# Spark-X2.5-4B

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

A compact 4.1B general-purpose language model with a native 1M-token context, over 200 languages and a hybrid attention design, tuned for coding and agent use. For developers who want a small open model.

Spark-X2.5-4B is a kit in the Developer category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself.

Made by XHToken

## About

### What it is

Spark-X2.5-4B is a compact general-purpose language model from XHToken, with about 4.1B parameters, post-trained from Spark-X2.5-4B-Base. It covers coding, tool use, translation, writing, reasoning and chat in more than 200 languages, and it supports a native context window of up to 1M tokens. A 1.7B sibling exists in the same family.

### Who it suits

It suits developers who want a small open model behind a coding agent or a chat tool. It also suits teams who need long documents or many languages from a small model that is lighter to host.

| Industry | Who uses it | How they use it | Example |
| --- | --- | --- | --- |
| Software | Developers | Run it behind an agent tool such as Codex | Ask it to write and explain a function |
| Global business | Localization teams | Translate and draft text across many languages | Turn a product note into several languages |
| Research | ML engineers | Test long-context behavior | Feed it a long document and ask questions |

Anyone who needs the largest possible model can skip it, since this one is built to be small.

### Where to use it

- Python with Transformers, in the format the card describes
- Inference tools the card lists as compatible, such as vLLM, SGLang, llama.cpp and MLX
- Desktop and local runners the card names, such as Ollama and LM Studio
- Agent tools the card names, such as Codex and Claude Code

| Use case | Who | What they get back |
| --- | --- | --- |
| Coding help | Developers | Code and explanations from a small local model |
| Translation | Localization teams | Text in another language |
| Long documents | Analysts | Answers over a context of up to 1M tokens |

### How to set it up

- Python with pip, for the download
- Memory for about 8.2 GB in BF16, or about 2.1 GB at 4-bit as an estimate
- One tool that loads the model, such as Transformers or a compatible runner

1. Install the Hugging Face hub client.
2. Download the model's files.
3. Load them in your chosen tool.

```sh
pip install -U huggingface_hub
hf download XHToken/Spark-X2.5-4B
```

### How to use it

The card's run steps are cut off here, so check it for the recommended settings. Load the model in Transformers, or point a compatible runner at the files, then send it a prompt. Other people's quantized versions exist, which suit tools that need smaller files.

| Tool | What it does |
| --- | --- |
| Transformers | Loads the post-trained weights in Hugging Face format |
| vLLM and SGLang | Inference frameworks the card lists as compatible |
| llama.cpp and MLX | Compatible frameworks for running on local machines |
| Ollama and LM Studio | Platforms for quick deployment |
| LLaMA-Factory | A fine-tuning framework for customizing the model |

### Example

You load Spark-X2.5-4B in Transformers and ask it to write a small function and explain it. The card's visible text shows no sample output, so judge the answer on your own task.

### For newcomers and experts

A 4B model is small, so it is a good first model to try on a modest machine. Start with the BF16 weights or a quantized copy, then test it on your own prompts.

For every three sliding-window layers it uses one full-attention layer. The card says this keeps cache size and compute low while still allowing contexts up to 1M tokens. It was trained on Huawei Ascend clusters, with large-scale reinforcement learning and post-training steps such as MOPD.

A prompt, code or tool context goes in → Hybrid attention layers read it → The 4.1B model reasons and writes → Text, code or agent steps come out

Weights size in gigabytes

| Label | Value |
| --- | --- |
| In BF16 | 8.2 GB |
| At 4-bit, estimated | 2.1 GB |

### Good to know

- Size: 4.1B parameters, about 8.2 GB in BF16 or about 2.1 GB at 4-bit as an estimate
- Context: up to 1M tokens natively, per the card
- Claims: the card says it leads open models of its size, but the visible text gives no scores
- Languages: more than 200
- License: Apache 2.0
- Cost to run: none named
- Data it reaches: the prompts you send, on your own hardware, while the download steps fetch files from the web
- Not for: nothing named in the card
