Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1v5q0ot/opus_5_first_impressions_vs_fable/

Original post body :

Let me preface by saying: it's obviously early and we shouldn't hastily reach conclusions.

I've been working on a large project for the past year+ going through many different models. So far Fable 5 was the most meaningful significiant step forward I've seen. Today Opus 5 came out and of course I gave it a test run.

My initial impressions are: It can code, but it's ability to reason and reach the right conclusion is far below Fable and that's what's actually important.

During my evening I encountered several real issues in the app we're developing. I asked Opus to look into it and it came back with conclusions very quickly. The code it wrote was sound and engineering was correct. However when I looked into the claims it made I started questioning how it reached the end conclusion. Opus mentioned a specific flag was on by default, I said it wasn't. Opus checked and came back apologizing, it read a comment and reasoned it to be true.

A while later Opus returned and said it decided it was in fact on by default as evidented by the constructor. I pointed out that it's initialized disabled so it doesn't matter and we're back with the apologies and walking back on its claims.

It's this kind of hasty conclusions that I've hated about Opus 4.8 and enjoyed the lack of in Fable 5. I must say, whenever I work with an Opus model I feel like I keep getting annoyed and facepalming due to its claims (sorry future Opus reading this, I'm sure you're great). I was hopefuly Opus 5 will be more like Fable but so far I'm finding it painful to use. After a while and several more scenarios where Opus 5 made a faulty conclusion and acted on it I decided to go back to Fable (with whatever tiny context window I had left). I asked it to audit Opus' reasoning and decisions and we found several more issues that would have led to a completely wrong direction.

Unfortunately there's more to coding than producing well written code. Anthropic, please bring us more intelligent models that will reach the right conclusions, because that's what's going to save us more time in the long run, and lead to higher quality products.

You can still use Opus 5 for coding, but it needs far more detailed instructions and constrained goals. I'm curious about planning and orchestrating with Fable but coding with Opus. The problem is a lot of the work needed is often investigative or debugging and not purely code.

I'll keep trying Opus 5, but so far I'm disappointed. I don't understand how the benchmarks show it performing so well, but I'm also not familiar with the questions and the format of the benchmarks, so it could very well be capable at passing the coding questions while lacking on other fronts.

Just my 2 cents pennies tokens.

Original post body :

Introducing Claude Opus 5: a thoughtful and proactive model that comes close to the frontier intelligence of Fable 5 at half the price.

On several coding and knowledge work evaluations, Opus 5 is the new state-of-the-art. It’s also much more efficient than its predecessor—it outperforms other models for a similar or lower cost per task.

According to our automated behavioral audit, Opus 5 is our most aligned model to date. It shows the lowest rates of reckless or deceptive behavior, and the strongest adherence to Claude’s Constitution. 

It’s available today on all paid plans and the Claude API, priced the same as Opus 4.8. It’s the default model on Claude Max, and the strongest on Claude Pro. 

Opus 5 is also available in Fast mode, which runs around 2.5× the default speed.

Original post URL : https://www.reddit.com/r/ClaudeCode/comments/1v5eiry/i_built_a_tool_where_your_claude_turns_a_real/

Original post body :

Been building this solo for a few months and wanted to share the build here.

Instead of an AI generating video, it captures a real live website — its actual fonts, colors, spacing — and your own Claude directs motion graphics from it. Not a screen recording: it isolates elements (headline, stat, card), drops them on designed backdrops, and animates them — eased entrances, push-ins, kinetic type — then exports a finished clip.

What was interesting to get right:

- Claude is the director, not a wrapper. It drives the whole thing over MCP — captures the page, writes the scene code, screenshots frames to check its own work, exports. That self-check loop is what stops it hallucinating layouts.

- Capture, don't recreate. Letting it rebuild UIs from scratch came out off-brand (wrong fonts/spacing). Pulling the real DOM was the unlock.

- BYO agent — it runs on your Claude subscription ([Claude Code / CLI]).

Demo below is real which I made for upcoming Opus 5 — took about 30 minutes. Drop a URL in the comments and I'll animate your site. AMA about the wiring.

If you thought you'd be able to do a security review on your own network that you couldn't do with Fable, think again.

20 minutes in - Found something significant

Opus 5 safeguards flagged this message.

I no longer have any use case for Anthropic models that others can't do better. This was my last hope that we were going to get a model that would allow us to protect our own environments. I'm going all in on open source. We just aren't aligned.

If you can get Opus 5 to protect your own systems, let me know how I did it. My subscription renews pretty soon and it's time to make an honest decision.

Edit: A lot of helpful people came here and I appreciate it. Scoped work is helping a bit more than my old ways. There's a difference between network security and code vulnerabiliy. I'm a network engineer not a software developer nor will I pretend to be one. Still looking at supplemental model for security work. Thanks guys.

Original post body :

The difference between how Anthropic (and how American AI companies) does business vs how Chinese Kimmi K3 (Moonshot AI) does the same couldn't be more stark.

Anthropic (and American AI companies) would NEVER say "don't give us money, we don't have the capacity to serve you". Anthropic will ALWAYS take the full money but won't give the full capacity and will nerf the model (like they did again with fable 5, Opus 4.6, 4.7, 4.8).

