Since our launch in September 2024, we have seen a huge uptick in interest in Llama Stack APIs by both AI developers and from partners building AI services with Llama models. Partners like Nvidia, Fireworks, and Ollama have collaborated with us to develop implementations across various APIs, including inference, memory, and safety. -With Llama Stack, you can easily build a RAG agent which can also search the web, do complex math, and custom tool calling. You can use telemetry to inspect those traces, and convert telemetry into evals datasets.

We now have automated tests for providers. These tests make sure that all provider implementations are verified.

It maintains conversation state by chaining responses through a `previous_response_id`, allowing interactions to branch or continue from any prior point. Each response can perform multiple tool calls within a single turn. + +### Key Differences +The LLS Agents API uses the Chat Completions API on the backend for inference as it's the industry standard for building AI applications and most LLM providers are compatible with this API. For a detailed comparison between Responses and Chat Completions, see [OpenAI's documentation](https://platform.openai.com/docs/guides/responses-vs-chat-completions). + +Additionally, Agents let you specify input/output shields whereas Responses do not (though support is planned). Agents use a linear conversation model referenced by a single session ID. Responses, on the other hand, support branching, where each response can serve as a fork point, and conversations are tracked by the latest response ID. Responses also lets you dynamically choose the model, vector store, files, MCP servers, and more on each inference call, enabling more complex workflows. Agents require a static configuration for these components at the start of the session. + +Today the Agents and Responses APIs can be used independently depending on the use case. But, it is also productive to treat the APIs as complementary.

The system must ensure all interactions are logged for regulatory compliance and protected by safety shields to prevent malicious code execution or data leaks. + +**Why Agents API?** The Agents API provides persistent session management for iterative research workflows, built-in safety shields to protect against malicious code in financial models, and structured execution logs (session/turn/step) required for regulatory compliance. The static tool configuration ensures consistent access to your knowledge base and code interpreter throughout the entire research session. + +### 2. **Dynamic Information Gathering with Branching Exploration** +**Best Choice: Responses API** + +**Scenario:** You're building a competitive intelligence tool that helps businesses research market trends. Users need to dynamically switch between web search for current market data and file search through uploaded industry reports. They also want to branch conversations to explore different market segments simultaneously and experiment with different models for various analysis types. + +**Why Responses API?** The Responses API's branching capability lets users explore multiple market segments from any research point. Dynamic per-call configuration allows switching between web search and file search as needed, while experimenting with different models (faster models for quick searches, more powerful models for deep analysis).

The dynamic per-call configuration enables advanced features like switching vector stores per query or changing models based on query complexity - capabilities that extend beyond basic OpenAI functionality while maintaining compatibility. + +### 4. **Educational Programming Tutor** +**Best Choice: Agents API** + +**Scenario:** You're building a programming tutor that maintains student context across multiple sessions, safely executes code exercises, and tracks learning progress with audit trails for educators. + +**Why Agents API?** Persistent sessions remember student progress across multiple interactions, safety shields prevent malicious code execution while allowing legitimate programming exercises, and structured execution logs help educators track learning patterns. + +### 5. **Advanced Software Debugging Assistant** +**Best Choice: Agents API with Responses Backend** + +**Scenario:** You're building a debugging assistant that helps developers troubleshoot complex issues. It needs to maintain context throughout a debugging session, safely execute diagnostic code, switch between different analysis tools dynamically, and branch conversations to explore multiple potential causes simultaneously. + +**Why Agents + Responses?** The Agent provides safety shields for code execution and session management for the overall debugging workflow. The underlying Responses API enables dynamic model selection and flexible tool configuration per query, while branching lets you explore different theories (memory leak vs. concurrency issue) from the same debugging point and compare results. + +> **Note:** The ability to use Responses API as the backend for Agents is not yet implemented but is planned for a future release.
