As artificial intelligence continues to advance at a rapid pace, researchers at companies like OpenAI are working at the forefront of developing increasingly capable AI models and systems. In this article, we'll explore insights from Karina, an AI researcher at OpenAI, on the latest developments in AI and what the future may hold.
The Art and Science of Model Training
One of the most fascinating aspects of AI development is the process of training large language models. As Karina explains, model training is "more an art than a science in a lot of ways." Some key considerations in model training include:
- Data quality is crucial - ensuring high quality data for the desired model behaviors and interactions
- Debugging models is similar to debugging software
- There's a delicate balance between making models helpful vs. potentially harmful
- Models can get confused by conflicting information in training data
For example, Karina shared that when training early versions of Claude at Anthropic, they discovered issues when teaching the model about its own capabilities:
"When you taught the model some of the self-knowledge of 'hey, you actually don't have a physical body to operate in the physical world' but then at the same time we had data that kind of taught the model some function calls which is like 'this is how you set an alarm' - the model would get extremely confused about whether it can set an alarm if it doesn't have a body in the physical world."
This highlights the nuanced challenges involved in training AI systems to have accurate self-knowledge and capabilities.
The Power of Synthetic Data
A common concern in AI development is the potential for models to hit a "data wall" - running out of high quality training data from the internet and other sources. However, Karina believes synthetic data will allow models to continue improving:
"People say we're hitting the data wall...I think people think more in terms of pre-trained large models that are trained on the entire internet to predict the next token. But what the model is actually learning during that process is how to compress - it's a compression algorithm. The model learns to compress a lot of knowledge and it learns how to model the world."
She explains that in the "post-training world," there are essentially infinite tasks that models can be taught through reinforcement learning:
"We went from raw datasets from pre-trained models to an infinite amount of tasks that you can teach the model in the post-training world via reinforcement learning. Any task - for example, how to search the web, how to use the computer, how to write well - all sorts of tasks."
This ability to generate synthetic training data and tasks allows models to continue improving beyond just ingesting existing internet data.
Developing New AI Capabilities
Karina provided fascinating insights into how researchers at OpenAI approach developing new AI capabilities and features. For example, when creating the new Canvas feature for ChatGPT, they focused on teaching the model three core behaviors:
- When to trigger Canvas for certain types of prompts vs. when not to
- How to update documents based on user requests (e.g. editing specific sections)
- How to make relevant comments on documents
To train these behaviors, they used a combination of synthetic data generation and iterative testing and refinement. As Karina explains:
"The way you synthetically train the model is basically figuring out what are the most core behaviors that you want this product feature to do...You teach both how to trigger the edit itself but also how do you teach the model to get higher quality edits."
This process of rapidly iterating on model behaviors and capabilities is key to developing new AI features and products.
The Importance of Evaluations
A critical part of AI development is creating robust evaluations to measure progress and ensure models are behaving as intended. Karina emphasized how important it is for product teams to learn how to create effective evals:
"I think my time...when I first came I was mostly like research IC work, so I was building a lot of...changing models, writing code, writing evals, working with PMs and designers to teach them how to even think about evaluations."
She explained that evals can take different forms:
- Deterministic evals with clear pass/fail criteria
- Human evaluations comparing different model versions
- Measuring win rates of new models vs. previous versions
Creating good evals is crucial for tracking progress and ensuring models are improving in the desired ways.
The Changing Nature of Product Development
As AI capabilities advance, the process of product development is evolving. Karina noted that prompting and working directly with AI models is becoming an important prototyping tool:
"Prompting is a new way of product development or prototyping for designers and product managers."
She gave examples of using AI prompting to prototype features like personalized start prompts and auto-generated conversation titles. This allows teams to rapidly test ideas before investing in full development.
Karina also highlighted how AI is enabling new types of product experiences, like the ability to upload and analyze entire books or documents. Features that seemed impossible a few years ago are now becoming commonplace.
Key Skills for the AI Era
As AI systems become more capable, there's understandable concern about which skills will remain valuable for humans. Karina offered some insights on skills she believes will be important going forward:
- Creative thinking and idea generation
- Listening to users and rapidly iterating
- Connecting dots across different fields
- Prioritization and resource allocation
- Communication and collaboration
- Management and people skills
- Empathy and understanding people
She noted that "soft skills" like creativity, management, and emotional intelligence are areas where AI still struggles:
"I think it's actually really really hard to teach the model how to be aesthetic or do really good visual design or how to be extremely creative in the way they write."
Focusing on these uniquely human capabilities may be valuable as AI advances.
The Future of AI Interfaces
Looking ahead, Karina is excited about new ways for humans to interact with AI systems. Some possibilities she mentioned:
- AI agents that can operate computer interfaces to complete tasks
- Collaborative AI assistants that learn user preferences over time
- Simulated versions of experts or public figures to interact with
- Seamless transformation between different content types (text, audio, video, etc.)
She believes we're still in early days of figuring out the best interfaces and experiences for interacting with increasingly capable AI.
Differences Between AI Companies
Having worked at both Anthropic and OpenAI, Karina offered some interesting comparisons between the companies:
- Anthropic has a strong focus on model behavior, personality, and ethics
- OpenAI allows more creative freedom and risk-taking in research
- Anthropic (when smaller) was very focused on prioritization
- OpenAI's larger scale enables more exploratory research
She noted that overall the companies are "more similar than different" in many ways.
Exciting Milestones in AI Progress
Reflecting on her time in the field, Karina highlighted some exciting milestones that expanded the possibilities of AI:
- 100k context windows allowing analysis of entire books/documents
- Voice interfaces enabling natural conversations with AI
- Computer-using AI agents that can complete tasks autonomously
She's particularly excited about the potential for AI to enable new forms of content creation and transformation between mediums.
Conclusion
As AI capabilities continue to advance rapidly, researchers like Karina are working at the cutting edge to develop new possibilities. From synthetic data generation to novel interface paradigms, the field of AI is brimming with potential.
While there are certainly challenges ahead, the future looks bright for continued AI progress. By focusing on uniquely human skills like creativity and emotional intelligence, we can work alongside increasingly capable AI systems to unlock new realms of possibility.
The coming years promise to be an exciting time of discovery and innovation in artificial intelligence. Researchers, product teams, and users alike will all play a role in shaping the future of this transformative technology.
