Overview

Fable 5 is shut down. Claude Code Max is $200/mo. Copilot credits trap is draining cards. Meanwhile a Chinese open-source model dropped on June 1 with a 1M-token context, 59% on SWE-Bench Pro (beats GPT-5.5), and pricing 18x cheaper than Claude Opus — with open weights releasing within 10 days. Here's everything you need to know.

✅ What MiniMax M3 actually is — released June 1, 2026

✅ Real benchmark numbers vs GPT-5.5 / Gemini 3.1 Pro / Claude

✅ The honest pricing math — 18x cheaper than Claude Opus

✅ MSA (MiniMax Sparse Attention) — the architecture trick

✅ Open-weights release — why this matters post-Fable-5

✅ How to drop M3 into your stack via OpenAI-compatible API in 5 min

✅ The 3 honest catches (self-reported benchmarks, Chinese model, no Claude Code support yet)