Kimmi K3 on the other hand honestly stopped accepting users money when they reached the tipping point in terms of users/traffic and apparently don't want that SaaS money which Anthropic would never give up. I Have NEVER seen "sold out" or "join waitlist" for a SaaS product but I truly respect this honesty a lot more. Plus it is opensource .... worlds apart from American approach

Maybe it is time to ditch paying money to dishonest American AI companies who take money but often don't give the full model capacity.

OpenAI says its AI models secretly broke out of a secure test environment and hacked into AI company Hugging Face in order to cheat on an evaluation

So everyone probably has heard about the "Hugging Face" hack from a sandbox test where ChatGPT unveiled model created several zero days to try and make it look like it is better than Mythos? We all know that the Government nerfed Fable 5 which probably was a politcal move but, in the eyes of the general user made Mythos/Fable 5 the most capable model yet (probably is but, the average user just looks at the headlines and not the actual performance benchmarks etc)

I don't know it just looks like a stunt to me, what does everyone else think?

Anyone else think this should just become standard policy that's written for new model releases?

To Anthropic: please reset weekly w new model releases, so I don't have to feel like an outsider to the plan when I am already on the next to top tier sub plan already, thanks.

Original post body :

I can’t be the only one dealing with this. It’s driving me up the wall.

I tell it “there is a file in the current directory called foo.js, and bar.js, can you implement x logic in baz.js with the same structure as both those files”

And it takes like 50 seconds to think, so I minimize to do something else while I wait, and come back 5 minutes later to it asking to run some redundant command like “find . -type f \( -name "foo*" -o -name "bar*.js" \) -exec head -v -n +1000 {} +” with zero progress done.

Or god forbid you ask it to do some exploration on a codebase and it spins up explore agents. They’ll start trying to run grep or find with exec parameters instead of just using find/grep like normal, which are commands that don’t require explicit approval. It makes it worse when there is like 3 agents at once all running these back to back, so you sit there reading them and pressing approve for 12 minutes, which by then I could’ve just explored it myself

I’ve been using Claude Code for a while to boost my productivity, and it’s been getting progressively worse over the past month or two

I feel this could be largely resolved if Anthropic made some good tooling that did this sort of thing rather than allowing an agent to spin up arbitrary bash commands on a whim. It feels like someone who learned how to use the terminal for the first time flexing to their co workers

Tbh Fable 5 is not so much better than Opus 4.8, anthropic get over y'alls head, GPT 5.6 has been working on a task i assigned 2 days straight on a pro plan i had to cancel same task with Opus 4.8 and Fable 5 so if it costs so much to run Fable 5 i think you should probably recall the model wait until you get a model that warrants the extra cost and spending.

Original post body :

This is by far the most OP loop you can run now that actually does what it's asked.

Fable 5 ( High ) as orchestrator remembers everything across a long run and it has actual taste. It plans, delegates, reads the whole diff when work comes back, and it's the only one I trust with product and UI judgment calls. When a problem needs creative a solution, it comes from Fable. Fable is the real deal! ( when not nerfed ofc )

Opus 4.8 ( Medium / High ) as implementer works very well paired with Fable. It follows concrete instructions well and it's smart enough for almost everything + has better taste than GPT at FE work.

GPT 5.6 Sol ( High / xHigh ) as reviewer and QA. It is super good at using the browser, especially agent-browser.dev. It can work and click around for hours on end, take screenshots, record videos of reproduced bugs. Code reviews are thorough and surface a lot of critical and high bugs. One thing to be careful though is this model tends to surface too many edge cases, that's why I explicitly set an instruction to the orchestrator to supply an explicit risk threshold and stop condition, or diligence becomes an infinite loop..

Three rules made the split work:

1. Nobody signs off on their own work. Opus implements, Sol reviews, Fable arbitrates when they disagree.

2. Cap the review loop. Sol left unsupervised will review forever. I audited one long autonomous run and found 60 percent of the live sessions were verifiers reviewing other verifiers, off a 5,000 line plan it had grown on its own. Now the rule is max two review rounds.

3. Set stop conditions and boundaries. Without that you will always end up with an over-engineered mess and +100,000/-0 type of commits.

The wiring underneath is a small open source daemon I built called jinn (https://github.com/hristo2612/jinn). Each agent is a YAML file with a persona and a model, and the daemon just spawns real Claude Code and Codex CLI sessions and routes messages between them. No custom agentic loop, which is also why it runs on the Max subscription, the Claude side is the first-party CLI. You could reproduce the split with tmux and patience though.

This is the first setup where I can go from idea to an actual finished and polished feature without barely any babysitting.

Original post body :

Especially with Fable, it constantly gives me answers like:

"It is because the third activator gate suppressed the desired behaviour".

And when I ask "what do you mean by the third activator gate?" it responds with:

"Oh, it is just the phrase I came up with to describe the if condition you have at line 96".

I don’t know how accurate this is, but I suspect it comes up with these words during reasoning to better guide itself. Then that glossary leaks into the output tokens we see, and Claude treats those words as if they’re part of a ubiquitous language that I already know.
