ChatForge: A free, open-source AI chat client with 300+ models (GPT-4, Claude 3, etc.)—no subscriptions, pay-per-token!

I’ve been working on ChatForge—a no-BS, open-source chat client that lets you access 318+ AI models (GPT-4.1 Mini, Claude 3.7, Qwen, Gemini, etc.) from one dashboard. No upfront costs, no monthly fees—just pay for tokens you actually use.

Why bother?

Free-tier models: Test drive without even adding a payment method.
Persistent chats: Name/organize convos like files (RIP losing your 2am AI rants).
Customizable: Set default models, API keys, etc.
Simple UI: Not a design award winner, but it’s clean and functional (I’m a dev, not a designer—sue me).

It’s 100% free and community-driven. I’d love feedback (or contributions if you’re into Python/Django).

Try it or roast it:

P.S. If you’ve tried similar tools (like OpenRouter’s web UI), how’s this compare? Honest takes welcome.

How would you handle achievements and achievement progress n a Django app?

I’m working on a Django web app where I want to introduce badges/achievements for users — things like:

* Play 10 random quizzes in a day
* Finish 100 quizzes in total
* Play 7 days in a row

Here’s the basic model setup I’m considering:
```
class Achievement(models.Model):
code = models.CharField(max_length=100, unique=True) # e.g., 'play_10_quizzes'
name = models.CharField(max_length=200)
description = models.TextField()
icon = models.ImageField(upload_to='achievement_icons/', null=True, blank=True)

class UserAchievement(models.Model):
user = models.ForeignKey(User, on_delete=models.CASCADE)
achievement = models.ForeignKey(Achievement, on_delete=models.CASCADE)
unlocked_at = models.DateTimeField(auto_now_add=True)

class Meta:
unique_together = ('user', 'achievement')
```

How best to save and calculate/track user progress toward an achievement?

I’ve been reading that using Django signals might not be the best approach here, and I’m wondering what patterns or architecture others have used.

**Specifically:**

* Do you calculate achievement progress dynamically (on the fly) when the frontend requests it?
* Or do you store progress in the database and increment it every time an action happens (e.g., quiz completed), so reads are faster?
* How do you handle edge cases, like historical data changes or deletions?
* Any tips on scaling this

Why should one write tests?

First of all I will not question whether it is necessary to write tests or not, I am convinced that it is necessary, but as the devil's advocate, I'd like to know the real good reasons for doing this. Why devil's advocate? I have my app, that is going well (around 50k users monthly). In terms of complexity it's definetely should be test covered. But it's not. At all. Yeah, certainly there were bugs that i caught only in production, but i can't understand one thing - if i write tests for thousands cases, but just don't think of 1001 - in any case something should appear in prod. Not to mention that this is a very time consuming process.


P.S. I really belive I'll cover my app, I'm just looking for a motivation to do that in the near future

strif: A tiny, useful Python lib of string, file, and object utilities

I thought I'd share **strif**, a tiny library of mine. It's actually old and I've used it quite a bit in my own code, but I've recently updated/expanded it for Python 3.10+.

I know utilities like this can evoke lots of opinions :) so appreciate hearing if you'd find any of these useful and ways to make it better (or if any of these seem to have better alternatives).

What it does: It is nothing more than a tiny (\~1000 loc) library of \~30 string, file, and object utilities.

In particular, I find I routinely want atomic output files (possibly with backups), atomic variables, and a few other things like base36 and timestamped random identifiers. You can just re-type these snippets each time, but I've found this lib has saved me a lot of copy/paste over time.

Target audience: Programmers using file operations, identifiers, or simple string manipulations.

Comparison to other tools: These are all fairly small tools, so the normal alternative is to just use Python standard libraries directly. Whether to do this is subjective but I find it handy to `uv add strif` and know it saves typing.

boltons is a much larger library of general utilities. I'm sure a lot of it

Using Django+Sqlite in production

I've been researching the use of Sqlite in production and came across this thread which has some resources, mainly about the benefits and also how to performance tune Sqlite.

My intent right now is to keep my app on Sqlite. The application is a B2B app with limited number of users, and it is not write heavy (a few hundred writes per day). It also simplifies my tech stack.

I'd like to check if someone has resources specific on how to deploy and run a Django+Sqlite app.

Over in the Ruby on Rails world, I saw a movement to help developers achieve this, and was wondering if there is something equivalent in the Django.

Cogitator - A Python Toolkit for Chain-of-Thought Prompting

GitHub Link: [https://github.com/habedi/cogitator](https://github.com/habedi/cogitator)

**What my project does**

Cogitator is a Python library/toolkit that makes it easier to experiment with and use various chain-of-thought (CoT) prompting methods for large language models (LLMs). CoT prompting is a family of techniques that helps LLMs improve their reasoning and performance on complex tasks (like question-answering, math, and problem-solving) by guiding them to generate intermediate steps before giving a final answer.

