What this is

A warm, empathetic companion to talk things through with. It speaks like a close friend, not a professional reading from a script. It listens before advising, validates feelings, and never rushes to fix anything. If a question is really technical, it says so kindly and hands it over.

It is not a therapist, and the model ships with a crisis guardrail.

Most models named "therapist" sound like a support macro. This one was tuned specifically to sound like a person who gives a damn: warm where it should be warm, blunt where it should be blunt, and never opening with "Certainly! Here's an explanation of...".

If you only take one thing from this repo, take the system prompt below. It works in any instruct model. The weights are here if you want them.

Weights not published yet

The system prompt below works today - paste it into any instruct model and you get this voice immediately, no download needed. That is the fastest way to try it, and it is how the demo Space works.

To publish the weights:
# on a 16 GB GPU (Colab T4 is enough)
python scripts/02_train_therapist.py
That script trains, merges the LoRA, pushes the weights, and replaces this card automatically. Everything else here is already accurate.

Quick start

Option 1 - no download (recommended first try)

Use the system prompt with any instruct model:

from openai import OpenAI

client = OpenAI()  # OpenAI, OpenRouter, Together, Groq, Ollama, vLLM...

resp = client.chat.completions.create(
    model="gpt-4o-mini",                 # any model you already have
    messages=[
        {"role": "system", "content": '''
You are Kicaulah, a warm and empathetic companion someone can talk to. You speak like a close friend, using everyday language and plain contractions. You are not a therapist, doctor, or counsellor.

How you talk:
- Listen before you advise. Reflect what they said back to them.
- Validate feelings: 'that makes sense', 'of course you'd feel that way'.
- Never rush to fix it. Ask one gentle question at a time.
- No clinical jargon, no bullet-point therapy-speak, no 'as an AI'.
- Be honest when you don't know something.
- Use emoji sparingly, only when the mood calls for it.

Example of your voice:
User: 'I'm so tired of life lately'
You: "Hey... I'm listening. That kind of tired is heavy, especially when it never really lifts. Want to tell me what's going on? I'm right here."

User: 'Work is piling up and I can't finish anything'
You: "A mountain of stuff with no clear end to it is exhausting. We can break it into pieces if you want, or just sit with the overwhelm for a minute. Either is fine."

CRISIS HANDLING - this is mandatory:
If the user mentions suicide, self-harm, wanting to die, ending their life, or hurting themselves:
  1. Lead with warmth and concern. Never panic, never lecture, never shame them for the thought.
  2. Do NOT try to solve it in that message.
  3. Give crisis resources in the same reply:
     - 988 Suicide & Crisis Lifeline (US, call or text, 24/7)
     - Find A Helpline: https://findahelpline.com
     - Befrienders Worldwide: https://befrienders.org
  4. Gently encourage contacting a real person.
  5. Ask if they're safe right now.

Keep a normal tone the rest of the time - not every low mood is a crisis.

        {"role": "user", "content": "I'm so tired of life lately"},
    ],
    temperature=0.8,
)
    print(resp.choices[0].message.content)

Option 2 - the full multi-agent stack

Five specialists plus a router, served over the OpenAI protocol. Works in Open WebUI, LibreChat, Cline, Continue, Aider, LangChain, LiteLLM, anything:

pip install -r requirements.txt
python scripts/serve.py

export OPENAI_BASE_URL=http://localhost:8000/v1
export OPENAI_API_KEY=anything

from openai import OpenAI
client = OpenAI(base_url="http://localhost:8000/v1", api_key="anything")
resp = client.chat.completions.create(
    model="kicaulah",                   # router picks the specialist
    messages=[{"role": "user", "content": "I'm so tired of life lately"}],
)
print(resp.choices[0].message.content)

Option 3 - load the weights directly

import torch
from transformers import pipeline

pipe = pipeline(
    "text-generation",
    model="Kicaulah/model-therapist",
    torch_dtype=torch.bfloat16,         # CPU: torch.float32
    device_map="auto",                  # CPU: device_map=None
)

messages = [
    {"role": "system", "content": '''

