GPT-4 Turbo vs GPT-5.4: Which Should You Choose?

Choosing between GPT-4 Turbo and GPT-5.4 depends on your priorities: cost efficiency, context length, or raw capability. GPT-5.4 is the more affordable option at $2.50/1M input tokens75% cheaper than GPT-4 Turbo. Meanwhile, GPT-5.4 offers a significantly larger context window at 1,050,000 tokens vs 128,000 for GPT-4 Turbo.

Both models are in the flagship category, making this a direct head-to-head comparison. At scale — say 10,000 requests per day — the cost difference adds up: GPT-5.4 would save you roughly $4,500.00/month compared to GPT-4 Turbo. For startups and indie developers, that difference can be significant.

Output costs matter too. GPT-4 Turbo charges $30.00/1M output tokens vs $15.00 for GPT-5.4. For generation-heavy workloads (content creation, code generation, summarization), output pricing often dominates your bill. GPT-5.4 has the edge here at $15.00/1M output tokens.

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