GPT-5.4 nano API in Russia — no VPN, no foreign card
GPT-5.4 nano is, in OpenAI's words, its cheapest GPT-5.4-class model, meant for simple high-volume tasks. OpenAI will remove it from the API on April 1, 2027. Connect through RuAPI: pay in USDT from $5, no subscription, your key right after sign-up.
from openai import OpenAI
client = OpenAI(
api_key="sk-...",
base_url="https://www.ruapi.ai/v1",
)
resp = client.chat.completions.create(
model="gpt-5.4-nano",
messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)Replace sk-... with a key from the RuAPI Console — the model gpt-5.4-nano is already set.
GPT-5.4 nano API price
Current price in US dollars — the same as on the pricing page. Pay in USDT, pay as you go, no subscription.
| model | input $ / 1M | output $ / 1M |
|---|---|---|
| gpt-5.4-nano | $0.24 cache read $0.0240 | $1.50 |
Input is the regular price of input tokens, “cache read” is the price of input tokens served from the prompt cache, output is the price of output tokens. The price in your account may be lower.
What is GPT-5.4 nano
OpenAI targets GPT-5.4 nano at simple high-volume work: classification, data extraction, ranking and subagents. The model's only snapshot is gpt-5.4-nano-2026-03-17. It has a 400K-token context window (up to 272K of input), replies of up to 128K tokens and knowledge up to August 31, 2025. It takes text and images and answers in text, with function calling, structured outputs and prompt caching. Reasoning is off by default (none) and can be raised from low to xhigh.
Note: OpenAI has deprecated the model, will remove it from the API on April 1, 2027, and names gpt-6-luna as the replacement. Until then gpt-5.4-nano keeps working on RuAPI through /v1/chat/completions and /v1/responses, so existing integrations will not break overnight. For new projects we recommend gpt-6-luna: on OpenAI's price list it costs less, and its knowledge is more recent.

What it’s good for
- Integrations already running on gpt-5.4-nano, until you move to gpt-6-luna
- Sorting and tagging support requests, reviews and tickets
- Ranking search results and picking the best answer
- Short helper steps in agents that need no reasoning
When another model is a better fit
- GPT-6 Luna — OpenAI's official replacement: cheaper on OpenAI's price list, newer knowledge and a larger context — the pick for any new project
- GPT-5.4 mini — The larger model of the same GPT-5.4 family — when nano cannot handle the task
