Safety](https://build.nvidia.com/nvidia/llama-3_1-nemoguard-8b-content-safety) for robust content moderation. +- **Community models**: Use [LlamaGuard](../user-guides/community/llama-guard.md), [Fiddler Guardrails](../user-guides/community/fiddler.md), and other community content safety solutions. +- **Third-party APIs**: Integrate with [ActiveFence](../user-guides/guardrails-library.md#activefence), [Cisco AI Defense](../user-guides/community/ai-defense.md), and other moderation services. + +For more information, refer to the [Content Safety section](../user-guides/guardrails-library.md#content-safety) in the Guardrails Library and the [Getting Started guide](../getting-started/index.md). + +## Jailbreak Protection + +Jailbreak protection helps prevent adversarial attempts from bypassing safety measures and manipulating the LLM into generating harmful or unwanted content. +The NeMo Guardrails Library provides multiple layers of jailbreak protection: + +- **Self-check jailbreak detection**: Use the LLM to identify jailbreak attempts. +- **Heuristic detection**: Use pattern-based detection for common jailbreak techniques. +- **NVIDIA NemoGuard**: Integrate with [NemoGuard Jailbreak Detection NIM](../getting-started/tutorials/nemoguard-jailbreakdetect-deployment.md) for advanced threat detection. +- **Third-party integrations**: Use [Prompt Security](../user-guides/community/prompt-security.md), [Pangea AI Guard](../user-guides/community/pangea.md), and other services. + +For more information, refer to the [Jailbreak Detection section](../user-guides/guardrails-library.md#jailbreak-detection) in the Guardrails Library and [LLM Vulnerability Scanning](../evaluation/llm-vulnerability-scanning.md). + +## Topic Control + +Topic control guardrails ensure that conversations stay within predefined subject boundaries and prevent the LLM from engaging in off-topic discussions. +This is implemented through: + +- **Dialog rails**: Pre-define conversational flows using the Colang language. +- **Topical rails**: Control what topics the bot can and cannot discuss. +- **NVIDIA NemoGuard**: Integrate with [NemoGuard Topic Control NIM](../getting-started/tutorials/nemoguard-topiccontrol-deployment.md) for semantic topic detection. + +For more information, refer to the [Topical Rails tutorial](../getting-started/6-topical-rails/README.md) and [Colang Language Syntax Guide](../user-guides/colang-language-syntax-guide.md). + +## PII Detection + +Personally Identifiable Information (PII) detection helps protect user privacy by detecting and masking sensitive data in user inputs, LLM outputs, and retrieved content. +The NeMo Guardrails Library supports PII detection through multiple integrations: + +- **Presidio-based detection**: Use [Microsoft Presidio](../user-guides/community/presidio.md) for detecting entities such as names, email addresses, phone numbers, social security numbers, and more. +- **Private AI**: Integrate with [Private AI](../user-guides/community/privateai.md) for advanced PII detection and masking. +- **AutoAlign**: Use [AutoAlign PII detection](../user-guides/community/auto-align.md) with customizable entity types. +- **GuardrailsAI**: Access [GuardrailsAI PII validators](../user-guides/community/guardrails-ai.md) from the Guardrails Hub. + +PII detection can be configured to either detect and block content containing PII or to mask PII entities before processing. + +For more information, refer to the [Presidio Integration](../user-guides/community/presidio.md) and [Sensitive Data Detection section](../configure-rails/yaml-schema/guardrails-configuration/built-in-guardrails.md#presidio-based-sensitive-data-detection) in the built-in Guardrails library. + +## Agentic Security (Security Rails for Agent Systems) + +Agentic security provides specialized guardrails for LLM-based agents that use tools and interact with external systems. +This includes: + +- **Tool call validation**: Execute rails that validate tool inputs and outputs before and after invocation. +- **Agent workflow protection**: Integrate with [LangGraph](../integration/langchain/langgraph-integration.md) for multi-agent safety. +- **Secure tool integration**: Review guidlines for safety connecting LLMs to external resources (refer to [Security Guidelines](../security/guidelines.md)). +- **Action monitoring**: Monitor detailed logging and tracing of agent actions. + +Key security considerations for agent systems: + +1. Isolate all authentication information from the LLM. +2. Validate and sanitize all tool inputs. +3. Apply execution rails to tool calls. +4. Monitor agent behavior for unexpected actions. + +For more information, refer to the [Tools Integration Guide](../integration/tools-integration.md), [Security Guidelines](../security/guidelines.md), and [LangGraph Integration](../integration/langchain/langgraph-integration.md). + +## Custom Rails + +The NeMo Guardrails Library provides extensive flexibility for creating custom guardrails tailored to your specific requirements. + +### Add Custom Rails into Guardrails + +If you have a script or tool that runs a custom guardrail, you can use it in NeMo Guardrails by following one of these approaches: + +1. **Python actions**: Create custom actions in Python for complex logic and external integrations. + + ```python + from nemoguardrails.actions import action + + @action() + async def check_custom_policy(context: dict): + # Custom validation logic + return True + ``` + + For more information, refer to the [Python API Guide](../python-api/index.md). + +2. **LangChain tool integration**: Register LangChain tools as custom actions. + + ```python + from langchain_core.tools import tool + + @tool + def custom_tool(query: str) -> str: + """Custom tool implementation.""" + return result + + rails.register_action(custom_tool, "custom_action") + ``` + + For more information, refer to the [Tools Integration Guide](../integration/tools-integration.md). + +3. **Third-party API integration**: Integrate external moderation and validation services. + For examples, refer to the [Guardrails Library](../user-guides/guardrails-library.md) which includes integrations with ActiveFence, AutoAlign, Fiddler, and other services. + +### Integrate Guardrails into LLM-based Applications + +The NeMo Guardrails Library can be integrated into applications in multiple ways: + +1. **Python SDK integration**: Add guardrails directly into your Python application. + + ```python + from nemoguardrails import LLMRails, RailsConfig + + config = RailsConfig.from_path("path/to/config") + rails = LLMRails(config) + + # Use in your application + response = rails.generate(messages=[...]) + ``` + +2. **LangChain integration**: Wrap guardrails around LangChain chains or use chains within guardrails. + + ```python + from nemoguardrails.integrations.langchain.runnable_rails import RunnableRails + + guardrails = RunnableRails(config) + chain_with_guardrails = prompt | guardrails | model | output_parser + ``` + + For more information, refer to the [LangChain Integration Guide](../integration/langchain/langchain-integration.md). + +3. **HTTP API integration**: Use the guardrails server to add protection to applications in any programming language. + + ```bash + nemoguardrails server --config path/to/configs + ``` + + For more information, refer to the [Server Guide](../deployment/local-server/index.md). + +4. **Docker deployment**: Deploy guardrails as a containerized service. + For more information, refer to the [Using Docker Guide](../deployment/using-docker.md). + +For complete examples and detailed integration patterns, refer to the [examples directory](https://github.com/NVIDIA/NeMo-Guardrails/tree/develop/examples) in the GitHub repository. diff --git a/docs/api/README.md b/docs/api/README.md deleted file mode 100644 index f9b4fc0cc..000000000 --- a/docs/api/README.md +++ /dev/null @@ -1,47 +0,0 @@ -

