With a one-click integration to Conversations, Infobip’s contact center solution, HumanFirst helps enterprise teams leverage LLMs to analyze 100% of their customer data.
Personal and professional history might not repeat, but it certainly rhymes. I’m thrilled to join the team at HumanFirst, and reconnect with a team of founders I not only trust, but deeply admire.
With a one-click integration to Conversations, Infobip’s contact center solution, HumanFirst helps enterprise teams leverage LLMs to analyze 100% of their customer data.
Due to the highly unstructured nature of Large Language Models (LLMs), there are thought and market shifts taking place on how to implement LLMs.
Why do I say LLMs are unstructured? LLMs are to a large extent an extension of Conversational AI.
Due to the unstructured nature of human language, the input to LLMs are conversational and unstructured, in the form of Prompt Engineering.
And the output of LLMs is also conversational and unstructured; a highly succinct form of natural language generation (NLG).
LLMs introduced functionality to fine-tune and create custom models. And an initial approach to customising LLMs was creating custom models via fine-tuning.
This approach has fallen into disfavour for three reasons:
As LLMs have both a generative and predictive side. The generative power of LLMs is easier to leverage than the predictive power. If the generative side of LLMs are presented with contextual, concise and relevant data at inference-time, hallucination is negated.
Fine-tuning LLMs involves training data curation, transformation and cost. Fine-tuned models are frozen with a definite time-stamp and will still demand innovation around prompt creation and data presentation to the LLM.
When classifying text based on pre-defined classes or intents, NLUstill has an advantage with built-in efficiencies.
The aim of fine-tuning of LLMs is to engender more accurate and succinct reasoning and answers. This also solves for one of the big problems with LLMs; hallucination, where the LLM returns highly plausible but incorrect answers.
As seen below, there has been an emergence of vector stores / databases with semantic search, to provide the LLM with a contextual and relevant data snippet to reference.
Vector Stores, Prompt Pipelines and/or Embeddings are used to constitute a few-shot prompt. The prompt is few-shot because context and examples are included in the prompt.
The process of creating contextually relevant prompts are further aided by Autonomous Agents, prompt pipelines where a prompt is engineered in real-time based on relevant available data, conversation context and more.
Prompt chaining is a more manual and sequential process of creating a flow within a visual designer UI which is fixed and sequential and lacks the autonomy of Agents. There are advantages and disadvantages to both approaches; and both can be used in concert.
Lastly, an emerging field is testing different LLMs against a prompt; as opposed to in the past where we would focus on only testing various prompts against one single LLM. These tools include LangSmith, ChainForge and others.
The importance of determining the best suited model for a specific prompt addresses the notion that within enterprise implementations, multiple LLMs will be used.
I’m currently the Chief Evangelist @ HumanFirst. I explore & write about all things at the intersection of AI & language; ranging from LLMs, Chatbots, Voicebots, Development Frameworks, Data-Centric latent spaces & more.
