Why Writer’s Palmyra LLM is the little AI model that could for enterprises

Writer, a three-year-old San Francisco-based startup which raised $100 million in September 2023 to deliver its proprietary, enterprise-focused massive language fashions to extra firms, doesn’t hit the headlines as typically as OpenAI, Anthropic or Meta — and even as a lot as sizzling LLM startups like France-based Mistral AI.

However Author’s household of in-house LLMs, known as Palmyra, might be the little AI fashions that might, not less than on the subject of enterprise use circumstances. Firms together with Accenture, Vanguard, Hubspot and Pinterest are Author shoppers, utilizing the corporate’s creativity and productiveness platform powered by Palmyra fashions.

Stanford HAI‘s Heart for Analysis on Basis Fashions added new fashions to their benchmarking final month and developed a brand new benchmark, known as HELM Lite, that comes with in-context studying. For LLMs, in-context studying means studying a brand new activity from a small set of examples offered inside the immediate on the time of inference.

Author’s LLMs carried out ‘unexpectedly’ nicely on AI benchmark

Whereas GPT-4 topped the leaderboard on the brand new benchmark, Palmyra’s X V2 and X V3 fashions “maybe unexpectedly” carried out nicely “regardless of being smaller fashions,” posted Percy Liang, director of the Stanford Heart for Analysis on Basis Fashions.

Palmyra additionally carried out notably nicely — touchdown in first place — within the space of machine translation. Author CEO Might Habib stated in a LinkedIn put up: “Palmyra X from Writer is doing EVEN BETTER than the basic benchmark. We aren’t simply the highest mannequin within the MMLU benchmark, however the prime mannequin in manufacturing general — shut second solely to the GPT-4 previews that have been analyzed. And throughout translation benchmarks — a NEW take a look at — we’re #1.”

Enterprises must construct utilizing economically viable fashions

In an interview with VentureBeat, Habib stated that enterprises could be hard-pressed to run a mannequin like GPT-4, educated on 1.2 trillion tokens, in their very own environments for an economically viable price. “Generative AI use circumstances [in 2024] at the moment are truly going to must make financial sense,” she stated.

She additionally maintained that enterprises are constructing use circumstances on a GPT mannequin after which “two or three months later the prompts don’t actually work anymore as a result of the mannequin has been distilled, as a result of their very own serving prices are so excessive.” She pointed to Stanford HAI’s HELM Lite benchmark leaderboard and maintained that GPT-4 (0613) is rate-limited, so “it will be distilled,” whereas GPT-Turbo is “only a preview, we do not know what their plans are for this mannequin.”

Habib added that she believes Stanford HAI’s benchmarking efforts are “closest to actual enterprise use circumstances and actual enterprise practitioners,” moderately than leaderboards from platforms like Hugging Face. “Their situations are a lot nearer to precise utilization,” she stated.

Habib co-founded Author, which started as a device for advertising groups, with Waseem AlShikh in mid-2020. Beforehand, the duo had run one other firm targeted on NLP and machine translation known as Qordoba, based in 2015. In February 2023, Author launched Palmyra-Small with 128 million parameters, Palmyra-Base with 5 billion parameters, and Palmyra-Giant with 20 billion parameters. With a watch on an enterprise play, Author introduced Information Graph in Might 2023, which permits firms to attach enterprise information sources to Palmyra and permits prospects to self-host fashions based mostly on Palmyra.

“After we say full stack, we imply that it’s the mannequin plus a built-in RAG resolution,” stated Habib. “AI guardrails on the appliance layer and the built-in RAG resolution is so essential as a result of what people are actually sick and uninterested in is needing to ship all their information to an embeddings mannequin, after which that information comes again, then it goes to a vector database.” She pointed to Author’s new launch of a graph-based strategy to RAG to construct digital assistants grounded in a buyer’s information.

For LLMs, dimension issues

Habib stated she has at all times had a contrarian view that enterprises want smaller fashions with a robust deal with curated coaching information and up to date datasets. VentureBeat requested Habib a couple of latest LinkedIn from Wharton professor Ethan Mollick that cited a paper about BloombergGPT and said “the neatest generalist frontier fashions beat specialised fashions in specialised matters. Your particular proprietary information could also be much less helpful than you suppose on the planet of LLMs.”

In response, she identified that the HELM Lite leaderboard had medical LLM fashions beating out GPT-4. In any case, “as soon as you’re past the state-of-the-art threshold, issues like inference and price matter to enterprises too,” she stated. “A specialised mannequin can be simpler to handle and cheaper to run.”
