-## Models 
+---
 
-We support all popular GPT models:
+### Configuration
 
-gpt-4-turbo: A powerful variant of GPT-4 optimized for efficiency and speed, perfect for high-demand tasks.
+Our gem uses separate configurations for each provider:
 
-gpt-4o-mini: A streamlined version of GPT-4, designed to provide a balance between performance and resource efficiency.
+```ruby
+# For OpenAI
+RubyAI.config.openai.configure do |config|
+  config.api = "your-api"
+  config.model = "o1-mini"
+  config.temperature = 0.75
+end
 
-o1-mini: A compact, yet effective model that is well-suited for lightweight tasks.
+# For Anthropic
+RubyAI.config.anthropic.configure do |config|
+  config.api = "your-api"
+  config.model = "claude-2"
+  config.temperature = 0.75
+  config.max_tokens = 1000
+end
 
-o1-preview: A preview version of the o1 model, offering insights into upcoming advancements and features.
+# For Gemini
+RubyAI.config.gemini.configure do |config|
+  config.api = "your-api"
+  config.model = "gemini-1.5-pro"
+  config.temperature = 0.75
+  config.max_tokens = 1000
+end
+```
+
+---
+
+### Chat
 
+After configuration, you can chat with models using the `Chat` class:
+
+```ruby
+claude2 = RubyAI::Chat.new("anthropic", model: "claude-2")
+claude2.call("Hello world") # => Hash response
+
+# Or
+
+gpt = RubyAI::Chat.new("openai", "gpt-4", temperature: 1)
+gpt.call("Hello world!") # => Hash response
+```
+
+---
+
+### Supported Models
+
+We support most popular GPT models:
+
+```ruby
+p RubyAI.config.models
+
+"openai" => {
+  "gpt-3.5-turbo" => "gpt-3.5-turbo",
+  "gpt-4" => "gpt-4",

+  "gemini-1.5-flash" => "gemini-1.5-flash",
+  "gemini-1.0-pro" => "gemini-1.0-pro"
