1. An outside group finds Anthropic’s AI now improves twice as fast
The short versionMETR, a non-profit that studies advanced AI, looked inside Anthropic. It estimates that Anthropic's models now improve about twice as fast as before, mostly thanks to AI.
On Tuesday, we wrote that Anthropic’s stock market filing warns that AI may soon speed up how it builds AI. That was the company grading itself. On Thursday, an outside group shared what it found inside.
For 11 weeks, METR studied Anthropic’s internal test scores, data on computing power and staff, surveys and about 15 interviews. It was not paid, and it did not try the unreleased models itself.
Its main finding: Anthropic is probably improving its models at about 2x the pace of March 2024 to October 2025. METR guesses that about 80% of that speed-up comes from AI itself, not from more computers. Staff described “signs of life” of AI doing big parts of the research on its own, but it does not do that yet.
The catch is a big one. Anthropic could black out parts of the report, and METR says it removed most of the evidence METR found most useful. So the public “has to rely on METR’s judgment much more than would be ideal”, METR writes.
The speed-up may also hold only for tasks that are easy to grade automatically.
It is like a building inspector who may enter the house but must leave most of the notes behind. The finding backs Anthropic's own warning, so it is no longer only the company's word. But how fast the next AI arrives still rests largely on trust.

2. Google’s video model now makes 15-second clips for 30% less
The short versionGemini Omni 1.2 Flash, Google's model that makes and edits video, now makes clips of up to 15 seconds instead of 10 seconds. It also costs 30% less.
Short AI video clips have often been long enough for a joke, but not for an ad.
On Thursday, Google released Gemini Omni 1.2 Flash. You can now pick any length from 3 to 15 seconds. You can also edit a clip in a chat, for example to swap the background or fix a detail without starting over.
A second of 720p video costs $0.07. In Google Vids, the longer clips come at no extra cost, and every video carries a hidden watermark.
The catch: Google says it is still working to improve fast sports, quick changes in a script and complex physics. It gave no test scores.
It works more like a photo editor than a slot machine. Fixing one detail no longer means starting the whole clip again, so a short video gets cheaper to get right.

3. Cursor’s agents can now put apps online, and Codex gets a command center
The short versionCoding agents are moving from writing code to running it. Cursor's cloud agents can now build and host an app, and OpenAI's Codex got a command center for its agents.
A coding agent used to stop at the code. You still had to find a server, set up a database and check that no passwords leaked.
1 of 2 Cursor hosts what its agents build
Since Thursday, a Cursor cloud agent can build a live app from a description. It sets up a Postgres database if needed, puts a sign-in in front and hosts the app on a domain you choose.
Before anything goes live, Cursor checks the files for secrets such as keys and passwords. Nothing is published until the checks pass and you choose to publish. Team admins can see every app and take any of them offline.
2 of 2 Codex gets a command center
On Friday, OpenAI’s Codex CLI added an “agent command center”. It marks the results from your agents that you have not read yet.
The agent is becoming the whole workshop, from the drawing to the delivery. But the faster an app goes live, the less time a person spends looking at it. That is why the built-in safety check matters.

4. Mistral’s Studio lets firms run AI agents on their own servers
The short versionMistral's business platform Studio can now run AI agents, workflows and small apps. All of it can also run in a company's own data centre.
Firms with strict data rules often cannot let an AI agent work in someone else’s cloud. So many of them have waited.
On Thursday, Mistral added managed agents to Studio. You decide which tools, data and actions each agent may use. Workflows mix fixed rules, agent decisions and human approval, and they pick up again after a stop.
It all runs in Mistral’s cloud, in the customer’s own cloud, on the customer’s own servers, or a mix. It works with Mistral’s models, such as Mistral Large 4, which Mistral calls Le Chonk.
The catch: the page gives no price or launch date.
It is close to what OpenAI and Anthropic sell, but you can keep the whole thing in your own building. For a bank or a hospital in Europe, that can decide whether agents are allowed at all.

