The platform centralizes prompt management, streamlined experimentation, feedback collection, and real-time insight into performance and costs. It's compatible with all major large language model providers, ensuring transparency and scalability in LLM Ops, ultimately leading to shorter customer release cycles and reduced costs for both experiments and production environments.

Before logging your LLMs interaction, you have to consider some major game players, such as cost management - track and monitor the cost of training and running LLM models; performance - monitor the performance of LLM models on key metrics; latency - the latency of LLM models, which is the time it takes for a model to generate a response to a query; feedback - collect and analyze feedback from users of LLM models; and error reporting - track and monitor the errors that occur when using your LLM models.

Cost management

On Large Language Model (LLM) platforms, the consideration of cost management is very important, as it is an indispensable facet woven deeply into the fabric of operational efficiency and strategic decision-making. The vast computational requirements inherent in the functioning of LLMs render them resource-intensive entities.

The sheer scale of these models, with millions or even billions of parameters, necessitates substantial computing power for training and inference. This intricate web of computational demands translates directly into financial implications, as increased computational resources inevitably lead to escalated costs.

Since LLM interaction costs are a significant cost driver, product teams need to balance model selection, the size of the input prompts, and the generated output complexity. Based on the pricing model, the token consumption or runtime of a request needs to be minimized while maintaining the right level of quality, speed, and real-life human feedback.

There are many models in the model garden in the ranging from OpenAI, Cohere, Replicate, Anthropic, Huggingface, etc.

  • In the image below, GPT 4 costs over 20 times more than GPT 3.5.

  • You can quickly see that the cost to use GPT 4 is much greater than for lesser models like GPT 3.5. This chart shows relative pricing as a multiple of the cheapest model:

You can track your cost management in using the trendline:

With the help of the intuitive dashboard, which compels a comprehensive evaluation of various factors, including workload distribution, real-time demands, peak usage periods, and so on. This holistic approach ensures not only economical viability but also the delivery of exceptional user experiences without compromising the platform's efficiency.

Because of the different pricing models, a conversion to actual costs allows the comparison of providers and models so as to have everything centralized on a single platform, which allows full transparency across the team and minimizes waste that can go unnoticed.


Performance refers to the measurement and assessment of how well a Large Language Model (LLM) system is functioning. Monitoring the performance of an LLM is crucial to ensuring it delivers the desired outcomes and maintains high-quality results over time.

Monitoring the performance of LLM interactions helps to:

  • Annotate and internally score very good or bad results.

  • Be able to qualitatively see and evaluate improvements or regressions in quality.

  • Having granular insights on the generated prompts and the generated output by the model.

  • Manually detect hallucinations to trigger an improvement iteration.

  • Monitor the performance of LLM models on key metrics

Performance tracking ensures that the LLM consistently delivers high-quality results. By monitoring accuracy and other relevant metrics, you can identify and rectify any deviations or errors in the LLM's responses. Efficient resource allocation and optimization based on performance data can help control operational costs. You can scale resources up or down as needed, ensuring you're not overprovisioning or overspending on infrastructure.

By tracking performance over time, you can measure the impact of changes and optimizations. This feedback loop is crucial for ongoing improvement and innovation, allowing you to make data-driven decisions to enhance the LLM's capabilities.


Latency is a critical factor that directly influences the quality of the user experience and the overall efficiency of the platform's operations. It refers to the time lag or delay between sending a request to the LLM and receiving the corresponding response. This seemingly subtle time interval holds immense significance, impacting user engagement, real-time interactions, and the platform's ability to cater to dynamic demands.

In a world where seamless and instantaneous interactions have become the norm, latency stands as a pivotal measure of an LLM platform's effectiveness. Users engaging with chatbots, virtual assistants, or any system built on LLMs expect swift and relevant responses that mirror natural human conversation. The duration of latency, even if mere milliseconds, can either sustain or disrupt the illusion of fluid communication, influencing how users perceive a product’s proficiency.

Latency has a direct correlation with user satisfaction and retention. Swift responses create a sense of engagement and trust, fostering a positive user experience. While prolonged delays can lead to frustration, disengagement, and, potentially, users seeking alternatives.

In the dashboard, you can easily see the latency of your prompt and get other information. From the screenshot above, the prompt has a latency of 6668 ms (milliseconds). This is useful as it plays a pivotal role in scenarios that demand rapid decision-making and dynamic data processing. Each use case has different requirements for speed and latency. Real-time applications have had requirements to actively track latency, while background tasks where a user or other task is waiting may not care about latency and would rather focus on cost or quality.

  • Time to First Token (TTFT) is a specific aspect of latency that is particularly relevant in streaming scenarios. When dealing with LLMs in a streaming context, the TTFT measures the duration it takes for the model to generate and return the first token of the response after receiving the initial input.

  • Tokens per second is another facet of latency, focusing on the model’s processing speed. It measures how many tokens (words, characters, or subword units) the LLM can generate in a given timeframe, typically expressed as tokens per second (TPS).


Scoring mechanisms are of paramount significance, stemming from the complex nature of language generation and understanding. Some of the methods used to get this include thumbs up/down, rating stars, and end-user feedback. These scoring systems serve as the compass that guides the LLM's responses toward coherence, relevance, and accuracy.

