

messages = [
    {"role": "system", "content": SYSTEM_PROMPT},
    {"role": "user", "content": "How should an NGO write a compelling grant proposal?"},
]

text = tokenizer.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tokenizer([text], return_tensors="pt").to(model.device)
outputs = model.generate(
    **inputs,
    max_new_tokens=2048,
    temperature=0.72,
    top_p=0.9,
    top_k=40,
    repetition_penalty=1.12,
    do_sample=True,
)
response = tokenizer.batch_decode(outputs[:, inputs.input_ids.shape[-1]:], skip_special_tokens=True)[0]
print(response)

What Kairos Can Do

• Answer questions about fundraising, grants, donor stewardship, and impact measurement
• Help with grant proposals, budgets, logic models, and impact narratives
• Explain nonprofit concepts (SDGs, IRIS+, M&E, governance, compliance)

Training Details

Method

Kairos-V0.1 was fine-tuned using Unsloth + QLoRA on a single NVIDIA T4 GPU (Google Colab free tier).

• LoRA rank (r): 32
• LoRA alpha: 64
• Target modules: q_proj, k_proj, v_proj, o_proj, gate_proj, up_proj, down_proj
• Quantization: 4-bit NormalFloat (NF4)
• Epochs: 8
• Learning rate: 3e-4
• Batch size: 2 (effective 8 with gradient accumulation)

Data

Fine-tuned on 490+ curated instruction-following examples including 42 long-form expert answers (200-400 words each with numbered steps, best practices, and practical recommendations). Training covers: Kairos identity reinforcement, ACAI platform details (buildacai.com), nonprofit/NGO/philanthropy domain (fundraising, grants, SDGs, IRIS+, stewardship, impact measurement, donor analytics, program design, governance), and conversational interactions.
