Google Gemini Flash vs Pro

What are the differences among Gemini 1.5 Pro Flash, Gemini 1.5 Pro, Gemini 1.0 Pro?

Gemini 1.5 Flash, Gemini 1.5 Pro and Gemini 1.0 Pro are all powerful tools, but they cater to different needs and offer varying capabilities. Here’s a breakdown of their key differences:

Modality

Gemini 1.5 FlashGemini 1.5 ProGemini 1.0 Pro
The fastest and most cost-effective Gemini multimodal model, ideal for high-volume, latency-sensitive tasks.Truly multimodal, handling text, images, videos, and audio seamlessly.Primarily text-based, with limited image and video support (1.0-pro-vision).

Input/Output

All models support a wide range of inputs and outputs, but the Gemini 1.0 Pro is limited to 32,760 tokens and primarily text-based outputs.

Function calling: Integrate external systems for actions beyond the model’s knowledge.Same as FlashFocuses on text generation, translation, and basic image/video understanding.
System instructions: Provide guidance for better performance and desired response styles.Same as FlashOffers temperature and topK parameters for controlling response creativity.
Grounding with Google Search: Access real-time information for more accurate and relevant results (text only).Same as Flash
Enhanced safety controls: Fine-tune response filtering based on specific categories and probability thresholds.Same as Flash

Cost

While Gemini 1.5 Pro is 20 times more expensive than Gemini 1.0 Pro for both input and output, this is due to its enhanced capabilities in handling larger and more complex data sets and its ability to process multimodal inputs seamlessly. On the other hand, Gemini 1.5 Flash has the same cost per input and output as Gemini 1.0 Pro, but it offers the fastest processing speeds, making it ideal for high-volume, latency-sensitive tasks.
