Picking between Gemini and GPT depends on your use case, budget, and privacy constraints. Here's a factual, up-to-date comparison to decide in minutes.
Technical specs
| Model | Gemini | GPT |
|---|---|---|
| Vendor | OpenAI | |
| Reference variant | Gemini 2.5 Pro | GPT-4o |
| Context window | 2000K tokens | 128K tokens |
| Input price | $1.25 $ / 1M tokens | $2.5 $ / 1M tokens |
| Output price | $5 $ / 1M tokens | $10 $ / 1M tokens |
| Knowledge cutoff | 2025-01 | 2024-10 |

Strengths of Gemini
- • Massive context window (2M tokens, ~1,500 pages)
- • Native Google Search integration for fresh data
- • Native vision and video understanding
- • Competitive input pricing
Strengths of GPT
- • Native multimodal (text, image, audio, voice)
- • Built-in image generation (DALL-E)
- • Vast plugin and integration ecosystem
- • Fast streaming response time
Limits of Gemini
- • Output sometimes less polished than Claude
- • Occasionally verbose without added information
- • API less mature than OpenAI/Anthropic
Limits of GPT
- • Smaller context window than Claude/Gemini
- • Sometimes shallow on deep analysis
- • Filtering occasionally over-restrictive on neutral topics
Which one should you pick?
Pick Gemini if…
Very long context (full books), live research (Google integration), video multimodality.
Pick GPT if…
Versatility, multimodality (vision/audio), image generation, vast ecosystem.
Still undecided?
The best is to test both on a real question from your daily workflow. On Ask Aurel you can query Gemini and GPT side by side (Compare mode) for a few cents, no subscription, and judge by results.
Frequently asked questions
Gemini or GPT: which is cheaper?
Gemini is overall cheaper ($1.25 per 1M input tokens, $5 per 1M output) than GPT ($2.5 input, $10 output). The real cost depends on your input/output ratio: heavy output use widens the gap in favor of the cheaper one.
Gemini or GPT: which is better for code?
GPT is generally preferred for code by developers in 2026. Gemini may fit specific constraints (budget, ecosystem).
Gemini or GPT: which is GDPR-friendly?
Neither Gemini nor GPT is European. Both provide GDPR-compliant Data Processing Agreements (DPA), but data transits through the US (or China for DeepSeek). For full sovereignty, Mistral AI remains the European reference.
What's the context window for Gemini vs GPT?
Gemini accepts 2000K tokens of context, GPT 128K. Gemini has the larger window, which matters for analyzing long documents (books, dossiers, codebases) in one request.
