GPT-5 API in India

GPT-5 is OpenAI's frontier model — the one to reach for when reasoning depth, code quality, and nuanced analysis matter more than raw cost. On unoblox it's priced at ₹126 per million input tokens and ₹1008 per million output tokens, billed on a monthly GST invoice.

GPT-5 versus GPT-4o

	GPT-5	GPT-4o
Input (₹/1M)	₹126	₹252
Output (₹/1M)	₹1008	₹1008
Positioning	Frontier reasoning, code, multimodal	Fast, multimodal, production-proven

GPT-5 is exactly half the input price of GPT-4o on unoblox, with output priced the same — so for reasoning-heavy work, it's rarely the more expensive choice. The practical takeaway: there's little reason to default to GPT-4o for text-only reasoning tasks anymore, since GPT-5 costs less on input and matches it on output.

When to use GPT-5

• Research and analysis — synthesizing complex information, spotting patterns, generating hypotheses.
• Frontier coding — debugging hard problems, optimizing algorithms, architecting systems.
• Scientific work — multi-step derivations, literature synthesis, hypothesis checking.
• Legal and contract review — parsing dense clauses and flagging risk.

Quick integration

1. Create an account → https://unoblox.ai/sign-in (a couple of minutes).
2. Generate an API key → copy it into your environment.
3. Point at unoblox → base_url = https://api.unoblox.ai/v1, model openai/gpt-5.

from openai import OpenAI

client = OpenAI(api_key="ub-gw-...", base_url="https://api.unoblox.ai/v1")
response = client.chat.completions.create(
    model="openai/gpt-5",
    messages=[{"role": "user", "content": "Design a novel data structure for..."}],
    max_tokens=4000,

Why unoblox for GPT-5

• Rupee billing — the rate you're quoted is the rate you pay, no billing surprises.
• GST invoice — automatic monthly invoice with input-tax credit eligibility.
• One key, many models — switch between GPT-5, Claude, Qwen, and DeepSeek in the same integration.
• Transparent spend — a real-time dashboard shows rupee cost per request.

Frequently asked questions

Is GPT-5 worth the extra cost over GPT-4o on output? Output is priced the same on both, and GPT-5 is actually cheaper on input — so for most reasoning-heavy work, GPT-5 is the better value, not just the better model.

Can I use streaming with GPT-5? Yes — full streaming support, with tokens arriving in real time for a responsive UI.

Is GPT-5 slower than GPT-4o because it reasons more? Reasoning-heavy prompts take longer to fully resolve than a short chat reply simply because the model produces more output tokens working through the problem — you're billed for those tokens at the standard output rate, nothing extra.

Is data retained or used for training? No — requests aren't logged for model training, and data residency stays in India.

Can I use vision with GPT-5? Yes — pass images in the messages array; they're billed as additional input tokens at the standard rate.
