A new startup named Lutra AIlaunched today with a platform aimed at helping users create personal artificial intelligence workflows and automate repetitive tasks without the need for deep technical expertise.

Lutra is led by co-founder and Chief Executive Jiquan Ngiam, who previously worked at Google LLC and the online education provider Coursera Inc. He saw an opening to use AI to provide nontechnical users a path to build automation projects for tasks that can connect workflows.

The companys goal is to integrate AI with already existing tools such as Slack, Microsoft Outlook and Google Workspace to allow users to describe what they do day-to-day and have an AI assistant prepare a workflow for them. This could be something such as managing incoming emails, performing financial research or summarizing and extracting data from PDF documents for a reporting system thats done daily.

Ngiam said his time working at Coursera and Google gave him the insight that users needed something to simplify the process of automating workflows. So he got together with friends, including the companys co-founder Vijay Vasudevan, who also worked at Google, to look at AI models that could become assistants for nontechnical users by allowing them to use conversational English to describe what they need.

It made me think about the ability of these models to generate code and reasoning, then figure out the environment about making it more useful for non-engineers, Ngiam toldTechCrunch. There was this question about can these models now code in a way that interconnects all the software we use to then do very useful things for us reliably and securely.

What Lutra developed is a code-first AI assistant that allows users to describe their workflow and goals in natural language to an AI assistant, which will then ask follow-up questions to refine the automation. This means that essentially, its like talking to a coworker or developer who is writing code to connect apps to automate tasks.

The idea behind the AI assistant is to deliver an automated workflow to users as if they are programming in English. By describing the workflow that they want, the AI assistant guides them through the process and gives them visibility end-to-end in the code that it produces. Lutra says that because the AI models produce working software code for production-ready environments that connects enterprise data and apps, it can be done in a secure, reliable way.

Lutra recently raised $3.8 million in a seed funding round led by Coatue Ventures, with participation from Hustle Fund, Maven Ventures and a group of angel investors. The platform is currently in private beta as the team focuses on expanding it to more customers, but there is a waitlist for users interested in early access.

Last week, a team of researchers from the University of California, Berkeley published a highly anticipated paper in the journal Nature describing an autonomous laboratory or A-Lab that aimed to use artificial intelligence (AI) and robotics to accelerate the discovery and synthesis of new materials.

Dubbed a self-driving lab, the A-Lab presented an ambitious vision of what an AI-powered system could achieve in scientific research when equipped with the latest techniques in computational modeling, machine learning (ML), automation and natural language processing.

However, within days of publication, doubts began to emerge about some of the key claims and results presented in the paper.

Robert Palgrave is an inorganic chemistry and materials science professor at University College London. He has decades of experience in X-ray crystallography. Palgrave raised a series of technical concerns on X (formerly Twitter) about inconsistencies he noticed in the data and analysis provided as evidence for the A-Labs purported successes.

In particular, Palgrave argued that the phase identification of synthesized materials conducted by the A-Labs AI via powder X-ray diffraction (XRD) appeared to be seriously flawed in several cases and that some of the newly synthesized materials were already discovered.

Palgraves concerns, which he aired in an interview with VentureBeat and a pointed letter to Nature, revolve around the AIs interpretation ofXRD data a technique akin to taking a molecular fingerprint of a material to understand its structure.

Imagine XRD as a high-tech camera that can snap pictures of atoms in a material. When X-rays hit the atoms, they scatter, creating patterns that scientists can read, like using shadows on a wall to determine a source objects shape.

Similar to how children use hand shadows to copy the shapes of animals, scientists make models of materials and then see if those models produce similar X-ray patterns to the ones they measured.

Palgrave pointed out that the AIs models didnt match the actual patterns, suggesting the AI might have gotten a bit too creative with its interpretations.

Palgrave argued this represented such a fundamental failure to meet basic standards of evidence for identifying new materials that the papers central thesis that 41 novel synthetic inorganic solids had been produced could not be upheld.

In a letter to Nature, Palgrave detailed a slew of examples where the data simply did not support the conclusions drawn. In some cases, the calculated models provided to match XRD measurements differed so dramatically from the actual patterns that serious doubts exist over the central claim of this paper, that new materials were produced.

Although he remains a proponent of AI use in the sciences, Palgrave questions whether such an undertaking could realistically be performed fully autonomously with current technology. Some level of human verification is still needed, he contends.

Palgrave didnt mince words: The models that they make are in some cases completely different to the data, not even a little bit close, like utterly, completely different. His message? The AIs autonomous efforts might have missed the mark, and a human touch could have steered it right.

Responding to the wave of skepticism, Gerbrand Ceder, the head of the Ceder Group at Berkeley, stepped into the fray with a LinkedIn post.

Ceder acknowledged the gaps, saying, We appreciate his feedback on the data we shared and aim to address [Palgraves] specific concerns in this response. Ceder admitted that while A-Lab laid the groundwork, it still needed the discerning eye of human scientists.

Ceders update included new evidence that supported the AIs success in creating compounds with the right ingredients. However, he conceded, a human can perform a higher-quality [XRD] refinement on these samples, recognizing the AIs current limitations.

Ceder also reaffirmed that the papers objective was to demonstrate what an autonomous laboratory can achieve not claim perfection. And upon review, more comprehensive analysis methods were still needed.

The conversation spilled back over to social media, with Palgrave and Princeton Professor Leslie Schoop weighing in on the Ceder Groups response. Their back-and-forth highlighted a key takeaway: AI is a promising tool for material sciences future, but its not ready to go solo.

Palgrave and his team plan to do a re-analysis of the XRD results, intending to produce a much more thorough description of what compounds were actually synthesized.

For those in executive and corporate leadership roles, this experiment is a case study in the potential and limitations of AI in scientific research. It illustrates the importance of marrying AIs speed with the meticulous oversight of human experts.

The key lessons are clear: AI can revolutionize research by handling the heavy lifting, but it cant yet replicate the nuanced judgment of seasoned scientists. The experiment also underscores the value of peer review and transparency in research, as expert critiques from Palgrave and Schoop have highlighted areas for improvement.

Looking ahead, the future involves a synergistic blend of AI and human intelligence. Despite its flaws, the Ceder groups experiment has sparked an essential conversation about AIs role in advancing science. Its a reminder that while technology can push boundaries, its the wisdom of human experience that ensures were moving in the right direction. This experiment stands as both a testament to AIs potential in material science and a cautionary tale. Its a rallying cry for researchers and tech innovators to refine AI tools, ensuring theyre reliable partners in the quest for knowledge. The future of AI in science is indeed luminous, but it will shine its brightest when guided by the hands of those who have a deep understanding of the worlds complexities.
