A follow-up to my earlier Claude vs OpenAI chess matches. Last time Fable 5.1 lost to GPT 6 Astra, so I ran a rematch with the newest Fable 5.2 and swapped colours: Claude plays Black this time. All earlier games are on r/PersephoneNotepad: https://www.reddit.com/r/PersephoneNotepad/

Same setup as before: both models at high effort, fresh sessions, no engines or outside tools. White: GPT 6 Astra (Codex CLI). Black: Claude Fable 5.2 (Claude Code). The video plays at 4x speed (the game took 54 minutes).

Result: 1-0. Astra mated on move 76, after Fable lost its queen to a careless check while a bishop up.

My observations

• Astra used my whole Codex 5-hour limit on this one game, from 100% to 0%. My first attempt at this match, started without a full window, stopped mid-game when Codex hit the limit.

• Fable was much slower overall: it used 65.8% of the thinking time, Astra 34.2% (measured from the move timestamps in both models' logs). Most of Fable's moves were actually quick; the gap comes from a few long thinks of up to about 3.5 minutes.

Results so far

Here's a free in-browser flight sim (starship.kmlabs.co) for the last minute of Starship flight. Can you land it? I did...once ... after many many tries (and only once so far)

Space bar for throttle and trackpad to steer. Once you realize your trajectory is FUBAR just tap R to quickly reset.

And here's claude's write-up on how this was made (using fable 5.2):

How it was built

1. Physics first, with no graphics. The flight model is a rigid body with six degrees of freedom, stepped at 240 Hz. It has component aerodynamics for the body and four flaps, three gimballed engines, wind, and contact with the catch arms. It runs in Node as well as the browser, so it could be tested headless from the start.

2. A reference pilot to prove it's flyable. An autopilot flies through the same stick and throttle a person has. If it can't catch the ship, the controls or physics are wrong, and that caught several real problems (for example, half-folded flaps rolling the ship in sideways airflow).

3. Then the 3D world. Three.js on WebGL, everything procedural: sky, coastline, launch site, tower, ship, plumes, dust, explosion. Profiling showed the cost was per-pixel shading at Retina resolution, so the sky was baked to a cube map, rough surfaces were given cheap shading, and particle counts were cut. Frame cost came to about 5–8 ms on your M3 Max, measured before the catch rework and not re-measured since.

4. Your corrections reshaped it.

   - Pad landing became a tower catch: legs were replaced by catch pins, swinging arms and tower collision.

   - The autopilot became a takeover you can engage mid-flight.

   - The throttle was redesigned after you found it unflyable: releasing Space now settles just under hover instead of cutting to zero.

   - Tower shadows were softened, and arrow keys now orbit the camera.

   - A carrier-style approach display was added: meatball, lineup needles and spoken-style calls.

5. Published. A private S3 bucket behind CloudFront in account2, with a certificate and DNS records for starship.kmlabs.co, all in two small CloudFormation stacks. infra/deploy.sh rebuilds and republishes.

I need to implement a license system (maybe online) for a PC app I have.

I have 30% Fable 5.2 usage left of my Pro account. Should I use Fable 5.2 to write the plan and Opus 5.5 to implement it? Or should I just have Opus 5.5 plan and implement it?

I know with all frontier online and local models, any license system will eventually get broken. But I still need to try at least. Also, does anyone have any tips on how to prompt or implement it in a way that Claude and ChatGPT will refuse to break the license system/encryption if a users ask it to?

Disclosure: Claude wrote most of the code. I’m not an experienced app developer. I designed it, made the calls and tested it on my own PC every day.

What it is: Wintainium, an Obtainium-style app manager for Windows. It tracks about 28 emulators, frontends, mods and tools from their release pages (GitHub, GitLab, Forgejo, itch.io, Dolphin’s feed). It shows what’s outdated in a WPF window and updates each app the right way: EmuDeck’s installer, the app’s own updater, an installer, or a zip unpacked after a backup.

How we built it: it started as “scan what I have installed,” turned into a CLI, then a GUI, then a public repo. I described what I wanted, ran each version on my real setup, pasted back errors and screenshots, and Claude fixed and extended it. It was always shaped by what actually broke on my machine.

What I’d tell others:

• Test on the real environment early. The sandbox passed things my PC didn’t.