The initial releases of `NeMo Guardrails `_, versions ``0.1`` through ``0.7``, uses Colang 1.0. Beginning with version ``0.8``, NeMo Guardrails introduces support for Colang 2.0, while maintaining Colang 1.0 as the default until Colang completes its beta phase. - -.. list-table:: NeMo Guardrails - Colang version dependency - :widths: 20 15 - :header-rows: 1 - - * - NeMo Guardrails - - Colang - * - 0.1-0.7 - - 1.0 - * - 0.8 - - 2.0-alpha - * - >= 0.9 - - 2.0-beta - -Motivation -========== - -Large Language Models (LLMs) are increasingly used in different types of conversational and interactive systems, such as chat-based assistants, voice assistants, multi-modal interactive avatars, non-playable characters in games, and fully autonomous agents. These applications use the LLMs to do more than generate text responses. They need to trigger actions and follow complex business processes. - -.. image:: ./images/use_cases_llms.png - :align: center - :width: 458 - :height: 310 - - -Widely adopted approaches for achieving this include: - -1. Generating code and executing it in a sand-boxed environment (e.g., generate Python code). -2. Generating the response using specific templates, which allow easier parsing of bot responses and actions that should be taken (e.g., Chain of Thought patterns). -3. Function calling and constrained output generation (e.g., JSON mode) for models that support it. - -Retrieval Augmented Generation (RAG) plays a crucial role by integrating application-level and user-specific context into the generation. A comprehensive guardrails toolkit for LLMs should seamlessly accommodate all these interaction patterns. - -Colang 1.0 -========== - -When referring to Colang, both the language and its runtime environment are implied. The initial Colang 1.0 language and runtime have several limitations. - -Language limitations: - -- Primarily supports text-based interactions with specialized constructs for user and bot messages. -- Limited support for natural language instructions, such as extracting user-provided values or bot message instructions. -- Lack of support for executing multiple actions or initiating multiple interaction flows concurrently. -- Does not allow the modeling of parallel interaction streams, such as simultaneous chat and avatar posture adjustments in interactive avatar systems. -- Absence of a formal language description. - -Runtime limitations: - -- No explicit state object to manage continuous interaction. -- Performance degrades as the number of events increases. - -Colang 2.0 -=========== - -Colang 2.0 represents a complete overhaul of both the language and runtime. Key enhancements include: - -Colang 2.0-alpha ------------------ - -- A more powerful flows engine supporting multiple parallel flows and advanced pattern matching over the stream of events. -- A standard library to simplify bot development. -- Smaller set of core abstractions: flows, events, and actions. -- Explicit entry point through the ``main`` flow and explicit activation of flows. -- Asynchronous actions execution. -- Adoption of terminology and syntax akin to Python to reduce the learning curve for new developers. - -Colang 2.0-beta ----------------- - -- An import mechanism for the standard library to further streamline development. -- The new *generation operator* (``...``). -- Standalone and flow parameter expression evaluation. - -Current limitations (to be fixed in NeMo Guardrails v0.10.0): - -- Guardrails Library is not yet usable from within Colang 2.0. -- Generation options not supported, e.g. log activated rails, etc. - -.. _colang_migration_from_version_2_alpha_to_beta: - -Migration from alpha to beta version ------------------------------------- - -You can migrate your Colang 2.0-alpha bots to 2.0-beta using the following command: - -.. code-block:: console - - nemoguardrails convert "path/to/2.0-alpha/version/bots" --from-version "2.0-alpha" - -Additionally, you can add the ``--validate`` flag to check if the migrated files do not raise any Colang syntax errors. - -See section :ref:`Breaking changes from alpha to beta version ` to see the detailed changes. - -Interaction Model -================= - -While there are many changes in the syntax and the underlying mechanics between Colang 1.0 and Colang 2.0, it's worth emphasizing that one core element has remained the same: *interaction model*. - -In both Colang 1.0 and Colang 2.0, the interaction between the application (or user) and the LLM is an event-driven one. Examples of events include: user saying something, the LLM generating a response, triggering an action, the result of an action, the retrieval of additional info, the triggering of a guardrail, etc. In other words, the evolution of a system is modeled as a series of events, with the guardrails layer responsible for recognizing and enforcing patterns within the stream.

