Code examples

ourtoken.ai is OpenAI-compatible. This means your API key can be used with the OpenAI SDK. Just replace base_url with your ourtoken.ai address. See the examples below:

import openai

client = openai.OpenAI(
    api_key="YOUR_API_KEY",
    base_url="https://api.ourtoken.ai/v1"
)

response = client.chat.completions.create(
    model="gpt-5.4",
    messages=[
        {
            "role": "user",
            "content": "Hello!"

GPT 5.4 API Features for Developers

Use GPT 5.4 API on OurToken for clear GPT 5.4 API pricing, coding workflows, multimodal input, and cost-aware production routing.

API Access

Call GPT 5.4 API through OurToken's unified endpoint and keep your integration close to an OpenAI-compatible workflow. Developers can test GPT 5.4, compare provider options, and move from evaluation to production without rebuilding model access.

Pricing Clarity

Review GPT 5.4 API pricing before scaling high-volume traffic. OurToken shows the current GPT 5.4 price for input and output tokens, helping teams estimate GPT 5.4 API cost for coding, document analysis, and automated workflows.

Coding Workflows

Use GPT 5.4 for code generation, debugging, refactoring, software planning, and instruction-following tasks. This section also serves gpt 5.4 codex search intent by explaining how GPT 5.4 API can support Codex-style developer workflows.

Long Context

Use GPT 5.4 API when your product needs large documents, longer prompts, code-heavy context, or extended business workflows. The 256K context window gives teams room to include evidence, instructions, and task constraints in one request.

Multimodal Input

Send text and image inputs for document understanding, visual analysis, and multimodal product features. GPT 5.4 API works well for teams that need reasoning over written instructions, screenshots, diagrams, or image-backed support workflows.

Structured Output

Build predictable application logic with function calling, structured responses, and explicit output formats. GPT 5.4 API can support production systems where downstream automation needs stable JSON-like results, tool calls, and repeatable behavior.

How to Use GPT 5.4 API on OurToken

Create an API key, choose GPT 5.4 API, compare pricing, then test coding, structured output, and production quality.

Generate API Key

Create an OurToken API key and store it in a secure server-side environment variable. This gives your backend a stable way to call GPT 5.4 API without exposing credentials in client-side code.

01

Select Model ID

Use gpt-5.4 as the model value when sending chat completions requests. Keep your documentation focused on GPT 5.4 API access so developers can compare model behavior, provider routes, and deployment requirements.

02

Call Unified API

Send requests through the OurToken unified API endpoint with an OpenAI-compatible client. Teams can test GPT 5.4, compare response quality, and avoid rewriting code for every provider or routing option.

03

Compare Pricing

Before production rollout, compare GPT 5.4 API pricing against expected request volume, prompt size, and output length. Use the displayed GPT 5.4 price and GPT 5.4 API cost to estimate monthly workload spend.

04

Configure Outputs

Add structured output rules, schemas, or function calling when your application needs predictable responses. GPT 5.4 API can be tested with tool-heavy workflows before you connect it to production automation.

05

Test Codex Workflows

Run representative coding tasks such as review, debugging, patch planning, and repository-aware instructions. This is the right place to address gpt 5.4 codex intent while keeping the API setup clear for developers.

GPT 5.4 API FAQ

Answers about GPT 5.4 API pricing, GPT 5.4 price, API cost, Codex-style workflows, model access, and provider comparisons.

01

What is GPT 5.4 API?

GPT 5.4 API is an API route for using OpenAI's GPT 5.4 model in applications that need reasoning, coding support, image input, function calling, and structured output. On OurToken, teams can evaluate GPT 5.4 API with model ID details, pricing, and unified access.
02

How much does GPT 5.4 API pricing cost on OurToken?

GPT 5.4 API pricing on OurToken follows the current project data: $1.25 per million input tokens and $7.50 per million output tokens, with original pricing shown as $2.50 and $15.00. Use the GPT 5.4 price to estimate spend before scaling traffic.
03

What is GPT 5.4 API cost for production workloads?

GPT 5.4 API cost depends on prompt size, output length, request volume, and how often your app uses tool or structured-output workflows. Start with the displayed GPT 5.4 API pricing, then test representative prompts to estimate real monthly usage.
04

Is GPT 5.4 API useful for Codex-style coding tasks?

Yes. GPT 5.4 API can support debugging, code review, refactoring, patch planning, and instruction-following workflows. Searches for gpt 5.4 codex usually point to developers comparing GPT 5.4 with Codex-style coding assistants and agent workflows.
05

How do I access GPT 5.4 API?