• Set safety rules up front, like “never delete anything matching just this name” and “never allow threats.” Claude stuck to them.

• Keep personal config, tokens and cache gitignored from day one.

About the only thing I feel Claude lags behind some of its peers is with its ability to take a document and give it a polished, profesional feel. Of course, this could be my use of it. Any good tips?

I remember sometimes opening Claude to find my weekly limits had been reset well before they were supposed to. It was always a pleasant surprise.

Now they let you choose when to do it. Does this mean they will not again surprise us with unexpected resets?

Planning to take exam soon, but my company doesn’t pay for it, so wanna check are there any discounts, black friday options? 😅

I've been using Claude a little over a year now. I used to use it on Perplexity, as I had a free year of their pro subscription, but I swapped directly to Claude after my subscription was up. Lately, since September, I've been using Claude to help me study with college and notice I could maybe use it to help learn 2-3 course concepts in a day before I reached my limit. Now, since they announced their IPO, I feel like I've been getting a lot more usage. I'm not sure what it is exactly, but I've been using Sonnet 5.5 since its release, and other than usage, I've not had many issues. I'm just wondering if anyone else noticed maybe their usage allowance went up or if efficiency increased for that model?

I'm working with Claude on a tool for running D&D 5e games for a few weeks now, made to band together all kinds of stuff usually done by multiple tools (note taking, DM screen, maps, combat, rules) in one integrated app. Focus here is on face to face games run manually, with a synced player mobile app on the way too.

I'm very new to all of this, and while I'm astonished from sense of discovery in putting it together and seeing what happens, I'm also curious to know if anyone here did something similar and can share their experience and any tips.

Hey all, quick question that turned into a friendly argument at work :/

I use Claude Desktops Code tab, with Obsidian for my notes. My boss says I should switch to the CLI in VS Code because it works better and uses WAY fewer tokens. I tried both and honestly didnt notice much difference.

What do you guys use, should I switch?

No need for a long reply. If you know of any research or tests on this just drop a link. I m genuinely curious

hi all, so I'm making a software-as-a-service application with Claude Code. I know Python and Flask, which is what I'm using for the project. Is this something I can monetize or would you recommend going back and revising the codebase myself? I know the answer seems obvious, and I'm going to rewrite it myself regardless, but I could use the advice. Thank you

PiP Studio puts any window, screen, or part of the screen into a small always-on-top picture-in-picture. It can also control PiPs from other apps (Chrome, Firefox, Discord) and works fully with a game controller

I don’t know C#, so Claude wrote all of the code in the Claude app. I described features in plain language, built each version on my PC, and sent back compiler errors and screenshots of anything wrong. When it got stuck on a bug (like black bars around Discord streams), I had it add logging and sent it the results until it found the cause. It also wrote the installer and the GitHub release setup.

It’s free and open source. Grab the installer or portable version here: https://github.com/NauticalNoodles/PiP-Studio

(I had to write this slop of a description cause the bot didn't like the previous human slop I wrote)

I mostly made this app because I wanted something a bit niche and a lot of the tools out there are good but just aren't what I'm looking for.

Hope you like it as much as I do :D

From a physics based simulation of 2 2d balls with different powers fighting, based on something seen on YouTube. Could people buy the game for like 5$ or would this be monetizable on YouTube?

Wanting money to pay for college so I was wondering if this could be a notable project

Tumblebuds: The Journey Home. You guide a group of little Buds home by handing them jobs: dig, build, float, bash through walls. 30 levels across beach, sea, desert, mountains and space.

Play it here (free, no install, works on phone, tablet and PC):

Built entirely with Fable 5.2 in Claude Code. The whole game is a single HTML file: 3D graphics, music, the intro film and all levels. I gave direction and playtested; Fable 5.2 wrote the code.

The levels were designed for my 5-year-old, so don't expect hard puzzles. The voices are placeholders for now.

Feedback is very welcome, especially on how it runs on your device.

Ciao, volevo capire se ha davvero senso combinare i due abbonamenti insieme.
L'idea di base sarebbe capire se ha senso avere go per fare ricerche e e creare Promt e avere Claude pro per creare siti web? Quanto è conveniente? Basta realmente solo ClaudePro?

