The commercial availability of SPRQ-Nx brings the per genome list price to $345, and the possibility of sub-$300 HiFi genomes to Revio customers sequencing at scale1, while expanded methylation detection and advances to DeepConsensus, an AI powered consensus algorithm developed in collaboration with Google, further improve accuracy, run performance, and the biological information generated from each read. PacBio has continued expanding the use of AI across the HiFi sequencing workflow in ways that directly improve data quality, speed, and biological interpretation. The latest DeepConsensus updates include optimizations enabled by Google’s AlphaEvolve coding agent, delivering measurable gains in accuracy and processing speed. PacBio is also advancing deep learning models for epigenetic detection, including updated 5mC and 6mA models optimized for SPRQ-Nx chemistry and a new 5-hydroxymethyl-cytosine, or 5hmC, caller. These advances are designed to help researchers generate richer HiFi datasets from the same sequencing run, including methylation signals relevant to cancer, tissue sequencing, and large-scale genomic research. When paired with SPRQ-Nx chemistry, these improvements translate directly to lower costs and higher performance in production environments. SPRQ-Nx allows the SMRT Cell consumable to be used multiple times, reducing sequencing costs to less than $300 per human genome at scale. In beta testing across 20 sites in Europe, Asia, and the United States, spanning over 1,400 runs, SPRQ-Nx delivered increased yield and a lower failure rate across a broad range of sample types, resulting in more usable data and greater consistency for high-throughput workflows relative to SPRQ chemistry. “In our beta testing, we saw consistently strong run performance,” said Adam Ameur, Associate Professor and Senior Bioinformatician at Uppsala University. “The simple workflow, low failure rates, and substantially lower pricing with multi-use SMRT Cells make SPRQ-Nx a practical upgrade for large-scale sequencing projects.” “HiFi sequencing already is well known for a high standard of genomic accuracy, and AI is helping us push that advantage further by improving data quality, speed, and usability while expanding what researchers can learn from each run,” said Christian Henry, President and CEO of PacBio. “With SPRQ-Nx, DeepConsensus, and expanded methylation calling working together, Revio customers can generate more information-rich HiFi long-read data at a much lower cost, creating a stronger foundation for population-scale studies, large disease cohorts, and AI-enabled genomic research.” “The quality of genomic data is determined by the information richness of the sequencer and the refinement of the algorithms that process it,” said Andrew Carroll, Product Lead for Genomics at Google Research. “New advances in DeepConsensus unlock even more of the exceptional quality inherent in HiFi sequencing, empowering scientists and clinicians to find new insights and resolve complex cases of rare disease.” PacBio is also extending AI across the broader genomics workflow, including downstream analysis and interpretation. As population-scale sequencing efforts, national biobanks, large disease cohorts, and AI model-building initiatives generate growing demand for richer genomic datasets, highly accurate HiFi long-read sequencing can play an important role in producing the data foundation needed for discovery. Initiatives such as the Trillion Genes Atlas project further highlight how HiFi sequencing and AI can support large-scale genomic research and future clinical discovery. With SPRQ-Nx now shipping globally, PacBio is making HiFi sequencing more scalable for population-scale genomics, large cohort studies, and research programs that require high accuracy, reliability, and richer molecular information. These improvements are available on existing Revio systems through a software upgrade and new consumable kits. PacBio plans to bring SPRQ-Nx chemistry and other platform improvements to its Vega benchtop system later in 2026. 1 Based on 5,000 genomes per year with applicable discounts.
