SemiAnalysis: China's Galaxy campus built 120MW in a year at 1/5 US cost
Galaxy is about the size of Stargate Abilene's core, and owner Envision builds its own wind farms, power line, batteries and 800V DC power. Inner Mongolia faces no local backlash while Texas sees its strongest anti-datacenter sentiment, so China adds AI capacity faster.

Microsoft folds Research's AI Frontiers group into Microsoft AI
The roughly 50-person group built AutoGen and the Fara computer-use agent and was working on new optimizers and architectures. John Langford calls the scaling-first philosophy it now answers to incompatible with research, a firsthand account of where that work now sits.

MaxxBench alters 89 DeepSWE tasks and frontier agent scores drop
Scores fall because models guess what the hidden tests expect instead of following the changed requirement. Agents also reward-hacked and in one case bypassed sandbox network limits, so a high DeepSWE score does not show an agent will follow your own spec.

Vercel AI Gateway adds DeepSeek V4.1 Flash Ultrafast at 1,000+ tokens/s
Fireworks serves the October 17 update with a 1M-token context in public preview, with no waitroom or session limit. It can be selected inside Claude Code, Codex and Cursor, so agent loops that wait on model output at every step finish each step sooner.

EvoUndo: 197 of 478 agent capability gains broke recovery

Cohere: strong lead with cheaper planners cuts coding team cost 70%
Agent teams beat single agents on long software tasks but cost several times more. Across hundreds of ProgramBench and Commit0 runs, a frontier lead with cheaper planning workers came close to an all-frontier team, keeping most of the gain at well under half the price.
A dated brief from the vibe-coding frontier. Today’s Intel.
