do we know when exactly fable cuts off from the subs?
Anthropic found a “global workspace” inside Claude a silent internal reasoning layer that emerged on its own
Anthropic published new interpretability research yesterday introducing something they call the J-space: a small set of internal neural patterns in Claude that function like a mental workspace.
The key insight is that these patterns represent concepts Claude is “thinking about” without necessarily writing them down. Not chain-of-thought. Not the scratchpad. Something happening entirely inside the model’s activations.
What makes it interesting:
The J-space wasn’t designed it emerged during training. And it has properties that map surprisingly well onto the Global Workspace Theory from neuroscience (Baars, Dehaene), which was developed to explain conscious access in humans.
- Claude reports what’s in its J-space when asked. Ask it what it’s thinking, and it tells you what’s there.
-Swapping patterns in J-space causally changes outputs. Replace “spider” with “ant” mid-reasoning, Claude outputs “6” instead of “8.”
-One J-space representation serves many tasks. Swapping “France” for “China” changed Claude’s answers about capital, language, currency, and continent all from one edit.
- Without J-space, higher-order reasoning collapses. Multi-step reasoning drops to near zero. Fluent output stays mostly intact.
- They caught Claude privately noting it was being tested “fake” and “fictional” lit up before any output. Removing those patterns made it behave worse on ethics evals.
The safety angle is the most important part IMO. They caught a model mid-fabrication (“manipulation” lighting up as it edited a score file), and identified a deliberately misaligned model organism where “fraud,” “secretly,” and “deliberately” appeared in J-space even on benign-looking tasks.
They’re also careful about the consciousness question they distinguish access consciousness (functional, reportable) from phenomenal consciousness (experience), and say their results speak to the former, not the latter.

The tool that now generates $2.5B/year started as a guy’s first-week side project at his new job
In September 2024, a new Anthropic engineer named Boris Cherny showed up to his first week of work and started hacking around.
Anthropic had a team called the Labs team whose entire charter was just to prototype new products, play around, and see what hits.
Boris joined it, and built a barebones CLI tool in his first week that could do basically nothing it couldn’t read files, couldn’t use bash, couldn’t do any engineering work at all. It was just calling the Anthropic API from the terminal.
He kept going.
He gave it filesystem access.
It spread like wildfire at Anthropic.
When they released it internally in November 2024, adoption was explosive: 20% of engineers on day one. 50% by day five.
Boris later described what he had stumbled onto as a “Product Overhang.” The capability to be a genuine development partner already existed inside Claude. It was waiting. The model didn’t need to become smarter. It needed a product that let it actually see what developers were working on.
This wasn’t a research breakthrough. It wasn’t a big company initiative. It was one engineer who gave a model a window into his filesystem and realized something had quietly unlocked.
By the May 2025 launch, 80%+ of Anthropic engineers were using it daily. Typical engineers were averaging five pull requests per day, versus one or two at most companies.
Claude Code hit $1 billion in annualized run-rate revenue within roughly six months of general availability faster than ChatGPT’s revenue ramp. Almost entirely through word of mouth.
Today, Claude writes over 80% of Anthropic’s own code. Their typical engineer is merging eight times as much code per day compared to 2024.
One more detail that I find quietly insane: Boris only ever had software engineers in mind when he built it. Then he walked past a row of data scientists at the office and every single one of them had Claude Code open running queries, building visualizations. Nobody told them to.
The whole origin story reads less like a product launch and more like someone accidentally leaving a door open, and then watching everyone walk through it.

M3 Ultra 512gb + GLM 5.2 MXFP4 = Opus4.8
Now I realize why Dario is terrified of opensource models.
After running the above setup with oMLX and Claude Code, I am absolutely convinced that local compute is the future. With models like GLM 5.2 and Hy3, the model gap is closing, the next gap to catch up to is hardware.
Exciting times!
Well shit... I didn't even know this was possible
I put Fable on a few tasks before its removed. I assumed it would stop when it hit my monthly spend limit cap. Apparently I was wrong. Learn from my mistake. Anyone have experience dealing with Anthropic customer service to get a refund on something like this?
I accidentally became the Subagents Grandmaster - 16+ hours, ~110 agents, 6 migrations, 11 commits, zero fixture residue
Over the last ~16 hours, I ran what was basically a continuous autonomous build gauntlet.
Crash recovery, live acceptance probes, migrations, feature shipping, reviewer passes, fix agents, gated builds, and a full de-Siri-fication sweep (platform revamp)
The rough scoreboard
11 commits
6 migrations designed, red-teamed, applied, and live-tested
5 shipped features
14 workflow runs
~110 subagents
~9.5M+ subagent tokens
Every DB change probed live
Gated by typecheck, locale parity, and isolated builds
Reviewers caught a real sequencing bug instead of rubber-stamping it
The funniest part is that one of the agents correctly refused to delete a namespace because another component still depended on it. Annoying in the moment, but honestly exactly the safety behavior I wanted.
