Five things from the last 48 hours worth your attention if you build with AI. No fluff.

MODEL
MiniMax says its new Flash model runs agent tasks nearly 3x faster and about 70% cheaper than its predecessor, with a 1M-token context. Pricing is flat: $0.15 per million input tokens and $0.60 per million output. Weights are promised later.
Why builders care: If you tried the free :free variant on OpenRouter, it ends today at 12:00 UTC (7 AM CT). Switch to the base slug minimax/minimax-m3.1-flash so nothing breaks.
AGENTS
Duet is a separate app (iOS, Android, claude.ai) that checks your connected apps every few hours, sends a morning brief, and keeps working on its own cloud computer after you close it. It asks for approval before it sends, pays, signs, or deletes anything. It's waitlist-only for US Pro and Max users.
Why builders care: Its background checks count against your plan's usage limits, which is a useful model for how to budget an always-on agent of your own.
CODING
Flint is a 40B mixture-of-experts model that uses about 2.5B parameters per token. Recursive reports 74.2% on SWE-bench Verified and more than 125 tokens/sec on an M4 Pro MacBook Pro. It's Apache 2.0 on Hugging Face and works with Ollama, LM Studio, llama.cpp and vLLM.
Why builders care: A private, offline coding agent with no usage bill. Compare it with the hosted options in our coding agent guide.
GAME DEV
TheGamer's count of SteamDB data found 2,595 of the 7,145 games in October's Next Fest (over 36%) carry Steam's AI tag, up from just over 19% in June. Players are pushing back, and many of the top-charting demos are AI-free.
Why builders care: Disclosed AI use is now normal on Steam, and players are watching. Being clear about how you used it can help you stand out.
REPO
From MIT researchers: wrap your PyTorch optimizer in one line, and a coding agent (Claude Code by default) watches the run and rewrites the update rule, schedules, and loss-spike guards as it trains. MIT-licensed, with a cost cap you set.
Why builders care: For a new task with no tuned recipe, the authors report it matches or beats the best off-the-shelf recipe across their image and language tests.
