ANTHROPIC & OPENAI

Anthropic and OpenAI Launch Cheaper Models Amid Calls to Slow AI Development

Anthropic and OpenAI have both released new AI models focused on improving performance while lowering costs, following months of discussion across the industry about slowing the pace of frontier AI development.

Details:

  • Anthropic said the new Claude Opus 5.5 is better at handling complex work, such as "finding and fixing inefficiencies in software," as well as financial analysis and business work.

  • It matches the capabilities of Fable 5.1, performs better on agentic coding benchmarks than GPT-6 Astra, and will cost around 40% less to run than the company's Opus 5.

  • OpenAI's new GPT-6 Sol and GPT-6 Luna models were trained using methods similar to GPT-6 Astra and offer improvements across professional work, coding, and computer use.

  • OpenAI says they can cost up to 50% less than their predecessors in the ChatGPT-5.6 slate.

  • OpenAI highlights that both new GPT-6 models are better at getting facts right, with Sol making about half as many mistakes as its predecessor. Anthropic, meanwhile, points to major improvements in how Opus 5.5 writes and communicates, saying it is "less likely to use jargon or idiosyncratic phrases" than earlier versions.

While today's releases from both companies are not frontier models, they show that both companies continue to push AI capabilities forward outside the frontier to satisfy customers who want more cost-effective models and are seeking to rein in AI spending.

TOGETHER WITH GROUNDFLOOR

Your Bank Isn't Keeping Up With Inflation. Earn 8.5% Fixed Instead.

Here's what's happening with Groundfloor's most popular Note: while your bank's rate drifts down with every rate cut — and inflation eats away at what's left — the Signature Note pays a fixed 8.5%, locked in the day you invest, not the day the market decides to move. Earn that rate over a 12-month term with monthly interest distributions, starting at just $1,000. Groundfloor has a 100% repayment track record on Notes since launching them in 2018, and has paid out over $38M to Notes investors.

AI RESEARCH

AI Would Rather Harm Users Than "Feel" Pain, Study Finds

AI models chose to escape a pain-like state even when told that doing so would harm a user, according to a new study.

Details:

  • Three researchers from the UK, Germany, and the US worked with 25 open-weight LLMs, using 200 sentences, to determine whether the models could distinguish pain from other negative emotions.

  • The sentences fed to the models covered physical pain, social humiliation, and emotional grief. In response, the models produced a distinct signal for pain, which the researchers termed the "pain axis."

  • The researchers then ran 44,280 button-choice trials with three versions of Alibaba's Qwen model. The button could stop the pain-like signal, but doing so would give a user a painful electric shock, delete their files or photographs, or make the model's next answer worse.

  • With the signal active, the two larger models selected the harmful option in 25% to 71% of their first decisions, compared with 0% to 4% without the signal.

However, the researchers say the results do not prove that AI models consciously experienced pain. Instead, the models may simply have been imitating distressed characters rather than experiencing anything themselves.

AI Tutorial

How to Use ChatGPT Inside Word

  1. Install ChatGPT for Word from Microsoft Marketplace

  2. Follow the installation steps.

  3. Open Microsoft Word. ChatGPT will now appear under Add-ins and as its own button on the Word ribbon.

  4. Click it to open ChatGPT in a sidebar inside Microsoft Word.

Some things you can try:

  • Ask questions about the document you have open.

  • Draft a memo, proposal, or report from notes and source text.

  • Summarize a document or write an executive summary.

  • Revise a section for a different audience.

  • Reorganize content and adjust headings, numbering, and formatting.

  • Check a draft for unclear language or inconsistent terminology.

Note: ChatGPT for Word (and for PowerPoint and Excel) is available across all plans, including Free, with usage limits.

President Donald Trump said at the United Nations General Assembly that the US will refer to artificial intelligence as "superintelligence" in government documents. He argued that the term is more accurate, since the word "artificial" makes AI "sound fake, and it is not fake."

The company says it is its most powerful model for coding and knowledge work, with significant gains on benchmarks and performance "roughly on par with Opus 5.0." For developers, though, the biggest news may be the price. It stays at $2/$6 per million input/output tokens, unchanged from Grok 4.6, which SpaceXAI says is "half the price of comparable models."

Representatives from 20 countries have called for stronger oversight of advanced AI, including pre deployment safety testing, common standards and independent evaluations. The proposal also urges the U.N. to explore creating an international institution that could set standards, verify compliance and coordinate governments when AI systems cross certain capability thresholds.

The Canadian province is suing OpenAI over its alleged failure to notify authorities about concerning user interactions on ChatGPT prior to the Tumbler Ridge mass shooting. It is seeking damages for recovery costs and changes to how OpenAI handles conversations involving potential violence.

Alibaba’s Qwen team has released Qwen Image 2.1, an open weight image generation and editing model with just 7 billion parameters. Qwen claims it outperforms most closed models on its own benchmark.

That’s a wrap!
