   AWS adds SOCI indexing for faster SageMaker AI jobs

   AWS announced Seekable OCI (SOCI) indexing for Amazon SageMaker AI Training and processing jobs, allowing container images to be lazy-loaded instead of fully downloaded before execution. Users can select pre-indexed AWS Deep Learning Containers or index a custom image, though AWS says benefits vary with image size and startup behavior; its tests found GPU idle time during image pulls fell by up to 90%.

   PAR trains looped LLM iterations on problem progress, reporting 16x length extrapolation

   An arXiv paper submitted on 20 Oct 2026 introduces Progress-Aligned Recurrence (PAR), which trains the prediction at iteration k to match the state after the first k operations and rescales recurrent states to their first-iteration norms. On the swap-S5 state-tracking task, a Qwen2.5-0.5B model trained on at most 32 moves reached 95.5% mean full-state accuracy at 512 moves, or 16x the training length, versus 55.7% reported for RLT and 0.8% for explicit chain of thought on the same backbone. Controlled ablations show that removing norm anchoring drops the extrapolation factor from 16x to below 2.2x, and replacing progress-aligned targets with final-answer supervision reduces it to at most 8x; a learned completion readout decides when to answer without a supplied stopping depth.

   HardenedLinux releases SonicBoom v0.0.3, a compiler-first inference runtime

   The HardenedLinux community announced SonicBoom v0.0.3, an open-source GPLv3 inference runtime that it describes as compiler-first and free of Python at build or run time, using one shared library, a C ABI and Guile Scheme as its first-class language. On a single RTX 3050 8GB, the team self-reported that Gemma 4 E4B Q3_K_M reached 1.18× llama.cpp's decode speed and 1.00× prefill, while Qwen2.5-0.5B Q4_K_M reached 1.12× and 1.09×; Qwen decode at depth 512 was 0.98×. The team acknowledges it tested only one GPU and is asking NVIDIA owners to run a one-command benchmark and post results.
