this id pins the microsoft azure ai deployment, with no routing and no failover. the managed id on the canonical page routes across all 3 providers instead

main.py
from openai import OpenAI client = OpenAI(    api_key="YOUR_REQUESTY_API_KEY",    base_url="https://router.requesty.ai/v1",) response = client.chat.completions.create(    model="azure/gpt-5.4@eastus2",    messages=[        {"role": "user", "content": "Explain quantum computing in one paragraph."},    ],) print(response.choices[0].message.content)

Change the base url to https://router.requesty.ai/v1, use your Requesty key, set the model to the id above. Existing OpenAI SDK code needs no other edit, and the same key reaches every other model in the catalog. Browse all models

notes

reference

GPT 5.4 is OpenAI's frontier model designed for complex professional workloads, with strong reasoning, high reliability, and improved token efficiency on hard tasks. It features a 1M+ token context window (922K input, 128K output) with support for text and image inputs, enabling large scale reasoning, coding, and multimodal workflows within a single system.

questions 7

How much does gpt-5.4 cost?
gpt-5.4 is priced at $2.50 per million input tokens and $15.00 per million output tokens when accessed via Requesty. Prompt caching is supported, which can cut effective input cost by up to 90% on repeated context. Requesty charges exactly what the upstream provider charges, we don't add markup.
What is the context window of gpt-5.4?
gpt-5.4 has a context window of 1.1M tokens, with a maximum output of 128K tokens per response. That is roughly 1,400 words of input you can fit in a single prompt.
How does gpt-5.4 perform on benchmarks?
gpt-5.4 scores 92.0% on GPQA Diamond, 87.1% on τ²-Bench, 71.1% on Coding Index. The benchmarks pane shows every published result, each normalised to 100.
What can gpt-5.4 do?
gpt-5.4 supports vision input, tool calling, extended reasoning, prompt caching, structured outputs (JSON schema). You can call it through any OpenAI-compatible client by pointing base_url to Requesty.
How do I use gpt-5.4 with the OpenAI SDK?
Install the OpenAI SDK, set base_url to "https://router.requesty.ai/v1", set your API key to your Requesty key, and set the model to "azure/gpt-5.4@eastus2". The quickstart pane shows Python, JavaScript and cURL snippets.
Can I run gpt-5.4 through Requesty?
Yes. gpt-5.4 runs through Requesty's OpenAI-compatible API, served from Microsoft Azure AI in eastus2. You do not host the model yourself: point base_url at Requesty, set the model to "azure/gpt-5.4@eastus2", and requests are routed to the upstream provider with automatic failover. The same key gives you 600+ other models too.
What region is this deployment?
This variant of gpt-5.4 is deployed in eastus2. Region-specific endpoints matter for data residency, latency to your users, and compliance requirements such as GDPR and HIPAA. Other regions for the same model are listed on the canonical model page.
