9 Demos of Gemini Omni and Gemini 3.5 in Action: A Technical Deep Dive

## Introduction The landscape of multimodal AI has shifted dramatically in the past year. With the release of Gemini Omni and the updated Gemini 3.5 models, Google has pushed the boundaries of what is possible with real-time reasoning across text, images, audio, and video. As of June 2026, these models are not just research curiosities — they are production-ready tools that developers and enterprises can integrate into workflows. This article provides a detailed, data-driven analysis of nine specific demonstrations that showcase the capabilities of Gemini Omni and Gemini 3.5. These demos were officially presented by Google in a recent blog post ([Source](https://blog.google/innovation-and-ai/models-and-research/gemini-models/gemini-omni-3-5-videos/)) and highlight key improvements in latency, accuracy, and multimodal fusion. We will examine each demo, provide technical context, and offer practical advice on how to replicate similar results using the available APIs and SDKs. ## 1. Real-Time Video Understanding with Object Tracking One of the most impressive demos involves Gemini Omni processing a live video stream and tracking multiple objects simultaneously. In the demo, a user points a smartphone camera at a cluttered desk, and the model identifies a red pen, a white mug, and a USB hub — then tracks their positions as the camera moves. **Technical details:** Gemini Omni uses a novel attention mechanism that fuses spatial and temporal information at the token level. According to Google's technical report, the model achieves a 40% reduction in latency compared to the previous Gemini Ultra model when processing 30 fps video. The model can maintain consistent object tracking even when objects are partially occluded for up to 2 seconds. **How to replicate:** ```python import google.generativeai as genai model = genai.GenerativeModel('gemini-3.5-pro') video_file = genai.upload_file(path='desk_scene.mp4') response = model.generate_content([ "Track the red pen, white mug, and USB hub frame by frame. Return bounding box coordinates in JSON format.", video_file ]) print(response.text) ``` **Practical tip:** For best results, ensure the video is at least 720p and contains distinct colors or textures. The model performs better when objects have high contrast against the background. ## 2. Multimodal Code Generation from Hand-Drawn Diagrams Another standout demo shows a user sketching a simple flowchart on paper, photographing it, and asking Gemini 3.5 to generate Python code that implements the logic. The model not only interprets the shapes and arrows but also understands the intent behind annotations like "if temperature > 30" and "send alert." **Key metrics:** In internal benchmarks, Gemini 3.5 achieved a 92% accuracy rate on converting hand-drawn flowcharts to executable code — a 15% improvement over Gemini 2.5. The model handles up to 50 nodes per diagram. **Example workflow:** 1. Upload an image of the diagram. 2. Use the prompt: "Generate Python code that implements this flowchart. Use functions for each block." 3. The model outputs ready-to-run code with comments. ```python import google.generativeai as genai model = genai.GenerativeModel('gemini-3.5-pro-vision') image = genai.upload_file(path='flowchart.jpg') response = model.generate_content([ "Generate Python code that implements this flowchart. Use functions for each block.", image ]) print(response.text) ``` **Limitation:** The model struggles with extremely messy handwriting or diagrams with overlapping elements. Pre-processing the image with a simple contrast enhancement can improve results. ## 3. Audio-Visual Event Detection in Surveillance Feeds This demo focuses on security applications. Gemini Omni processes a 10-minute surveillance video and detects specific events: a person entering a restricted zone, a door opening, and a glass breaking. The model uses both audio cues (glass shatter, door creak) and visual cues (motion in a specific area). **Performance data:** The model achieves a 98% recall for event detection in controlled environments, with a false positive rate of only 2%. When tested on noisy outdoor footage, recall drops to 85%, but false positives remain below 5%. **API usage:** ```python model = genai.GenerativeModel('gemini-omni') video = genai.upload_file(path='warehouse_surveillance.mp4') response = model.generate_content([ "Detect all instances of: person entering restricted area, door opening, glass breaking. Return timestamps.", video ]) print(response.text) ``` **Practical advice:** For production deployments, consider combining Gemini Omni with a lightweight motion detector to pre-filter frames. This reduces API costs by up to 60%. ## 4. Interactive Storytelling with Dynamic Visuals A creative demo shows Gemini 3.5 generating a short animated story based on a text prompt, then allowing the user to change the setting mid-stream. The model regenerates the visuals and narrative in real time. In the demo, the story starts in a "futuristic city" and is switched to "underwater kingdom" — the model adapts within seconds. **Under the hood:** This capability relies on the model's ability to generate temporally consistent image sequences. Gemini 3.5 uses a diffusion-based approach combined with a temporal consistency module that tracks object positions across frames. **Latency:** Generating a 10-second animation takes approximately 8 seconds on the API. The model supports up to 60 frames per generation. **Code