GPT-5.4 Pro vs GPT-5 Pro: Which Should You Choose?

Choosing between GPT-5.4 Pro and GPT-5 Pro depends on your priorities: cost efficiency, context length, or raw capability. GPT-5 Pro is the more affordable option at $15.00/1M input tokens — 50% cheaper than GPT-5.4 Pro. Meanwhile, GPT-5.4 Pro offers a significantly larger context window at 1,050,000 tokens vs 200,000 for GPT-5 Pro.

These models target different tiers: GPT-5.4 Pro is a reasoning model while GPT-5 Pro is flagship. This means they're optimized for different workloads. GPT-5.4 Pro is built for complex tasks that require deeper reasoning, while GPT-5 Pro offers better value for routine operations.

Output costs matter too. GPT-5.4 Pro charges $180.00/1M output tokens vs $120.00 for GPT-5 Pro. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5 Pro has the edge here at $120.00/1M output tokens.

Multimodal capabilities: Both models support vision (image understanding), so you can send images alongside text prompts with either option.
