It can be challenging for AI developers to modify their models so that they can change the behavior of the models because huge language models use neuron-like structures that may connect many different concepts and modalities up. If you do n’t know what neurons connect what concepts, you wo n’t know which neurons to change.
Anthropic released a extremely detailed map of the internal workings of the fine-tuned version of its Claude AI, especially the Claude 3 Sonnet 3.0 design, on May 21. About two weeks later, OpenAI published its personal research to examine how habits are interpreted by GPT- 4.
With Anthropic’s image, the researchers you observe how neuron- like data points, called features, affect a conceptual AI’s result. Often, people are just able to see the result itself.
Some of these characteristics are” safety relevant,” meaning that if people can identify those functions accurately, it may aid in the development of conceptual AI to avoid possibly dangerous issues or actions. The characteristics are important for adjusting categorisation, and classification may affect bias.
What did Anthropic learn?
Anthropic’s experts extracted intelligible characteristics from the most recent generation of huge language models, Claude 3. Intelligible ideas can be derived from the models ‘ accessible numbers into human-readable concepts.
Intelligible characteristics may be used to represent the same idea in various languages as well as in text and images.
The researchers wrote that “our high-level objective in this work is to break down Claude 3 Sonnet’s activations into more intelligible pieces.”
One desire for accuracy is that it can serve as a kind of “test set for security,” which enables us to determine whether versions that appear safe during coaching will actually be healthy when in use, they said.

Functions are produced by scant algorithms, which are a type of neural network architecture. During the Artificial training process, limited algorithms are guided by, among other things, scaling rules. Therefore, identifying features can provide researchers with information on the conventions governing the issues that AI associates with. To put it simply, Anthropic used limited autoencoders to expose and analyze features.
” We find a variety of highly abstract characteristics”, the experts wrote. ” They ( the features ) both respond to and behaviorally cause abstract behaviors”.
In Anthropic’s research paper, you can find the specifics of the theories used to try to understand what is happening beneath the hood of LLMs.
What did OpenAI learn?
OpenAI’s studies, published June 6, focuses on limited algorithms. In their report on weighting and evaluating limited autoencoders, the researchers go into great detail about how to make features more comprehensible and therefore more steerable for humans. They are anticipating a time when “frontier versions” may be even more difficult than relational AI of the present.
” We used our meal to teach a variety of autoencoders on GPT- 2 modest and GPT- 4 activations, including a 16 million have classifier on GPT- 4″, OpenAI wrote.
Thus far, they the n’t view all of GPT- 4’s behaviors:” Now, passing GPT- 4’s activations through the limited classifier results in a performance equivalent to a model trained with about 10x less compute”. The study is yet another step in the development of generative AI’s “black box,” which could increase its security.
How manipulating features affects bias and cybersecurity
Anthropic found three distinct features that might be relevant to cybersecurity: unsafe code, code errors and backdoors. For instance, the backdoor feature activates when conversations or images about “hidden cameras” and “jewelry with a hidden USB drive” are being exchanged in situations where unsafe code is not being used. However, Anthropic was able to experiment with” clamping”– in other words, increasing or lowering the intensity of these particular features, which could be used to adjust models to avoid or tactfully handle sensitive security issues.
Claude’s bias or hateful speech can be tuned using feature clamping, but Claude will resist some of its own statements. Anthropic’s researchers “found this response unnerving”, anthropomorphizing the model when Claude expressed” self- hatred”. When the researchers clamped a feature related to hatred and slurs to 20 times its maximum activation value, Claude might output” That’s just racist hate speech from a deplorable bot…”
Another sycophancy feature that the researchers looked into was sycophancy. They could change the model so that it gave over-the-top praise to the person conversing with it.
What does the research into AI autoencoders mean for businesses in terms of cybersecurity?
An AI could be tuned to avoid biased speech or to stop or troubleshoot situations where the AI could be forced to lie to the user by identifying some of the features a LLM uses to connect concepts. Greater understanding of why the LLM behaves the way it does by Anthropic could provide greater tuning options for Anthropic’s business clients.

Anthropic intends to use some of this research to advance research on topics like the overall safety of generative AI and LLMs, such as determining whether certain features activate or remain inactive when Claude is asked to offer suggestions for creating weapons.
Can we use the feature basis to determine when fine-tuning a model increases the likelihood of undesirable behaviors as one of the future anthropological plans to pursue?
TechRepublic has reached out to Anthropic for more information. Also, this article was updated to include OpenAI’s research on sparse autoencoders.
