Architectural Comparison

Efficiency and Scalability

• LLaMA 4: MoE architecture reduces inference costs by 70% compared to dense models. Scout processes 10M tokens at $0.19–$0.49 per million tokens, undercutting GPT-4o ($4.38/M tokens).
• DeepSeek: Achieves coding performance parity with 32B parameters against LLaMA 4’s 402B, demonstrating superior parameter efficiency.
• Gemini: Optimised for Google’s TPU infrastructure, enabling real-time responses but requiring significant cloud resources for full multimodal capabilities.
• ChatGPT: High operational costs due to dense architecture, though custom GPTs allow task-specific optimisations.

Multimodal Capabilities

• LLaMA 4 Maverick: Leads in image reasoning (MMMU score: 73.4) and document analysis (DocVQA: 94.4). Early fusion architecture integrates text, images, and video during pretraining.
• Gemini 2.5: Processes audio-visual data with low latency, ideal for real-time translation and video summarisation.
• ChatGPT: Relies on plugins for multimodal tasks, lagging in native image/video understanding.
• DeepSeek: Primarily text-focused, with limited multimodal support.

Performance Benchmarks

Model	LiveCode Bench Score	Parameters	Cost Efficiency
DeepSeek-V3-0324	76.2	32B	1.0x
Llama 4 Maverick	43.4	402B	0.3x
GPT-4.5	68.9	~1.8T	0.7x
Gemini 2.5	54.1	~340B	0.5x

DeepSeek really shines when it comes to coding. It solves 76.2% of the LiveCodeBench challenges and beats Llama 4 Maverick by 32.8 points, all while using 12.5 times fewer parameters. 

Users have found that Llama 4 has trouble with simple programming tasks, like coding a bouncing ball simulation, and often produces code that has syntax issues. 

ChatGPT and Gemini aren’t as strong in specific coding tasks, but they do provide better support for debugging with their built-in tools.

Reasoning and Knowledge

Model	MMLU Pro	MATH-500	Training Data
Llama 4 Behemoth	82.2	95.0	30T tokens
GPT-4.5	85.1	96.3	13T tokens
Gemini 2.5 Pro	80.7	89.5	15T tokens
DeepSeek-R1	78.4	91.2	8T tokens

GPT-4.5 is the go-to for general knowledge, scoring 85.1 on the MMLU Pro test. On the math side, Llama 4 Behemoth really stands out with a score of 95.0 on the MATH-500 test. 

DeepSeek has a smaller training set, which means it might not cover as much, but it does have solid technical accuracy with a 91.2 on MATH-500.

Creative Writing

• ChatGPT: Generates nuanced narratives with adjustable tone, preferred for marketing content and storytelling.
• LLaMA 4 Maverick: Produces detailed, formal prose suitable for academic writing (rated 4.8/5 by technical users).
• Gemini: Balances creativity and conciseness, ideal for social media snippets.
• DeepSeek: Lacks stylistic flexibility; often perceived as “dry” by creative professionals.

Which AI LLM Truly Stands Out in 2025?

Each AI model has its strengths, making them fit for different jobs. **DeepSeek** is great for coding and technical tasks, offering strong performance at a low price, especially useful for debugging and algorithm design. 

LLaMA 4 does well with multimodal tasks, like analysing textbooks with diagrams or medical images, and it’s good with long documents, such as legal papers. It’s also a strong choice for open-source projects where community input can make a difference.

Gemini really shines in real-time applications, like voice assistants or live translation, and it works well with multiple languages, thanks to Google’s big language databases. 

Meanwhile, ChatGPT is fantastic for creative work—think content creation, storytelling, and answering all sorts of questions, though it can be more expensive. 

So, the best AI model really depends on what you’re looking to do: DeepSeek for tech stuff, LLaMA 4 for research, Gemini for real-time needs, and ChatGPT for creative projects.
