GLM-5.3-Flash ships 320B parameters in a 328 GB native-FP8 checkpoint, so the 18B active count tells you nothing about the memory you need. Here are the real hardware requirements by quantisation, plus working vLLM, SGLang, llama.cpp and Apple Silicon setups.

Z.ai's GLM-5.3-Flash is the model that ran anonymously as Ox Alpha: a 320B-total, 18B-active natively multimodal MoE with a 1M-token context and MIT open weights. Here are the verified specs, pricing and benchmarks.

Ox Alpha was Z.ai's GLM-5.3-Flash, confirmed on 26 August 2026. The free stealth preview has ended and the OpenRouter listing is gone. Verified specs, MIT-licensed weights, real pricing, and how to use the model now.

Hardware virtualization is the CPU feature that lets Android emulators, Docker, WSL 2 and Hyper-V run at native speed. Here's what VT-x and AMD-V actually are, how to check whether yours is on, and what to do if it isn't.

Verified Grok 4.6 API and subscription pricing as of 23 August 2026 - the $2/$6 token rates, the 200K long-context cliff, per-call tool fees, and worked cost examples.

Claude Opus 5 leads on independently verified coding benchmarks; Kimi K3 costs 40% less and ships open weights. A head-to-head on benchmarks, cost, context, openness and speed — with an explicit decision rule.

Kimi K3 costs $3 per 1M input tokens, $0.30 on a cache hit, and $15 per 1M output — flat across the full 1M-token context. Here are the verified rates, the rate-limit tiers, three worked cost examples, and how it prices against Claude Opus 5, GPT-5.6 and DeepSeek.

Gemini 3.7 Flash is Google's best available model as of August 2026. Intro pricing, independent benchmarks, and whether you should switch.

Qwen3.8-27B posts benchmark wins over Claude Opus 4.6 Max and ships a first-party Claude Code launcher via Ollama. We grade the claims, fix the overthinking latency problem, and redraw the hybrid local-vs-cloud line.

The 17GB Apache-2.0 model scoring 52 on Artificial Analysis: which benchmark numbers to trust, the overthinking fix, VRAM needs, and how it compares to Claude and the 2.4T flagship.

Run Qwen3.8-27B on your own GPU: Ollama one-liner, LM Studio, llama.cpp with MTP speculative decoding, VRAM tables, tested 16GB/24GB/Mac configs, and the overthinking fix.

The config.json diff between Qwen 3.8-27B and Qwen 3.6-27B is empty — same layers, same hidden size, same vocab. Every gain came from post-training. Here's what actually changed, what the upgrade costs you, and who should stay on 3.6.

GLM-5.3 claims 2,436 real vulnerabilities found — and FreeBSD and Red Hat CVEs actually credit the model line. What verifies, what doesn't, and the licence question that matters most.

GLM-5.3 launched August 14, 2026 with big coding claims and cyber capabilities. The API and independent benchmarks have since arrived — the weights haven't. What shipped, what's verified, and whether to wait.

DeepSeek V4-Pro hit general availability on August 13, 2026. It ranks #2 on SWE-bench Verified at 1/36th the cost — and last of seven on agentic coding. The split is the story.

DeepSeek moved to peak/off-peak billing at 16:00 UTC on August 16, 2026. V4-Pro output rose up to 4.55x and cache-hit input up to 12x. Full rate tables, the peak windows, and how to cut costs under the live pricing.

Alibaba's Qwen3.8-Max is a 2.4T MoE with a near-MIT licence and elite algorithmic coding. But its agentic benchmarks reverse under a neutral harness, and you can't run it locally.

xAI's Grok 4.6 numbers verify cleanly — but the Terminal-Bench version trap, a stale official leaderboard and a 2.3x cost-per-task rise make them easy to misread.

Grok 4.6 improves coding and reasoning but regressed on agentic coding, tripled time-to-first-token and costs 2.3x more per task despite an unchanged price list.

Grok 4.6 launched August 12, 2026. Specs, the 200K pricing cliff, the Terminal-Bench version trap, and an honest read of where it beats and loses to Claude Opus 5 and Muse Spark 1.2.

Meta released Muse Glimmer on August 10, 2026: 30B parameters, Apache 2.0, 128K context, runs under 20GB at 4-bit. Specs, honest benchmarks and how it compares to Qwen 3.6 and Gemma 4.

Five days after launching a closed paid coding agent, Meta shipped a 30B Apache-2.0 model and announced it will open-source Muse Spark 1.2. What changed, and what it means if you build on these models.

Meta's Muse Code launched August 5, 2026. A head-to-head against Claude Code on benchmarks, pricing, parallel agents, sandboxing and ecosystem — including why Meta's own numbers favour Anthropic.

Meta launched Muse Code on August 5, 2026. What it is, how to install it, what Muse Spark 1.2 costs, how the sandbox and subagents work, and whether the benchmarks hold up.
