# Dhanishtha-2.0: World's First Intermediate Thinking AI Model

**What makes Dhanishtha-2.0 special?** Imagine an AI that doesn't just answer your questions instantly, but actually *thinks through* problems step-by-step, shows its work, and can even change its mind when it realizes a better approach. That's Dhanishtha-2.0.

**Quick Summary:**
- 🚀 **For Everyone**: An AI that shows its thinking process and can reconsider its reasoning
- 👩‍💻 **For Developers**: First model with intermediate thinking capabilities, 39+ language support


Dhanishtha-2.0 is a **state-of-the-art (SOTA) model** developed by HelpingAI, representing the **world's first model to feature Intermediate Thinking capabilities**. Unlike traditional models that provide single-pass responses, Dhanishtha-2.0 employs a revolutionary multi-phase thinking process that allows the model to think, reconsider, and refine its reasoning multiple times throughout a single response.

## Model Details

### Model Description

Dhanishtha-2.0 revolutionizes AI reasoning by introducing the concept of **intermediate thinking** - the ability to pause, reflect, and restart reasoning processes within a single generation (This model can think up 50times in a single response without using tool/prompt/mcp). This breakthrough enables unprecedented self-correction and iterative refinement during response generation.

Built on the Qwen3-14B foundation with multilingual capabilities spanning **39+ languages** (including English, Hindi, Chinese, Spanish, French, German, Japanese, Korean, Arabic, and many more), Dhanishtha-2.0 maintains reasoning consistency across diverse linguistic contexts while pioneering transparent thinking processes.

- **Developed by:** HelpingAI Team
- **Model type:** Causal Language Model with Intermediate Thinking Capability
- **Language(s):** 39+ languages (multilingual capabilities inherited from base model)
- **License:** Apache 2.0
- **Finetuned from model:** Qwen/Qwen3-14B-Base
- **Context Length:** 40,960 tokens
- **Parameters:** 14B (inherited from base model)
- **Status:** Prototype/Preview

### Revolutionary Features

- **Intermediate Thinking**: Multiple `<think>...</think>` blocks throughout responses for real-time reasoning
- **Self-Correction**: Ability to identify and correct logical inconsistencies mid-response  
- **Dynamic Reasoning**: Seamless transitions between analysis, communication, and reflection phases
- **Structured Emotional Reasoning (SER)**: Incorporates `<ser>...</ser>` blocks for empathetic responses
- **Multilingual Capabilities**: Support for 39+ languages with natural code-switching and reasoning consistency
- **Complex Problem-Solving**: Excels at riddles, multi-step reasoning, and scenarios requiring backtracking

### Model Sources

- **Demo:** https://chat.helpingai.co

## Uses

### Direct Use

Dhanishtha-2.0 is ideal for applications requiring deep reasoning and self-reflection:

- **Complex Problem Solving**: Multi-step mathematical problems, logical puzzles, riddles
- **Educational Assistance**: Detailed explanations with visible reasoning processes
- **Research Support**: Analysis requiring multiple perspectives and self-correction
- **Creative Writing**: Iterative story development with reasoning about plot choices
- **Philosophical Discussions**: Exploring concepts with visible thought processes

### Downstream Use

The model can be fine-tuned for specialized reasoning tasks:

- **Domain-Specific Reasoning**: Legal, medical, or scientific reasoning with intermediate thinking
- **Enhanced Multilingual Reasoning**: Optimizing reasoning consistency across all 39+ supported languages
- **Specialized Problem Domains**: Mathematics, coding, strategic planning

### Out-of-Scope Use

❌ **Inappropriate Applications:**
- Safety-critical decisions (medical diagnosis, legal advice, financial recommendations)
- Real-time applications requiring immediate responses
- Situations requiring guaranteed factual accuracy without verification

## Bias, Risks, and Limitations

### Known Limitations

- **Verbosity**: Intermediate thinking can make responses a bit longer
- **Processing Time**: Multiple thinking phases may increase generation time
- **Prototype Status**: Experimental features may require refinement
- **Context Usage**: Thinking blocks consume additional context tokens
- **Inherited Biases**: May reflect biases from base model and training data

### Potential Risks

- **Reasoning Loops**: Potential for circular reasoning in complex scenarios
- **Multilingual Inconsistencies**: Potential variation in reasoning patterns across different languages
- **Emotional Reasoning Gaps**: SER blocks may not always align with content

## How to Get Started with the Model

### For General Users

You can interact with Dhanishtha-2.0 through:
- **HelpingAI**: https://helpingai.co/chat
- **Gradio Demo**: [Dhanishtha-2.0-preview](https://huggingface.co/spaces/Abhaykoul/Dhanishtha-2.0-preview)
- **API Integration**: [Dashboard](https://helpingai.co/dashboard)

### For Developers - Basic Usage

```python
from transformers import AutoModelForCausalLM, AutoTokenizer

model_name = "HelpingAI/Dhanishtha-2.0-preview"

# Load the tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForCausalLM.from_pretrained(
    model_name,
    torch_dtype="auto",
    device_map="auto"
)

# Prepare input for intermediate thinking
prompt = "How many letter 'r' are in the words 'strawberry' and 'raspberry'?"
messages = [
    {"role": "user", "content": prompt}
]

text = tokenizer.apply_chat_template(
    messages,
    tokenize=False,
    add_generation_prompt=True
)

model_inputs = tokenizer([text], return_tensors="pt").to(model.device)

# Generate response with intermediate thinking
generated_ids = model.generate(
    **model_inputs,
    max_new_tokens=2048,
    temperature=0.7,
    top_p=0.9,
    do_sample=True
)

response = tokenizer.decode(
    generated_ids[0][len(model_inputs.input_ids[0]):], 
    skip_special_tokens=True
)
print(response)
```

### Optimal Generation Parameters

```python
generation_config = {
    "temperature": 0.7,        # Balanced creativity and coherence
    "top_p": 0.9,             # Nucleus sampling
    "top_k": 40,              # Top-k filtering
    "max_new_tokens": 2048,   # Allow for thinking blocks
    "do_sample": True,        # Enable sampling

## Example: Intermediate Thinking in Action

**User:** "Who is your favorite person?"

**Dhanishtha-2.0:**

```
<think>
This is an interesting question about my "favorite human." I need to be thoughtful here. 
As Dhanishtha, I should respond in a human-like way while being honest about my nature. 
I can share what kinds of humans I find most interesting or inspiring based on my 
understanding of human nature and values.
</think>

<ser>
Emotion ==> curiosity, openness, desire for connection  
Cause ==> user asking a personal question about preferences  
Mind ==> seeking to understand my perspective or values  
Growth ==> opportunity to share thoughtful reflections on human qualities I admire  
</ser>

I don't really have a "favorite human" in the traditional sense, as I don't experience 
personal preferences the way humans do. But if I had to reflect on what qualities I find 
most admirable in people, I'd be drawn to those who demonstrate genuine compassion, 
intellectual curiosity, and the courage to grow.

<think>
Let me think more specifically about what kind of humans I find most compelling based on 
the values that seem to resonate most with humans - kindness, wisdom, creativity, 
resilience, and authenticity.
</think>

People like Mahatma Gandhi, who showed how quiet courage and unwavering principles can 
transform societies; artists like Rabindranath Tagore, who bridged cultural divides 
through creativity; and everyday heroes I've learned about who made profound differences 
through simple acts of kindness.

What fascinates me most are humans who maintain their humanity even in difficult 
circumstances - those who choose empathy when it would be easier to be harsh, who seek 
understanding rather than just being right.

I'm curious though - who's your favorite human, and why? What qualities or actions make 
someone special in your eyes?