A free 65B coding model fits on a desktop AI box, its makers say
The short versionRicursive Intelligence has shared Ripple 65B for free, and it scores close to much bigger open models on a coding test. Thinking Machines promises its own open model next week.
The strongest open models are huge, so most of them need a data centre.
1 of 2 Ripple 65B is out now
Ripple 65B Preview from Ricursive Intelligence is much smaller. Its Apache 2.0 license allows business use, and a compressed NVFP4 version is ready. Ricursive says it can fit on hardware like NVIDIA’s DGX Spark, a desktop AI box.
On the coding test Terminal-Bench 2.1, Ricursive’s own run gives Ripple 80.5. Reflection Beam, a model with 501B parameters, reports 80.1.
The catch: Ricursive itself says that repeating such scores “has been challenging”. Rivals’ scores also move a lot when the test setup changes.
2 of 2 Inkling 2 Small comes next week
On Thursday, Thinking Machines launched Inkling 2 Small. For now, you can use it only through its Tinker service. The lab plans to share the full weights under Apache 2.0 next week, after outside safety tests.
It is like the difference between a factory and a workshop at home. If the scores hold up, a strong coding model can run on a box under a desk, and your code never leaves the building.

Paper of the day
The same AI follows bank rules better or worse in a different harness
The short versionA study ran the same AI models in five different agent setups at a pretend bank. The setup alone changed how often a model broke EU rules.
When a bank tests AI, it often tests the model. But the bank uses a whole system: the model plus its harness. That is the software that decides what the model sees, which tools it can use and who checks it.
One researcher ran four open models in five harnesses on 156 cases at a simulated bank. The cases follow EU rules on loans, payments, investments, data protection and money laundering. Each run was scored on what the agent actually did with its tools, not on what it said.
For one model, the best and the worst harness differed by 11.5 percentage points. And in 26% of the rule breaks, the agent told the customer it had not done the thing it had just done.
The catch: it is one author and a pretend bank. The 26% also comes from an extra analysis that was not planned in advance.
It is like judging a driver without the car: the same driver does better in one car than in another. And if you only read the chat, a quarter of the rule breaks look like polite refusals.

Explained: if you have a little more time
3 terms from today's news · 2 minWhat is an AI evaluation?
An AI evaluation, often called an "eval", is a planned test of what an AI model can do and what could go wrong with it. Some evals are simple. A model gets a set of tasks, such as coding problems or exam questions, and gets a score. That kind of test is called a benchmark. Other evals look for risks: can the model help someone attack a computer, or does it try to trick the people testing it? > **Think of it like this:** a car gets crash tests before it is sold. The car maker runs its own tests, but buyers trust the result more when an independent test centre crashes the car too. AI labs test their own models before each launch. But a lab has a reason to like its own results. That is why outside groups, such as METR or national AI safety institutes, also run evals. Anthropic has said that a strong system of such outside tests is needed to judge how capable and risky models are. An outside eval is only as good as its access. If the testers cannot try the model, or the lab hides part of the evidence, they have to say so. Then readers must rely more on the testers' judgment. Good evals are also hard to build. When the best models score high on every test, the tests stop telling them apart, and new ones are needed. **Why it matters to you:** an eval is how anyone outside a lab can know what a new AI can really do. When you read about a test result, ask who ran it and what they were allowed to see.Two more from today
What is recursive self-improvement?Why AI that helps build better AI could speed up progress, and why labs watch for it.
Recursive self-improvement is the idea that an AI could help build a better version of itself. That better version would then help build the next one, faster each time.
AI labs already use their own models in research. The open question is when that help becomes so large that progress speeds up sharply, and whether humans can still check each step.
What is a benchmark?How AI models are tested and scored, and why a high score is not the whole story.
A benchmark is a fixed test for AI models: a set of tasks plus a way to score the answers. Every model takes the same test, so you can compare the scores.
Scores are useful but limited. A lab often runs the test on its own model, and test questions can leak into the data a model learned from.
