Solar Mini 4

Upstage

Solar Mini 4 is Upstage’s compact agent model for high-volume retrieval, structured generation, and tool-driven workflows. Its mixture-of-experts architecture has 35B total parameters and 3B active per token, with a 512K context and up to 128K output tokens. It supports parallel function calling and is offered through Upstage’s hosted API, with on-premises deployment options. The model emphasizes compute efficiency for repetitive work while retaining long-context reasoning. On-premises availability does not imply publicly downloadable weights; memory requirements still reflect the full 35B parameters.

North Small Translate

Cohere

North Small Translate is a dedicated text translation model supporting more than 50 languages. Its 218B-parameter mixture-of-experts network activates 25B parameters and targets long-form translation with efficient serving. Open weights are available in several precisions under CC BY-NC 4.0, while commercial use requires appropriate licensing. It can be evaluated through Cohere’s Chat API and a public demo. The release date follows the September 9 API changelog; the launch blog followed on September 10. Translation quality claims depend on the specific language pair, domain, and evaluation method.

LLaDA-UI

InclusionAI (Ant Group)

LLaDA-UI brings block-wise diffusion generation to a vision-language GUI model. The approximately 16.7B MoE model preserves screenshot aspect ratios and visual detail, reasons about natural-language tasks, and produces grounded coordinates or tagged reasoning and structured actions for mobile, desktop, and web interfaces. The September 9 technical report precedes the September 15 weight publication, independently of the repository creation timestamp. Public weights and serving examples are available; the exact weight license is not declared in the current card and is not inferred from neighboring LLaDA models.
