1. GPT-4.5 ‘Orion’ launches in research preview, similar quality to GPT-4o
GPT-4.5 slightly outperformed GPT-4o, o1, and o3-mini on SimpleQA, which test models on factual questions, with fewer hallucinations, per OpenAI:
Perplexity’s Deep Research outperformed GPT-4.5 on the same benchmark.
GPT-4.5 also lagged behind OpenAI’s Deep Research and Claude 3.7 Sonnet on the coding-focused SWE-Bench Verified.
“[N]ot a frontier model,” OpenAI initially acknowledged about the GPT-4.5.
Initially for ChatGPT Pro, expanding to Plus and Team next week, and then Enterprise and Edu.
Also available through Microsoft’s Azure AI Foundry.
Sam Altman has said OpenAI staggered GPT-4.5's rollout because it is “out of GPUs”
GPT-4.5 is OpenAI’s most expensive model per token, costing $75/M input tokens and $150/M output tokens
By comparison, GPT-4o is at $2.5/M input tokens and $10/M output tokens.
When it comes to online shopping, two names dominate the battlefield — Temu and Amazon. But what really sets them apart? Omnisend dug into the data, analyzing product listings, pricing tactics, and consumer trust on both platforms.
As a result, they’ve compiled a fascinating look into fierce competition, eyebrow-raising discounts, and growing concerns over brand imitation and fake reviews.
Here’s a glimpse of what they found:
Temu undercuts Amazon on price: Close product matches are 40% cheaper on average, saving shoppers around $13.37 per item
Product overlap is huge: 77% of Amazon-listed products have close equivalents on Temu, and one in 10 are identical
Brand imitation raises red flags: From blurred logos to copycat packaging, Temu products often mimic well-known brands
Discounts run deep: Temu’s slashing prices with up to 98% off in some categories, compared to Amazon’s 67% max discounts
Trust gap is real: Amazon’s review system is robust (50,000 reviews per product on average), while Temu trails behind with just 1,500, plus signs of potential review manipulation
So, who’s really winning — and at what cost?

3. SEC says most memecoins not securities, “more akin to collectibles”
Thu.: the SEC issued long-awaited guidance on memecoins.
The clarification comes after the rapid rise of memecoins following Trump’s comeback.
Dogecoin, tied to the Solana blockchain, is among the top memecoins.
Memecoins are 3-4x more actively traded than Bitcoin and Ether.
