Latest open artifacts (#21): Open model bonanza! Gemma 4, DeepSeek V4, Kimi K2.6, MiMo 2.5, GLM-5.1 & others. On CAISI's V4 assessment.

The real story here is volume: five flagship open releases in one window means the open-weight tier is now iterating faster than most closed labs can respond to individually. For builders, this is the moment to stop assuming a single open model is your default and instead build eval harnesses that can swap between them cheaply. For investors, the moat argument for closed frontier labs gets harder to make every month this cadence continues.

Introducing Gemma 4 12B: a unified, encoder-free multimodal model

Encoder-free multimodal architectures at a deployable 12B size matter for anyone running local or edge multimodal workloads without the usual vision-encoder tax. If the architecture holds up under real benchmarks, this is a meaningful open-weights option for builders who can't afford API latency or cost at scale. Worth testing against your own multimodal pipeline before committing.
