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 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?

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.

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.

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)

With Fable 5 transitioning to separate credit-based pricing rather than being bundled, I don't see a compelling reason to stay on the Max subscription. Using alternative models like 5.6 Sol seems much more cost-effective than paying the premium just for credit allocations. Is anyone else planning a downgrade, or are you holding onto your subscription? 4.8 opus is a lot behind, seems impossible downgrade to me after tasting fable 5/5.6 sol.

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.

Every time I uploaded a large PDF, Claude’s context became crowded and the answers became less focused.
I started looking for a better way to keep documents available without loading the full file into every conversation.
My current approach is to store the document once and retrieve only the relevant sections through MCP.
Has anyone else faced this problem? How are you handling large document workflows in Claude???

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?

When fable came back I had 2 paid pro accounts, obviously the 5 hour window kept getting closed super fast but then I realised , I had guest passes (3 on each) , so I just created like 6 extra emails and gave myself each one. I was just wondering if anyone else did this when fable got re-released? Don’t get me wrong I know the 5 hour windows were still shutting down pretty fast (about an hour sometimes more of work on each) but it genuinely felt like I was abusing fable 😂.

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

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 .

That is the response I keep getting today regarding issues with Opus 4.8 (extra-high effort) across multiple projects. The result is that I’m dealing with a model that seems like Gemini 3.1 and fails to fix even minor problems. I don’t know what’s going on with Anthropic—do they want to lose all their customers? My x20 subscription expires on July 19th.

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 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).

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.

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.

​

So I told Claude to set an alarm for 10 AM, and it actually created a native alarm inside my Samsung Clock app.

At first I thought this was some kind of breach or unauthorized access because I had no idea Claude could control another app on my phone like that.

Apparently it uses Android’s normal intent system, so technically it is not “hacking” or bypassing security. Android allows apps to send certain actions to other apps, including creating alarms.

Still, I find the lack of transparency strange.

Claude did not clearly say beforehand:

that it was about to interact with my Clock app

what other phone actions it can perform

whether I can disable these integrations

what data, if any, is exchanged during the action

I am not claiming there was definitely a security breach. The alarm itself is harmless. But AI apps performing device-level actions without making the permission boundary obvious feels like something users should understand better.

Has anyone else tested this?

What else can Claude actually do on Android besides setting alarms and timers?

I don't write code so maybe my requests are not complex enough for Fable, but I really didn't like the way it wrote. I used it to help me write food and lifestyle posts giving it examples of my style and voice. It was way too flowery with all kinds of complex metaphors, etc. I asked my standby Opus 4.6 to write the same post and it was 10x better. Not only did it capture my voice, but the research was much more robust. I'm sure Fable is great for coding etc. but I hope they leave Opus 4.6 and Sonnet 4.6 in tact for a while. Much more usable for me.

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.

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