I'm a nutrition scientist (biochemistry focus), not a developer. Over the last few weeks I built synaptiklabs.org with Claude Code: a bilingual (English/German) reference that shows where a compound acts in the body and rates every popular claim about it against the human studies. It's free to read; a paid tier is planned for later.

What it does: 504 compound profiles (supplements, nootropics, peptides, medicines, drugs), 1,794 rated claims and about 7,000 cited sources. Each claim gets an evidence level from 0 to 4 (what kind of study tested it) and a separate result (benefit, mixed, no benefit, never studied). 47 interactive figures show the mechanism, like the dopaminergic synapse in the video, where you switch between compounds. There is also a compare view, a hype check, a simple/technical reading mode and a glossary. No doses, no shops, no tracking.

How Claude helped, in detail:

Research pipeline: multi-agent workflows draft each profile from primary literature, then separate agents try to refute it. Every DOI and PMID is resolved automatically against Crossref and PubMed, so a made-up citation fails the checks. I set the rating rules and check ratings and key statements myself.

Figures: each SVG figure is built by one agent and reviewed by two independent ones (one for the science, one for design and accessibility) before it is merged.

Code: Next.js static export on Cloudflare Pages. Claude wrote the components and about 1,600 unit tests plus roughly 2,000 Playwright browser tests. Nothing goes to main without green tests, and scheduled cloud runs repeat the checks off my laptop.

Night shifts: I give a goal and a budget, Claude runs agents in parallel git worktrees, keeps a ledger and asks me only for real decisions.

What I learned: Claude is only as reliable as the checks you script around it. The biggest gains came from making every claim verifiable (resolvable sources, validation scripts) instead of trusting the text. Parallel agents also need hard limits: my laptop ran out of memory more than once.

Happy to answer questions about the workflow, or take criticism of the ratings.

I left Gemini a few weeks ago for claude.

I'm in love so far but I have the feeling I don't optimize my usage.

I'm mostly working with proxmox, HA and ARR.

Is there stuff to watch or read to optimize my usage?

I'm on ultra for one month but my own is to pay pro for a year after.

Cheers.

As someone who regularly uses Claude, I've noticed an increasing number of games, mods, and other projects containing very recognizable AI writing patterns. Things like "The name was a warning" are particularly common examples.

In my experience, Claude struggles more than other LLMs with stylistic diversity in creative writing, making these patterns especially noticeable.

I'm currently developing a Minecraft datapack and an accompanying wiki with Claude, and a considerable amount of my time is spent editing its output. That includes removing repetitive sentence structures, unnecessary dramatization, formulaic descriptions, and other recurring Claude-isms.

I think this is something we should discuss more as a community. Learning to critically evaluate and edit AI-generated content is just as important as learning how to prompt an LLM effectively. Simply publishing whatever Claude generates without meaningful editorial input contributes to the oversaturation of AI slop.

I'd also encourage people to spend less time engaging with the anti-AI crowd. They probably aren't your intended audience anyway, and calling them Luddites accomplishes very little.

I'd much rather see this community discussing how to improve the quality of AI-assisted projects, sharing editing techniques, and identifying common shortcomings in Claude's output.

What recurring Claude-isms have you noticed in your own projects, and what have you found effective in addressing them?

Already reached my limit after "speaking" with Fable about an hour on a niche topic. I have to say it truly felt like I was speaking with a capable person. Don't get me wrong. I love Opus but even with 5.5 improvements, reading its generated text is not the best experience in the world. Something always feel off with it. I didn't have that feeling/experience with Fable in my limited exposure to it.

What it is

Distant Clunk is a spooky first person puzzle game set inside a pyramid. You sing three notes to lift relics and carry them to their plinths, and a shout drives back the things that hunt you. There is a short intro tomb that teaches the mechanics, then procedurally generated levels that get harder. It also has a comfort mode and a fixed overhead view for people who get motion sick.

It is free to play: open the link in a browser on desktop, tablet or phone and allow the microphone. No sign-up, no install, no ads. Your voice is processed on your device and never sent anywhere.

How Claude helped

I'm a designer. I have played with game mechanics for years but never had the skills to build one. I wrote the concept and the design direction, and Claude (Fable 5.2, in the Claude app) wrote all of the code. I did not write a line.

The process, over 23 versions so far:

- I gave Claude a pitch: the setting, the voice mechanic, and constraints (run in a browser, stay tiny, no libraries).

