Heaps do lie: debugging a memory leak in vLLM
Mistral AI News50 days agoTutorialMistral AI published an engineering deep dive on a memory leak found during vLLM disaggregated serving tests. The leak appeared only with a specific stack involving Mistral Medium 3.1, NIXL, UCX, graph compilation, and P/D disaggregation, with RSS growing steadily despite heap profilers looking normal. The team used pmap, BPFtrace, and targeted GDB automation to trace the issue to UCX mmap hooks and applied configuration fixes plus a vLLM patch.

Rails testing on autopilot: Building an agent that writes what developers won't
Mistral AI News50 days agoTutorialMistral AI describes an autonomous Rails testing agent built on its open-source Vibe coding assistant. The agent reads Rails files, applies file-type-specific skills, generates or improves RSpec tests, and validates them with RuboCop, RSpec, and SimpleCov. In a 275-file experiment, it reached 100% passing tests, 100% average line coverage, zero RuboCop violations, and a higher LLM-as-a-judge score, while stressing that generated tests must actually run.

Arithmetic Without Numbers: How LLMs Do Math
Hacker News (AI keywords)53 days agoCommentaryThe article asks whether LLM arithmetic is memorization, heuristics, real computation, or experimental assistance. It summarizes Rune experiments that decode operations and operands from frozen Llama activations, then route them to Python under a no-parser rule. The strongest supported claim is narrow: activation-derived tool arguments worked in scoped audits, while residual-state JIT replacement, long-number generation, and cross-model transfer remain brittle.
How LLMs Actually Work
Hacker News (AI keywords)54 days agoTutorialThe article explains how modern LLMs convert text into token IDs, embeddings, and position-aware vectors before passing them through stacked transformer blocks. It covers attention, multi-head attention, KV cache, GQA, feed-forward networks, MoE, residual streams, normalization, and decoding. Its goal is educational: helping readers understand the common architecture behind many current model families and read model cards or papers more confidently.
