Conference on Next Generation Arithmetic (CoNGA) is the leading conference on emerging technologies for computer arithmetic. The demands of both AI and HPC have led the community to realize that something better than traditional floating-point arithmetic is needed to reach the speed, accuracy, and energy-efficiency that are needed for today's most challenging workloads. Posit arithmetic is achieving rapid adoption as a non-proprietary format based on the most stringent design principles. At the same time almost daily we see a multitude of new papers reporting on reduced or mixed precision arithmetic, algorithms and hardware implementations based on an obsolete and provably inferior number encoding standard. CoNGA welcomes papers about any arithmetic format that breaks from the past and shows merit and promise.

There is no conference registration fee.

Call for papers and workshop topics
-----------------------------------

*Posit & Valid Arithmetic
*Artificial Intelligence Data Formats
*Energy Efficient Arithmetic
*Right Sizing Precision

We also invite proposals for reports and presentations/tutorials on the following topics:

*Posits libraries and other number coding libraries
*Hardware projects
*Exploring new applications
*New and interesting use cases
*Standardisation efforts
*Why mixed precision effort is a dead end

Paper submission details
------------------------

Submission and review of papers for CoNGA'26 will be managed via the online conference paper management system, OpenReview. This system gives the author flexibility over the paper submission. Authors can upload their papers and check on the review status of their submissions.

The corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to the publisher, changes relating to the authorship of the papers cannot be made.

Papers should present original research and should provide sufficient background material to make them accessible to the broader community. It should not be submitted in parallel to any other conference or journal. All manuscripts will be reviewed and judged on correctness, originality, technical strength, and significance, quality of presentation, and interest and relevance to the conference.

At least one author of an accepted paper should be available to present the paper at CoNGA'26 (16 November 2026, Chicago, IL, USA) in person. For more details on the CoNGA'26, please visit https://posithub.org/conga/2026/