- Claude's answer to the size limit was to skip 3D models entirely. The whole tomb is a signed distance field drawn by one raymarched fragment shader, and every sound is synthesized with Web Audio. There are no image or audio files, which is why it is 61 KB.

- Claude wrote the pitch detection (McLeod method) that turns a hummed note into a control, plus the filtering that stops the game hearing its own rumble.

- Claude tested each build itself before handing it over: it ran the game in headless Chrome, fed recordings of humming into a fake microphone, and scripted full playthroughs.

- I played each build on a Mac and a Pixel, described what felt wrong in plain English ("the doors sound squelchy", "it drops the object when I move", "my friend gets motion sick"), and Claude reworked it. The lock-and-release carrying, the hiding enemies and the overhead view all came out of that loop.

- I kept a set of project instructions and a running notes doc in a Claude Project so the design stayed consistent between sessions.

What didn't go smoothly

Phone audio. It still crackles on some Android phones, especially over Bluetooth, and we are a few versions into chasing it. Claude can't hear my phone, so that part is slow guess-and-test.

There are release notes on the title screen (bottom left) that go into how the engine works. It's an early version, so feedback is welcome, particularly on whether it hears your voice properly.

I've always had this picture in my head of what hacking looks like from the inside, so I asked Fable to help me build it in Blender. Honestly can't believe how close it got 😄

I know you guys always ask "ok but how was this made?", so here's the whole workflow:

1. Planning: a "director" agent (a Claude subagent with its own instructions) looked for references online and wrote 3 different scripts, second by second: what's on screen, camera movement, lighting. I picked one.

2. Reference images: ChatGPT drew designs for the key objects, like the rings around the server.

3. 3D models: Tripo turned those images into 3D models. The room furniture is from Tripo too.

4. Motion reference: a short 8-second test clip from Seedance (in Higgsfield) showed how the rings should spin and stop.

5. Building the scene: Claude Code wrote Python scripts that run Blender in the background. They build the scene, set up the camera flight and lights, and render the frames. ffmpeg stitches them into the video.

6. Real game assets: the terminal is a recording from my game, and the device icons are the real LAN View icons.

7. Review: before anything reached me, a "reviewer" agent with fresh eyes rated test frames 1–10 and listed the 3 worst problems. Only then did I get to see it.

Biggest lesson: the first 4 versions had everything built purely from code, and they looked cheap. It started looking good once the objects came from a 3D generator and the screens came from the actual game.

Music is my own, from the game's soundtrack.

I'm a QA Engineer exploring Claude AI and looking to use AI more effectively in my day-to-day work.

I'd love to hear from experienced QA engineers and developers:

1. Which Claude plugins or integrations do you recommend for QA engineers?

2. Which tools or plugins do you use for coding, automation, and debugging?

3. How can I use Claude effectively with Playwright, Python, API testing, and test case generation?

4. Are there any MCP servers, skills, or other integrations that can significantly improve productivity?

5. What does your actual AI-powered QA workflow look like?

I'm looking for practical recommendations, real-world use cases, and tools that you personally use.

Would love to learn from the community. Thanks!

I built this myself, almost entirely with Claude Code.

What it does

I save a lot of dev tutorials on Instagram and YouTube and never open them again. Skwirl takes a reel or post you save, transcribes the audio, reads the text on screen, and writes a short note you can search. It also has an MCP server, so Claude can search those notes.

How Claude Code helped build it

- Claude Code wrote the backend: a Cloudflare Worker with a D1 database, the queue that processes saves, and sign-in by email code.

- It wrote the pipeline that downloads a reel, transcribes it, pulls the on-screen text from frames, and turns that into a structured note.

- It built the MCP server and the OAuth flow, so Claude and other MCP clients can connect.

- I ran several Claude Code sessions in parallel, each in its own git worktree, with one session reviewing and merging the others' work.

- It also wrote the test suite, which is how I catch regressions before each deploy.

My part was the product decisions, the design, and a lot of "no, not like that".

How I use it with Claude

With the Claude Code plugin, Claude searches my saves at the start of a task without being asked. Last week I asked for a scroll-driven parallax hero, and it pulled up a "4 Web Animation Patterns" reel I'd saved weeks earlier and used it as the reference.
