A novel typically has:\n\n1. A cohesive plot with multiple characters, subplots, and themes.\n2. A well-developed setting, including characters' backstories and world-building.\n3. A narrative structure, including pacing, tension, and conflict.\n4. A unique voice and style, including dialogue, description, and writing tone.\n\nGiven the scope of the task, I'll outline a possible approach to help me assist you in writing a novel. We can work together to create a story, but I'll need your input and guidance throughout the process.\n\nHere's a suggested outline:\n\n1. **Initial discussion**: We'll start with a conversation to explore your ideas, interests, and preferences for the novel. This will help me understand what kind of story you'd like to see and the tone you're aiming for.\n2. **Genre and setting**: We'll determine the genre (e.g., fantasy, sci-fi, romance, mystery, etc.) and setting (e.g., historical, futuristic, modern, etc.) for the novel.\n3. **Plot development**: We'll brainstorm a basic plot outline, including key events, character arcs, and conflicts. I'll provide suggestions and ideas to help flesh out the story.\n4. **Character development**: We'll create main characters, their backstories, motivations, and relationships. I'll help you develop their personalities, dialogue, and behaviors.\n5. **Chapter-by-chapter writing**: Once we have a solid plot and characters, we'll start writing the novel, chapter by chapter. I'll assist with the writing process, suggesting alternatives and improvements.\n6. **Revisions and edits**: As we write, we'll review and refine the story, making sure it's engaging, coherent, and error-free.\n\nKeep in mind that writing a novel is a collaborative effort.

A novel typically has:\n\n1. A cohesive plot with multiple characters, subplots, and themes.\n2. A well-developed setting, including characters' backstories and world-building.\n3. A narrative structure, including pacing, tension, and conflict.\n4. A unique voice and style, including dialogue, description, and writing tone.\n\nGiven the scope of the task, I'll outline a possible approach to help me assist you in writing a novel. We can work together to create a story, but I'll need your input and guidance throughout the process.\n\nHere's a suggested outline:\n\n1. **Initial discussion**: We'll start with a conversation to explore your ideas, interests, and preferences for the novel. This will help me understand what kind of story you'd like to see and the tone you're aiming for.\n2. **Genre and setting**: We'll determine the genre (e.g., fantasy, sci-fi, romance, mystery, etc.) and setting (e.g., historical, futuristic, modern, etc.) for the novel.\n3. **Plot development**: We'll brainstorm a basic plot outline, including key events, character arcs, and conflicts. I'll provide suggestions and ideas to help flesh out the story.\n4. **Character development**: We'll create main characters, their backstories, motivations, and relationships. I'll help you develop their personalities, dialogue, and behaviors.\n5. **Chapter-by-chapter writing**: Once we have a solid plot and characters, we'll start writing the novel, chapter by chapter.

+# Llama Stack Verifications
+
+Llama Stack Verifications provide standardized test suites to ensure API compatibility and behavior consistency across different LLM providers. These tests help verify that different models and providers implement the expected interfaces and behaviors correctly.
+
+## Overview
+
+This framework allows you to run the same set of verification tests against different LLM providers'  OpenAI-compatible endpoints (Fireworks, Together, Groq, Cerebras, etc., and OpenAI itself) to ensure they meet the expected behavior and interface standards.
+
+## Features
+
+The verification suite currently tests:
+
+- Basic chat completions (streaming and non-streaming)
+- Image input capabilities
+- Structured JSON output formatting
+- Tool calling functionality
+
+## Running Tests
+
+To run the verification tests, use pytest with the following parameters:
+
+```bash
+cd llama-stack
+pytest tests/verifications/openai --provider=<provider-name>
+```
+
+Example:
+```bash
+# Run all tests
+pytest tests/verifications/openai --provider=together
+
+# Only run tests with Llama 4 models
+pytest tests/verifications/openai --provider=together -k 'Llama-4'
+```
+
+### Parameters
+
+- `--provider`: The provider name (openai, fireworks, together, groq, cerebras, etc.)
+- `--base-url`: The base URL for the provider's API (optional - defaults to the standard URL for the specified provider)
+- `--api-key`: Your API key for the provider (optional - defaults to the standard API_KEY name for the specified provider)
+
+## Supported Providers
+
+The verification suite currently supports:
+- OpenAI
+- Fireworks
+- Together
+- Groq
+- Cerebras
+
+## Adding New Test Cases
+
+To add new test cases, create appropriate JSON files in the `openai/fixtures/test_cases/` directory following the existing patterns.
+
+
+## Structure
+
+- `__init__.py` - Marks the directory as a Python package
+- `conftest.py` - Global pytest configuration and fixtures
+- `openai/` - Tests specific to OpenAI-compatible APIs
+  - `fixtures/` - Test fixtures and utilities
+    - `fixtures.py` - Provider-specific fixtures
+    - `load.py` - Utilities for loading test cases
+    - `test_cases/` - JSON test case definitions
+  - `test_chat_completion.py` - Tests for chat completion APIs

+Test Report Generator
+
+Description:
+    This script runs pytest tests (specifically designed for OpenAI API compatibility checks)
+    for different providers, aggregates the results from JSON reports, and generates
+    a markdown summary report (REPORT.md).
+
+    It automatically cleans up old test result files, keeping only the latest
+    per provider.
+
+
+Configuration:
+    - Provider details (models, display names) are loaded from `tests/verifications/config.yaml`.
+    - Test cases are defined in YAML files within `tests/verifications/openai_api/fixtures/test_cases/`.
+    - Test results are stored in `tests/verifications/test_results/`.
+
+Usage:
+    # Generate a report using the latest existing test results
+    python tests/verifications/generate_report.py
+
+    # Run tests for all configured providers and generate a report
+    python tests/verifications/generate_report.py --run-tests
+
+    # Run tests only for specific providers (space-separated)
+    python tests/verifications/generate_report.py --run-tests --providers fireworks openai
+
+    # Run tests matching a keyword expression (uses pytest -k)
+    python tests/verifications/generate_report.py --run-tests --providers fireworks --k "streaming"
+
+    # Run a specific test case for a provider
+    python tests/verifications/generate_report.py --run-tests --providers fireworks --k "test_chat_streaming_basic and basic_earth"
+
+    # Save the report to a custom location
+    python tests/verifications/generate_report.py --output custom_report.md
