Unsloth’s Dynamic GGUFs make Gemma 4 12B…

Google’s Gemma 4 12B is multimodal with a 256K context window. Unsloth’s Dynamic GGUFs squeeze a usable 4-bit build into roughly 8GB of memory without throwing quality off a cliff.

vLLM + Mooncake share KV cache across…

Agent traces reuse huge prefixes turn after turn. Mooncake Store gives vLLM a distributed KV pool: 3.8x throughput, 46x lower TTFT, and near-linear scale on GB200 clusters in vLLM’s report.

China's 582-tonne fusion magnet is heavier than…

The Institute of Plasma Physics accepted a toroidal field coil for China's CRAFT fusion program that is 1.3 times the volume of ITER magnets and stores three times the energy. Full-load testing passed in Hefei. Fusion power by 2030 is still a bet, but the hardware stack is real.

Every population may carry DNA from a…

A Science study analyzed 503 modern genomes with a new TRACE model and found archaic ancestry that matches no known Neanderthal or Denisovan sequence in every population tested. Roughly 0.5 to 1 percent of non-African genomes may come from a branch that split off more than 500,000 years ago.
