newsThe week's top AI papers say the harness, not the model, is the variable
DAIR.AI's ten-paper roundup shows scaffolding, not the model, drives the gains: Prime Intellect's Prime Agent lifts ARC-AGI-3 Best@1 from 30% to 95.5%, while a compaction bug quietly erases 90% of safety rules after five rounds.
newsZ.ai's GLM-5.3-Flash: two cheap attentions, MIT weights, and a claim it all ran on Chinese chips
Z.ai revealed OpenRouter's anonymous ox-alpha as GLM-5.3-Flash, a 320B-A18B MIT-licensed MoE that pairs sparse and linear attention to cut KV cache 4.44x, scores 57 on Artificial Analysis's index, and it says was served entirely on Chinese chips.
newsZ.ai says it served GLM-5.3-Flash, OpenRouter's anonymous ox-alpha, entirely on Chinese chips
Z.ai revealed that ox-alpha, the anonymous model that led OpenRouter for six days with 23.2T tokens, is GLM-5.3-Flash, and says it was served entirely on 100,000+ domestic Chinese chips at $0.15/$0.50 per million tokens.
newsChinese labs converge on one architecture: 3:1 linear attention and a 2,048-token budget
Z.ai's GLM-5.3-Flash and Alibaba's Qwen3.8-Flash-Next, released a day apart, independently converged on the same recipe: 3:1 linear attention, a 2,048-token attention budget and four-branch gated residuals, while MiniMax dissents and keeps full attention.
newsAn 11x price spread for the same open-weight model on OpenRouter
Architect CEO Brett Harrison found an 11x price gap between OpenRouter's cheapest and priciest host of DeepSeek V4 Flash — Baidu ran it at $0.049 per million tokens and 124 tokens/second while 26 of 30 rivals were both pricier and slower.
