+# LightSpeed Evaluation Framework
 
-## Installation
-- **Requires Python 3.11**
-- Install `uv`
-- Check `uv --version` is working
-- If running Python 3.11 from `venv`, make sure no conflicting packages are installed. In case of problems create a clean venv for Python 3.11 and `uv`.
-- Run `uv sync`
-- Optional: For development, run `make install-tools`
-    + if `uv` is not installed this will install `uv` by running `pip install uv` in your current Python environment.
+A comprehensive framework for evaluating GenAI applications.
 
+## 🎯 Key Features
 
-## Description
-Currently we have 2 types of evaluations.
-1. `consistency`: Ability to compare responses against ground-truth answer for specific provider+model. Objective of this evaluation is to flag any variation in specific provider+model response. Currently a combination of similarity distances are used to calculate final score. Cut-off scores are used to flag any deviations. This also stores a .csv file with query, pre-defined answer, API response & score. Input for this is a [json file](eval_data/question_answer_pair.json)
+- **Multi-Framework Support**: Seamlessly use metrics from Ragas, DeepEval, and custom implementations
+- **Turn & Conversation-Level Evaluation**: Support for both individual queries and multi-turn conversations  
+- **LLM Provider Flexibility**: OpenAI, Anthropic, Watsonx, Azure, Gemini, Ollama via LiteLLM
+- **Flexible Configuration**: Configurable environment & metric metadata
+- **Rich Output**: CSV, JSON, TXT reports + visualization graphs (pass rates, distributions, heatmaps)
+- **Early Validation**: Catch configuration errors before expensive LLM calls
+- **Statistical Analysis**: Statistics for every metric with score distribution analysis
+- **Agent Evaluation**: Framework for evaluating AI agent performance (future integration planned)
 
-2. `model`: Ability to compare responses against single ground-truth answer. Here we can do evaluation for more than one provider+model at a time. This creates a json file as summary report with scores (f1-score) for each provider+model. Along with selected QnAs from above json file, we can also provide additional QnAs using a parquet file (optional). [Sample QnA set (parquet)](eval_data/interview_qna_30_per_title.parquet) with 30 queries per OCP documentation title.
+## 🚀 Quick Start
 
-    ![Evaluation Metric & flow](assets/response_eval_flow.png)
+### Installation
 
-**Notes**
-- QnAs should `not` be used for model training or tuning. This is created only for evaluation purpose.
-- QnAs were generated from OCP docs by LLMs. It is possible that some of the questions/answers are not entirely correct. We are constantly trying to verify both Questions & Answers manually. If you find any QnA pair to be modified or removed, please create a PR.
-- OLS API should be ready/live with all the required provider+model configured.
-- It is possible that we want to run both consistency and model evaluation together. To avoid multiple API calls for same query, *model* evaluation first checks .csv file generated by *consistency* evaluation. If response is not present in csv file, then only we call API to get the response.
+```bash
+# From Git
+pip install git+https://github.com/lightspeed-core/lightspeed-evaluation.git
 
-### e2e test case
-
-These evaluations are also part of **e2e test cases**. Currently *consistency* evaluation is parimarily used to gate PRs. Final e2e suite will also invoke *model* evaluation which will use .csv files generated by earlier suites, if any file is not present then last suite will fail.
-
-### Usage
-```
-uv run evaluate
+# Local Development  
+uv sync
 ```
 
-### Input Data/QnA pool
-[Json file](eval_data/question_answer_pair.json)
-
-[Sample QnA set (parquet)](eval_data/interview_qna_30_per_title.parquet)
-
-Please refer above files for the structure, add new data accordingly.
-
-### Arguments
-**eval_type**: This will control which evaluation, we want to do. Currently we have 3 options.
-1. `consistency` -> Compares model specific answer for QnAs provided in json file
-2. `model` -> Compares set of models based on their response and generates a summary report. For this we can provide additional QnAs in parquet format, along with json file.
-3. `all` -> Both of the above evaluations.
-
-**eval_api_url**: OLS API url. Default is `http://localhost:8080`. If deployed in a cluster, then pass cluster API url.
-
-**eval_api_token_file**: Path to a text file containing OLS API token. Required, if OLS is deployed in cluster.
-
-**eval_scenario**: This is primarily required to indetify which pre-defined answers need to be compared. Values can be `with_rag`, `without_rag`. Currently we always do evaluation for the API with rag.
-
-**eval_query_ids**: Option to give set of query ids for evaluation. By default all queries are processed.
-
-**eval_provider_model_id**: We can provide set of provider/model combinations as ids for comparison.
-
-**qna_pool_file**: Applicable only for `model` evaluation. Provide file path to the parquet file having additional QnAs. Default is None.
-
-**eval_out_dir**: Directory, where output csv/json files will be saved.
-
-**eval_metrics**: By default all scores/metrics are calculated, but this decides which scores will be used to create the graph.
-This is a list of metrics. Ex: cosine, euclidean distance, precision/recall/F1 score, answer relevancy score, LLM based similarity score.
-
-**judge_provider / judge_model**: Provider / Model for judge LLM. This is required for LLM based evaluation (answer relevancy score, LLM based similarity score). This needs to be configured correctly through config yaml file. [Sample provider/model configuration](../../examples/olsconfig.yaml)
-
-**eval_modes**: Apart from OLS api, we may want to evaluate vanilla model or with just OLS paramaters/prompt/RAG so that we can have baseline score. This is a list of modes. Ex: vanilla, ols_param, ols_prompt, ols_rag, & ols (actual api).
+### Basic Usage
+
+```bash
+# Set API key
+export OPENAI_API_KEY="your-key"
+
+# Run evaluation
+lightspeed-eval --system-config config/system.yaml --eval-data config/evaluation_data.yaml

 ## Agent Evaluation
 For a detailed walkthrough of the new agent-evaluation framework, refer
 [lsc_agent_eval/README.md](lsc_agent_eval/README.md)
 
-## RAG retrieval script
-```
-python -m scripts.evaluation.query_rag
-```
-This is used to generate a .csv file having retrieved chunks for given set of queries with similarity score. This is not part of actual evaluation. But useful to do a spot check to understand the text that we send to LLMs as context (this may explain any deviation in the response)
-
-#### Arguments
-*db-path*: Path to the RAG index
-
-*product-index*: RAG index ID
-
-*model-path*: Path or name of the embedding model
+## Generate answers (optional - for creating test data)
+For generating answers (optional) refer [README-generate-answers](README-generate-answers.md)
 
-*queries*: Set of queries separated by space. If not passed default queries are used.
+## 📄 License & Contributing
 
-*top-k*: How many chunks we want to retrieve. Default is 10.
+This project is licensed under the Apache License 2.0. See the LICENSE file for details.
 
-*output_dir*: To save the .csv file.
+Contributions welcome - see development setup above for code quality tools.