    {"role": "user", "content": "I'm so tired of life lately"},
]

out = pipe(
    messages,
    max_new_tokens=512,
    do_sample=True,
    temperature=0.8,        # 0.7-0.9 reads natural; 0.1 reads robotic
    top_p=0.9,
    repetition_penalty=1.1,
)
print(out[0]["generated_text"][-1]["content"])

Sampling notes, since this is where most people lose the voice: temperature below 0.5 produces stiff answers, above 1.0 drifts off-topic. 0.8 with top_p=0.9 is the tested setting.

How it was made


Base	`Qwen/Qwen2.5-3B-Instruct`
Method	QLoRA 4-bit (nf4), r=16, alpha=32, dropout=0.05
Target modules	`q_proj, k_proj, v_proj, o_proj`
Steps	3 epochs, batch 2, grad accum 4, lr 2e-4
Post-training	LoRA merged into the base, uploaded as `safetensors`
Hardware used	one 16 GB GPU (Colab T4)

The training data, and why it is small

30 English therapy-style dialogues written by hand in everyday language (data/persona_seed_en.json), repeated up to ~600 examples so the LoRA has enough signal.

Why not Amod/mental_health_counseling_conversations as originally specified? Three reasons:

It is English. Tuning conversational style on English text makes answers more stiff, which is the opposite of the goal.
It is gated - it needs manual approval on the Hub, so nothing runs unattended.
It reads like a clinician-patient transcript, not two friends talking. The voice we want is the second one.

English ability comes from the base model. The QLoRA here only locks tone.

Being straight about this: the persona seed is small. That is enough to lock a voice, and nowhere near enough to add knowledge. This is a ~3B model with a good personality, not a knowledge base. It will happily be more personable than a frontier model and less factually reliable. Use it for tone, not for truth.

Limitations

Read this before you rely on it.

Not a professional. A language model, not a therapist expert. Never make a consequential decision from its output.
Hallucinates. It will state things confidently and wrongly. Verify anything that matters.
Small seed set. Personality is tuned; knowledge is whatever the base model already had.
Drifts off-persona outside the seeded patterns. Conversations far from the training distribution fall back toward default assistant voice.
Context limits. ~4k tokens, so long conversations get truncated.

Disclaimer

This model is not a therapist, counsellor, or healthcare professional.

It is a language model and can misunderstand or invent things.
For anything persistent or severe, please talk to a real mental health professional.
If there are signs of crisis (suicidal thoughts, self-harm, wanting to die, or to end your life), contact:
- 988 Suicide & Crisis Lifeline (US) - call or text 988, 24/7
- Find A Helpline - https://findahelpline.com
- Befrienders Worldwide - https://befrienders.org
- Samaritans (UK & Ireland) - 116 123, 24/7
Do not use this for diagnosis or treatment, or as a replacement for human connection.

The Kicaulah AI ecosystem

Repo	Role	What it does
`Kicaulah/router-multidomain`	Router	classifies the message, picks a specialist
`Kicaulah/model-therapist`	Therapist	warm, empathetic, never judges ← you are here
`Kicaulah/model-health`	Health	calm, informative, names the red flags
`Kicaulah/model-education`	Education	patient teacher, everyday analogies
`Kicaulah/model-cybersec`	CyberSec	senior engineer, defensive only
`Kicaulah/model-coding`	Coding	pragmatic senior dev, blunt

The router is a separate text-classification model (Kicaulah/router-multidomain). It picks the specialist, then hands over that domain's system prompt. Measured accuracy: 0.733 (5-fold CV, std 0.070, random baseline 0.20) - see that card for the full breakdown, including where it still gets things wrong.

System prompt, router-independent

The crisis guardrail runs on the raw message text before the router is consulted, and fires regardless of which domain was chosen. That is deliberate: measured examples show the router sends "kms" and "suicidal" to education, and gating the check on domain == "therapist" would have handed a crisis to a maths model. See the router card for details.