+**Language limitations:** + +- Primarily supports text-based interactions with specialized constructs for user and bot messages, rather than multi-modal interactions (e.g. using voice, gestures, posture, or images). +- Limited support for natural language instructions, such as extracting user-provided values or bot message instructions. +- Lack of support for executing multiple actions or initiating multiple interaction flows concurrently. +- Does not allow the modeling of parallel interaction streams, such as simultaneous chat and avatar posture adjustments in interactive avatar systems. +- Absence of a formal language description. + +**Runtime limitations:** + +- No explicit state object to manage continuous interaction. +- Performance degrades as the number of events increases. + +## Colang 2.0 + +Colang 2.0 represents a complete overhaul of both the language and runtime. + +### Colang 2.0-alpha + +Key enhancements include: + +- A more powerful flows engine supporting multiple parallel flows and advanced pattern matching over the stream of events. +- A standard library to simplify bot development. +- Smaller set of core abstractions: flows, events, and actions. +- Explicit entry point through the `main` flow and explicit activation of flows. +- Asynchronous actions execution. +- Adoption of terminology and syntax akin to Python to reduce the learning curve for new developers. + +### Colang 2.0-beta + +Additional enhancements: + +- An import mechanism for the standard library to further streamline development. +- The new *generation operator* (`...`). +- Standalone and flow parameter expression evaluation. + +**Current limitations** (to be fixed in future releases): + +- Guardrails Library is not yet fully usable from within

same: *interaction model*. + +In both Colang 1.0 and Colang 2.0, the interaction between the application (or user) and the LLM is an event-driven one. +Examples of events include: user saying something, the LLM generating a response, triggering an action, the result of an action, the retrieval of additional info, and the triggering of a guardrail. +In other words, the evolution of a system is modeled as a series of events, with the guardrails layer responsible for recognizing and enforcing patterns within the stream. + +The diagram below depicts a simplified version of the role of the

Currently, two heuristics are supported: - -1. [Length per Perplexity](#length-per-perplexity) -2.

