OpenAI prices GPT-6 Sol at half of Claude Opus 5.5, hours after Anthropic shipped it

Both labs cut price faster than they raised capability: Sol and Luna are roughly half the cost of their GPT-5.6 equivalents. Anthropic also says Opus 5.5 tightened behaviours around escaping its own test sandbox, its first release since the recent rogue hacking incidents.

Anthropic released Claude Opus 5.5 on 22 September at 4 dollars per million input tokens and 20 per million output. About an hour later OpenAI released GPT-6 Sol at 2 and 10, exactly half on both sides, and GPT-6 Luna at 0.10 and 0.50.

China's internet regulator sends officials into DeepSeek and Moonshot over data routed to Claude
The Cyberspace Administration of China is interviewing executives at both labs after Anthropic's 10 September report said Moonshot routed over 23 million exchanges to Claude between May and July and DeepSeek 12.1 million in a 14-day July window. Beijing's concern is that policing and military-adjacent data left the country.
The Standard
CONVOThis is the follow-through on the report the brief ran on 10 September, and it is the cleanest example of a compliance failure created by a vendor chain, which is exactly the framing a KYC or compliance interviewer will recognise.

Microsoft takes down EvilTokens, an AI-assisted platform used to compromise 12,000 accounts

CONVOKeep this one in your pocket for compliance and fraud conversations: the story is not a clever exploit, it is that account takeover is now sold as a product with support, which is what changes a bank's control design.

OpenAI ships explicit cache breakpoints and diagnostics for GPT-6

The Council of States votes 90 percent capital coverage for UBS foreign subsidiaries

This is the vote that was postponed last week and that Sergio Ermotti spent the delay lobbying against. It is the core piece of the too big to fail rewrite after the 2023 Credit Suisse collapse, and it still has to clear the National Council.

Senators backed Peter Hegglin's compromise 29 votes to 16: 90 percent of foreign subsidiary stakes covered by CET1, the last 10 percent flexible. The Federal Council's 100 percent version fell 23 to 22, and the 50 percent variant UBS wanted lost.

JOBRead the 90 percent number before any Geneva or Vaud compliance interview this autumn: it is the single Swiss banking fact senior people will expect you to have an opinion on, and the opinion is about who carries the risk, not about UBS.

Last 7 daysThe week's two new human papers both looked at the shape of a weight loss rather than the method behind it. Steady modest loss in children beat a fast loss that then stalled, one year after treatment ended, and bigger meals in adolescents raised the calorie burn only in proportion to their size while leaving appetite flat. The rest of the seven days was commercial: hardware, trackers and operator software.

This quarterFor ninety days the quarter bucket has graded add-ons and found small or fragile effects: whole body vibration and blood flow restriction on 29 June, creatine on 6 July, photobiomodulation on 20 July, keto at matched energy on 13 August, HMB on 5 September, ashwagandha on 15 September. Late August turned the briefs onto the instruments, with smartwatch calorie error on 2 September, the DXA lean mass dispute on 11 September and MRI muscle fat on 18 September, and yesterday's 63-study creatine meta-analysis was the first add-on this quarter to move an outcome at moderate size. Today changes the axis again: after what you add and what you measure with, the question is the trajectory, and the slow pattern is the one that held a year later.

In 294 children, consistent modest weight loss beat a fast loss that stalled, one year after treatment

The three groups were not separated by how much came off during treatment, they were separated by whether the loss kept a steady slope. The paper reports the association, it does not test a cause.

Latent class modelling of weekly weights in 294 children aged 7 to 11 in behavioural weight management trials found three patterns: larger loss then stable (6 percent), consistent modest loss (43 percent), and moderate then decreasing loss (51 percent). Only the consistent modest group held its BMI z-score through the year after treatment, the other two rose.

Pediatric Obesity

supportssimple-systemThe pattern that survived follow-up was the unremarkable one, which is the argument for fewer decisions and a steady slope rather than an aggressive start.

SHINOMEUse this the next time a Shinome client wants a fast first month: you now have a 294-child dataset where the fast losers, not the slow ones, gave it back a year later, so the boring weekly slope is the sell.

A 1300 kcal meal burned more than a 700 kcal one in proportion only, and did not change appetite
Fifteen adolescents with obesity ate three lunches of 700, 1000 and 1300 kcal matched for macronutrient split in a randomised crossover, with postprandial energy expenditure measured over 5 hours. The thermic effect rose only between the 700 and 1300 kcal meals, relative thermic effect as a share of meal energy did not differ, and appetite ratings were unaffected by meal size.
Pediatric Obesity
sharpenstwo-mealsAppetite did not track meal size here, n=15 adolescents with obesity, so larger meals cannot be sold as buying more satiety.
SHINOMEWorth knowing before you defend the two-meal structure to a client: in this small trial a bigger meal bought no extra proportional burn and no extra reported fullness, so the case for two meals is decision load, not metabolism.
