llama.cpp release b9670 includes fixes for NVFP4 edge cases in llama-graph, such as moving post-GEMM MUL operations and restricting build_ffn to supported combinations. The release provides binaries for macOS, Linux, Android, Windows, and openEuler across multiple architectures and backend options, including CUDA, Vulkan, SYCL, and OpenVINO.
llama.cpp version b9665 introduces a new --offline flag for benchmarking. The release includes binary builds for macOS, Linux, Android, Windows, and openEuler across multiple architectures and hardware acceleration options, including Vulkan, CUDA, ROCm, OpenVINO, and SYCL.
We introduce a method to identify agents by their procedural behavior fingerprints, achieving 85.7% accuracy in attributing unseen trajectories to correct agents. Using ProcGrep, we analyze coding agent behavior in SWE-Bench, finding that models from similar release periods or distilled from each other exhibit closer behavioral similarity, with a Jensen-Shannon divergence of 0.25.
ReproRepo introduces a scalable framework using GitHub issues to evaluate ML paper reproducibility. It shows that LLM agents like Codex with GPT-5.5 identify at least one blocker in 90% of paper-repository pairs without executing code, though exact localization remains challenging.
SwiftTrans addresses runtime efficiency gaps in LLM-based code translation by introducing Multi-Perspective Exploration and Difference-Aware Selection. The framework extends CodeNet, F2SBench, and introduces SwiftBench to evaluate runtime performance, showing consistent improvements in both correctness and efficiency across benchmarks.
Current coding benchmarks were designed before agentic software engineering and fail to capture the complexity of real-world systems. They conflate model performance with the entire harness, ignore valid alternative solutions, and lack feedback signals at individual component levels, making iterative improvement difficult.
GameCraft-Bench introduces a benchmark with 140 Godot tasks across 15 game families to assess coding agents' ability to generate playable games. Evaluations show the best agent achieves only 41.46% success, indicating significant challenges in producing complete, interactive games with coherent gameplay and visual feedback.
A model fine-tuned on Qwen3.5-27B predicts PHQ-9 scores from AI dialogue transcripts, achieving MAE=2.6 and AUC=0.91 at the PHQ-9 >= 10 threshold. It maintains AUC > 0.87 across all PHQ-9 severity levels, demonstrating accurate depression severity estimation in real-world conversations without self-reporting.
VoidPadding introduces [VOID] as a padding token to separate semantic termination and response-length modeling. It improves performance on mathematical reasoning and code generation by 17.84 points over the original model and reduces decoding NFE by 55.7% on average.
GLM-5.2 has launched with open weights, a 1M context window, MIT license, and two reasoning modes. Early results show it ranks near the top in coding benchmarks, indicating strong real-world potential beyond API-only models.
Glimmer 1 is a 10,000-parameter language model trained on 500K tokens from FineWeb-Edu. It features a 512-token context window, a standard Llama architecture with 16 hidden dimensions, 2 layers, 4 attention heads, and 1 KV head using GQA, and is available on Hugging Face.
Georgi Gerganov confirms that Qwen3.6-27B is highly capable for coding tasks, noting its daily use on local hardware like M2 Ultra and RTX 5090. He describes using a minimal pi agent with a short system prompt to align it with his workflow, highlighting its utility for maintaining open-source projects.
VibeThinker-3B, scaled from a 1.5B model, reaches frontier-level performance in math and coding tasks. It scores 94.3 on AIME'26, 80.2 on LiveCodeBench v6, 76.4 on IMO-AnswerBench, and 93.4 on IFEval, with 96.1% success on first-attempt LeetCode problems.
DiffusionGemma uses bidirectional attention to allow self-correction during token generation, enabling it to revise earlier tokens in a 256-token block. This capability gives it a structural advantage in generating valid tool calls, as it can correct malformed outputs that autoregressive models cannot fix once committed.
A test comparing Q8 and IQ3 XXS turbo4 quantized versions of Qwen3.6 27B shows that Q8 excels in API safety and input sanitization, while IQ3 XXS turbo4 performs better in thread management and modular code design. The model recommends merging both approaches: using Q8 for initial launch protection and IQ3 XXS for atomic writes and thread lifecycle, forming a combined Phase 1 foundation.
A project called Trace Commons invites users to donate their coding session traces to an open dataset licensed under CC-BY-4.0. The initiative aims to provide training data for open-weight and open-source AI models, countering potential data monopolies by Anthropic and OpenAI.
The user found that N2 Pro, when using Rio's chat template, performs reliably on their 128G Mac. It passed a private benchmark on llama.cpp source code 100% of the time without hallucinations, matching only GPT 5.x in consistency.
A study identifies extrinsic (crucial tokens) and intrinsic (cognitive behaviors) properties that enhance code interpreter reasoning in large language models. Stronger reasoning models show higher prevalence of verification, backtracking, and backward chaining, with these properties improving performance during inference and training, reducing overthinking and boosting token efficiency.
