GPT-5.4 Pricing Breakdown: How It Compares to Claude, Gemini & DeepSeek

OpenAI released GPT-5.4 on March 5, 2026 — their most capable model yet with a 1M+ token context window. But at $2.50/$15.00 per million tokens, is it worth the cost? We break down the numbers.

GPT-5.4 Pricing at a Glance

ModelInputOutputCachedContext
GPT-5.4$2.50$15.00$0.251.05M
GPT-5.4 (>272K)$5.00$22.50$0.501.05M
GPT-5.4 Pro$30.00$180.00$3.00400K

All prices in USD per 1 million tokens. GPT-5.4 doubles input price and adds 50% to output price for prompts exceeding 272K tokens.

GPT-5.4 vs GPT-5.2: What Changed?

Input Price
$1.75$2.50+43%
Output Price
$14.00$15.00+7%
Context
400K1.05M+163%

Input price jumped 43%, but the 2.6× larger context window and significantly improved coding performance (unifying Codex and GPT lines) justify the premium for most production workloads. Output price only increased 7% — a good sign for generation-heavy tasks.

Head-to-Head: GPT-5.4 vs the Competition

* Estimated cost per 1K-token request (500 input + 500 output)

Key takeaways:

  • GPT-5.4 matches GPT-5.2 on cost-per-request despite being more expensive per token — OpenAI claims 47% fewer tokens needed thanks to tool search optimization.
  • Gemini 3 Pro Preview is 9% cheaper at $0.0080 per request, with a similar 1M context window. The value leader among frontier models.
  • DeepSeek V3 remains 10× cheaper at $0.0009 per request. For cost-sensitive workloads, DeepSeek is still unbeatable.
  • Claude Sonnet 4.6 is 19% more expensive than GPT-5.4 per request, but offers strong coding performance. Claude Opus 4.6 at $0.0175 is 2× GPT-5.4's cost.

When to Choose GPT-5.4

✅ Choose GPT-5.4 when:

  • You need a massive context window (1M+ tokens)
  • Coding and agentic tasks are your primary use case
  • You can leverage prompt caching ($0.25/M = 90% savings)
  • Tool search can reduce your total token usage

⚡ Consider alternatives when:

  • Cost is the top priority → DeepSeek V3 ($0.30/$1.20)
  • You need a similar context window cheaper → Gemini 3 Pro ($2.00/$12.00)
  • Simple, fast tasks → GPT-5 Mini ($0.25/$2.00) or GPT-5 Nano ($0.10/$0.40)
  • Maximum reasoning accuracy → GPT-5.4 Pro ($30/$180, but 12× the cost)

The Bottom Line

GPT-5.4 is a solid upgrade over GPT-5.2 with a dramatically larger context window and improved token efficiency. The 43% input price increase is offset by needing fewer tokens per task. For most production workloads, GPT-5.4 will cost roughly the same as GPT-5.2 while delivering better results.

That said, Gemini 3 Pro Preview and DeepSeek V3 remain compelling alternatives if you're optimizing for cost. The AI pricing landscape in March 2026 is the most competitive it's ever been.
