CLIMATE SIMULATION AND DOWNSCALING
HiRO-ACEv2
Ai2 system announced on October 14, 2026 combining the ACE2S-X-SHiELD atmospheric emulator with the HiROv2 diffusion model. It transforms roughly 100 km fields into 3 km precipitation, ten-metre wind and sea-level pressure data. The public repository includes both checkpoints, configuration and sample data; its creation on October 12 is not confused with the announcement date. It is not a conversational assistant or a conventional image generator.
15 OCT 2026↗ BYTE-LEVEL BASE MODELBwen 8B
Ai2 checkpoint included in the public release of October 7, 2026, alongside the publication of Bolmo in Nature. It is an autoregressive model that processes text as UTF-8 bytes through local components, dynamic pooling and a global model. The verified modality is text-to-text: potential future extensions to images or audio are not available capabilities. The repository creation date in August is not used as the release date.

03 / METHOD
How to read the directory
An organization, a product, and a model are not the same unit. Inferama separates them to avoid attributing capabilities or commercial terms to the wrong item.
Model
Identifiable version with limits, modalities, and behavior that may change between releases.
Access channel
API, application, associated cloud, or commercial plan; each channel may have different pricing, retention, and limits.
Source and date
Every claim must retain the official page consulted and the verification date.

Bolmo 1B Stage 1 and Bolmo 7B Stage 1: A Local Inference Protocol for Evaluating Byte-Level Representation
A technical analysis of the operational viability of running and comparing Bolmo 1B Stage 1 and Bolmo 7B Stage 1 in local environments. This piece defines a decision framework based on hardware requirements, data isolation, and inference costs, distinguishing between confirmed specifications and metrics that require empirical validation.
