On-policy distillation | Folding EOPD and ToDi into one family

A 33-of-36 result, published with the authors' own asterisk

A four-coefficient family for gating per-token losses in on-policy distillation beats single-channel baselines in 33 of 36 cells. The authors then call their own counts directional evidence and their three-seed replications not significant.

Memory Decoder: a 6.9B bolt-on memory makes a 410M model beat Pythia-12B

Memory Decoder at Scale splits long-term memory from reasoning in LLMs. A 6.9B pretrained memory lifted Pythia-410M past Pythia-12B on 17 benchmarks with 39% fewer parameters; 1.7B domain memories added 9+ points to Qwen3 Base at every scale tested.

Competitive programming

NousCoder-14B just opened the coding RL black box that OpenAI and DeepMind keep locked

Nous Research drops NousCoder-14B, a 14B competitive programming model with a fully open RL pipeline. The 68% Codeforces solve rate is notable, but the real story is that anyone can now replicate the stack.

Long-context LLMs

Jet-Long's bifocal attention just killed the fixed-scaling trade-off for long-context LLMs

Jet-Long adapts RoPE rescaling dynamically per sequence length, using a local window and a long-range window merged via inclusion-exclusion. On Qwen3 models up to 128K context, it beats existing zero-shot baselines by over 2 percentage points on RULER and achieves the lowest perplexity on PG-19, all while adding less than 4% generation overhead.
