Introduction

Gemini represents Google's most ambitious AI initiative, designed as a native multimodal model family de zéro. Contrairement à systems that bolt image or audio capacités onto text models, Gemini was built to transparently understand and process text, images, audio, video, and code together -- permettant more natural reasoning across different types of information in a single conversation.

Developed by the merged Google Brain and DeepMind équipes, Gemini is the successor to LaMDA and PaLM 2. The name "Gemini" refers to both the underlying model family and the consumer-facing chat application (formerly known as Bard). Google has invested heavily in making Gemini the AI backbone of its entire product écosystème, from Search and Fonctionnepace to Android and Cloud.

Gemini's standout comprend include massive fenêtre de contextes (jusqu'à 2 million tokens for traitement entire codebases, books, or hours of video), deep intégration with Google services (Search, Gmail, Docs, Sheets, Drive), and a tiered model family (Nano, Flash, Pro) that balances speed, capability, and cost for different cas d'utilisations. With the 2.5 génération, Gemini introduced "thinking" capacités for enhanced reasoning on complex problems, ce qui en fait compétitif with le/la meilleur(e) reasoning models disponible.
