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
| Model | Input | Output | Cached | Context |
|---|---|---|---|---|
| GPT-5.4 | $2.50 | $15.00 | $0.25 | 1.05M |
| GPT-5.4 (>272K) | $5.00 | $22.50 | $0.50 | 1.05M |
| GPT-5.4 Pro | $30.00 | $180.00 | $3.00 | 400K |
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 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
| Model | Input | Output | Context | Est. Cost* |
|---|---|---|---|---|
| 🟢 GPT-5.4 | $2.50 | $15.00 | 1.05M | $0.0088 |
| 🟠 Claude Sonnet 4.6 | $3.00 | $15.00 | 200K | $0.0105 |
| 🔵 Gemini 3 Pro Preview | $2.00 | $12.00 | 1M | $0.0080 |
| 🟣 DeepSeek V3 | $0.30 | $1.20 | 164K | $0.0009 |
| 🟢 GPT-5.2 | $1.75 | $14.00 | 400K | $0.0088 |
| 🟠 Claude Opus 4.6 | $5.00 | $25.00 | 1M | $0.0175 |
* 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.
Real-World Cost Scenarios
Chatbot (10K messages/day)
~500 input + 500 output tokens per message
Code Review Agent
~5K input + 2K output tokens per review, 100 reviews/day
Document Processing
~50K input + 5K output, 500 docs/day
RAG Pipeline
~2K input + 1K output, 50K queries/day
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.
