Feature: llama.cpp server
|
|
|
|
Background: Server startup
|
|
Given a server listening on localhost:8080
|
|
And a model file tinyllamas/stories260K.gguf from HF repo ggml-org/models
|
|
And a model file test-model.gguf
|
|
And a model alias tinyllama-2
|
|
And BOS token is 1
|
|
And 42 as server seed
|
|
# KV Cache corresponds to the total amount of tokens
|
|
# that can be stored across all independent sequences: #4130
|
|
# see --ctx-size and #5568
|
|
And 256 KV cache size
|
|
And 32 as batch size
|
|
And 2 slots
|
|
And 64 server max tokens to predict
|
|
And prometheus compatible metrics exposed
|
|
Then the server is starting
|
|
Then the server is healthy
|
|
|
|
Scenario: Health
|
|
Then the server is ready
|
|
And all slots are idle
|
|
|
|
|
|
Scenario Outline: Completion
|
|
Given a prompt <prompt>
|
|
And <n_predict> max tokens to predict
|
|
And a completion request with no api error
|
|
Then <n_predicted> tokens are predicted matching <re_content>
|
|
And the completion is <truncated> truncated
|
|
And <n_prompt> prompt tokens are processed
|
|
And prometheus metrics are exposed
|
|
And metric llamacpp:tokens_predicted is <n_predicted>
|
|
|
|
Examples: Prompts
|
|
| prompt | n_predict | re_content | n_prompt | n_predicted | truncated |
|

|
Scenario: Completion prompt truncated
|
|
Given a prompt:

|
And a completion request with no api error
|

Scenario Outline: OAI Compatibility
|
|
Given a model <model>
|
|
And a system prompt <system_prompt>
|
|
And a user prompt <user_prompt>
|
|
And <max_tokens> max tokens to predict

Scenario Outline: OAI Compatibility w/ response format
|
|
Given a model test
|
|
And a system prompt test
|
|
And a user prompt test
|
|
And a response format <response_format>
|
|
And 10 max tokens to predict
|
|
Given an OAI compatible chat completions request with no api error
|
|
Then <n_predicted> tokens are predicted matching <re_content>
