Language models have undergone different phases of development. Initially, models relied on text prediction, where they attempted to complete text based on preceding context. This was known as the pre-trained era. Then came the phase of instruction tuning, where models were fine-tuned on examples to follow instructions. This improved their ability to perform specific tasks. The current phase is RLHF (Reinforcement Learning from Human Feedback), where models generate their own answers and receive human feedback to optimize their performance. This phase allows for more automated task completion and has improved models' capability to provide correct answers.
Large language models, like GPT-3, are sophisticated text prediction systems that generate text based on preceding context. They are trained on a variety of text sources and use techniques like instruction tuning and reinforcement learning to optimize their performance. These models are capable of answering questions and completing tasks by providing relevant information. While their responses may not be perfect, they have shown impressive language understanding and can generate coherent and plausible text. However, it's important to note that their performance is a result of training on extensive data and not a reflection of true understanding or consciousness.
There have been challenges in the development of large language models, such as mode collapse, where models tend to favor certain responses over others. Early models like GPT-3 had limitations in answering questions with misleading premises. However, advancements in instruction tuning and RLHF have improved their performance and addressed some of these issues. Models like TextDaVinci and ChatGPT have demonstrated the ability to provide correct answers and handle various types of queries effectively. Ongoing research and fine-tuning continue to enhance the capabilities of large language models.
Large language models have the potential to be powerful tools for natural language understanding and generation. They can be used in various applications, such as generating code, providing translations, summarizing text, and engaging in conversation. While their responses may not always be flawless, these models offer valuable assistance and insights. The development of RLHF and instruction tuning has enabled more reliable and accurate performance. As research progresses, further improvements can be expected, making large language models even more valuable in transforming various industries and applications.
It is emphasized that finding the best answer instead of a fair distribution is crucial, even though misgeneralizations may occur and constrain creativity.
Using pre-trained models in creative writing may lead to restricted and repetitive phrasing, but there are possibilities to balance this with pre-trained models from different years.
Language models are compared to Lego bricks, each with specific capabilities, that can be composed together to create innovative applications and improve search results.
Language models are identified as powerful tools for solving complex tasks that previously required ML expertise. They can understand specific problems and generate accurate solutions with clear instructions.
For anyone who discovered this show on Twitter, Riley (@goodside) likely needs no introduction – after all, he spent most of 2022 posting his explorations of OpenAI's text-davinci-002, and quickly became one of the must-follow accounts in AI. Riley Goodside is the world's first Staff Prompt Engineer at Scale AI, and is an expert in prompting large language models and integrating them into AI-powered applications. Few have spent as much time on the language model frontier, so I hope you enjoy this unique conversation with Riley Goodside.
We're hiring across the board at Turpentine and for Erik's personal team on other projects he's incubating. He's hiring a Chief of Staff, EA, Head of Special Projects, Investment Associate, and more. For a list of JDs, check out: eriktorenberg.com.
RECOMMENDED PODCAST:
The HR industry is at a crossroads. What will it take to construct the next generation of incredible businesses – and where can people leaders have the most business impact? Hosts Nolan Church and Kelli Dragovich have been through it all, the highs and the lows – IPOs, layoffs, executive turnover, board meetings, culture changes, and more. With a lineup of industry vets and experts, Nolan and Kelli break down the nitty-gritty details, trade offs, and dynamics of constructing high performing companies. Through unfiltered conversations that can only happen between seasoned practitioners, Kelli and Nolan dive deep into the kind of leadership-level strategy that often happens behind closed doors. Check out the first episode with the architect of Netflix’s culture deck Patty McCord.
