Artificial Intelligence (AI) has seen rapid advancements in recent years, with generative AI emerging as one of the most powerful tools in various industries. From text generation to image synthesis and code completion, generative AI has transformed the way businesses and developers approach automation and creativity.

For those looking to integrate AI-powered functionalities into their projects, APIs (Application Programming Interfaces) provide a straightforward way to access powerful models without requiring extensive machine learning expertise. However, many AI APIs come with hefty subscription costs, making it crucial to find free alternatives that offer robust capabilities.

In this article, we explore the best free generative AI APIs available in 2025, covering their key features and use cases.

This was never in question

> Very few are trying to understand why things are working

What is in question is why this is given so little attention. You can hear Neel talk about this himself. It is the reason he is trying to rally people and get more into Mech Interp. Which frankly, this side of ML is as old as ML itself.

Personal, I believe that if you aren't trying to interpret results and ask the why then you're not actually doing science. Which is fine. There's plenty of good things that come from outside science. I just think it's weird to call something science if you aren't going to do hypothesis testing and finding out why things are the way they are
I often fall asleep while watching Netflix, and since there’s no built-in sleep timer, I built a simple browser extension to fix that.

This extension automatically pauses playback after a set time, so you don’t wake up to autoplayed episodes. It works not just on Netflix, but also on YouTube, HBO, Apple TV+, Twitch, Kick, Amazon Prime, and many more. Just install it, set a timer, and enjoy your show without worrying about bingeing all night.

It’s lightweight, open-source, and works directly in the browser. Would love feedback from the community!
I used AwesomeWM for the longest time before switching to Wayland where I used Gnome because none of the existing WMs seemed interesting at the time. I tried riverwm for a bit but it didn't work for me either. But lately I've been super intrigued by Niri -- it feels fresh and exciting. I've been keeping an eye on it and I can't wait to try it out!

Yes, but it's user agent UI which is not really good in any of them.

Good error messaging is important and having styleable semantic elements would be helpful. It's tricky because you often need more than one error message per input, not just "required" but too big, too small, wrong format, etc.
Thankfully the that doesn’t describe the majority of non-commercial, or even commercial, requirements.
> We do have road signs that proclaim: "New signage" or "New road system" etc. The locals know what has changed already and non locals are encountering it for the first time anyway, so why bother.

I'm not sure it's as absurd as it sounds. Do you look at the signage you pass every day? I suspect I don't.

When they put in a new stop sign near where I live (in the US), things were less safe for a long time because people consistently drove through it without slowing. Since this was not a consistent problem with any other stop sign nearby, I believe it was not willful disobedience but people so used to there being no stop sign there that they literally didn't see it.

(Even with literal neon pennants on it, people kept driving through it anyway, but you'd at least sometimes see people skid to a stop partway through the intersection, presumably as their brains caught up. And eventually it penetrated locals' consciousnesses, and now they stop.)
But you have a choice, you don't have to implement all of C++/Rust.

The beauty of C is that it allows you to pick your level of complexity.

Parkinson shows how you can go in to the board of directors and

I find this cultural divide exists predominantly among mathematicians who consider existence proofs as real mathematics.

We ban e-bikes on many trails in Colorado, and I'm really glad we do:

1) MTB trails are high-maintenance. People riding more miles on heavier bikes means more wear and tear.

2) Their higher speed messes with the flow of traffic. In Colorado, I don't have to step off the trail much to let folks pass from behind. When I ride in other places that allow ebikes, it's pretty obnoxious to be letting them by.

3) They allow inexperienced folks deeper in the back-country. I had to go on a rescue with my S&R crew to assist a dehydrated e-bike rider with a dead battery 25 miles back to the trailhead. It was a very long day. People who go that far out are usually in far better shape and better prepared than the average rider.

4) They let less skilled riders on more difficult trails. This means brake bumps before the berms, trail widening, and ride-arounds appearing next to intimidating features.

No attack on you personally, I've ridden them extensively to train for downhill races and completely understand they can make the sport a lot more fun without having to grind the fitness aspect. However, myself and most other folks I come across in MTB, rescue, and trail building communities see some major systemic issues with their increased adoption.

I'm providing this perspective here because I think it's very relevant to the discussion on exoskeletons' potential impact on outdoor recreation. More hikers putting in more miles when they could get the same level of exercise staying on more beginner-friendly trails causes problems.

I do love the aspect of letting folks who would otherwise be unable to participate in these pursuits enjoy them, but I think Colorado's policy of limiting electrical assist to high-traffic beginner trails for bikes would be well adapted to hiking if these become a thing.

Follow up. Do you have an hypothesis why Claude performs much better than the rest at these tasks?

Is it just because Clause is the best at coding and the API is code? (not very interesting). Maybe if the API required the llms to write in poems, the best LLM at poetry would win...