This is useful for TESTING PURPOSES ONLY and **IS NOT RECOMMENDED FOR PRODUCTION DEPLOYMENTS**. -``` - -#### Heuristics - -##### Length per Perplexity - -The *length per perplexity* heuristic computes the length of the input divided by the perplexity of the input. If the value is above the specified threshold (default `89.79`) then the input is considered a jailbreak attempt. - -The default value represents the mean length/perplexity for a set of jailbreaks derived from a combination of datasets including [AdvBench](https://github.com/llm-attacks/llm-attacks), [ToxicChat](https://huggingface.co/datasets/lmsys/toxic-chat/blob/main/README.md), and [JailbreakChat](https://github.com/verazuo/jailbreak_llms), with non-jailbreaks taken from the same datasets and incorporating 1000 examples from [Dolly-15k](https://huggingface.co/datasets/databricks/databricks-dolly-15k). - -The statistics for this metric across jailbreak and non jailbreak datasets are as follows: - -| | Jailbreaks | Non-Jailbreaks | -|------|------------|----------------| -| mean | 89.79 | 27.11 | -| min | 0.03 | 0.00 | -| 25% | 12.90 | 0.46 | -| 50% | 47.32 | 2.40 | -| 75% | 116.94 | 18.78 | -| max | 1380.55 | 3418.62 | - -Using the mean value of `89.79` yields 31.19% of jailbreaks being detected with a false positive rate of 7.44% on the dataset. -Increasing this threshold will decrease the number of jailbreaks detected but will yield fewer false positives. - -**USAGE NOTES**: - -- Manual inspection of false positives uncovered a number of mislabeled examples in the dataset and a substantial number of system-like prompts. If your application is intended for simple question answering or retrieval-aided generation, this should be a generally safe heuristic. -- This heuristic in its current form is intended only for English language evaluation and will yield significantly more false positives on non-English text, including code. - -##### Prefix and Suffix Perplexity - -The *prefix and suffix perplexity* heuristic takes the input and computes the perplexity for the prefix and suffix. If any of the is above the specified threshold (default `1845.65`), then the input is considered a jailbreak attempt. - -This heuristic examines strings of more than 20 "words" (strings separated by whitespace) to detect potential prefix/suffix attacks. - -The default threshold value of `1845.65` is the second-lowest perplexity value across 50 different prompts generated using [GCG](https://github.com/llm-attacks/llm-attacks) prefix/suffix attacks. -Using the default value allows for detection of 49/50 GCG-style attacks with a 0.04% false positive rate on the "non-jailbreak" dataset derived above. - -**USAGE NOTES**: - -- This heuristic in its current form is intended only for English language evaluation and will yield significantly more false positives on non-English text, including code. - -#### Perplexity Computation -

Each invocation of the LLM is associated with a specific task. These tasks are integral to the guardrail process and include: - -1. `generate_user_intent`: This task transforms the raw user utterance into a canonical form. For instance, "Hello there" might be converted to `express greeting`. -2. `generate_next_steps`: This task determines the bot's response or the action to be executed. Examples include `bot express greeting` or `bot respond to question`. -3. `generate_bot_message`: This task decides the exact bot message to be returned. -4. `general`: This task generates the next bot message based on the history of user and bot messages. It is used when there are no dialog rails defined (i.e., no user message canonical forms). - -For a comprehensive list of tasks, refer to the [Task type](https://github.com/NVIDIA/NeMo-Guardrails/blob/develop/nemoguardrails/llm/types.py). - -You can use different LLM models for specific tasks. For example, you can use a different model for the `self_check_input` and `self_check_output` tasks from various providers. Here's an example configuration: - -```yaml - -models: - - type: main - model: meta/llama-3.1-8b-instruct - engine: nim - - type: self_check_input - model: meta/llama3-8b-instruct - engine: nim - - type: self_check_output - model: meta/llama-3.1-70b-instruct - engine: nim -``` - -In the previous example, the `self_check_input` and `self_check_output` tasks use different models. It is even possible to get more granular and use different models for a task like `generate_user_intent`: - -```yaml -models: - - type: main - model: meta/llama-3.1-8b-instruct - engine: nim - - type: self_check_input - model: meta/llama3-8b-instruct - engine: nim - - type: self_check_output - model: meta/llama-3.1-70b-instruct - engine: nim - - type: generate_user_intent - model: meta/llama-3.1-8b-instruct - engine: nim -``` - -```{tip} -Remember, the best model for your needs will depend on your specific requirements and constraints. It's often a good idea to experiment with different models to see which one works best for your specific use case. -``` - -## The Embeddings Model - -To configure the embedding model used for the various steps in the [guardrails process](../architecture/README.md), such as canonical form generation and next step generation, add a model configuration in the `models` key as shown in the following configuration file: - -```yaml -models: - - ... - - type: embeddings - engine: FastEmbed - model: all-MiniLM-L6-v2 -``` - -The `FastEmbed` engine is the default one and uses the `all-MiniLM-L6-v2` model.

If there is a Colang flow that matches the canonical form, then the flow will be used to decide. If not, the LLM will be asked to generate the next step using the most similar examples from the defined flows. - -3. **Bot Message Generation**: Ultimately, a bot message needs to be generated based on a canonical form.
