Deep Architectural Overview
Gemini 2.5 Flash introduces interleaved text-and-image outputs. Rather than calling a secondary image generation model, Gemini 2.5 Flash natively outputs pixel representations alongside conversational text.
Strengths & Considerations
Core Strengths
- Native inline image generation and editing
- Sub-second multimodal latency
- Upgraded coding and tool calling capabilities
Known Limitations
- Image resolution maxes at 1024x1024 natively without upscaling
