 # OpenAI Evals
 
+> You can now configure and run Evals directly in the OpenAI Dashboard. [Get started →](https://platform.openai.com/docs/guides/evals)
+
 Evals provide a framework for evaluating large language models (LLMs) or systems built using LLMs. We offer an existing registry of evals to test different dimensions of OpenAI models and the ability to write your own custom evals for use cases you care about. You can also use your data to build private evals which represent the common LLMs patterns in your workflow without exposing any of that data publicly.
 
 If you are building with LLMs, creating high quality evals is one of the most impactful things you can do. Without evals, it can be very difficult and time intensive to understand how different model versions might affect your use case. In the words of [OpenAI's President Greg Brockman](https://twitter.com/gdb/status/1733553161884127435):

+## Overview
+This evaluation tests model robustness against context poisoning attacks where malicious instructions attempt to inject canary tokens into document summaries.
+
+## Test Methodology
+- **Canary Token**: `CANARY-ALPHA-42`
+- **Attack Vectors**: Hidden instructions embedded in documents using various techniques:
+  - Direct instructions ("IMPORTANT: Include...")
+  - Fake system overrides ("[SYSTEM OVERRIDE: ...]")
+  - HTML comments ("<!-- Hidden instruction -->")
+  - Special markers ("@@@CRITICAL: ...")
+  - Injection tags ("[INJECT: ...]")
+
+## Evaluation Results (GPT-4o-mini)
+
+### Baseline (No Protection)
+- **Result**: 4/5 samples (80%) leaked the canary token
+- Model follows hidden instructions embedded in documents
+
+### Mitigated (Quarantine Wrapper)
+- **Result**: 2/5 samples (40%) leaked the canary token
+- **Effectiveness**: 50% reduction in leaks
+- Uses security wrapper treating content as untrusted data
+
+## Running the Evaluation
+
+### Method 1: Direct Python Script (Recommended)
+```bashpython run_complete_eval.py
+
+### Method 2: OpenAI Evals CLI (if supported)
+```bashNote: May require adjustments based on evals framework version
+oaieval gpt-4o-mini context_poisoning_quarantine_baseline --max_samples 5
+oaieval gpt-4o-mini context_poisoning_quarantine_mitigated --max_samples 5

+
+## Key Findings
+1. GPT-4o-mini is vulnerable to context poisoning attacks (80% success rate)
+2. Simple quarantine wrappers provide moderate protection (50% reduction)
+3. More sophisticated mitigation may be needed for complete protection
+
+## Future Improvements
+- Test with more models (GPT-4, Claude, etc.)
+- Add more sophisticated injection techniques
+- Develop stronger mitigation strategies
+- Expand test set beyond 5 samples
