The model helped scientists by simplifying expressions and made a simple formula for this general case.
Then it spent nearly 12 hours reasoning the new problem, verifying the formula and «producing a formal proof.»

The drawback is that it’s text-only and only has a 128K context window, and it’s supposed to be used «where latency matters as much as intelligence.»

But now, Claude can create and manipulate Office files and PDFs for free.
Connectors are also available, which make it possible to link to Slack, Canva and others.
Anthropic is also making Skills free. These are saved prompts and workflows as a kind of template, that can be invoked at any time for repetitive tasks.
Finally, «Compaction» is becoming available on the free tier, which «summarizes earlier context automatically, so long conversations can continue without starting over.»
Together, these comprise «Claude’s most-used features,» Anthropic says.

Codex is now rolling out to all engineers at the company, in close cooperation with the OpenAI team who built in «cloud-managed admin controls» and fail-safe processing.
They even helped onboard the Nvidia team, saying «It’s shocking how quickly they’ve adopted Codex», and that they move like a giant startup.
GPT-5.3-Codex was only launched last week, and is perceived as a possible profit engine, competing with Claude Code for enterprise customers.
ByteDance has been known to work with US chip producer Broadcom, and started seriously hiring chip specialists in 2022.
The new chips are set to be produced with Samsung in a deal that includes memory chips, which definitely sweetens the deal.
Production is advanced enough that Reuters’ sources say engineering samples are due by late March, which is the last stage before production.
A spokesperson for the company does not deny the report outright, but claims the information is «inaccurate,» Reuters writes.
Most US frontier labs are developing their own chips, as is Alibaba and Baidu.

The Cowork agent app was previously only available as a research preview on the Mac, but it’s now out on Windows for all paid tiers.
The agent lets you create summaries and manipulate files on your computer, and can access Slack, Google Calendar and Office files.

Meta banned all AI chatbots other than Meta AI from WhatsApp on January 15th, and while the EU can take a long time to investigate antitrust allegations — they are considering issuing an early order to «avoid Meta’s new policy irreparably harming competition in Europe,» says Teresa Ribera, The EU’s Executive Vice-President for Clean, Just and Competitive Transition.
WhatsApp has over 3 billion users worldwide and qualifies as a gatekeeper in EU parlance, subject to rules on equal access.
Meta says that «There are many AI options and people can use them from app stores, operating systems, devices, websites, and industry partnerships,» in a statement to Reuters.
The process following this formal notification is that parties can examine the EU’s files, reply in writing and then receive a hearing. After that, the Commission will consider «interim measures,» such as restoring access for competitors, even as the case moves forward in their systems.

That would likely be GPT-5.3, debuted last week for Codex. It’s a blazingly fast and more capable successor to 5.2, and is said to be one of the first models used to make itself.
The new Codex model has been a great success, funneling a 60% growth in overall use just last week.
That model is also available to Free and Go users for a limited time, and is now being extended with perhaps reduced limits, Altman says:
— We want everyone to be able to try Codex and start building.

— Our goal is for ads to support broader access to more powerful ChatGPT features while maintaining the trust people place in ChatGPT for important and personal tasks, they write.
Paid tiers other than Go won’t be seeing any ads at all, and the stated reason for them is to give more queries and responses to the ad-supported tiers, while keeping them fast and responsive.
It’s possible to turn off ads and get limited messages, and under-18s won’t be getting ads. They will also be disabled for «sensitive topics» such as health, mental health and politics.
The test is only for the U.S. market as it stands, and the plan is for ads to make up a little less than half of OpenAIs income once they get off the ground, CNBC reports.

Our teams have been building with a 2.5x-faster version of Claude Opus 4.6.
We’re now making it available as an early experiment via Claude Code and our API.
— Claude (@claudeai) February 7, 2026
For «work like rapid iteration or live debugging» Anthropic is letting users go fast, by toggling «/fast» on their console.
The feature is available in a «limited research preview» in the API for paid users with «extra usage» enabled, and there is a waiting list to get on it.
It’s the same model with the same capabilities and there is no change other than the speed — and cost.
The price for using fast mode is $30 for input and $150 in output for a million tokens, but there is a 50% discount until February 16.

If you haven’t caught up yet, Anthropic has sworn off ads and are using their Super Bowl to time decry them.
This has caused a very real spat with OpenAI, and Sam Altman posted a long screed about how Anthropic is misrepresenting how ads will work in ChatGPT.
GPT-5.3-Codex is here!
*Best coding performance (57% SWE-Bench Pro, 76% TerminalBench 2.0, 64% OSWorld).
*Mid-task steerability and live updates during tasks.
*Faster! Less than half the tokens of 5.2-Codex for same tasks, and >25% faster per token!
*Good computer use.— Sam Altman (@sama) February 5, 2026
The new coding model is 25% faster — letting it do long-running tasks in a shorter time frame.
It’s the first OpenAI model that was built with itself. They used early versions of it to debug, manage deployment and diagnose test results, and say they were impressed with its capabilities.

It should be better at doing everyday tasks, and along with upgrades to Claude in Excel, Anthropic is also launching Claude in Powerpoint in beta with this release.
It also supports «agent teams,» letting you «spin up multiple agents that work in parallel as a team that coordinates autonomously.»
Opus 4.6 was also built by Claude, in what seems to have become an industry standard to use their own coding tools for new models. GPT-5.3-Codex was built in a similar manner.
As for benchmarks, it beats most frontier models on almost every one of them. It scores 65.4% on coding-level Terminal-Bench 2.0, and does 68.8% on the difficult ARC-AGI-2, and 53% on Humanity’s Last Exam for general reasoning.
Also new with this model is the advent of «Adaptive thinking,» which lets Claude itself decide when to use deeper reasoning, and different «Effort»-levels for each query, set by users, which could save a few tokens.
