Anthropic Shipped Two New Models. They’re the Same Model.

by

TL;DR: Anthropic launched Claude Fable 5 For more context, see: how GPT-5.5 compares on AWS Bedrock. (general availability) and Claude Mythos 5 (restricted, cyber defenders only) on June 9, 2026. Same underlying model. Different safety posture. $10/M input tokens and $50/M output — less than half the price of Mythos Preview (Related: my Claude Opus 4.8 playbook for production prompts). Part 1 of 2: specs and use cases. Part 2 will be the review after I have run something real on it.

I opened Anthropic’s newsroom on Tuesday and saw two new flagship models. Then I read the second paragraph and realized they were the same model.

That is the structural fact nobody is writing about. The release notes, the benchmark table, the customer quotes — all of that is downstream of one decision Anthropic made: a single frontier model, packaged twice. Once for everyone. Once for the people with a clear reason to be dangerous.

The packaging is the product. Let me walk you through what’s actually shipping, what the safeguards mean in practice, and what I want to test once the access thaws.

Design Thinking Is 80% Theater. Here’s the 20% That Works.

Last quarter I ran a design thinking sprint on an AI agent project. Three weeks in, the only thing I’d produced was a wall of Post-it notes, two empathy maps, and a definition statement nobody on the engineering team could repeat. The agent itself had not moved one line of code forward (Related: when human oversight saved my AI projects).

Then I threw out 80% of the framework and kept the 20% that actually shipped the project.

Design thinking, stripped of consultant-speak, is a debugging loop for the gap between “what we think the user needs” and “what the user actually needs.” Most of what gets taught in corporate workshops is theater. The 20% that matters is something engineers have been doing for decades under a different name. They called it “writing tests against user behavior” or “asking the customer before shipping.”

This post is the 20%.

I Replaced 3 Paid Monitoring Tools With a Homelab at $0/Month

by
Susiloharjo

I was paying $25/month across three monitoring services for the same thing: knowing when my homelab services go down. Better Uptime ($5), UptimeRobot ($8), and Grafana Cloud ($12 for metrics retention). Last month I replaced all three with a single Docker Compose stack (Related: how I built another $0 homelab solution) running on the same … Read more

I’ve tried Habitica, Streaks, Loop Habit Tracker, and three other apps. Every single one worked for about 3 weeks. Simple productivity tools often outperform complex solutions Then I’d miss a day, feel guilty, and never open the app again. So I built something dumber. the post that changed how I write about tech It’s been … Read more