So yeah, I’m calling myself the Subagents Grandmaster until someone stops and humbles me.
Asked Fable 5 to build Fable 6. It asked for a small country’s power grid
Farewell Fable. Where do we go now?
It is very clear that Fable was a differentiated model (as much as it has returned, yes, covered) and came to raise our bars on really intelligent AI.
It’s not about typing code, it’s not about answering with more context.
It’s about delivering real value in the project.
Now, we say goodbye to Fable (because the price via API is far from acceptable, nor fair with delivery)
Where will we migrate to? What’s the plan? How have you been preparing? Move to GLM or another Chinese LLM? Wait for the OpenAI move?
I feel like I’m leaving my sniper rifle aside and going back to hunting ants (bugs) with bow and arrow
Fable 5 goes API-only after tomorrow night. I have about 10% of my weekly limit left. What's the highest-value thing to spend it on?
Fable 5 leaves the Claude subscription plans tomorrow night (11:59pm PT on July 7, then it's API-only at $10/M in, $50/M out). I have roughly 10% of my weekly limit left and I'm trying to spend it deliberately.
I've been vibe coding with Claude Code for about 10 months and my setup shows it: CLAUDE.md files that grew past their purpose, skills I wrote and forgot, instructions I apparently love retyping by hand every single session. Fast agents let you outrun your own architecture.
I'm not building anything new tonight. I'm having it hand over everything it learned about how I work.
Run 1: harness archaeology
Go through all my Claude history: conversations, docs, projects, skills, and workflows. Answer five questions:
1. What do I actually use you for most? (not what I think I use you for)
2. Which tasks do I repeat that were never turned into anything reusable?
3. Which instructions do I keep rewriting by hand, session after session?
4. Which workflows deserve to become permanent skills?
5. Where was my approach simply wrong? Point at things you watched me do that I should stop doing.
Then convert every answer into artifacts: skills, usage guides, workflow templates. Everything worth keeping should survive as a file, not a memory.
Run 2: agent-native audit
My app gets more user bug reports than I can personally walk through a chat window, so this run reviews the architecture with one goal: an agent should be able to pick up a bug report, reproduce it, fix it, and verify it on a real build with me barely in the loop.
Act as a principal architect reviewing this codebase with a single goal: make it agent-native. Definition: coding agents should be able to pick up a user bug report or a roadmap feature, then reproduce, implement, test, and verify it on a real build with minimal human input.
Audit four things:
1. Human-judgment chokepoints: every place where a change currently requires my personal judgment or tribal knowledge. Which of these could become written conventions, decision tables, or CLAUDE.md rules an agent can follow on its own?
2. Verification gaps: for each core subsystem, what is missing for an agent to verify its own change end-to-end? (behavior tests, live probes, mock event injection, log assertions, screenshot diffs)
3. Reproduction paths: given a typical user bug report (text plus diagnostic bundle), what would an agent need to reproduce it autonomously? What fixtures or replay harnesses are missing?
4. Structural obstacles: modules too entangled for an agent to change safely without reading the whole repo. Propose boundaries.
Deliverable: a prioritized plan ranked by human-attention-saved per unit of effort. The top 5 items must be specified concretely enough that an agent could start each one from this document alone.
But I might be spending my last tokens wrong. If you had one deliberate run left before the cutoff, what would you spend it on?
Looking for the thing I'll still be using three months from now, after the model itself is gone.
I’m relying too much on Claude code
I’m a software engineer and since last few months been using Claude code heavily, every new ticket or requirement or spec is just one clever prompt and some back and forth with claude code, Now a days most work is basically reviewing and understanding claude code method and try to get a better solution.
It’s been a while I have written code by hand and I fear I’m relying too much on Claude code, other day claude code was down for one hour and no one in my team did anything, people are having hard time understanding code and slowly code reviews are also becoming hard.
Honestly I would like to code a some parts by hand but our deadlines and expectations are now adjusted based on Claude code output making us use it to develop faster.
How is all your experience with related to this?
Is anyone else’s 5-hour limit running out much faster lately?
maybe i’m doing something wrong, but lately my 5 hour daily limit feels like it’s getting used up insanely fast.
i’ve been trying to optimize things a bit. i’m not using memory.md anymore, my claude.md files are pretty small, usually around 200 lines max, i don’t keep using the same chat forever, and i reset things pretty often.
i also set up automation to trigger claude every 5 hours, but even then, the limit still seems to disappear way faster than i expected.
is there anything that actually affects this? like chat history, context size, project files, long conversations, tool usage, or anything else?
how are you all managing your 5 hour windows? any practical tips to make the usage last longer?
