LLMs are Getting Better and Smaller Let’s look at Llama as an example. The rapid evolution of these models highlights a key trend in AI: prioritizing efficiency and performance. When Llama 2 70B launched in August 2023, it was considered a top-tier foundational model. However, its massive size demanded powerful hardware like the NVIDIA H100 accelerator. Less than nine months later, Meta introduced Llama 3 8B, shrinking the model by almost 9x. This enabled it to run on smaller

Building a great product is only half the battle. Demonstrating its capabilities convincingly — whether in front of customers, at an exhibition, or during a PoC — is often what seals the deal. Yet, for many companies, setting up demos ends up as a side project that falls through the cracks. At Whileone , we understand this challenge. That’s why helping companies build reliable, repeatable demos has been part of our mission since day one. The Problem with Ad-Hoc Demos Most com

Meta’s Llama 4 Scout, released in April 2025, is a 17-billion parameter general-purpose language model that brings powerful reasoning to a broader range of applications—including those running without GPUs.

JetStream is a JavaScript benchmark suite that evaluates web application performance by measuring the execution latency and throughput of complex workloads. With the release of JetStream 2.2, we at WhileOne Techsoft undertook the task of migrating its harness to a modern Node.js-based setup . Recently while working with a customer who was looking to benchmark their CPU using some js workloads. This post dives into why we did it, how we did it, and what you can expect from th

SPEC CPU2017 is a well-known benchmark suite for evaluating CPU-intensive performance. Although it assumes native compilation and execution, there are cases—especially with RISC-V (RV64) platforms—where cross-compilation is the only feasible route. This guide walks through the steps to cross-compile SPEC CPU2017 for RISC-V, transfer the binaries to a target system, and optionally use the --fake option to simulate runs where execution isn't possible or needed during develop

In May 2022, one of our customers asked us to tune Elasticsearch with Esrally for cloud providers. We started with trying multiple combinations of manual runs on all cloud providers. We were collecting scaling runs with 2/4/8/16 cores. In the above data collection, we could not see the proportionate scores. Hence, we decided to experiment with running the Elasticsearch ESRally benchmark throughout the day. As Esrally doesn’t run for a particular duration, we carried out the r
