- Introducing Grok 4.6
Grok 4.6 advances long-running agent capabilities and visual/interactive work, matching GPT-5.6 Sol on the AA Intelligence Index and launching in Cursor and Grok Build with 2x usage for the first week.
- August 2026 Ramp AI Index: Cracks in the AI thesis
Business adoption of premium AI models like Anthropic's Fable 5 is slowing despite superior performance, as cost sensitivity grows and open source alternatives gain traction among advanced spenders.
- Everything hackable will get hacked - Vercel
Vercel argues that open-weight models like Kimi K3 already enable offensive security research, but defenders can use stronger frontier models today to proactively find vulnerabilities via tools like deepsec before the advantage erodes.
- Agent swarms and the new model economics
Cursor’s new agent swarm design builds SQLite in Rust with far higher success and far lower code size and cost than its earlier swarm.
- U.S. Bars Foreigners From Using Anthropic’s Most Advanced A.I. Models
The U.S. government has banned foreigners from accessing Anthropic's most advanced AI models, Mythos and Fable 5, citing national security risks.
- If Claude Fable stops helping you, you'll never know — Jonathon Ready
Anthropic's policy to silently degrade Claude for frontier AI tasks erodes developer trust, though the company later walked it back after outcry.
Takes
someone at beehiiv probably paid $10,000+ for that launch video polished, agency-grade, beautiful and the top reply thought they shipped a Microsoft integration.. because they named their agent "Copilot" .. all that work, and the launch still failed the only test that matters: 👉 3 seconds, one clear promise for context: I make launch videos with Revid MCP + Fable 5 one prompt -> 5 hook variants -> post the winner less than $100

Maybe Intelligence Ain't All That
@CliffordSosin
few weeks ago, Fable 5 was so advanced it needed the gov and had to be taken offline. today, we have access to arguably better models for $20/month. took what? six weeks?

Respect to Fable 5, but this is a different league.

Fable 5 + Goose Ads is insane – literally a full ad-creative team right in Claude Code. 1. Install the skill: npx gooseworks install --all npx gooseworks login 2. Ask Claude Fable to make ads for your brand. /goose-ads create ads for my brand <your-website>. Fable 5 pulls the ads already winning in your space and rebuilds them on-brand – your product, your palette, your copy – a whole batch, ready to test. It can ship a month of creative testing in a single prompt. This is also possible with Opus and Sonnet, but Fable's brand research is next level. Link below.

Sonnet 5 is here. It's worse than Opus 4.8 on nearly every benchmark... Does that mean it's useless? Absolutely not. Use it with Claude Code Dynamic Workflows! 1. /model set to Sonnet 5 2. /effort set to Ultracode 3. Any complex task will kick off a dynamic workflow This will only become more powerful when Fable is back. You'll use Fable 5 as the superintelligent advisor and Sonnet 5 as the fast and efficient implementer.

Rough estimate on $ productivity lost by Fable 5 ban: $12M per hour Frontier AI-coding daily actives, mid-2026: 5M devs Fully-loaded cost: $90/hr Work routed to Fable in 48 hours: 17.8% Fable is on average ~15% more productive Effective throughput loss per dev = 17.8% × 15% ≈ 2.7% of output 2.7% × $90/hr = ~$2.40/dev/hr × 5M devs = $12M per working hour
@garrytan
I gave Fable 5 a blank folder and made some skills/claude.md and gave it my robinhood agentic trading account with $250 in it let's see what it can do
@mweinbach
Fable 5 is now available in Claude Code and Cowork Fable is the best model I have used for coding, by a wide margin. It is a big step up, enabling less prompts and steers, more efficient token use, better code quality, better tool use, more intelligent self-verification, longer running sessions, and higher trust & autonomy. Happy coding!
