Regardless of the hype round generative AI, research present only a fraction of GenAI initiatives have made it into manufacturing. An enormous purpose for this shortfall is the priority organizations have in regards to the tendency for giant language fashions (LLMs) to hallucinate and provides inconsistent solutions. A method organizations are responding to those issues is by implementing belief layers for AI.
Generative fashions, corresponding to LLMs, are highly effective as a result of they are often educated utilizing giant quantities of unstructured information, after which reply to questions based mostly on what they’ve “realized” from stated unstructured information (textual content, paperwork, recordings, photos, and movies). Organizations are discovering this generative functionality extremely helpful for the creation of chatbots, co-pilots, and even semi-autonomous brokers that may deal with language-based duties on their very own.
Nevertheless, an LLM person has little management over how the pre-trained mannequin will reply to those questions, or prompts. And in some circumstances, the LLM will generate wild solutions utterly disconnected from actuality. This tendency to hallucinate–or as NIST calls it, to confabulate—can’t be absolutely eradicated, as its inherent with how these kind of non-deterministic, generative fashions are designed. Subsequently, it should be monitored and managed.
One of many methods organizations can hold LLMs from going off the rails is by implementing an AI belief layer. An AI belief layer can take a number of varieties. Salesforce, for instance, makes use of a number of approaches to scale back the chances {that a} buyer has a poor expertise with its Einstein AI fashions, together with through the use of safe information retrieval, dynamic grounding, and information masking, toxicity detection, and nil retention through the prompting stage.

Whereas the Salesforce Einstein Belief Layer is gaining floor amongst Salesforce clients, different organizations are in search of AI belief layers that work with a variety of various GenAI platforms and LLM fashions. One of many distributors constructing an impartial AI belief layer that may work throughout a variety of platforms, techniques, and fashions is Galileo.
Voyage of AI Discovery
Earlier than co-founding Galileo in 2021 with fellow engineers Atindriyo Sanyal and Vikram Chatterji, COO Yash Sheth spent a decade at Google, the place he constructed LLMs for speech recognition. The early publicity to LLMs and expertise working with them taught Sheth lots about how these kind of fashions work–or don’t work, because the case could also be.
“We noticed that LLMs are going to unlock 80% of the world’s data, which is unstructured information,” Sheth informed BigDATAwire in an interview at re:Invent final month. “Nevertheless it was extraordinarily onerous to adapt or to use these fashions onto completely different purposes as a result of these are non-deterministic techniques. Not like every other AI that’s predictive, that provides you an identical reply each time, generative AI doesn’t provide the similar reply each time.”
Sheth and his Galileo co-founders acknowledged very early on that the non-deterministic nature of those fashions would make it very tough to get them into manufacturing in enterprise accounts, which have much less urge for food for threat in the case of privateness, safety, and placing one’s repute on the road than the move-fast-and-break-stuff Silicon Valley crowd. If these LLMs had been going to be uncovered to tens of thousands and thousands of individuals and obtain the trillions of {dollars} in worth which were promised, this downside needed to be solved.
“To truly mitigate the danger when it’s utilized to mission important duties,” Sheth stated, “you have to have a belief framework round it that may make sure that these fashions behave the way in which we would like them to be, on the market within the wild, in manufacturing.”
Beginning in 2021, Galileo has taken a essentially completely different strategy to fixing this downside in comparison with most of the different distributors which have popped up since ChatGPT landed on us in late 2022, Sheth stated. Whereas some distributors had been fast to use frameworks for conventional machine studying, Galileo spent the higher a part of two years conducting analysis, publishing papers, and growing its first product constructed particularly for language fashions, Generative AI Studio, which it launched in August 2023.
“We wish to be very thorough in our analysis as a result of once more, we aren’t constructing the device–we’re constructing the expertise that works for everybody,” Sheth stated.
Mitigating Unhealthy Outcomes
On the core of the Galileo’s strategy to constructing an AI belief layer is one other basis mannequin, which the corporate makes use of to investigate the conduct of the LLM at situation. On high of that, the corporate has developed its personal set of metrics for monitoring the LLM conduct. When the metrics point out unhealthy conduct is happening, they activate guardrails to dam it.
“The way in which this works is we now have our personal analysis basis fashions that act, and these are reliable, dependable fashions that provide the similar output each time,” Sheth defined. “And these are fashions that may run on a regular basis in manufacturing at scale. Due to the non-deterministic nature, you wish to arrange these guardrails. These metrics which might be computed every time in manufacturing and in actual time, in low latency, block the hallucinations, block unhealthy outcomes from occurring.”

There are three elements of Galileo’s suite right this moment: Consider, for conducting experiments throughout a buyer’s GenAI stack; Observe which displays LLM conduct to make sure a safe, performant, and constructive person expertise;, and Shield, which prevents LLMs from responding to dangerous requests, leaking information, or sharing hallucinations.
Taken collectively, the Galileo suite permits clients to belief their GenAI purposes the identical means they belief their common apps developed utilizing deterministic strategies, Sheth stated. Plus, they will run Galileo wherever they like: on any platform, AI mannequin, or system.
“Right this moment software program groups can ship or launch their purposes nearly every day. And why is that attainable?” he asks. “Twenty years in the past, across the dot-com period, it used to take groups 1 / 4 to launch the subsequent model of their utility. Now you get an replace in your cellphone each like each few days. That’s as a result of software program now has a belief layer.”
The tooling concerned in an AI belief layer look considerably completely different than what a regular DevOps workforce is used to, that’s as a result of the expertise is essentially completely different. However the finish end result is identical, in line with Sheth–it offers growth groups the peace of thoughts to know that, if one thing goes awry in manufacturing, will probably be rapidly detected and the system could be rolled again to a identified good state.
Gaining GenAI Traction
Since launching its first product barely a year-and-a-half in the past, Galileo has begun to generate some momentum. The corporate has a handful of shoppers within the Fortune 100, together with Comcast, Twilio, and ServiceNow, and established a partnership with HPE in July. It raised $45 million in a Sequence B spherical in October, bringing its complete enterprise funding to $68.1 million.
As 2025 kicks off, the necessity for AI belief layers is palpable. Enterprises are champing on the bit to launch their GenAI experiments into manufacturing, however officers simply can’t log off till a number of the tough edges are sanded down. Sheth is satisfied that Galileo has the appropriate strategy to mitigating unhealthy outcomes from non-deterministic AI techniques, and giving enterprises the arrogance they should inexperienced gentle the GenAI.
“There are wonderful use circumstances that I’ve by no means seen attainable with conventional AI,” he stated. “When mission important software program begins changing into infused by AI, what’s going to occur to the belief layer? You’re going to return to the stone ages of software program. That’s what’s hindering all of the POCs which might be occurring right this moment from reaching manufacturing.”
