DeepSeek
DeepSeek – Image Source: GitHub
Founded in 2023 by Liang Wenfeng, DeepSeek has rapidly emerged as a formidable challenger in the Gen AI models comparison arena.
This Chinese AI firm has disrupted the industry with its low-cost, open-source large language models that directly compete with established players like OpenAI and Anthropic.
DeepSeek Key Features
DeepSeek’s most notable innovation is its Mixture of Experts (MoE) architecture. The flagship DeepSeek-R1 model contains a massive 671 billion parameters, yet only activates 37 billion per forward pass. This selective activation significantly reduces computational requirements while maintaining high performance levels.
The model boasts an impressive 128,000 token context window, enabling analysis of extensive documents in a single session. DeepSeek-R1 can generate up to 32,000 tokens at once, making it ideal for complex reasoning tasks requiring extended outputs.
DeepSeek implements advanced reinforcement learning techniques focused specifically on reasoning tasks. Rather than using neural reward models, researchers developed a rule-based reward system that guides the AI’s learning more effectively.
This approach has yielded strong performance on mathematical competitions, achieving approximately 79.8% pass@1 on the American Invitational Mathematics Examination and 97.3% pass@1 on the MATH-500 dataset.

In coding challenges, DeepSeek has achieved a 2,029 Elo rating on Codeforces-like scenarios, compared to o1s 2,061, outperforming 96.3% of human participants in the competition.
Notably, DeepSeek was developed for under $6 million, a fraction of the estimated $100 million for OpenAI’s GPT-4. This cost efficiency extends to inference costs as well—DeepSeek R1 runs at approximately 15-50% of the cost of OpenAI’s o1 model.
In contrast to many competitors’ closed systems, DeepSeek’s open-source approach democratizes access to advanced AI capabilities. The company provides the full models, code, and evaluation prompts for public use, enabling customization and innovation.
DeepSeek offers a tiered pricing structure centered around token usage:
Model
Input (Cache Hit)
Input (Cache Miss)
Output
DeepSeek-Chat (V3)
$0.07 per 1M tokens
$0.27 per 1M tokens
$1.10 per 1M tokens
DeepSeek-Reasoner (R1)
$0.14 per 1M tokens
$0.55 per 1M tokens
$2.19 per 1M tokens
This pricing represents significant savings compared to competitors like OpenAI’s GPT-4o, which charges $1.25-$2.50 per million input tokens and $10.00 per million output tokens.
Interestingly, DeepSeek’s web interface and mobile app remain completely free to use, with no subscription fees or daily usage limits. This contrasts sharply with the subscription models of other top Gen AI models.
Grok

Elon Musk’s xAI introduced Grok as a direct challenger to established top Gen AI models, positioning it as a “truth-seeking AI companion” with distinct personality traits.
Trained on xAI’s Colossus supercluster with 10x the computing power of previous state-of-the-art models, Grok 3 represents the company’s most advanced offering to date, displaying significant improvements across reasoning, mathematics, coding, and instruction-following tasks.
Grok Key Features
At the core of Grok’s capabilities is its reasoning system, refined through unprecedented scale reinforcement learning.
The model’s Think mode enables it to spend anywhere from seconds to minutes on complex problems, mimicking human problem-solving by considering multiple approaches, verifying solutions, and evaluating requirements
Grok Thinking Harder – Image Source: xAI
This reasoning process remains completely transparent, allowing users to inspect not only the final answer but the model’s entire thought process.
Grok distinguishes itself through real-time information access, connecting directly to the web and X platform (formerly Twitter) for up-to-date knowledge. This integration provides what Musk calls a “massive advantage over other models” by enabling access to current events and trends.
The latest version introduces DeepSearch, an AI agent that summarizes key information and reasons about conflicting opinions when answering questions.
Grok Think and Reasoning Modes – Image Source: Grok
Together with Think mode, these features form a comprehensive knowledge processing system that extends far beyond simple query-response interactions.
For multimedia processing, Grok offers:
Multimodal understanding through Grok Vision on mobile devices
Image generation capabilities
Real-time audio processing in Voice Mode
Grok Strengths
Grok demonstrates exceptional performance across academic benchmarks, achieving 93.3% accuracy on the 2025 American Invitational Mathematics Examination (AIME) when using its highest level of test-time compute. This places it ahead of competitors like DeepSeek, Gemini, and GPT models on mathematical reasoning tasks.
Grok’s Performance – Image Source: xAI
The model reaches 84.6% on graduate-level expert reasoning (GPQA) and 79.4% on LiveCodeBench for code generation. Even the more efficient Grok 3 mini achieves impressive results, scoring 95.8% on AIME 2024 and 80.4% on LiveCodeBench.
Beyond benchmark performance, Grok’s willingness to answer “spicy” questions typically rejected by other AI systems gives it a distinctive character. Unlike more restricted models, Grok often says “yes” to controversial queries, though this openness raises ethical concerns about potential misuse.
