Anthropic engineer: "Fable is one of those models you’ll just remember - like Sonnet 3.5, Opus 4, Opus 4.5. We just removed 80% of Claude Code’s system prompt. A new class of models wants a smaller prompt." in 20-minute session, an Anthropic core engineer reveals the capabilities of Fable....

Did I just unlock claude-fable-5-lite? 😂 Since Fable 5 got pulled (US export control order, Anthropic is contesting it), I wanted to see how much of its character lives in the system prompt vs. the model itself. I ran the leaked Fable 5 prompt on Opus 4.8 head-to-head against stock 4.8.

Creator of Claude Code: “Fable 5 is writing 100% of my code now. It’s at least 3x more powerful than Opus.” Every problem I gave to Fable, it one-shotted. I’m running out of coding problems for it. in 40-minute talk Boris explain how to unlock 100% potential of Claude new models Fable 5 + loops + dynamic workflows + routines- that’s the secret Worth more then 500$ vibe-coding course

Anthropic engineer: "Most people will use Sonnet 5 and Fable 5 wrong. You can set them up right in one afternoon and stop overpaying every single day." In 29 minutes, he breaks down every Claude model, and why running them all the same way is a mistake. Watch the session, then save the config below 👇

Anthropic CEO: “At Anthropic, we essentially have Claude designing the next version of Claude itself.” Meanwhile, Anthropic says every new model is given code that trains a small AI model and asked to make it faster. Claude Opus 4 achieved a 3x speedup. Mythos Preview reached 52x. Recursive self-improvement is starting to look real The models are helping build what comes next.

This is the best way to use Claude Fable in Claude Code without immediately hitting your limits. 1. Model set to Fable 5 2. Reasoning on Max 3. Instruct Claude to run a dynamic workflow where: 3a. Fable is the orchestrator 3b. Opus does the reasoning heavy phases Fable is so overpowered that you don't need its intelligence for every step. Let it orchestrate Opus or even Sonnet.

Most people are using Fable 5 wrong & overpaying every single day. Anthropic's Head of Labs just showed how to use Fable 5 the right way. He shared the exact workflow they use internally: -Run parallel Claude sessions. -Fable only for planning. -Sonnet for quick questions. -Effort levels for simple work. -Verification loops that catch mistakes before they cost tokens. After this you will run Fable 5 like an Anthropic engineer. Bookmark this or keep burning your tokens.

GPT 5.5 just buried opus 4.7 I had it build a pokemon style battle app. 1 prompt. the opus game crashes 90% of the time and Ui is absolute garbage. GPT 5.5 one shotted a masterpiece. Time to cancel anthropic sub?

Anthropic engineer: "Over 90% of Anthropic engineers use a self-improving agentic loop for coding. The key is to close the loop: give the agent a way to verify and improve its own work" In this 12-minute talk, an Anthropic engineer explains how to build an agent that continuously improves itself. Claude + routines + loops + CLAUDE.md - that's the foundation. Skip Netflix tonight. Save this post!

Wow Claude Fable 5 is insane!! It just recreated the 2011 game of the year (and probably one of the best games ever created) The Elder Scrolls V: Skyrim in ONE prompt. Prompt: make skyrim It over for game studios now.

Are AI agents shape rotators? In this new benchmark, we let the models play campaign puzzles in Opus Magnum, a puzzle game by Zachtronics. Ironically, Claude Opus 4.8 performed poorly, being beaten by GPT-5.5, Gemini 3.5 Flash, and GLM 5.2. Claude Fable 5 crushed them all.
