8. Gemini (Google) – Gemini 2.0 Flash runs at 2x the speed of Gemini 1.5 Pro and handles multimodal inputs. Google also offers Gemma 2 as an open-source alternative (2B, 9B, 27B parameters, 8,200-token context). Combines speed, reasoning, and economic flexibility.
9. Command (Cohere) – Command R+ features 104B parameters and a 128,000-token context window, purpose-built for RAG. Excels at long-form processing, multi-turn conversations, and enterprise accuracy. Hybrid licensing – free for personal use, licensed for commercial.

Each model’s details were gathered from various sources, including developer websites and industry analyses, to ensure accuracy. For instance, GPT from OpenAI is noted for its conversational and multimodal capabilities, with ChatGPT-4o being a flagship model released in May 2024, as confirmed by GPT-4o explained: Everything you need to know.

Comparison.

To assist in selection, the models are compared across several dimensions:

Parameter Count

The number of parameters indicates a model’s capacity. DeepSeek leads with 671B parameters, though its MoE architecture activates only 37B at a time, making it efficient. GPT follows with over 175B, while LlaMA and Mistral have 70B and 24B, respectively. Notably, Claude’s parameters are not disclosed, adding a layer of mystery to its capabilities.

Context Window

The context window determines how much text a model can process at once. Claude stands out with 200,000 tokens, ideal for long documents, while GPT, LlaMA, Qwen, and Command offer 128,000 tokens. Gemini’s Gemma 2 has a smaller 8,200-token window, which might limit its use for extensive texts.

Performance on Benchmarks

Performance varies by task. DeepSeek-R1 ranks 4th on Chatbot Arena and is a top open-source model, while Qwen2.5-Max outperforms DeepSeek V3 in some benchmarks. Claude 3.5 Sonnet scores 49.0% on SWE-bench, indicating strong coding capabilities. Mistral Small 3 is 3x faster than LlaMA 3.3, highlighting its real-time efficiency.

Accessibility

Accessibility is crucial for adoption. Open-source models like DeepSeek, LlaMA, Mistral, and LG AI (for non-commercial use) allow customization, while proprietary models like GPT and Claude require API access or subscriptions. Gemini offers a dual approach with proprietary Gemini 2.0 and open-source Gemma 2, providing flexibility.

Cost

Cost impacts commercial viability. Open-source models like DeepSeek and Mistral can be deployed on own infrastructure, reducing costs, while proprietary models like GPT and Claude involve API or subscription fees. For example, Claude’s subscription can reach $2,304/month, as noted in the survey.

Key Features.

Each model has niche strengths:

• GPT excels in multimodal interactions, suitable for voice and vision tasks.
• DeepSeek is cost-efficient for reasoning and RAG, appealing to budget-conscious users.
• Qwen’s low-latency suits real-time applications like chatbots.
• LG AI’s bilingual capabilities and optimisation make it ideal for diverse research.
• LlaMA’s multimodal and multilingual features cater to global audiences.
• Claude’s large context window is perfect for long-form content.
• Mistral’s speed is unmatched for real-time data processing.
• Gemini’s speed and Gemma 2 offer economic options for multimodal needs.
• Command’s accuracy and RAG optimisation are great for multi-turn conversations.

Choosing the Right LLM.

Selecting an LLM depends on the application:

• Real-time Applications: Mistral and Qwen, with low latency, are suitable for chatbots and virtual assistants.
• Long-form Text Generation: Claude and Command, with large context windows, are ideal for document processing.
• Customisation and Cost-effectiveness: Open-source models like DeepSeek, LlaMA, and Mistral are preferable for research and development, especially with limited budgets.
• Multimodal Capabilities: GPT, LlaMA, and Gemini are best for tasks involving images or audio, such as content creation with multimedia.

This analysis highlights the diversity of LLMs, ensuring users can match models to their specific needs. For instance, a startup might choose LlaMA for its open-source nature and multimodal features, while a large enterprise might opt for Claude for its advanced conversational capabilities.

Unexpected Detail.

An interesting trend in 2025 is the rise of hybrid licensing, as seen with Command (Cohere), which is open for personal use but requires a license for commercial applications. This approach balances accessibility and revenue, potentially influencing future LLM development strategies.
