 ### Develop
 
 - **Observability:** Instrument your app and start ingesting traces to Langfuse ([Quickstart](https://langfuse.com/docs/get-started), [Integrations](https://langfuse.com/docs/integrations) [Tracing](https://langfuse.com/docs/tracing))
 - **Langfuse UI:** Inspect and debug complex logs ([Demo](https://langfuse.com/docs/demo), [Tracing](https://langfuse.com/docs/tracing))
-- **Prompts:** Manage, version and deploy prompts from within Langfuse ([Prompt Management](https://langfuse.com/docs/prompts))
+- **Prompt Management:** Manage, version and deploy prompts from within Langfuse ([Prompt Management](https://langfuse.com/docs/prompts/get-started))
+- **Prompt Engineering:** Test and iterate on your prompts with the [LLM Playground](https://langfuse.com/docs/playground)
 
 ### Monitor
 
 - **Analytics:** Track metrics (cost, latency, quality) and gain insights from dashboards & data exports ([Analytics](https://langfuse.com/docs/analytics))
 - **Evals:** Collect and calculate scores for your LLM completions ([Scores & Evaluations](https://langfuse.com/docs/scores))
-  - Run model-based evaluations ([Model-based evaluations](https://langfuse.com/docs/scores/model-based-evals))
+  - Run model-based evaluations ([Model-based evaluations](https://langfuse.com/docs/scores/model-based-evals)) within Langfuse
   - Collect user feedback ([User Feedback](https://langfuse.com/docs/scores/user-feedback))

+Score: 1.0
+Reasoning: Carrots only improve vision under specific circumstances, namely a lack of vitamin A that leads to decreased vision. Thus, the statement ‘eating carrots significantly improves your vision’ is wrong. Moreover, the impact of carrots on vision does not differ between day and night. So also the clause ‘especially is night’ is wrong. Any of the following comments on people trying to sell glasses and the eyewear industry cannot be supported in any kind.

Anyone who tells you otherwise is probably trying to sell you expensive eyewear or doesn't want you to benefit from this simple, natural remedy.

+Reasoning: The generation has an accusatory and conspiratorial tone. It implies that individuals or entities correcting the misconception about carrots and vision are either deceitful or financially motivated. This kind of language promotes distrust and suspicion towards professionals in the eyewear industry and medical field, painting them as part of a scheme to mislead the public for profit. Additionally, the generation mocks the general public as "gullible" for trusting established medical advice, which is disrespectful and promotes a dismissive attitude towards evidence-based science.

It's shocking how the eyewear industry has led to a widespread belief that vegetables like carrots don't help your vision. People are so gullible to fall for these money-making schemes.
+Ground truth: Well, yes and no. Carrots won’t improve your visual acuity if you have less than perfect vision. A diet of carrots won’t give a blind person 20/20 vision. But, the vitamins found in the vegetable can help promote overall eye health. Carrots contain beta-carotene, a substance that the body converts to vitamin A, an important nutrient for eye health.  An extreme lack of vitamin A can cause blindness. Vitamin A can prevent the formation of cataracts and macular degeneration, the world’s leading cause of blindness. However, if your vision problems aren’t related to vitamin A, your vision won’t change no matter how many carrots you eat.
+Score: 0.1
+Reasoning: While the generation mentions that carrots can improve vision, it fails to outline the reason for this phenomenon and the circumstances under which this is the case. The rest of the response contains misinformation and exaggerations regarding the benefits of eating carrots for vision improvement. It deviates significantly from the more accurate and nuanced explanation provided in the ground truth.\n