Or is it because whatever makes claude good at coding, also makes it good at mathematical-like tasks. This is more interesting, as it would show some transfer learning. It would also suggest if you're doing training for a specific task, you would also benefit from training adjacent tasks e.g. if you're training for maths you could benefit from training coding. I believe this is actually true for humans.

And would you know how to check whether if any of the above hypothesis is correct?

The concept of "admin" is not a black and white concept, it's a spectrum.

Every iPad user is an "admin" of their device. Apple isn't stopping you from "administering" it.

There are limitations to the device but every device has limitations somewhere.

On that spectrum, the iPad is a much less limited device from a software and hardware standpoint than a lot of other devices, such as game consoles, point of sale terminals, medical devices, etc.

A lot of devices are intentionally designed with safety guardrails for very good reason.

For example, an inexperienced end user should not be able to freely reprogram the firmware on a robotics system used for surgery. A system like that is very intentionally shipped with guardrails that prevent the owner of the device from making dangerous modifications.

Other guardrails exist for other hardware where the end user is given some freedom but still kept from destroying the hardware or harming themselves. For example, your processor or graphics card won't let you fry the system by exceeding thermal limits, but they may still allow you to change settings like clock speeds and voltages. These limitations generally make sense and I would not really appreciate if AMD allowed me to accidentally fry my processor. A car infotainment system that allowed you to play videos or games while you drive or disable driver attention monitoring during self-driving would be grossly negligent.

I personally think the "everything should and must be open source" crowd takes a good concept way too far and essentially wants to dictate business models and approaches to safety and security.

I would support a more moderate approach that would force Apple to support more of a level playing field for things like alternative app stores, interoperability, and fair competition with alternative software, software/hardware end of support anti-e-waste regulations, but forcing them to divulge schematics and allow you to modify sensitive parts of the hardware like the secure enclave is not particularly beneficial. Just my opinion, though.

And finally, I’m firmly in the camp that I’m not going to tolerate a shitty solution just because it’s open source. No, I’m not going to use a $1000 Librem 11 tablet that’s at least 4x-12x slower than an iPad Pro that costs the same amount of money.

You just summarised (nearly) everything a mathematician can get out of that computerised proof. That's unsatisfying. It doesn't give you any insight into any other areas of math, nor does it suggest interesting corollaries, nor does it tell you which pre-condition of the statement does what work.

That's rather underwhelming. That's less than you can get out of the 100th proof of Pythagoras.

Ask HN: Specialize in one domain at the expense of others?
I know focus (specialization) is important to obtain a high degree of skill and knowledge in a given domain.

However, I have a number of hobbies that are in a tangential domain to my specialization with little overlap. I always feel bad when I spend time doing them when I could be doing more work in my specialization. How do you overcome this? Is it something you can overcome, or just something you deal with?

Safari's extensions had a similar change-over to a ManifestV3-like system, with the same arguments: increases performance (very important for mobile) and puts more safeguards on extensions doing funky privacy-hostile stuff.

Yes, ManifestV3 nerfs adblocking, and Google loves that side effect. It will hamper Brave' internal adblocking engine.

I think the big interesting question is: if Brave figures out how to add improvements to ManifestV3 that aid adblocking without sacrificing performance or privacy/security, will Google accept the PRs?

They opted firefox users into a data collection scheme they call PPA which works kind of like FLOC and uses the browser to gather information about what you do online, then they sell that data to advertisers by first sending it to yet another a third party who will assemble that data into reports for the advertisers. Then they basically said firefox users were too stupid to be trusted to opt-in, and it would be too hard to explain to such dumb users how selling their data was a good thing, so Mozilla had no choice but to force it on everyone by default without telling them about it.

Brave has built-in functionality that can replace uBO, but it doesn't replace all of the other Manifestv2-only extensions that are not necessarily adblockers. For example https://libredirect.github.io/faq.html#chrome_web_store

Yes, I also found the description a little weird because of the emphasis on linear-time parsing.

Yes, for that particular plot of land, which they already owned, the land price is not what prevented construction. That particular project’s failure is not a major driving force of the price of living in Burlington.

The fact that 2 acres costs $3MM is a major driving force.
The other side of this is that light (EMR) attenuates exceedingly rapidly in matter. Much (though not all) of it will pass through a few tens or hundreds of kilometers of atmosphere, but a distressingly thin piece of solid matter (or many liquids) will block or scatter it beyond all detection save residual thermal noise. (The fact that we can transmit light through hundreds or thousands of kilometers of solid glass is worth marvelling over.)

Sound, being a vibration of matter itself rather than an electromagnetic field, actually often travels better through matter, particularly those low frequencies which are transmitted through structures or the ground itself.

But yes, the far more energetically intense electromagnetic radiation is generally far more easily addressed than far weaker sound eminations.

Protected health information (PHI) under U.S. law is any information about health status, provision of health care, or payment for health care that is created or collected by a Covered Entity (or a Business Associate of a Covered Entity), and can be linked to a specific individual.