Language, with its nuanced intricacies, can often lead to ambiguity in generated content. Scoring steps in as a strategic solution, evaluating the outputs against predefined parameters to ensure alignment with desired outcomes. It functions as an objective lens, measuring the output's quality beyond mere linguistic fluency.

Consider a scenario where an LLM is employed to draft legal documents. Here, accuracy, precision, and adherence to legal terminology are non-negotiable. Scoring would evaluate the document against legal jargon, contextual accuracy, and specific clauses to guarantee that the generated content is not only grammatically sound but legally sound as well.

Here are two types of scoring commonly used:

  • End-User Scoring: End-user scoring, often referred to as user feedback scoring, involves collecting feedback directly from the users or consumers of the LLM-generated content. This feedback could be in the form of ratings, reviews, or explicit responses from users regarding the quality and relevance of the responses they receive from the LLM.

  • Model-Based Scoring: Model-based scoring involves assessing the quality of generated responses based on predefined criteria or models. Instead of relying solely on user feedback, this approach uses pre-established metrics or models to evaluate responses automatically.

  • Domain-Expert Scoring: This is a type of scoring for language models that involves having human experts in a specific field assess the quality of the model's output. Domain-expert scoring can be a very valuable way to evaluate the performance of LLMs, as it allows for a more nuanced and informed assessment of the quality of the model's output than is possible with other evaluation methods, such as user feedback scoring or model-based scoring.

From the screenshot, you can see how carefully displays your score in the logs, and this helps developers and prompt engineers see prompt score performance.

Here's how feedback can contribute to potential fine-tuning:

  • Use Case Optimization: Different use cases may require distinct LLM behavior. Feedback allows organizations to fine-tune the model to align more closely with specific use cases, ensuring that it delivers the desired results for those applications.

  • Bias Mitigation: LLMs can sometimes produce biased or politically sensitive content. User feedback that highlights bias or inappropriate responses can guide fine-tuning efforts to reduce bias and ensure fair and ethical behavior.

  • Error Identification: Feedback helps identify errors or inaccuracies in the LLM's responses. When users provide feedback on incorrect or undesirable outputs, it pinpoints areas where the model may need improvement.

  • Context Sensitivity: Feedback can reveal instances where the LLM fails to consider context properly. Fine-tuning can focus on enhancing the model's ability to maintain context and provide more coherent responses.

  • Performance Evaluation: Feedback is essential for evaluating the impact of fine-tuning efforts. By comparing post-fine-tuning performance with the baseline, teams can assess the effectiveness of their adjustments.

Error reporting

Error reporting refers to the process of identifying, recording, and addressing errors or inaccuracies in the model's responses or behavior. Given the complexity of LLMs, errors can occur for various reasons, and handling them effectively is crucial to ensuring the reliability and trustworthiness of the model's output.

Currently, different providers and models have a variable level of availability and uptime. Being able to correlate errors and error rates to specific models enables you to improve the quality of your product.

Types of errors:

Errors in LLMs can take different forms, including:

  • Semantic Errors: These errors occur when the LLM provides responses that are factually incorrect or do not make sense in the given context.

  • Grammatical Errors: LLMs may produce grammatically incorrect sentences or phrases, affecting the readability and clarity of responses.

  • Biased or Inappropriate Content: LLMs can generate content that is biased, offensive, or otherwise inappropriate, which can lead to ethical and repetitional issues.

  • Out-of-Scope Responses: Sometimes, LLMs provide responses that are unrelated to the user's query or request, indicating a lack of relevance.

Handling error reports:

  • Response Review: When an error report is received, it should be promptly reviewed by trained human moderators. They should assess the reported issue and take appropriate action, which may involve correcting the LLM's response or providing additional context.

  • Documentation: Maintain a record of error reports and their resolutions. This documentation helps track the types of errors encountered and the steps taken to address them, facilitating ongoing improvement.

  • Feedback Loop: Establish a feedback loop with users to acknowledge their reports and inform them of the actions taken. Transparency in the error-handling process builds trust with users.

  • Continuous Improvement: Use error reporting as a source of insights for model improvement. Analyze recurring issues and implement adjustments to the LLM's training and fine-tuning processes to reduce errors over time.

  • Ethical Guidelines: Develop and adhere to clear ethical guidelines for error reporting and content moderation. Ensure that reviewers are aware of these guidelines and receive appropriate training.

Improving prompt management

In a Language Model (LLM) platform, the efficacy of generating accurate and contextually appropriate responses is heavily reliant on the quality of prompts provided. Prompt management, encompassing the systematic organization, version control, and strategic deployment of prompts, holds a pivotal role in optimizing the functionality and user experience of LLMs.

As LLM platforms scale in both usage and complexity, the sheer volume of prompts required for diverse scenarios can become overwhelming. Without a streamlined prompt management strategy, developers can struggle to locate and utilize the most effective prompts for specific tasks.

Effective prompt management is also integral to achieving consistency in brand voice, style, and intended communication. Whether it's maintaining a formal tone, a specific writing style, or adhering to industry jargon, coherent prompt management ensures a harmonious output that aligns with an organization's objectives.

By improving prompt management, LLM platforms gain the capability to streamline workflows, save time, and enhance content accuracy. This optimization results in increased user satisfaction, improved response quality, and the potential to explore novel applications of LLMs.

Finally, the iterative nature of AI model training and the ongoing improvements in LLMs necessitate constant prompt adjustments, experimentation, operations, and monitoring.
