The air at DevSparks 2026 in Bengaluru was thick with the buzz of possibility, but also a quiet undercurrent of introspection. For many in India’s bustling tech scene, especially those leading in-house AI initiatives, the past couple of years have presented a profound existential question. It’s a question that Ramprakash Ramamoorthy, Director of AI Research at Zoho Corp, addressed head-on, tracing a fascinating pivot that redefined the very purpose of Zoho Labs. His insights resonated deeply, offering a blueprint for adaptability in an AI landscape reshaped by open-weight models.

For years, the gold standard for any serious tech company with AI ambitions was to build its own models from the ground up. Proprietary data, custom architectures, and the deep satisfaction of having crafted intelligence from scratch defined the cutting edge. Then, almost overnight, open-weight models arrived. These powerful AI models, with their parameters freely available for anyone to download, run, and even fine-tune, democratized access to advanced AI capabilities. They dramatically lowered the barrier to entry, simultaneously solving a problem for many while creating a brand new one for established in-house AI teams: If the fundamental models are now free and accessible, what exactly is our unique value proposition?

The Genesis of a Problem, and a Solution

To truly understand Zoho Labs’ pivot, one must first appreciate its original mandate. Zoho, a company renowned for its sprawling portfolio of over 100 products, faced a classic scaling challenge. Across its diverse product lines, from CRM to finance, IT management to collaboration tools, engineering problems related to AI and data kept recurring. Different teams, working independently, would often find themselves wrestling with the same core issues: how to efficiently extract insights from unstructured text, how to build robust recommendation engines, or how to implement smart automation. This led to duplicated effort, wasted resources, and a slower pace of innovation across the board.

Zoho Labs was established precisely to tackle this. Its mission was to serve as a central intelligence unit, a nexus where these common engineering hurdles could be identified early, solved once with expertise, and then disseminated as reusable solutions across the entire Zoho ecosystem. It was a strategic move to optimize engineering efforts and accelerate the integration of cutting-edge AI capabilities into every product. The lab was designed to be a force multiplier, preventing teams from repeatedly hitting the same dead ends. This foundational problem-solving DNA, focused on practical application and efficiency, proved crucial when the seismic shift of open-weight models began to reverberate.

When Open-Weight Models Changed Everything

The advent of open-weight models, while a boon for many, presented a complex challenge for teams like Zoho Labs that had invested heavily in building bespoke models. The economic calculus of AI development shifted dramatically. Why spend months or even years and significant capital building a foundational model when a powerful, often equally capable, alternative could be downloaded and run for free? This wasn’t just a cost consideration; it was a question of strategic relevance. If the core “intelligence” was commoditized, where did the specialized expertise of an in-house AI lab truly lie?

Ramprakash shared that this was a moment of deep introspection for Zoho Labs. They had to ask themselves: What is our enduring value now? Is it still about building general-purpose models, or does our role evolve? The answer, arrived at after careful deliberation and a keen understanding of Zoho’s product-centric philosophy, was inference engineering. This wasn’t a retreat, but a strategic reorientation that leaned into the very strengths of their original mandate: solving practical engineering problems at scale.

The Rise of Inference Engineering: From Model Building to Model Maximizing

Inference engineering, at its core, is about optimizing the deployment, fine-tuning, and operationalization of AI models in real-world applications. It’s the critical bridge between a model existing in a research lab and its seamless, efficient, and impactful integration into a product that serves millions of users. With open-weight models handling much of the heavy lifting of foundational intelligence, the new challenge became how to make these models perform optimally, reliably, and cost-effectively for specific business needs.

For Zoho Labs, this meant shifting focus to a myriad of crucial aspects:

  • Efficient Deployment: How do you run these large models without breaking the bank on compute resources? This involves model compression, quantization, and specialized hardware acceleration techniques.
  • Fine-tuning for Specificity: General-purpose models are powerful, but they often need to be adapted to Zoho’s unique datasets, customer language, and product contexts. Inference engineering focuses on efficient fine-tuning strategies that extract maximum relevance and accuracy with minimal data and computational overhead.
  • Latency and Throughput Optimization: In real-time applications, every millisecond counts. Ensuring that AI predictions are delivered swiftly and that the system can handle a high volume of requests is paramount.
  • Cost Management: Running AI models, especially large ones, can be expensive. Zoho Labs now concentrates on minimizing the operational costs associated with inference, exploring techniques like batching, caching, and serverless deployments.
  • Reliability and Robustness: Ensuring that models perform consistently and don’t produce unexpected or biased outputs in production environments. This includes monitoring, error handling, and continuous improvement loops.
  • Seamless Integration: Making sure that AI capabilities aren’t just an add-on, but are deeply embedded and enhance the user experience across Zoho’s vast product suite.

This pivot wasn’t merely a technical shift; it was a strategic declaration. It affirmed that the value of an in-house AI team isn’t solely in creating foundational models, but in expertly wielding and integrating them to create tangible business value. It’s about maximizing the return on investment from both proprietary efforts and readily available open-source intelligence.

Implications for India’s Deep Tech Ecosystem

Zoho Labs’ journey offers a compelling case study for India’s burgeoning deep tech ecosystem. For early-stage founders and budding entrepreneurs, especially those leveraging AI, this paradigm shift has significant implications. It suggests that while building novel foundational models remains a domain for well-funded research labs and global giants, the true competitive edge for many startups will lie in their ability to master inference engineering. It’s about taking powerful, accessible AI and crafting it into highly specific, efficient, and indispensable solutions for India’s unique pain points.

Consider a healthtech startup aiming to analyze medical images. Instead of building a new vision model from scratch, they can leverage an open-weight model and focus their efforts on fine-tuning it with Indian demographic data, optimizing its deployment for low-resource clinics, and integrating it seamlessly into a diagnostic workflow that truly helps doctors in tier-2 cities. Similarly, in agritech, optimizing crop disease detection models for local soil conditions and delivering real-time insights to farmers via efficient mobile applications becomes the key differentiator.

This focus on inference engineering also aligns well with the ethos of many Indian incubators and accelerators. Programs at T-Hub, CIIE, and even the IIT and IIM ecosystem often emphasize problem-solving and market fit over pure research. Founders are encouraged to build solutions for real-world problems, and mastering the deployment and optimization of AI models directly serves this goal. Government initiatives like Startup India, which aim to foster innovation, will likely see a surge in startups that are adept at this practical application of AI, rather than just its theoretical development.

The human story here is one of adaptability and strategic foresight. Ramprakash Ramamoorthy’s articulation wasn’t just about a technical shift; it was about a philosophical evolution. It acknowledged that the landscape had changed and that true innovation now lay not just in creation, but in intelligent application and optimization.

Looking Ahead: The Craft of Applied Intelligence

The pivot by Zoho Labs to inference engineering is more than just a company-specific strategy; it’s a bellwether for the broader AI industry. It signals a maturation of the field, moving beyond the initial race to build the biggest, most powerful models, towards a refined focus on practical, scalable, and cost-effective application. It underlines that the real magic often happens not in the lab where the model is born, but in the trenches where it is deployed, refined, and made to solve real-world problems.

For India, a nation poised to leverage AI across every sector, this shift is particularly pertinent. It opens up avenues for innovation that don’t require billions in R&D, but rather a deep understanding of local context, engineering prowess, and a relentless focus on efficiency. The future of AI, as Zoho Labs exemplifies, isn’t just about raw intelligence; it’s about the craft of applied intelligence, meticulously engineered to deliver impact.