Cogitator currently provides:

* Support for OpenAI and Ollama as LLM backends.
* Implementations for popular CoT strategies such as Self-Consistency, Tree of Thoughts (ToT), Graph of Thoughts (GoT), Automatic CoT (Auto-CoT), Least-to-Most Prompting, and Clustered Distance-Weighted CoT.
* A unified sync/async API for interacting with these strategies.
* Support for structured model outputs using Pydantic.
* A basic benchmarking framework.

The project is in beta stage. The README in the GitHub repository has more details, installation instructions, and examples.

**Target audience**

* AI/ML researchers looking to experiment with or benchmark different CoT techniques.
* Python developers who want to integrate more advanced reasoning capabilities into their LLM-powered applications.

In general, CoT could be useful if you're working on tasks that need multi-step reasoning or want to improve the reliability of LLM outputs for more complicated queries.

**Why I made this**

I started developing Cogitator because I found that

The admin can generate question papers in form of both pdf and word. I am unable to find a way to let users to add questions that has equations or formulas. I tried using tinymce and mathjack but it doesn't seem to support all formats (like the bigger fractions). I also tried rendering latex to text or image and is too complicated for me to understand how to make it work properly. I do not want to paste the equation/formula as an image in the word file, I need to to be in proper human readable format. I want the outputs both in word and pdf formats. Please help.

I built my own asyncio to understand how async I/O works under the hood

Hey everyone!

I've always been a bit frustrated by my lack of understanding of how blocking I/O actions are actually processed under the hood when using async in Python.

So I decided to try to build my own version of asyncio to see if I could come up with something that actually works. Trying to solve the problem myself often helps me a lot when I'm trying to grok how something works.

I had a lot of fun doing it and felt it might benefit others, so I ended up writing a blog post.

Anyway, here it is. Hope it can help someone else!

No, not every website needs to be an SPA. Built something with Django—fast, clean, and people love it.

I just launched a small project using plain Django (no SPA, no fancy frontend frameworks).

It’s fast, clean, and people love using it.

I see so many projects defaulting to SPAs, even when it’s not necessary. Django let me move fast, keep things simple, and focus on the core experience—not on wiring up a complex frontend stack.

Honestly, that’s what I love about Django. It gives you everything you need to ship something solid without overengineering.

Also—thank you to this subreddit. I’ve learned a lot here. If anyone’s curious about the stack or wants to ask anything, happy to chat.

My journey after 1 month on internship using django

I have been using Django almost for a month (The first days in the company I did nothing. I was only meeting new people).

They told me to use whatever I want, so I chose Python because I'm interested in machine learning so I saw it as an opportunity for my future. They want to create automation and I didn't know where to deploy it so I decided to deploy everything I do for the company in the web then I decided to use Django.

I have learned a lot since then, sometimes I get stressed but reading code and with AI tools I reach to fix the errors I have on my code but of course I have a ton to improve and I'll do it with the time, I just started my journey in this world and I'm so happy for it because since I was a kid I love technology

Tuples vs Dataclass (and friends) comparison operator, tuples 3x faster

I was heapifying some data and noticed switching dataclasses to raw tuples reduced runtimes by \~3x.

I got in the habit of using dataclasses to give named fields to tuple-like data, but I realized the dataclass wrapper adds considerable overhead vs a built-in tuple for comparison operations. I imagine the cause is tuples are a built in CPython type while dataclasses require more indirection for comparison operators and attribute access via __dict__?

In addition to dataclass , there's namedtuple, typing.NamedTuple, and dataclass(slots=True) for creating types with named fields . I created a microbenchmark of these types with heapq, sharing in case it's interesting: https://www.programiz.com/online-compiler/1FWqV5DyO9W82

Output of a random run:

tuple : 0.3614 seconds
namedtuple : 0.4568 seconds
typing.NamedTuple : 0.5270 seconds
dataclass : 0.9649 seconds
dataclass(slots) : 0.7756 seconds

Flask is driving me crazy

ok so i started learning flask as part of a course im in. At first, it felt like it was easy with some all-in-one code ive made. Like managing the routes, using url_for, creating the connection with the database. Then i tried to make the flask tutorial from their website, now i feel the more dumb than i used to, lol. i think they just throw code on the screen and you gotta copy, i mean, i can totally understand what the code does by reading it, but i cant imagine me learning anything from it. I dont know if i am going to be able to get all of this stuff in my head.


Is there any other place i can learn flask or Python webdev thats does it slowly and/or in a better way?
