Gleen: Solving LLM Hallucinations

Gleen: Solving LLM Hallucinations

The News: On September 5, Gleen announced it has raised $4.9 million to accelerate its work in solving a major issue with large language models (LLMs)—hallucination. Gleen AI is focused on improving LLM-based chatbots that are focused on customer support/customer service, and it is now publicly available.

LLM-based chatbots tend to hallucinate, responding to queries with completely fabricated information. To address this problem, Gleen created a proprietary AI layer, independent of the LLM, that ingests enterprise knowledge across multiple sources, manages it, selectively feeds knowledge to the LLM, and cross-checks the quality of the LLM’s response, eliminating hallucination. Gleen AI is LLM-agnostic. It currently works with GPT 3.5 and 3.4, Anthropic, and Llama, and it is integrated into Slack, Discord, and other leading help desk solutions. Gleen provides software development kits (SDKs) and REST APIs for customers to integrate directly. Read the full blog post on the public availability of Gleen AI on the Gleen website.

Gleen: Solving LLM Hallucinations

Analyst Take: It is interesting that given the potential impact of LLMs there is so much work involved in making them behave properly. Hallucination is a big challenge. Is Gleen the type of solution to solve it? What about other LLM challenges? Here are some of the key takeaways from Gleen’s debut.

Gleen Is on To Something

Hallucination is a massive issue for LLMs, and if Gleen can solve this problem, it could translate into real productivity gains for generative AI applications. On paper, the Gleen AI solution is interesting and makes sense as a solution that might be able to mitigate LLM hallucination. The fact that Gleen AI is an abstraction layer, independent of the LLM, makes this solution compelling and enables it to be LLM-agnostic. It is unclear whether navigating that layer with data will mean additional costs for data processing.

Hallucinations Are Not the Only Accuracy-Focused LLM Challenge

Hallucination is only one of several challenges enterprises face in deploying LLMs. To be fair, Gleen is also addressing false confidence and some accuracy issues with Gleen AI. Other issues that Gleen AI might also be able to solve explanability issues; however, Gleen AI probably does not provide the sources to back up its conclusions of the corrected answers. Another issue it might not solve is mitigating bias—LLMs tend to require a heavy dose of pre-production monitoring to weed out bias language and answers.

Cost Issues for Running LLMs

A cottage industry has sprung up to address cost issues for leveraging LLMs. Current compute costs for LLMs can be expensive. As a result, there are massive efforts by a number of chip manufacturers to build more efficient, purpose-built AI chips; a range of development tools have been designed to help AI models for LLMs to run more efficiently; and there are LLMs that are trained on smaller data sets.

Conclusion

Hallucination is not the only challenge enterprises using LLMs face, but it is a significant one worth solving. If Gleen’s concept works, players will scramble to build similar solutions, particularly larger AI development platforms/tools vendors, including the LLM players themselves. Gleen’s focus is on hallucinations or customer service chatbots, but LLMs do not discern in their hallucinations, which means it is likely that savvy players will develop hallucination fighters for all LLM applications.

Welcome

The vision behind everything in Futurum’s Custom Research practice is this: research should show you what is happening, what comes next, and what to do about it. It should be personal to each audience, easy for people to grasp, and structured so LLMs can reason over it accurately. And it should be fast and turnkey; you want answers now, not another project to carry for quarters.

Whether you are defining business, channel, or go-to-market strategy; evaluating vendors or justifying ROI; or commissioning research to fill an emerging market need, we have your back, with a program that answers your questions with the objectivity and credibility to drive real decisions.

To do it, we bring unmatched data to bear: Futurum research, surveys, and market projections; validated market feeds; ETR’s 15 years of insight from 10,000 technology decision-makers; G2’s buyer and user data; and what our analysts hear every day. Add leading primary collection, from AI-moderated voice interviews to surveys and analyst-led interviews, all turnkey, and every project comes out credible, nuanced, and actionable.

And we don’t just drop the results in your lap. For internal work, we provide analyst-led sessions, interactive dashboards, and a range of formats. For market-facing work, Futurum delivers turnkey activation and amplification that actually gets seen, by people and by LLMs, through our media and share of voice. This is research that moves decisions and markets.

We will meet you wherever you are, from a fast-turn brief to a multi-year program, and shape the work to your goals, timeline, and budget. The right program for your moment.

If any of this is useful, I would love to talk.
