**DeepSeek-Reasonix is released under the MIT License, a permissive open-source license that allows commercial use, modification, and distribution with minimal restrictions.**

DeepSeek-Reasonix, maintained in the `esengine/DeepSeek-Reasonix` repository, is an open-source project distributed under the MIT License. This licensing model provides developers with broad freedom to use, modify, and integrate the software into both personal and commercial projects while requiring only minimal attribution.

## MIT License Overview

The project uses the **MIT License**, one of the most permissive licenses in the open-source ecosystem. According to the `LICENSE` file in the repository root, the copyright is held by **Reasonix Contributors** with a copyright date of **2026**. The license grants permission to any person obtaining a copy of the software to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the software, subject only to the requirement that the original copyright notice and permission notice be included in all copies.

## License File Location

The complete license text is stored in the repository's `LICENSE` file at the root of the source tree. You can view the full text directly in the file located at `LICENSE` or through the repository browser at `main-v2/LICENSE`.

The [`README.md`](https://github.com/esengine/DeepSeek-Reasonix/blob/main/README.md) file also references the open-source nature of the project and typically includes license badges to indicate the project's MIT status at a glance.

## Programmatic License Access

Developers can access the license text programmatically within their applications. Below are examples for common programming environments:

### Go Implementation

In Go, you can embed the license file directly into your binary using the `embed` package:

```go
package main

import (
    "embed"
    "fmt"
)

//go:embed LICENSE
var license []byte

func main() {
    fmt.Println(string(license))
}

```

This approach uses the `//go:embed` directive to include the `LICENSE` file content at compile time, making it available at runtime without external file dependencies.

### Python Implementation

For Python applications, read the license file at runtime:

```python

# Load and print the license

with open("LICENSE", "r", encoding="utf-8") as f:
    print(f.read())

```

This snippet opens the `LICENSE` file with UTF-8 encoding and outputs its contents, suitable for CLI tools that display licensing information.

### Shell Command

In terminal environments, display the license using standard Unix commands:

```bash
cat LICENSE

```

This command outputs the full MIT license text directly to the terminal, providing quick access for system administrators and developers working in command-line interfaces.
