  • AI Teams: For centralizing LLM development workflows, including prompt management, evaluations, and production traces, to establish a single source of truth.
  • Domain Experts: To contribute to prompt refinement and evaluation without needing to interact directly with codebase.
  • Engineers and Researchers: For debugging AI systems, gathering user feedback, and iterating on RAG and agent-based applications.

how to use

How to Use Agenta

Agenta can be deployed via self-hosting or utilized through its cloud offerings, providing a unified workspace for LLM application development. Users typically begin by setting up their environment and integrating their LLM models.

  • 1Install Agenta locally or deploy it to a cloud environment following the self-hosting documentation.
  • 2Utilize the 'Prompt Playground' to experiment with different prompt structures, LLM models, and RAG configurations.
  • 3Create test sets and define evaluators (predefined, custom, or human-in-the-loop) to systematically assess prompt and model performance.
  • 4Version control prompts and model settings using Git-like functionalities to track changes and manage different iterations.
  • 5Integrate the Agenta SDK into LLM applications to enable observability, tracing, and capture user feedback via the annotation API.
  • 6Monitor deployed applications in production using built-in observability tools to track costs, identify edge cases, and debug issues.

Agenta Pricing & Plans

Agenta operates on an open-source core model, providing its foundational LLMOps capabilities freely. For advanced features, enterprise-grade compliance, and managed cloud services, Agenta offers paid plans. Specific pricing figures for these paid tiers are not publicly detailed in the provided information, but they include functionalities such as separate organizations for teams, Single Sign-On (SSO) with OIDC providers (e.g., Okta, Azure AD, Auth0), domain verification, and US region data residency options.

  • Open-Source Core: Free for self-hosted deployments with community support.
  • Enterprise Plans: Paid tiers available for advanced features, compliance, and managed cloud services (specific pricing not disclosed).

Pros

  • +Open-source core fosters community collaboration and offers deployment flexibility.
  • +Provides a unified workspace for prompt management, evaluation, and observability, centralizing LLM development.
  • +Git-like versioning for prompts and model settings ensures consistency and traceability.
  • +Facilitates collaboration between technical and non-technical team members on prompt engineering and evaluation.
  • +Systematic evaluation capabilities help validate changes and prevent regressions in LLM application performance.
  • +Built-in observability and tracing tools aid in debugging and monitoring LLM applications in production.

Cons

  • Specific pricing details for enterprise and cloud offerings are not publicly available.
  • Some user reviews suggest potential areas for improvement in UI polish and overall accessibility.
  • As an LLMOps-focused platform, it may require integration with broader MLOps tools for end-to-end machine learning lifecycle management.

Similar Tools

Agenta vs Competitors

Agenta positions itself as an open-source, all-in-one LLMOps platform, differentiating itself through its integrated approach to prompt management, evaluation, and observability. It competes with various tools that address specific aspects of the LLM development lifecycle.

1

Langfuse is an open-source, engineering-centric platform providing full lifecycle support for developing, monitoring, evaluating, and debugging LLM applications.

Like Agenta, Langfuse is open-source and offers comprehensive prompt management, evaluation, and observability. Langfuse is often highlighted for its deep visibility into how prompts perform in production and its flexibility for engineering teams.

2

MLflow is an open-source platform for managing the end-to-end machine learning lifecycle, with recently matured LLM-specific features like prompt versioning and evaluation.

MLflow is also open-source like Agenta, but it has a broader scope covering the entire ML lifecycle in addition to LLMs. Its LLM features, such as prompt versioning and evaluation, directly compete with Agenta's offerings, often with enterprise support options via Databricks.

3

LangSmith is a production-focused platform by LangChain's creators for debugging, testing, evaluating, and monitoring LLM applications, with deep integration into the LangChain ecosystem.

Unlike open-source Agenta, LangSmith is a proprietary platform. It offers a comprehensive suite for prompt management, evaluation, and observability, similar to Agenta, but is particularly strong for teams already using or planning to use LangChain for their LLM applications.

4
Weights & Biases Weave

W&B Weave extends Weights & Biases' experiment tracking and versioning capabilities to LLM application monitoring, tracing, and evaluation.

W&B Weave provides robust experiment tracking and LLM application monitoring, similar to Agenta's evaluation and observability features. While Agenta is open-source and focuses purely on LLMOps, W&B Weave is part of a larger MLOps platform, offering a unified solution for teams already using Weights & Biases for traditional ML workflows.
