https://eu-central-1.linodeobjects.com/wagtail-production/images/Frames_skipped_counter_in_application.width-300.png
To detect late frame draws in Qt Quick, measure elapsed time when an item becomes visible and use QQuickItem::ensurePolished to ensure the frame is rendered. Calculate the number of frames dropped by dividing the measured time by the display's refresh rate.

Speculative KV coding: losslessly compressing KV cache by up to ~4Γ—

Speculative KV coding is a lossless compression method for large language model (LLM) caches, using a predictor model to estimate the cache's values and an arithmetic coder to encode the differences. The method can achieve up to 8x compression on original bf16 caches and stacks multiplicatively with lossy quantization.

Arithmetic Without Numbers – How LLMs Do Math

https://alvaro-videla.com/llm-arithmetic-internals/article_interactive/assets/blender_integer_helix.png
A language model can perform arithmetic operations without explicit programming, but the question is whether it recalls a pattern, runs an algorithm, or merely produces a plausible next token. The project Rune found that a language model's internal state can supply operation and operand structure for arithmetic prompts, which can drive a calculator route under an opaque-prompt boundary.
