New on our Engineering blog: Creating in-house source control.
In May, we merged around 2,500 code changes per day. In September, we merged more than 30,000 per day. As a result, we became bottlenecked by developer infrastructure built for human (rather than agent) scale.
Here, we share how we built a new version control systemβand fully migrated our monorepo from gitβin five months: anthropic.com/engineering/reβ¦

Opus 5.5 performs at the level of Fable 5.1. It's ~30% faster and ~40% cheaper than Opus 5 per task.
In Claude Code:
- 5-hour session limits increase 20% today
- Opus 5.5 is priced lower, so it goes 25% further within limits
- Pro, Max, and Team users get a reset to use anytime
Estamos tan absorbidos por los chatbots que no nos damos cuenta que hay otras formas de usar la IA
Un enfoque distinto permite tener modelos mucho mΓ‘s eficientes y econΓ³micos por el simple hecho de no ser conversacionales
After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?
Iβve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev
β’ 20-200x faster
β’ 40-400x cheaper (w/ output tokens free)
β’ Frontier composable intelligence optimized for decisions
AFAICT the shortest path to AI-based economic revolution

Met a guy making $1.1 million a year as an agents engineer at Google Cloud.
Asked him how he gets agents 20x better without changing the model.
He sent me the exact thing he uses himself. A repo he open-sourced 2 days ago.
You won't find anything better about harness engineering, in the open.
Cloned it and pointed my agent at it last night.

Al fina han tomado una decision, ya era hora
Beginning July 20, Claude Fable 5 will be included in all Max and Team Premium plans, at 50% of limits.
Pro and Team Standard users will continue to have access to Fable via usage credits, and will receive a one-time $100 credit.
Demand for Fable has been challenging to predict, which is why we rolled it out to subscription plans in stages, extending access several times as we secured additional capacity.
La mejor idea no apareciΓ³ buscando una startup. ApareciΓ³ comprando un coche.
Mi proceso fue mΓ‘s o menos asΓ:
Buscaba coches en 3 marketplaces diferentes.
Configuraba alertas en todos.
Cada dΓa revisaba decenas de anuncios nuevos.
Guardaba los mΓ‘s interesantes en favoritos.
Me di cuenta de que el problema no era encontrar coches.
El problema era tener suficiente informaciΓ³n para decidir si ese anuncio merecΓa mi tiempo.
AsΓ naciΓ³ HuntyCar.
No para sustituir los marketplaces, sino para ayudar a tomar una decisiΓ³n antes de escribir al vendedor.

Weβve received notice that the Department of Commerce has lifted export controls on Claude Fable 5 and Mythos 5.
We'll begin restoring access tomorrow, and will share an update soon.
Weβre grateful to our users for their patience, and to everyone who worked with us on redeploying the models.

The US government, citing national security authorities, has issued an export control directive to suspend all access to Fable 5 and Mythos 5 by any foreign national, whether inside or outside the United States, including foreign national Anthropic employees.
The net effect of this order is that we must abruptly disable Fable 5 and Mythos 5 for all our customers to ensure compliance.
Access to all other Claude models is not affected.
We apologize for this disruption to our customers. We believe this is a misunderstanding and are working to restore access as soon as possible.

El momento ha llegado, aunque dicen que han puesto guardarrailes estrictos, vamos a ver lo que tarda en salir una noticia asegurando que que se los han saltado π€
De momento para tareas restringidas va a derivar la conversaciΓ³n a Opus 4.8

New Anthropic research: Project Deal.
We created a marketplace for employees in our San Francisco office, with one big twist. We tasked Claude with buying, selling and negotiating on our colleaguesβ behalf.

Introducing Claude Opus 4.7, our most capable Opus model yet.
It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.
You can hand off your hardest work with less supervision.

Anyone has faced the βissueβ of small context windows on GitHub copilot when coding in VSCode?
I know it is manageable changing models between plan and implementation, but having @claudeai models with 1M token context but limited to ~160k is sometimes frustrating

Apologies, this was a docs clean up we rolled out thatβs caused some confusion.
Nothing is changing about how you can use the Agent SDK and MAX subscriptions!
