SFM beats transformers: 79% length retention
๐กNew SFM architecture crushes transformers on length retention: 79% vs 2%. Transformer killer?
โก 30-Second TL;DR
What Changed
Replaces transformers with Execution, Structure, Meta systems
Why It Matters
Promising alternative for long-context reasoning, potentially enabling efficient local models beyond transformer limits. Early results challenge attention-based dominance.
What To Do Next
Implement SFM's DeltaNet slot bank prototype for your long-sequence reasoning benchmarks.

๐ Enhanced Key Takeaways
- โขState Space Models (SSMs), foundational to SFM-like approaches, achieve linear O(N) complexity versus Transformers' quadratic scaling, enabling 3ร longer sequences like 220K tokens within 24GB GPU memory limits.
- โขSSMs originated from control theory with S4 model introduced by Albert Gu in 2021, evolving through LSSL into practical alternatives for long-sequence tasks like genomics and multi-turn dialogue.
- โขRecent SSM benchmarks reveal representational trade-offs: SSMs preserve early token uniqueness but suffer late homogenization, contrasting Transformers' early oversmoothing and late recovery.
