We know this has been frustrating, and we want to give you more certainty about what your plan includes. We are making access standard at 50% usage for the plans that use Fable most intensively.

Thank you for your patience over the past several weeks. We're continuing to invest in new capacity and will keep everyone updated as we do.

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.

And transitively might also have reset other rate limits out there. Let's see. You're welcome if so.

Oops... I did it again.

Enjoy reset usage limits for all paid users for Codex and ChatGPT Work. Super grateful for an incredible team who is iterating at lightspeed and keeping the infra up as we scale faster than ever.

Enjoy the weekend! https://t.co/WIuS07doKA https://t.co/3NwNqHG7TV

building prototypes of mockups, schemas, data models, proof of concepts, etc. is the best way to avoid spending tons of tokens before realizing you don't want the output https://t.co/BjYeXC7zfk

This post is key. The cheaper AI gets, the more opportunity there is for the entire ecosystem - especially including end-customers - to benefit.

Everything is bottlenecked by being able to successfully and cost effectively deploy AI in real workloads. Any time we can lower the cost of AI, the total usage goes up. When that happens, the value accrues to all layers of the stack, as noted.

The only modification is I think as AI gets more efficient, demand even for the frontier closed models can go up too. You often need the strongest model possible for the orchestration of a task, then you can farm out work to cheaper or more tuned models for the bulk of tokens.

This efficiency gain can ironically lead to even more frontier spend in the process because you can cost effectively deploy AI against more tasks. The thing at most risk is margins, which is fair, and in general it seems that intelligence eventually should converge with the margins of the infrastructure stack.

Anyway, super fun times to see competition play out to drive down the cost of AI.

It's both amazing and painful to watch codex use browser + computer use to open Chrome, go to my PR, tap on comment and wrangle with the macOS picker - all TO UPLOAD AN IMAGE. GitHub has no API doesn't stop anyone.

I let my codex run in VMs so they don't steal app focus. https://t.co/Dd5KzNs6E5

Are we still talking loops or did we shift to graphs yet?

ya'all made me go crazy with codexbar icon customization issues, so I built an editor.

Why do you think kimi hurts Google?

Many enterprises won’t consume Kimi directly. They’ll get it through Google Cloud because they still need enterprise guarantees - security, data residency, compliance and most importantly, chips.

Money out one pocket into the other.

The reason enterprises struggle to go beyond basic chat bots is the talent gap to build harnesses and evals.

1. Evals: do you clearly understand your use cases and can you replicate that in the form of offline and online evals. Do the evals express your ambition and do they push the jagged frontier of the models? Do they help you pick the right models on the quality-cost-latency curve?

2. Harness: do you have a system that manages routing, multiagency orchestration, context management, tool calling, memory that is independent of the models?

3. Talent: do you have the talent to build this all out on the frontier?
This is the scarcest piece.

Codex browser use has finally been defeated. https://t.co/qGAIvxtjnJ

Legendary episode dropping this weekend featuring the one and only @trq212, who showed me his AI video workflows and much more.

📌 Subscribe to get it on Sunday: https://t.co/744uInp9aE https://t.co/ZTh2IpXRnM

The reason I want this btw is spending an entire day staring at screens trying to manage agents fries my brain.

Much better to be walking around outside talking to the agents "on the phone" giving them work to do and having them update me on status via voice.

Can't wait for the first lab to ship this.

Great video https://t.co/tGU8LfdzFQ

Tip for building in public:

If making content feels like extra work, show the work already happening inside your product. A tiny screen recording, the first version, or the user behavior that changed your design. The reasoning matters more than production value.

Just a few years ago, many people were uncomfortable with recording meetings

Now it’s just assumed that all business meetings are recorded (not for humans, but for agents)

Technology really changes culture

still true https://t.co/2eYqwze1Ae

alpha only gone when we all stop asking these level of questions and start discussion about on-policy autoaeo (does claude optimizing your aeo disproportionately work on claude?) vs generalizable aeo

https://t.co/GrymTTqz6O

btw if you havent set your {codex | claude | gemini | devin} automations to autoresearch how to improve your seo/aeo every week you are really truly missing out on free, should-be-commoditizing-but-weirdly-untapped alpha
