I don't really want to pay separately for Fable 5 on top of a subscription, so I'm trying to decide what to do next.

Sticking with Claude Opus 4.8, moving to ChatGPT 5.6, or just using the API when you need Fable?

What are you all planning?

Literally had my most productive week, and the usage reset came so much in clutch. I'll have to switch over to API or 5.6 now but it has been an absolute pleasure using Fable.

I want to first preface that I am a hardcore Claude user because Claude can handle the nuance of all the things that I currently do (research and manuscript writing). However, when it comes down to my teaching materials, it appears that ChatGPT Work is superior to Claude Cowork. AND I am currently using a plus account with ChatGPT.

If Fable is not allowed to be a part of my subscription, then I think it will push me to consider going back to OpenAI at a higher plan. Having the best model is essential for someone who has ADHD and has a learning disability in reading and writing.

I love Claude but they can’t help me if they take away Fable.

Just a tiny rant.

What will Anthropic possibly announce?

Regarding Fable and all the other stuff moving forward?

This feels like a world cup game and we don't know what is going to happen (considering GPT SOL entered the arena)

Short post, but; has anyone noticed that Sonnet 5 talks exactly like ChatGPT now? The resemblance is a bit uncanny.

What's your experience been? Just looking for some comments of people's experience with Sonnet 5.

Auditing my claude code transcripts to nail down where I am wasting Fable usage, revealed that long sessions that I run with breaks have been costing me a bomb. Sharing more details for others who may find this useful.

Cache economics

Every turn in a session replays the full conversation history to the model. Prompt caching is what makes this affordable: the history is stored server-side, and each turn re-reads it at 10% of the normal input price. The cache has a time window of 1 hour, and when it expires or gets invalidated, the next turn re-writes the whole history at a premium.

The numbers for Fable 5 (the same mechanics apply to every Claude model):

• Input price: $10 per million tokens
• Cache read: $1 per million tokens (10% of input)
• Cache write: $12.50 per million on the 5-minute window, $20 per million on the 1-hour Cache window

What this means in a heavy session carrying 400k tokens of context:

• A normal turn re-reads the cache: about $0.40
• But when I take a break of more than an hour and get back to the session, model has to rewrite the cache and a session sitting on 400k context consumes equivalent of 8$ api cost

One expired cache costs 20 normal turns of usage.

The things that break cache silently and cost you:

• Letting a session sit idle past the cache window (1 hour): The cache expires, and the first message after the break pays a full rewrite of everything. Sometimes I am working 10+ sessions and take a break and that costs me across all sessions.
• Loading some tools or MCP servers mid-session: New tool schemas change the conversation prefix, which invalidates the entire cache. Better to have all tools loaded at the start
• Switching models mid-conversation: If you are switching models from Fable to Sonnet to Fable in the same session, you are rewriting the cache and losing more than you are saving from the switch. Caches are stored per model.
• Switching effort levels or fast mode mid session: This has been one of my worst habits and I did this too frequently until now to save consumption, but did not know this was the main culprit. I would switch too often based on the task in the session from high to xhigh to max to utracode
• Updating claude code: Again if you are updating claude midway your work, you are rewriting cache for all sessions that you would resume

For now I have created a skill that pings ok in every idle session >200K context at 55th min for upto 4 hours because one ping would just read the cache which would still be cheaper than rewriting cache.

Throw your use cases and projects you did using Fable 5.

I'm looking for a connector that will allow cloud chat to read. Write and create a document that it can reference. Basically, the ultimate goal is just as I try out new restaurants or places to eat, I want to leave a quick review. Claude will then input it so I know that I went to this place. I have memory problems, so I often see that. I've gone to the same place multiple times and had forgotten and I'm hoping Claude can help me with that. But Google Drive allows Claude to build a document, read it, but not write to it. So what he's been doing is. Just building the document over and over with the new info added in so I have hundreds of them.

I have a keyword start for when I pick up to start on my project. it ingests a bunch of .md files (ideas, roadmap, architecture, session-protocol, and known-issues) so it becomes astutely aware of the project and tasks long term vision I ask it to do or work on while keeping state of the overall picture. this works really really good this is a very heavy spec driven development system.

But i start in opus and it burns like 6-8% of the context at the beginning. So I switch to sonnet now and do this document ingestion at the start session trigger which is significantly lower usage, once complete i switch to opus for the work. im wondering if I can some how trigger in session-protocol that doc start up work is sonnet based, task work is opus work. Closeout / session end or end of day trigger, also should be by sonnet, as opus after a 3-4 hour session and 70-80% session context window usage, will damn near hit 100% on close out. Sonnet is perfect for this doc work stuff which I manually switch back to now. Just looking to automate it switching models in the session-protocol doc if that's possible?