snippet:** ```python model = genai.GenerativeModel('gemini-3.5-pro') response = model.generate_content( "Create a 10-second animation of a futuristic city. Then change the setting to an underwater kingdom." ) # The response includes a video file URL print(response.video.url) ``` ## 5. Real-Time Language Translation with Lip-Sync This demo combines speech recognition, translation, and video generation. A user speaks in English, and Gemini Omni generates a video of the same person speaking in Spanish with synchronized lip movements. The model processes audio and video simultaneously, adjusting facial movements to match the translated speech. **Accuracy:** In tests, the lip-sync accuracy is 94% for English-to-Spanish and 89% for English-to-Mandarin. The model requires at least 30 seconds of source video to create a convincing avatar. **API call:** ```python model = genai.GenerativeModel('gemini-omni') video = genai.upload_file(path='speaker.mp4') response = model.generate_content([ "Translate the speech to Spanish and generate a new video with lip-sync.", video ]) print(response.video.url) ``` **Performance note:** Each minute of output video costs approximately 0.05 API credits and takes 2 minutes to generate. ## 6. Medical Image Analysis with Report Generation A healthcare-focused demo shows Gemini 3.5 analyzing chest X-rays and generating preliminary radiology reports. The model identifies potential abnormalities (e.g., nodules, effusions) and rates its confidence for each finding. **Benchmark results:** On the CheXpert dataset, Gemini 3.5 achieves an AUC of 0.94 for pneumonia detection, comparable to specialized medical models. The model generates reports in under 3 seconds per image. **Example prompt:** ```python model = genai.GenerativeModel('gemini-3.5-pro-vision') image = genai.upload_file(path='chest_xray.png') response = model.generate_content([ "Analyze this chest X-ray and generate a radiology report. List all findings with confidence scores.", image ]) print(response.text) ``` **Important caveat:** The model should not replace human radiologists. It is intended as a triage tool to prioritize urgent cases. ## 7. Multi-Source Data Fusion for Business Intelligence This demo integrates data from a CSV file, a PDF report, and a live API feed. Gemini 3.5 answers complex business questions like "What is the projected Q3 revenue based on current trends and historical data?" The model parses all three sources and produces a unified analysis. **Supported formats:** CSV, JSON, PDF, TXT, and live HTTP endpoints (via function calling). **Advanced usage:** ```python model = genai.GenerativeModel('gemini-3.5-pro') csv_data = genai.upload_file(path='sales_q1.csv') pdf_report = genai.upload_file(path='market_analysis.pdf') response = model.generate_content([ "Based on the CSV and PDF, project Q3 revenue. Use the latest API data for current trends.", csv_data, pdf_report ]) print(response.text) ``` ASI Biont supports connecting to Google Gemini and other AI models through its API integration layer — learn more at asibiont.com. ## 8. Autonomous Web Research Agent A demo shows Gemini 3.5 acting as an autonomous research assistant. Given a query like "Find the latest research on CRISPR applications in agriculture," the model browses multiple websites, extracts relevant information, and compiles a structured summary with citations. **Performance:** The agent achieves a 90% success rate on complex multi-step queries, completing tasks in an average of 45 seconds. It respects robots.txt and rate limits. **Implementation:** ```python model = genai.GenerativeModel('gemini-3.5-pro') response = model.generate_content( "Research the latest CRISPR applications in agriculture. Visit at least 3 sources. Return a summary with citations." ) print(response.text) ``` **Caution:** The agent may occasionally access paywalled content previews. Use with appropriate content filters. ## 9. Real-Time Collaborative Drawing with Voice Commands The final demo showcases a collaborative drawing tool where a user draws a rough sketch of a house while speaking commands: "Add a red roof," "Make the door bigger." Gemini Omni interprets both the sketch and voice, updating the drawing in real time. **Latency:** Voice-to-visual update takes less than 1 second. The model handles multiple simultaneous commands (e.g., "Change the roof to blue and add a chimney" ). **Technical stack:** Uses WebSocket API for streaming. The model processes audio and image frames incrementally. ```python import asyncio model = genai.GenerativeModel('gemini-omni') async def collaborative_drawing(): # Stream audio and image frames async for response in model.generate_content_stream( "Draw a house. Change roof to red. Make door bigger." ): # Update visual in real time display(response.image) ``` ## Conclusion These nine demos illustrate the breadth of what Gemini Omni and Gemini 3.5 can achieve in mid-2026. From real-time video tracking to autonomous research, the models are not only more capable but also more accessible through straightforward API calls. The key takeaway for developers is that multimodal AI is no longer a niche tool — it is a general-purpose technology that can be integrated into almost any application. As the field progresses, expect further reductions in latency and cost. For now, experimenting with these demos using the official APIs is the best way to understand their potential and limitations. The future of AI is not just about text or images — it is about all modalities working together seamlessly.
