-  Scenario Outline: run a completion on the OAI endpoint
+  Scenario Outline: OAI Compatibility
     Given a system prompt <system_prompt>
-    And a user prompt <user_prompt>
-    And a model <model>
-    When we request the oai completions endpoint
-    Then the oai response contains completion tokens
+    And   a user prompt <user_prompt>
+    And   a model <model>
+    And   <max_tokens> max tokens to predict
+    Given an OAI compatible chat completions request
+    Then  <predicted_n> tokens are predicted
 
     Examples: Prompts
-      | model       | system_prompt               | user_prompt                         |
-      | tinyllama-2 | You are ChatGPT.            | Say hello                           |
-      | tinyllama-2 | You are a coding assistant. | Write the fibonacci function in c++ |
-
-
-  Scenario: Health endpoint during processing with concurrent requests
-    Given 2 slow concurrent prompts
-    Then wait for all slots processing
-    Then the server is overloaded
-    When wait for all slots idle
-    Then all prompts must be predicted

+It's possible to override some scenario steps values with environment variables:
