In my experience, to successfully exceute NLP project, public cloud providers has wide array of APIs & cloud products . You need to choose the cloud providers API for the following resources 1. Organizations doesn’t have enough expertise to build NLP solutions from ground up 2. Organizations has lesser time to market and ready to pay API call per usage 3. Organization doesn’t want to own any in house solution due to fact that they may be in different domain such as health , public sector , etc or smaller smart up The popular cloud providers are Google cloud., Azure & AWS.
Within the constraints of finite resources, particularly R&D teams and budgets in comparison to Bigtech companies, a pragmatic approach to Natural Language Processing (NLP) projects is crucial. Therefore, I advocate for leveraging existing Bigtech investments to maximize our time to value and expedite project success. My NLP projects primarily rely on cloud solutions, with a specific focus on Google Cloud Platform (GCP), because of its clear NLP roadmap and the PaLM2 Large Language Model (LLM) Advantage. However, recognizing the limitations of single-source reliance, we adopt a nuanced approach. In the specific instance of Speech-to-Text, we use Python Pyannote library for speaker identification, that has a better result than Google′s one.

Garbage in is still garbage out. Using LLMs ain't a magic bullet. Check label quality and text quality. Decide on an appropriate ML formulation, make a hypothesis on how ML can add value, choose a good metric, decide a baseline and build an ML MVP to see if data size and quality with ML model can add value.
For those who prefer a more customizable and hands-on approach, open-source NLP frameworks provide the flexibility to tailor models to specific project requirements. TensorFlow and PyTorch, both popular deep learning frameworks, offer NLP modules and pre-trained models.

Langchain is an open-source framework designed for developing and customizing agents and tools to fit specific use cases. It enables the adaptation of popular model responses to your unique framework and solution, offering easy integration with both OpenAI and open-source llama models. However, there's a trade-off to consider: using Langchain with OpenAI models can significantly increase token consumption and API costs. Alternatively, while open-source models won't incur direct API costs, they will introduce model hosting expenses to achieve comparable throughput and performance in end-to-end pipelines.
Why you should consider starting with LLMs: In 2023/24, Large Language Models (LLMs) became my 1st go-to for any language-related task, especially where in-house data science resources are scarce. I worked with several companies on multiple NLP projects and all had one thing in common - they included LLMs or were fully LLM-powered. Leading models (GPT-4, Gemini, Claude 2.1, etc.) proved good enough for several use cases (entity recognition, annotation, classification, labeling, translation, ASR, summarization, QnA), have an easy API integration and require less expertise and effort in order to provide initial value quickly. Steps: use ChatGPT to get initial intuition, use APIs to scale it, evaluate, combine "classic NLP" where needed
In modern enterprise use cases, using LLMs makes more sense than basic NLP frameworks. LLMs frameworks to consider: - LangChain: Simplified framework for LLM integration. - LlamaIndex: Vector store for LLM-based search. - Haystack: End-to-end pipeline for document search with LLMs. - Helicone: Framework for querying GPT models. - LLMFlow: Simplifies prompt generation for LLMs with a template-based approach. - LLM-Ops: Comprehensive framework for managing the entire LLM application lifecycle, including deployment, monitoring, and scaling. - BMTrain: Efficient training for Big Models.