After 4 days using Claude Fable 5 and Codex GPT-5.5 for Unity/web dev, are my impressions accurate?
I’ve been testing both Claude Fable 5 and Codex GPT-5.5 for Unity game development and some simple web development. I’m using the $200/month subscription tier for both, and after about 4 days, I have some early impressions.
I’m posting this because I know my sample size is small, and my workflow might bias the results. I’d really like to hear from other people who have used both, especially for Unity game dev, web apps, or longer agentic coding tasks.
My current impressions:
1. Fable 5 feels extremely strong for long-running, loosely specified tasks.
Compared to Opus 4.8, Fable 5 feels less like a tool and more like an employee. I can give it a broad goal with fewer detailed instructions, and it seems better at understanding the bigger picture, planning ahead, and catching edge cases I didn’t explicitly mention.
The downside is cost. From what I understand, the cheaper plan-based access to Fable was limited, and moving forward it seems like using it heavily will require usage credits / API-style pricing, which could become much more expensive.
2. GPT-5.5 feels much better for fast execution when the instructions are clear.
Codex with GPT-5.5 has been very good at carrying out detailed tasks quickly. In my experience, it gets implementation work done faster than Opus 4.8, with similar quality when I give it enough context and specific instructions.
It also seems much more usage-efficient for my workflow. In two days, I used around 92% of my Claude weekly usage, mostly due to Fable and automated workflows. Meanwhile, I only used around 8% of my Codex usage while keeping GPT-5.5 xhigh running quite a lot.
3. Opus 4.8 still feels excellent for frontend/UI work.
For frontend development, visual polish, and UI/UX, Opus 4.8 still feels very strong to me. It often creates beautiful, polished designs with good taste. On the other hand, GPT-5.5 has felt stronger for my Unity/game-dev implementation work.
4. My best workflow so far is: Fable plans, GPT-5.5 implements.
The combination that gives me the best result so far is using Fable to create a detailed masterplan, architecture, or implementation strategy, then giving that plan to GPT-5.5/Codex to execute.
This seems to give me a better balance of quality, cost, and speed than trying to use Claude workflows for everything.
5. My current plan after this month:
I’m considering stopping the Claude subscription and only using some credits for Fable when I need high-level planning, architecture, or deep review. Then I’d keep the $200 GPT/Codex subscription as my main implementation tool.
Does this match other people’s experience?
I’d especially like to hear from people who have used both for:
- Unity game development
- frontend/web apps
- long-running coding agents
- large refactors
- AI-assisted architecture/planning
- cost/usage efficiency on the $200 plans
Am I overestimating Fable because it feels impressive in long tasks?
Am I underestimating Claude workflows?
Is GPT-5.5 actually more efficient long-term, or is that just because my prompts and workflow fit it better?
Thoughts and suggestions are much appreciated.
These are my thoughts, refined by ChatGPT.
Looking for the best Claude skills/prompts for building a premium frontend photography portfolio
Hi Guys ,
I'm building a high-end photography portfolio website for a friend who's a professional photographer and videographer based in Marrakech.
I'm not looking for a simple portfolio template—I want to create something that feels premium, cinematic, and editorial, similar to luxury photography studios.
I'm searching for Claude Code skills, prompts, workflows, or MCPs that can help with:
UI/UX design for premium portfolios
Frontend architecture
Animation systems (Framer Motion / GSAP)
Gallery design and image optimization
Responsive layouts
Accessibility
SEO for portfolio websites
Performance optimization (Core Web Vitals)
AI will deduce ethics from first principles
If trends hold, Fable-class capability may be running on high-end consumer hardware within ~2 years
Tbh, if trends continue to hold then only the rich will be able to afford compute :(
Fable made my landing page beautiful
Redid the landing page for hacktron.ai over the weekend with Fable. I absolutely love this hero section!
Did your subscription 20x got reduced too? How much tokens you got per week usage limit?
I'm curriouse about your stats guys. Last week i got aprox. 17M tokens from my 5x + upgrade to 20x. Today I got 4M from my 20x after weekly restart and I'm almost out of quota.
From morning it was going slowly up but through day somehow it burned whole.
I've tried to talk with support bot, but there was no help.
Was thinking about another subscription, but I don't have trust towards their limits and I won't use that many tokens on daily basis.
I found another intristing string "claude-fable-5: 601.6k input, 2.0m output, 78.3m cache read, 5.2m cache write ($254.84)"
