Gemini vs GPT-5: which AI API for India?

Gemini vs GPT-5: which should you use?

Google Gemini and OpenAI GPT-5 are the top general-purpose AI models. Gemini excels at long-context reasoning and multimodal tasks; GPT-5 leads in coding and mathematical reasoning. In India, unoblox delivers both through one OpenAI-compatible endpoint, billed in rupees on a single GST invoice — no international card or international bank needed.

Model comparison

Feature	Gemini	GPT-5
₹ Input cost	See live pricing	₹126/1M tokens
₹ Output cost	See live pricing	₹1008/1M tokens
Context window	1M+ tokens	128K tokens
Reasoning depth	Very good (long docs)	Exceptional (code, math)
Vision capability	Native multimodal	Strong
API latency	Fast	Very fast
Real-time search	Yes	No

When to use Gemini

Gemini shines for long-document analysis, multimodal workflows, and search-powered answers. Use it if your input often exceeds 100K tokens or you need image/video understanding. The million-token context is unmatched.

When to use GPT-5

GPT-5 is best for code generation, complex reasoning, and agent orchestration. Its faster reasoning and sharper accuracy on STEM tasks make it ideal for developers. Lower ₹ latency also speeds up agentic loops.

Frequently asked questions

Q: Can I run both Gemini and GPT-5 with a single API key? Yes. One ub-gw-... key works with every model on unoblox. Switch by changing the model parameter.

Q: What's the ₹ cost difference at scale? Both are competitively priced in rupees. Check live ₹ rates on unoblox for exact tokens (Gemini varies by model version).

Q: Does Gemini's long context add latency? Not significantly. Gemini efficiently processes million-token inputs without proportional slowdown.

Q: Which model is better for a RAG system? GPT-5 for recall-accuracy pipelines; Gemini for flexible, long-memory retrieval.

Q: Can I switch models mid-deployment? Yes—just redeploy with a new model ID. No code rewrite needed.

Q: Is there a free tier? Qwen 1.7B is free (₹0). Gemini and GPT-5 are paid; check live pricing.
