🍭 The Fable Ban Just Built A Rival 🌐

Good morning. The US banned Fable 5 on Friday evening. By Saturday, a Chinese lab had open-sourced the replacement under MIT.

Some ironies don't need a punchline.

Let’s dive in 👇

🍭 What’s Cookin’:

• Zhipu AI shipped a Fable 5 replacement before the ban ink dried

• ChatGPT lost its market majority for the first time

• Anthropic sent engineers to Washington to negotiate Fable 5 back

Power Shift
🧠 The Export Ban Backfired In 48 Hours

The Bite:

Chinese AI lab Zhipu AI released GLM-5.2 on June 13, one day after the US Commerce Department ordered Anthropic to disable Fable 5 and Mythos 5 worldwide.

The model is a 744 billion parameter, Mixture of Experts architecture, with a one million token context window.

Zhipu is releasing GLM-5.2 under the MIT license with no regional usage restrictions.

Pricing through Zhipu's GLM Coding Plan is roughly one tenth the cost of Anthropic's Claude Code and Claude Max tiers.

Zhipu's Hong Kong listed stock surged 48% intraday on the announcement, closing up 32.8%.

Snacks:

• GLM-5.2 uses 744B parameters in a Mixture of Experts design with 40B active per token

• Scored 42.8 on BridgeBench Reasoning, beating Fable 5 on that specific benchmark

• Runs at approximately 300 tokens per second

• Zhipu's stock is up 820% since its January IPO in Hong Kong

• Founder Jietang Tang cited the Fable 5 ban directly in the launch announcement

• Open weights ship under MIT this week, API went live Monday

Why it Bites:

The export control logic assumes frontier AI has no substitutes.
That assumption broke in 48 hours.

But Zhipu didn't release GLM-5.2 into a vacuum.

It released it into a market where everyone who relied on US-based companies was suddenly threatened to be locked out and looking for alternatives.

And the MIT license means the weights can be downloaded, redistributed, and deployed anywhere. No API key to revoke. No directive to comply with.

The total opposite of the western companies.

A year ago, the capability gap between US and Chinese frontier models was wide enough that export controls carried real strategic weight. Today, GLM-5.2 matches Opus 4.8 on several benchmarks at a tenth the cost.

The moat isn't gone, but it's ankle deep.

The real damage isn't the model, though. It's the migration.
Creators who switch this week probably won't switch back when Fable 5 returns.
They'll have built pipelines, written evals, shipped products.

The Commerce Department didn't hand Zhipu a news cycle.

It handed them an onboarding event.

CodeRabbit
🔬 Review the actual change, not the file list.

AI writes more code than ever.
Reviewing it shouldn’t mean scrolling forty files in alphabetical order.

CodeRabbit Review reorganizes any pull request from a flat file list into a structured, layer-by-layer walkthrough — the logical reading order of the change, not the order your platform happens to sort it. Every range gets its own plain-language summary, with sequence diagrams, state machines, and ERDs generated inline wherever a visual earns its place.

Cohorts group related files and chunks so you review one idea at a time. Layers order them so foundational changes — data shapes, contracts — come before the code that depends on them. Code Peek lets you click any variable, function, class or type to see its definition and usages without leaving the tab, while Semantic Diff view cuts past formatting noise to show what actually changed.

Open it straight from the Review Change Stack button in the PR Walkthrough.
Navigate cohorts and layers from the keyboard, comment against exact line ranges and submit native reviews, comments and approvals post back to GitHub or GitLab right where your team expects them.

In the early access, available for free to everyone.
