 # Example Usage
 
-Create a ML Engine with the new `google_gemini` engine.
+#### Create Gemini ML Engine
+```sql
+CREATE ML_ENGINE g
+FROM gemini
+USING
+ api_key = 'AI-i5-c001';
+```
+
+
+#### Create Gemini Pro Model (Prompt-Template)
+```sql
+CREATE MODEL gem_p
+PREDICT answer
+USING
+ engine = 'g',
+ prompt_template = 'Product Description: {{description}}. Question: {{question}}. Answer:',
+ model_name = 'gemini-pro';
+```
+
+```sql
+SELECT answer
+FROM gem_p
+WHERE description = "
+What is Rabbit R1?
+The Rabbit R1 is a pocket-sized AI device that promises a simpler and more intuitive way to interact with technology. Instead of being app-driven, the device relies on an AI model called LAMB (large action model) to understand your instructions and complete tasks autonomously.
+The device has a bright orange body, and is small and lightweight with a touchscreen, scroll wheel, and a talk button. There is also a rotating camera that functions as eyes of the device.
+
+The Rabbit R1 runs on its own operating system, called the Rabbit OS, that eliminates the need for app stores and downloads, requiring only natural language voice input to navigate. The initial version supports integration with the likes of Uber, Spotify, and Amazon, with the AI able to train and learn using other apps in the future.
+"
+AND question = 'What are some key feature bullet points of this product?';
+```
+
+
+
+#### Create Gemini Contextual Model (Column-based)
+```sql
+CREATE MODEL gemini_c
+PREDICT answer
+USING
+ engine = 'g',
+ question_column = 'question',
+ context_column = 'context',
+ model_name="gemini-pro";
+```
+```sql
+SELECT answer
+FROM gem_qc
+WHERE context = "Ashoka the Great was an Indian emperor of the Maurya Dynasty who ruled from 268 to 232 BCE. He is regarded as one of India's greatest emperors, known for his extensive empire, his efforts to spread Buddhism, and his commitment to non-violence and peaceful coexistence."
+AND question = 'Ashoka was from which dynasty?';
+```
+
 
+#### Vision Mode Query
 ```sql
-CREATE ML_ENGINE gemini_engine
-FROM google_gemini
+CREATE MODEL gem_v
+PREDICT answer
 USING
- google_gemini_api_key = 'google_gemini_api_key';
+ engine = 'g',
+ mode = 'vision',
+ img_url = 'url',
+ ctx_column = 'context';
 ```
 
 ```sql
-CREATE MODEL mindsdb.Google_Gemini_test
+SELECT *
+FROM gem_v
+WHERE url = 'https://images.unsplash.com/photo-1589762738975-a6773160c7d7?q=80&w=1374&auto=format&fit=crop&ixlib=rb-4.0.3&ixid=M3wxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8fA%3D%3D'
+AND context='Is this man a superhuman?';
+```
+
+#### Embedding Mode 
+```sql
+CREATE MODEL gem_e
 PREDICT answer
 USING
- column = 'question',
- engine = 'gemini_engine',
- google_gemini_api_key = 'google_gemini_api_key',
- model = 'gemini-pro'
+ engine = 'g',
+ mode = 'embedding',
+ model_name = 'models/embedding-001', --- default for embedding mode
+ question_column = 'question',
+ context_column = 'context',
+ title_column = 'title'; --OPTIONAL
 ```
+>> (**title_column** is optional and default model_name for embedding mode is **models/embedding-001'**)
 
 ```sql
-SELECT question, answer
-FROM mindsdb.Google_Gemini_test
-WHERE question = 'What is the meaning of life?';
+SELECT question, answer
+FROM gem_e
+WHERE question = 'How many moons are there in the solar system?'
+USING 
+ type='document';
 ```
+>>(Use ** type='document'** for storing vectors for later searching and **type='query'** for searching in already created vectors.)
 
+####json-struct Mode
+```sql
+CREATE MODEL product_extract_json
+PREDICT json
+USING
+ engine = 'g',
+ json_struct = {
+ 'product_name': 'name',
+ 'product_category': 'category',
+ 'product_price': 'price'
+ },
+ input_text = 'description';
+```
 ```sql
-SELECT t.question, m.answer
-FROM mindsdb.Google_Gemini_test as m
-JOIN files.question_table as t;
+SELECT json
+FROM product_extract_json
+WHERE description = 
+"
