# GPT-4 vs GPT-5: OpenAI Model Generation Comparison

GPT-5 represents OpenAI's next-generation model with significant improvements over GPT-4 in reasoning, multimodal understanding, and agentic capabilities. GPT-4 remains available as a cost-effective option for many applications.

## Comparison Factors

| Factor | GPT-4 | GPT-5 | Winner |
|--------|------|------|--------|
| Reasoning | Good reasoning, sometimes inconsistent on hard problems | Major leap — built-in chain-of-thought, stronger logic | b |
| Coding | ~50% SWE-bench, decent coding | 70%+ SWE-bench, much better code generation | b |
| Multimodal | Vision input, basic audio | Native multimodal: video, audio, images, documents | b |
| Pricing | Lower cost, well-established | Premium pricing, 2-3x GPT-4 cost | a |
| Reliability | Battle-tested, well-understood behavior | Newer, still being refined | a |

## Key Statistics

- GPT-5 shows 30%+ improvement on MMLU benchmark
- GPT-4: $10-30/MTok vs GPT-5: $15-75/MTok output
- GPT-5 supports native tool use with 95%+ success rate

## Choose GPT-4 When

- You need advanced reasoning capabilities.
- You work on complex tasks.
- You want the latest AI advancements.

## Choose GPT-5 When

- You require cost-effective solutions.
- You work on simpler applications.
- You prefer proven technologies.

## Verdict

GPT-5 is substantially more capable for reasoning, coding, and complex tasks. GPT-4 remains sufficient for simpler applications and is more cost-effective. Upgrade to GPT-5 for tasks requiring advanced reasoning; keep GPT-4 for cost-sensitive, simpler workloads.
