GPT-5.4 API Pricing 2026: Latest Forecast, Scenarios & Cost Comparison
GPT-5.4 API Pricing: What to Expect in 2026
GPT-5.4 is now listed on OpenRouter with published token pricing. If you are planning API budget now, you can combine this listing with GPT-5.x historical patterns to build a safer rollout plan.
Update (March 6, 2026)
$2.50 / 1M input, $0.625 / 1M cached input, and $20.00 / 1M output, with a 1M context window and 128K max output.This is a marketplace listing and may differ from future OpenAI direct billing tiers or enterprise contracts. We still keep scenario analysis below for budget planning across pricing paths.
GPT-5.x Pricing History
| Model | Release | Price (Input / Output, per 1M tokens) | Context | Notes |
|---|---|---|---|---|
| GPT-5.0 | Aug 2025 | $1.25 / $10.00 | 400K context / 128K max output | Launch pricing |
| GPT-5.1 | Nov 2025 | $1.25 / $10.00 | 400K | Same price, same core context tier |
| GPT-5.2 | Dec 2025 | $1.75 / $14.00 | 400K | 40% increase for stronger reasoning |
| GPT-5.2 Pro | Dec 2025 | $21.00 / $168.00 | 400K | Separately priced premium tier (Standard) |
GPT-5.3 (gpt-5.3-chat-latest / gpt-5.3-codex) | Mar 2026 | $1.75 / $14.00 | 400K | Listed API pricing (Standard) |
| GPT-5.4 | Mar 2026 | $2.50 / $20.00 | 1M context / 128K max output | Cached input: $0.625 / 1M |
Key pattern: OpenAI may keep base flagship tiers relatively stable across close generations (for example, GPT-5.0 to GPT-5.1), but can raise price on major reasoning upgrades (GPT-5.2) and price dedicated premium tiers much higher (GPT-5.2 Pro).
GPT-5.4 Pricing Scenarios
Scenario A: Flat Pricing ($1.75 / $14.00), Probability ~60%
- GPT-5.4 replaces GPT-5.2 as the default flagship.
- Extreme thinking mode could be exposed as a separately priced premium tier, while base GPT-5.4 stays flat.
- OpenAI absorbs part of long-context compute cost due to market pressure.
Scenario B: Price Increase ($2.50 / $15.00-$20.00), Probability ~40%
- 1M+ context, extreme mode, and full-resolution vision increase compute cost.
- OpenAI positions GPT-5.4 above GPT-5.2 as a premium tier.
- GPT-5.2 remains as a value option.
The current OpenRouter listing aligns with the upper band of Scenario B.
Cached Input Pricing Matters
GPT-5.2 applies a 90% discount on cached input tokens ($0.175 per 1M cached tokens). If GPT-5.4 keeps similar cached pricing, repeated prompts could become much cheaper in practice, especially with large shared system context.
Competitive Price vs Capability Snapshot
Reference prices below are public list prices and can vary by tier and token-length bracket.
| Model | Price (Input / Output, per 1M tokens) | Context | Positioning |
|---|---|---|---|
| DeepSeek Chat | $0.27 / $1.10 (cache-miss input) | 64K | Budget and high-volume tasks |
| Gemini 2.5 Flash | $0.30 / $2.50 | 1M | Fast, low-cost, long-context tasks |
| GPT-5.1 | $1.25 / $10.00 | 400K | General-purpose prior generation |
| Gemini 3.1 Pro | $2.00-$4.00 / $12.00-$18.00 | 1M | Multimodal and long-context workloads |
| GPT-5.2 | $1.75 / $14.00 | 400K | Deep reasoning and coding |
| GPT-5.4 | $2.50 / $20.00 (cached input: $0.625) | 1M | Flagship-tier pricing, rollout eval needed |
| Claude Sonnet 4.6 | $3.00 / $15.00 | 1M (beta) | Coding and agentic tasks |
| Claude Opus 4.6 | $5.00 / $25.00 (base), $10.00 / $37.50 (>200K premium) | 1M (beta) | Research and complex reasoning |
At the current OpenRouter listing, GPT-5.4 output pricing ($20.00) is above Gemini 3.1 Pro in both common token brackets, but still below Claude Sonnet 4.6 output pricing in higher-cost scenarios. For many teams, the decision now is quality/latency gains vs. higher output cost, not just raw token price.
EvoLink GPT-5.4 Pricing Scenarios (Pending EvoLink Rollout)
Because GPT-5.4 pricing can differ by platform and contract tier, these are EvoLink planning scenarios, not final posted EvoLink prices.
- Scenario A (if OpenAI keeps a GPT-5.2-like baseline): around $1.40 / 1M input, around $11.20 / 1M output
- Scenario B (if OpenAI launches GPT-5.4 as a premium tier): around $2.00 / 1M input, around $12.00-$16.00 / 1M output
These figures are budget estimates only and should not be treated as a public quote. Final EvoLink pricing will be published after EvoLink rollout and pricing-page confirmation.
Cost Optimization Strategies
1. Use Prompt Caching Aggressively
With 1M+ context, repeated system prompts can dominate input cost. Keep stable context blocks identical across requests to maximize cached-token discounts.
2. Route by Task Complexity
Not every request needs extreme reasoning. Send simple requests to lower-cost models (GPT-5.1, DeepSeek Chat, Gemini Flash), and reserve GPT-5.4 for hard tasks.
3. Watch Token Efficiency
Larger context does not mean every task should consume larger context. Measure whether 1M context improves success rate enough to justify higher input spend.
4. Optimize for Cost per Task, Not Cost per Token
A higher-priced model that solves in one pass can still be cheaper than a low-cost model requiring retries. Track total cost per successful outcome.
FAQ
How much could a typical GPT-5.4 API call cost?
A rough estimate for a 2,000-token input and 500-token output is about $0.01-$0.015 under these projections.
Will extreme thinking mode likely cost extra?
Probably yes. GPT-5.2 already has tiered reasoning behavior, and a deeper mode usually implies higher effective token usage and latency.
Is GPT-5.4 worth upgrading from GPT-5.2?
It depends on your workload. If you need 1M+ context or deeper reasoning, the upgrade may be justified. If 400K context is already enough, GPT-5.2 may remain the better value option.
How does EvoLink pricing work?
Usage is token-based with no monthly minimum. You buy credits and use one API key across multiple models.