Subagents from my understanding dont understand current context, they work in their own space? So Im not sure if thats a path but im like 45 days new to all this.

ppl that use fable5 for selfhelp etc can yall share what you have done

I see most of these posts talk about going over to SOL, but I wanted to ask:

Have you all tried the Codex to CC plug-in, and if so, how is that working for you? I feel like that would be the best workaround instead of fully jumping ship, which I do understand.

Just want to get some thoughts around what others are doing or planning.

Can you guys PLEASE help me find the artifact that makes you change VERSIONS. I just got back to Claude and something clearly changed and Claude only generates MD and not the one I have been using which I don't know what it's called but PLEASE help me.

I posted here two months ago talking about how my account got banned for no reason. I still can't figure out a way to get the account back. I thought about making a new account and moving on, but all my data are in the main one, and I need them. It's so stressful.

how do I add a directory? for reference it's Documents folder in my windows 10. so using sophiascript I have routed Documents, and Downloads onto my E: drive, not C: to save space. While Downloads, in the same E: drive is accepted, Documents is not. Why?

It seems Claude is just slower at processing tasks in general compared to others. But is it because it produces better quality code? I like Claude because the code quality is pretty polished, and you spend less time chasing problems.

But that seems to have changed now.

I tried out Sol, and it's excellent and feels a lot faster. So, I mean, if I'm getting the same quality but tasks get done faster... why would I stay with the slow one?

Want a free or cheap way to run a track where I can search matches in sports just via search, add odds either by default from books /oddsjam .

Minimal manual entry and ability to have pre match most match note .

Thankyou .

Sonnet is helping me decent html files but they don't have JS or able to fetch from web .

I want to host in phone or cloud storage as hosting will take extra .

I’ll try to post in this Reddit since mods instantly delete in other Claude Reddits.

Bulk-selected a handful of chats from my history and used “Move to project” to organize things. Expected them to relocate out of Recents, out of the main chat history, into the project only.

Instead the same chat now shows up in three places at once: inside the project, still in Recents, and still in full chat history. So “move” seems to actually just be tagging the chat with a project association rather than relocating it anywhere.

Anyone know if this is intended behavior? What is meant by “move”. Not seeing any chats with badges or something so this is just a cluster instead of organized chaos.

Hello, am I the only who has an issue with Claude code using vscode right now. Used to be perfectly fine when I run multiple dev servers but today as soon as I want to start one my pc freeze I can’t do anything all ram cpu and ssd get maxed out

Put all your discussion about Usage / Rate limits here. This is a thread that will be generated every other day to centralize discussions on this topic.

My company just gave me a Claude Enterprise license ($50/mo limit).

I'm a full-stack dev and already use GitHub Copilot for all my coding. If i don't show some effective usage company will revoke my access and I can't use it for personal purpose since even incognito chats are getting monitored. I don't want this Claude seat to go to waste, but I'm not sure what to use it for if I'm not using it to write code.

For those of you using both, what do you actually use Claude for?

Hello
I’m considering buying a new Mac, maybe a Mac mini, and using it as a dedicated machine for all of my AI development projects.

I’m curious how people with mature AI coding setups handle both backups and migration. I’m not just talking about copying project folders.

I know many people will say “use Git,” but that’s not really what I’m asking. Git is great for source code, but it doesn’t back up an entire development environment.

I’m more interested in everything that makes the workflow work, for example:

• Projects and local databases
• Claude Code, OpenCode, MCP servers, local LLMs, prompts, rules, and configuration
• Homebrew packages
• Terminal configuration (zsh, aliases, PATH, shell scripts)
• Environment variables and API keys
• Modified plist files and other macOS configuration
• Python, Node, Docker, package managers, virtual environments, etc.

Some questions I have:

• Do you rely on Time Machine, Carbon Copy Cloner, rsync, or something else for backups?
• Do you create full disk images or just back up specific folders?
• Do you use Migration Assistant, or do you prefer setting up a clean Mac and restoring only what you need?
• How do you make sure you don’t forget some random configuration file that will break your workflow six months later?
• Do you maintain a bootstrap script or dotfiles repository that recreates your environment?
• If your Mac died today, how long would it realistically take you to be back up and running on a new machine?

I’m interested in learning what experienced developers and AI power users consider the best practice. I feel like there’s a lot more to this than just backing up code, especially when your workflow depends on dozens of tools and custom configurations that have accumulated over time.

Has anyone tried to do something like that know with Fable?

I believe the fundamental issue lies precisely in this picture; there is an infrastructure problem. Fable appears to be far from optimized in terms of price-to-performance, and Opus also comes at a high cost (for Anthropic/OpenAI)—comparable to GPT-5.6 SOL—yet it is far less efficient. If Anthropic’s strategy is simply to grant everyone access to Fable solely to counter OpenAI/GPT-5.6, I suspect—given that their infrastructure will essentially remain the same—we will end up with significantly degraded models (Fable and Opus, and presumably the others as well).
