Grok vs GPT-5 in India: what unoblox offers

If you're comparing Grok and GPT-5 for a project in India, one fact settles part of it: Grok is not available on unoblox, and the GPT-5 models are. We don't serve Grok, so this page doesn't make claims about it. It covers five of the GPT-5-family models you can call today, billed in rupees. The catalog also lists GPT 5.4, 5.5 and 5.6 variants; see the model list.

A month at 10 M input + 2 M output (no cache hits)

• GPT 5: ₹3,291.18
• GPT 5-mini: ₹658.16
• GPT 5-nano: ₹131.60

Reasoning tokens are billed as output, so a reasoning-heavy request can produce more output tokens than the visible answer suggests. Pricing & credits covers this.

Picking a GPT-5 tier

• GPT 5-nano: the lowest rate in this table.
• GPT 5-mini: the middle price point.
• GPT 5, 5.1, 5.2: the highest rates in this table.

Frequently asked questions

Is Grok available on unoblox? No. Grok is not in the catalog.

Do I need an OpenAI account to use GPT-5 here? No. Your unoblox key is enough, and billing is in rupees.

Does GPT-5 run in India on unoblox? No. It runs at the upstream provider outside India. What's India-specific is rupee billing, a GST invoice for each top-up, and one endpoint.

How is usage billed? Usage is paid from a prepaid rupee wallet. GST at 18% is added when you top up (pay ₹118 and ₹100 of credit lands in your wallet), and one GST tax invoice is issued for each top-up; individual requests carry no separate invoice.
