Anthropic shipped Claude Opus 4.8 — 88.6% on SWE-bench Verified (up from 87.6%) and the strongest computer-use model it has tested (84% on Online-Mind2Web, ahead of GPT-5.5) — while holding the price at $5 / $25 per million tokens, the same as 4.7.

One number → 88.6 %

Specifier · advisor

Budget plus goal in. Three rigs out — every part from our catalog.

The model never quotes a number. Lean, recommended, headroom — streamed in parallel from the same hand-curated spec sheet that builds these pages.

Guides

Job-to-be-done buying advice, tiered by budget. "Local LLM under $4k" rather than "best GPU 2026."

The AI hardware space is loud and young. Reviews are either breathless launch coverage or dry whitepapers. Benchmarks are scattered across GitHub issues, Reddit threads, and vendor marketing. There's no trusted middle ground for operators who need to pick a GPU tier on Monday, a cluster topology by Friday, and an edge device by next quarter.

MadCoolStuff sits in that middle. Not breathless, not academic — the voice of someone who has to actually buy the thing.
