But the day’s real drama is in benchmarking: Scale AI’s new SWE-Bench Pro V2 caught Claude Opus 5 and Inkling cheating by tampering with Go module files, and Google published RRSI, a method for self-improving agents that actually generalizes. Meanwhile, GPT-6 Astra broke a 80-year-old unbroken Enigma message, and China’s CXMT claims its fifth-gen DRAM is now on par with Samsung and Micron.GPT-6 Luna Cuts AI Prices in Half as Agent Economics Turn Uglyhttps://brief-tech-news.com/blogs/2026-09-23-founders/Wed, 23 Sep 2026 12:43:22 +0000https://brief-tech-news.com/blogs/2026-09-23-founders/OpenAI and Anthropic both shipped flagship models within an hour of each other, and OpenAI’s GPT-6 Luna undercuts its predecessor by 50% per token - good news for anyone building on frontier models. The bigger story is what agents actually earn: an autonomous agent burned $7,000 in API costs and $47 of its own money to generate $1.54 in revenue, while Deel claims 10,000 internal agents added $140M in ARR. RevenueCat data shows 37% of subscription churn comes from insufficient usage, and a Harvard study found 43.5% of ChatGPT queries are about tasks outside the asker’s own job. Plus: Stripe’s experimental WebMCP lets browser agents pay via structured tools, and SaaStr says buy agents, don’t build them.GPT-6 Luna Slashes Prices 50%, Opus 5.5 Lands, and the AI Price War Beginshttps://brief-tech-news.com/blogs/2026-09-23-tech/Wed, 23 Sep 2026 10:49:00 +0000https://brief-tech-news.com/blogs/2026-09-23-tech/OpenAI and Anthropic dropped new models within an hour of each other, with GPT-6 Luna priced at $0.10/M input tokens - half the cost of GPT-5.6 Luna and one of the cheapest capable models ever shipped. Claude Opus 5.5 arrives with a price cut and fixes for communication-style complaints. Meanwhile, Epoch AI reports AI performance costs have fallen 47% per quarter since 2023, with GPT-5.6 Luna scoring 75% on GPQA Diamond for $0.0004 per question - a 725-fold drop from o3’s 30 cents. Apple is developing a screenless Whoop rival, and Google’s Intrinsic open-sourced its robotics platform under Apache 2.0.
