llmspeed estimates tokens per second for 30 machines and 15 models. What its numbers mean, the memory-bandwidth rule behind them, and why prefill matters for coding agents.

DeepSeek V4.1-Flash-1017 jumps 11 points on Terminal-Bench 4.0 at the same deepseek-flash price. Benchmarks vs Opus 5, K3, GLM-5.3 and when to switch.

RTX Spark laptops ship October 16 with up to 128 GB of unified memory. Why the 600 GB/s figure is not memory bandwidth and which local coding models fit.

OpenCode 2 upgrade from v1: what the migration guide says breaks (plugins, server API, TUI config), what carries over, and a safe checklist before you switch.

Mistral Large 4 is a 1T-parameter multimodal MoE with 52B active, in public preview at $0.68/$2.09 per million tokens, with open weights due end of October.

Run Qwen3.8-Flash-Next locally with Strata on a 12 GB GPU: hardware needs, speeds by quant, the license catch, and when the hosted API is the better call.

Opus 5.5 in Claude Code: what each playbook tip changes, from naming the finish line to CLAUDE.md stop rules, and where Hacker News says long runs go wrong.

DeepSeek V4.1 Flash replaced V4 Flash. Official API: $0.15 input, $0.60 output off-peak. OpenRouter hosts start near $0.05. MIT weights are on Hugging Face.

Ox Alpha is a free stealth model on OpenCode with 1M context. What is confirmed, where OpenCode and OpenRouter differ on retention, and how to run it.

GLM-5.3 has no free hosted tier. Cheapest on October 9: Wafer via OpenRouter at $0.049/$3.39, Flash from $0.075/$0.25. Z.ai's promos ended October 7.

OpenAI Codex in 7 minutes: a companion guide to the video tour of the Codex desktop app, plan and goal modes, plugins, multi-agent workflows and UI annotation.

Oak rebuilds version control for AI coding agents with virtual workspaces and branch-per-session flows. Why Git is awkward for agents and what Oak must prove.

GLM-5.2 is an MIT-licensed open-weights coding model. Cheapest routes: OpenRouter hosts from about $0.36 per million input tokens, Z.ai's API, or self-host.

Model routers turn having no single winning model into an advantage: how routing works, why open weights and neoclouds make it cheap, and the counter-argument.
