We've reset 5-hour and weekly rate limits for all users.
As a result of a US government directive, we are suspending access to Claude Fable 5 for all users. You can continue to use all other Claude models. Here’s what this means for you: Across Claude products, new sessions will run on your selected default model or Opus 4.8, and existing Fable 5 sessions will end with an error. On the Claude Platform, requests to Fable 5 will also return an error. Please update your integrations to other Claude models. We know this is a disruption to your workflows; we appreciate your patience and support.
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
In the AI era, I believe domain experts will become even more important. But expertise alone is not enough. Engineers who can turn that knowledge into production-ready systems and deliver it as something people can actually use will become increasingly valuable.
Today I ran a session for junior engineers on career survival strategies in the AI era. With the Claude Fable 5 announcement as added context, I shared thoughts on how engineering careers may evolve, where to focus, and what mindset we need to grow with AI.
Shipped kkdev92/vscode-ext-kit v0.3.1 — Disposable/storage/timing bug fixes, opt-in CSP & retry jitter & log throttle & telemetry redact, stricter wizard types, and a README that finally matches the actual API. github.com/kkdev92/vscode…
I also love hot springs and traveling, so maybe my backup plan is just reviewing food and onsens around Japan. lol
If engineering ever stops being a career, I have no clue what I’d do next. Since I love eating, maybe I could become a food reporter or something. lol
I wrote a short article about how engineers may become more “domain-hybrid” in the AI era. As coding gets cheaper, our value may shift toward understanding business workflows and creating outcomes. It’s in Japanese, so sorry if it’s hard to read! zenn.dev/kkdev92/articl…
Reworking the product concept. AI is moving so fast that I’m rebuilding the assumptions and the “right shape” from scratch. The old playbook doesn’t fit anymore—so I’m iterating, testing, and learning what works.
Thanks to github.com/microsoft/play…, my token usage for E2E tests has dropped significantly — it’s been a huge help. Both MCP and CLI have their strengths, but I’d love to see more tools offer solid CLI support as well.
I completely redesigned my portfolio’s top page using Claude Code (Opus 4.6). I’m really happy with how it turned out. Clarity matters.
It feels like I’m in the “Hyperbolic Time Chamber” from Dragon Ball — compressing years of growth into a short period of time. AI is amplifying my abilities many times over. This is the most fun I’ve ever had in my engineering career.
Thanks to the evolution of AI, I can finally reach the “itchy spots” that used to be out of reach — the things I wanted to build but had to give up on due to limited resources. This might be the most fun I’ve ever had in my engineering career.
For reference, I’ve published a Zenn article introducing vscode-ext-kit (currently in Japanese): zenn.dev/kkdev92/articl… An English version should be auto-generated soon.
