The October 1, 2026 episode of Catalyst with Shayle Kann on grid-scale batteries in Texas. Per-kilowatt revenue fell from $200 to $30 while the financing bar sits near $100 — and the market says it needs far more storage. A breakdown of the mechanism, the recovery thesis, and where it breaks.

Great for demos and occasional use; for a big batch, renting a card is far cheaper. [Read the full post: A $0 AI App?

Free LLM API vs. OmniRoute, Argued Both Ways: It Depends on What You Send](/en/blog/free-llm-api-vs-omniroute-2026-10/) ## Gooaye (股癌) — EP702 Notes on Gooaye EP702 (3 October 2026): MediaTek capping how much AI its engineers can use, the 65% US bill-of-materials threshold in Morgan Stanley's 1 October optical-module rumour report, October's broad strength in Taiwan, and why quant trading is a different kind of contest.
