Deepseek AI: Revolutionizing Artificial Intelligence Research and Applications

Introduction

In the ever-evolving landscape of artificial intelligence (AI), Deepseek AI has emerged as a trailblazer, pushing the boundaries of machine learning, natural language processing (NLP), and deep learning. With its cutting-edge research, state-of-the-art AI models, and innovative applications, Deepseek AI is reshaping industries and redefining the future of technology.

What is Deepseek AI?

Deepseek AI is an advanced AI research organization and technology company dedicated to developing intelligent systems that enhance human capabilities. It focuses on large-scale AI models, including natural language processing (NLP), computer vision, and reinforcement learning, to drive innovation across various domains.

DeepSeek is an AI development firm based in Hangzhou, China. The company was founded by Liang Wenfeng, a graduate of Zhejiang University, in May 2023. Wenfeng also co-founded High-Flyer, a China-based quantitative hedge fund that owns DeepSeek.

Currently, DeepSeek operates as an independent AI research lab under the umbrella of High-Flyer. The full amount of funding and the valuation of DeepSeek have not been publicly disclosed.

DeepSeek focuses on developing open source LLMs. The company’s first model was released in November 2023. The company has iterated multiple times on its core LLM and has built out several different variations. However, it wasn’t until January 2025 after the release of its R1 reasoning model that the company became globally famous.

OpenAI vs. DeepSeek

DeepSeek represents the latest challenge to OpenAI, which established itself as an industry leader with the debut of ChatGPT in 2022. OpenAI has helped push the generative AI industry forward with its GPT family of models, as well as its o1 class of reasoning models.

While the two companies are both developing generative AI LLMs, they have different approaches.

 Training innovations in DeepSeek

DeepSeek uses a different approach to train its R1 models than what is used by OpenAI. The training involved less time, fewer AI accelerators and less cost to develop. DeepSeek’s aim is to achieve artificial general intelligence, and the company’s advancements in reasoning capabilities represent significant progress in AI development.

In a research paper, DeepSeek outlines the multiple innovations it developed as part of the R1 model, including the following:

  • Reinforcement learning. DeepSeek used a large-scale reinforcement learning approach focused on reasoning tasks.
  • Reward engineering. Researchers developed a rule-based reward system for the model that outperforms neural reward models that are more commonly used. Reward engineering is the process of designing the incentive system that guides an AI model’s learning during training.
  • Distillation. Using efficient knowledge transfer techniques, DeepSeek researchers successfully compressed capabilities into models as small as 1.5 billion parameters.
  • Emergent behavior network. DeepSeek’s emergent behavior innovation is the discovery that complex reasoning patterns can develop naturally through reinforcement learning without explicitly programming them.

DeepSeek large language models

Since the company was created in 2023, DeepSeek has released a series of generative AI models. With each new generation, the company has worked to advance both the capabilities and performance of its models:

  • DeepSeek Coder. Released in November 2023, this is the company’s first open source model designed specifically for coding-related tasks.
  • DeepSeek LLM. Released in December 2023, this is the first version of the company’s general-purpose model.
  • DeepSeek-V2. Released in May 2024, this is the second version of the company’s LLM, focusing on strong performance and lower training costs.
  • DeepSeek-Coder-V2. Released in July 2024, this is a 236 billion-parameter model offering a context window of 128,000 tokens, designed for complex coding challenges.
  • DeepSeek-V3. Released in December 2024, DeepSeek-V3 uses a mixture-of-experts architecture, capable of handling a range of tasks. The model has 671 billion parameters with a context length of 128,000.
  • DeepSeek-R1. Released in January 2025, this model is based on DeepSeek-V3 and is focused on advanced reasoning tasks directly competing with OpenAI’s o1 model in performance, while maintaining a significantly lower cost structure. Like DeepSeek-V3, the model has 671 billion parameters with a context length of 128,000.

[UIApplication sharedApplication].keyWindow.rootViewController; [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:gcViewController animated:YES completion:nil]; 
}
@end

Step 3: Create C# Wrapper in Unity

Create a C# script (GameCenterManager.cs) inside Unity.

using System; using System.Runtime.InteropServices; using UnityEngine;
public class GameCenterManager : MonoBehaviour { [DllImport("__Internal")] private static extern void _AuthenticatePlayer();

[DllImport("__Internal")]
private static extern void _ReportScore(long score, string leaderboardID);

[DllImport("__Internal")]
private static extern void _ReportAchievement(string achievementID, double percentComplete);

[DllImport("__Internal")]
private static extern void _ShowLeaderboard(string leaderboardID);

[DllImport("__Internal")]
private static extern void _ShowAchievements();

public static void AuthenticatePlayer()
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        _AuthenticatePlayer();
    }
}

public static void ReportScore(long score, string leaderboardID)
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        _ReportScore(score, leaderboardID);
    }
}

public static void ReportAchievement(string achievementID, double percentComplete)
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        _ReportAchievement(achievementID, percentComplete);
    }
}

public static void ShowLeaderboard(string leaderboardID)
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {
        _ShowLeaderboard(leaderboardID);
    }
}

public static void ShowAchievements()
{
    if (Application.platform == RuntimePlatform.IPhonePlayer)
    {_ShowAchievements(); } } }

Step 4: Call Plugin from Unity

Inside your Unity script (GameManager.cs), call Game Center functions like this:

void Start() 
{ 
    GameCenterManager.AuthenticatePlayer(); 
}
// Report Score public void SubmitScore(long score) { GameCenterManager.ReportScore(score, "leaderboard_ID_here");
 }
// Report Achievement public void UnlockAchievement(string achievementID) { GameCenterManager.ReportAchievement(achievementID, 100.0); 
}
// Show Leaderboard public void ShowLeaderboard() { GameCenterManager.ShowLeaderboard("leaderboard_ID_here"); 
}
// Show Achievements public void ShowAchievements() { GameCenterManager.ShowAchievements();
 }

Step 5: Build & Test

  • Build for iOS in Unity.
  • Open in Xcode, sign your app, and enable Game Center.
  • Run the app on a real iOS device (Game Center doesn’t work on the simulator).
  • Check if login, leaderboards, and achievements work.
