AIs and their limitations

 AI popularity and useage has been growing exponentially. There are 6 majors AIs and they have their own strengths and weaknesses. 

1. GPT-4.5 (OpenAI)

Exceptional broad knowledge, natural language processing, and creative content generation; integrates reasoning from o-series for complex tasks.

High cost for API usage; can produce hallucinations or biased outputs in niche scenarios.

2. Grok 3 (xAI)

Powerful reasoning and truth-seeking capabilities; trained on massive scale with Colossus supercomputer for accurate, insightful responses.

Limited multimodal features compared to competitors; access restricted to subscribers on certain platforms.

3. Gemini 2.5 Pro (Google)

Superior multimodal understanding (text, images, video); massive context window (over 1M tokens) for handling long documents and complex queries.

Slower response times in Deep Think mode; occasional inconsistencies in creative tasks.

4. Claude 4 (Anthropic)

Top-tier coding and technical writing; strong ethical alignment and natural language generation for collaborative development.

Lacks persistent memory across sessions; higher latency for very large-scale computations.

5. Llama 4 (Meta)

Highly customizable open-source model; efficient for on-device deployment and fine-tuning in specialized applications.

Requires significant computational resources for optimal performance; less out-of-the-box reasoning than closed models.

6. DeepSeek R1 

(DeepSeek AI)Outstanding cost-efficiency (up to 30x cheaper); excels in complex STEM reasoning and research tasks.

Primarily text-focused with limited multimodal support; potential language biases toward English/Chinese contexts.

GPT-4.5 (OpenAI) Broad consumer base, especially 18-34 year olds (53% of users); mid-career professionals (35-54, 33%); 56% male, 44% female; strong in US (77M MAU), India, Brazil; appeals to students, writers, and general users for everyday tasks.Creative writing, email drafting, education, entertainment; 700M+ weekly active users; integrated into apps and APIs for broad accessibility.

Grok 3 (xAI)Under 35s (51%); 60-67% male; X (Twitter) users, Elon Musk fans, young tech enthusiasts; integrated with Telegram's 10M premium users; appeals to researchers and casual conversationalists.Real-time news/trends via X, coding, research, image generation; 18.8M users, surging post-Grok 3 launch; popular for sentiment analysis in crypto trading.

Gemini 2.5 Pro (Google)25-34 year olds (30-31%); 58% male, 42% female; global reach via Google ecosystem (US 18%, India 9%); students, researchers, professionals using Workspace/Search.Research (40%), productivity/creativity (50%); 350-450M MAU; embedded in Android, YouTube, enterprise tools like Salesforce/Adobe.

Claude 4 (Anthropic)Developers/programmers (37% of tasks coding-related); 18-34 year olds (52-77% male); enterprises (300K+), educators, scientists; high adoption in tech firms like Rakuten.Coding (Claude Code: 115K devs, 195M lines/week), technical writing, education/science; $5B run-rate revenue; strong in ethical AI/enterprise workflows.

Llama 4 (Meta)AI developers/researchers, startups, open-source communities; integrated into Meta apps (3.4B+ MAU across platforms); appeals to indie devs and cost-conscious builders.Custom fine-tuning, on-device deployment, multimodal apps; no direct consumer MAU tracked, but powers Meta AI for billions via Facebook/Instagram/WhatsApp.

DeepSeek R1 (DeepSeek AI)Young users (18-34, 60-70%); 66% male; cost-sensitive developers, students in Asia/US; rapid growth post-launch.STEM reasoning, coding, research; 97M MAU, 57M+ downloads; popular for affordable API access in education/career development.
