GPT-4 vs GPT-3
Benchmarks, API Token Pricing, Context Window & Speed Comparison
Related topics (12)
GPT-4 by OpenAI and GPT-3 by OpenAI represent two of the frontier AI models analyzed in our comprehensive 2026 AI benchmark and LLM comparison. In this head-to-head evaluation, we examine API token pricing, context window specifications, inference speed (tokens per second), and empirical reasoning performance. From a pure economic perspective, GPT-3 holds a notable pricing advantage for token ingestion. On output generation, GPT-3 is more economical per million generated tokens. In data-heavy architectures requiring extensive repository or document analysis, GPT-4 provides an expanded memory horizon with 8K tokens. In latency-sensitive production environments, GPT-3 leads in tokens-per-second throughput, making it ideal for real-time conversational agents and high-concurrency workflows. Below is the complete empirical head-to-head breakdown across cost, speed, context, and capability matrices.
