Social ran on one story: the US shutting down Anthropic's best models, with open-weight rivals circling the gap.
Today's signal
- Dominant story: the Fable 5 / Mythos 5 shutdown, debated live from Anthropic's Build Day.
- Pattern: builders and creators frame it as US labs handcuffed while China stays free.
- Counter-signal: open-weight models (MiniMax M3, Kimi K2.7, Rio-3.5) pitched as the real winners.
- Quiet area: no curated research reposts, no Reddit signal, no fresh paper buzz.
- Cross-source: video and tweets both push MiniMax M3 as the open-frontier coder.

MiniMax M3: sparse attention as the open-frontier play
- Video pitches M3 as 1M-context, multimodal, 10-20x cheaper than Opus.
- Sparse Attention (MSA) is the named mechanism behind cheap long context.
- Tweet thread: M3 and Rio-3.5-397B filling the gap Qwen3.7 left.
- Creators frame M3 Code as a 24/7 multi-agent "digital employee" harness.
- Wiki already covers the MSA paper behind M3's efficiency claim.
LLMs, agents, safety
The Fable 5 / Mythos 5 shutdown
- US gave Anthropic 90 minutes to disable both models worldwide.
- Reported trigger: a rival's jailbreak demo, not China.
- Anthropic disputes the White House timeline; says it replied in 75 minutes.
- Scoble from Build Day: builders loved Fable, forced back to Opus 4.8.
- Recurring line: US labs handcuffed while China stays unconstrained.
Small models and the train-big-then-distill debate
- HF's @eliebakouch: Chinese labs build strong small models without distillation.
- Mistral competes on European + open-weight, not frontier capability.
- Cursor's @ellev3n11: training codebases tuned for many small runs.
- YC roundup video: SGS self-play lets 7B match 671B on formal reasoning.
Industry and business
- Anthropic shutdown spirals: no investor publicly backs Dario, IPO doubts raised.
- OpenAI under criminal probe and multi-state subpoena while filing for IPO.
- Open coder Kimi K2.7 undercuts GPT-5.5 and Claude up to 12x per token.
- European politicians discover dependence on US models only after the cutoff.
- Voice cloning in seconds (everlife.one) demoed as a "digital you" tool.
