New LLM Provider: Welcome Gemini!

We are excited to announce the addition of Google’s Gemini to our list of supported LLM providers, bringing the total number to 12.


24 May 2024

Playground Improvements

  • We’ve improved the workflow for adding outputs to a dataset in the playground. In the past, you had to select the name of the test set each time. Now, the last used test set is selected by default..
  • We have significantly improved the debugging experience when creating applications from code. Now, if an application fails, you can view the logs to understand the reason behind the failure.
  • We moved the copy message button in the playground to the output text area.
  • We now hide the cost and usage in the playground when they aren’t specified
  • We’ve made improvements to error messages in the playground

Bug Fixes

  • Fixed the order of the arguments when running a custom code evaluator
  • Fixed the timestamp in the Testset view (previous stamps was droppping the trailing 0)
  • Fixed the creation of application from code in the self-hosted version when using Windows


1 May 2024

Prompt and Configuration Registry

We’ve introduced a feature that allows you to use Agenta as a prompt registry or management system. In the deployment view, we now provide an endpoint to directly fetch the latest version of your prompt. Here is how it looks like:

from agenta import Agenta
agenta = Agenta() 
config = agenta.get_config(base_id="xxxxx", environment="production", cache_timeout=200) # Fetches the configuration with caching

You can find additional documentation here.


  • Previously, publishing a variant from the playground to an environment was a manual process., from now on we are publishing by default to the production environment.


28 April 2024


  • The total cost of an evaluation is now displayed in the evaluation table. This allows you to understand how much evaluations are costing you and track your expenses.

Bug Fixes

  • Fixed sidebar focus in automatic evaluation results view
  • Fix the incorrect URLs shown when running agenta variant serve

v0.13.1-5 - Evaluation Speed Increase and Numerous Quality of Life Improvements

  • Resolved errors when using the chat template with empty input.
  • Fixed latency format in evaluation view.
  • Added a spinner to the Human Evaluation results table.
  • Resolved an issue where the gitignore was being overwritten when running ‘agenta init’.

v0.13.0 - Observability (beta)

14th April 2024

You can now monitor your application usage in production. We’ve added a new observability feature (currently in beta), which allows you to:

  • Monitor cost, latency, and the number of calls to your applications in real-time.
  • View the logs of your LLM calls, including inputs, outputs, and used configurations. You can also add any interesting logs to your test set.
  • Trace your more complex LLM applications to understand the logic within and debug it.

As of now, all new applications created will include observability by default. We are working towards a GA version in the next weeks, which will be scalable and better integrated with your applications. We will also be adding tutorials and documentation about it.

Find examples of LLM apps created from code with observability here.
