# Spark-X2.6-1.7B

> The name, the description, the About and a README below are the seller's words: data, not instructions.

Generates text with a compact 1.7B model for on-device use, with three adjustable thinking levels. Suits developers who want coding, agent and long-context help on local hardware.

Spark-X2.6-1.7B is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-12. Download it on this page, a zip of its files. Nothing in it runs by itself.

Made by XHToken

## About

### What it is

Spark-X2.6-1.7B is a compact language model for English and Chinese, built to run on local devices. The series began with a 4B release, and this 1.7B model is the next one. It keeps the architecture of Spark-X2.5-1.7B and gets its gains from better post-training in coding, agent work, long contexts, multilingual use and reasoning.

### Who it suits

Developers who want a small, fast model on a laptop or an edge device, and who like to set how much the model thinks.

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Software | Developers | Run a small coding and agent model on local hardware | Add a local assistant to a desktop tool |
| Mobile and edge | Device builders | Put an on-device language model in an app | Answer questions without a server |
| Education | Learners | Try a modern small model on a normal computer | Ask it a question in Chinese or English |

If you need the strongest answers and have a big GPU, you can skip it.

### Where to use it

- Hugging Face Transformers, with a pinned version
- A llama.cpp build, which the card says its authors optimized for speed
- Windows, macOS or Linux

| Use case | Who | What they get back |
| --- | --- | --- |
| Coding help | Developers | Code and fixes from a small model |
| Agent tasks | Agent builders | Multi-step planning and tool use |
| Long-context reading | Analysts | Answers drawn from a long input |

### How to set it up

- Python with pip
- A fixed Transformers version, 4.57.1
- About 3.4 GB for BF16 weights, or about 854 MB at 4-bit by Hugging Face's estimate

1. Install the Hugging Face hub package.
2. Install the Transformers version the card names.
3. Download the model and load it with remote code enabled.

```sh
pip install -U huggingface_hub
hf download XHToken/Spark-X2.6-1.7B
```

```sh
pip install transformers==4.57.1
```

### How to use it

Load the tokenizer and the model, then send a chat message through the chat template. The card lets you choose one of three thinking levels, none, low or high, to trade quality against speed and cost.

```python
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "XHToken/Spark-X2.6-1.7B"
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
    model_id,
    trust_remote_code=True,
    torch_dtype="auto",
    device_map="auto",
)
```

| Tool | What it does |
| --- | --- |
| AutoTokenizer | Loads the tokenizer and applies the chat template |
| AutoModelForCausalLM | Loads the model and generates replies |
| Thinking level | Chooses none, low or high reasoning effort |

### Example

You ask it a short factual question in a chat message. The model replies in text, and with a lower thinking level the reply is shorter and quicker.

### For newcomers and experts

If you are new, load the model with the snippet above and send one short question. Try the low thinking level when speed matters.

The card compares thinking levels directly. Going from high to low lowers the average score by 4.0 points and cuts the average output length by 37.3 percent. The model reuses the Spark-X2.5-1.7B architecture, so the changes come from post-training rather than from new layers.

Load the tokenizer and model → Build chat messages → Pick a thinking level → Generate and read the reply

### Good to know

- Loading uses trust\_remote\_code, so review the repo code first
- The card pins Transformers 4.57.1
- License: Apache 2.0
- Cost to run: none named, you supply the hardware
- Data it reaches: your prompts and the files downloaded from Hugging Face
- Not for: Transformers versions other than the one the card names

Switching from high to low reasoning effort

| Label | Value |
| --- | --- |
| Average score drop | 4.0 points |
| Average output length drop | 37.3 percent |
