GPT-4
OpenAI's most advanced multimodal language model that can process text, images, and code, serving as the benchmark for LLM performance.
GPT-4 is OpenAI's multimodal flagship (text + vision) – the benchmark for LLM performance and basis for ChatGPT Plus.
Explanation
GPT-4 (March 2023) brought multimodal capabilities. Variants: GPT-4 Turbo (128K context, cheaper), GPT-4o (omni, faster), GPT-4 Vision (image analysis). Basis for ChatGPT Plus, Copilot, Bing.
Marketing Relevance
GPT-4 is the de-facto standard for AI marketing: Text generation, image analysis, code creation. API enables custom integrations in marketing tools.
Example
GPT-4 Vision analyzes competitor ads: Uploads screenshots, AI identifies design patterns, messaging, CTAs and suggests improvements.
Common Pitfalls
More expensive than smaller models. Can hallucinate facts. Latency on complex queries. Knowledge cutoff.
Origin & History
GPT-4 was released March 2023. GPT-4 Turbo (Nov 2023) brought 128K context and lower prices. GPT-4o (May 2024) unified all modalities in a faster model.
Comparisons & Differences
GPT-4 vs. Claude 3 Opus
GPT-4 is more multimodal (native vision). Claude has longer context (200K) and focuses on safety/Constitutional AI.
GPT-4 vs. GPT-3.5
GPT-4 is significantly better at reasoning, code, and long contexts. GPT-3.5 is 10x cheaper and faster for simple tasks.
GPT-4 vs. Gemini Ultra
GPT-4 has larger ecosystem (ChatGPT, plugins). Gemini Ultra is multimodal from ground up with 1M context.
