In addition to big models, these AI capabilities can also be wasted

The last article published a free cross-section review of the big model API, and several people asked the same question: In addition to the big model, what other AI capabilities can be used for nothing?

I wanted to make a list. But halfway through the list, I found that this list was worthless. There is a large list of "fifty free AI tools" on the Internet. The problem is that half of them are "pseudo-free". The front page says Free, but you will find that the generated pictures have a big watermark and you have to open a membership if you want to remove them. The free quota is given to you five tickets a month, but you will be gone if you use them twice. Or you can only have low-definition ones for free, and you will have to pay for HD.

So this article does not stack tool names. There are two things to talk about: how to recognize fake free money at a glance, and a few points that are rarely mentioned in other people's lists but can really get useful things for free.

Let's first talk about how to identify fake products for free. I checked a batch of tools, and there were only a few tricks for "pseudo-free":

First, it carries a watermark. You can use it for free, but if you put a watermark on the thing you come out, you can't use it seriously, forcing you to pay to remove the watermark. This is the most common transformation routine.

Second, you need to register, tie your mobile phone, and even ask for an invitation code. Circle you in before using it.

Third, the resolution wall. I'll give you double magnification for free, if you want quadruple, if you want HD, pay.

Fourth, the credit system will give you a few quotas a month. Some free versions only have five pictures a month, but they are gone after two uses.

Fifth, leave good models to paying users. You can use the free version, but use the old and weak model, and leave the good ones to members.

One word remember: When you see "free", first find out what it makes money from. The place where it makes money is the place where it is buried. Free products that really have no commercial pitfalls are often open source or the ones that manufacturers use to divert and do not expect it to make money at all.

After recognizing the pseudo-free nature, I said a few points that I had verified that I could really get useful things for free. There are a few things that are rarely mentioned in other people's lists.

Dialogue and writing are the simplest. The web versions of several free large models in China, such as Doubao, Kimi, DeepSeek, Smart Spectrum, and Tongyi, are all free, directly connected in China, and do not use ladders. They are enough for daily writing and asking questions. To plug it into your own program and use it in batches, read a free API cross-section review.

Voice dubbing , this is a real treasure that many people don't know. The "read web pages" function when you use the Microsoft Edge browser is a good set of Microsoft neurophonetics. There is an open source library that can directly extract this set of white prostitutes. There are more than 200 sounds and dozens of languages. There is no need for API keys or registration. You can also adjust the speed and tone and export subtitles. Use it to dub videos and listen to books, and the effect is much better than most free TTS. One thing I have to tell you the truth: This usage steps in the gray area of Microsoft's terms of service. Microsoft means that this service is only for Edge reading. The open source library in the community has been running steadily for three years without being blocked, but if you want to use it as a commercial product, consider this risk yourself.

Picture enlargement and repair , recommend an open source one called Upscayl. It is completely free, open source, and runs on your own computer. There is no watermark, no limit on the number of times. It can be enlarged up to 16 times. It is very easy to use to repair old photos and pasted pictures clearly. It's exactly what "really free" should look like: open source, something that runs locally, and doesn't need to rely on watermarks and members to make money. The price is that it eats graphics cards. If your computer's graphics card doesn't work, it will take several minutes to zoom in.

Translation , the easiest thing is to directly turn the large model over. To batch and connect programs, Tencent and Youdao have free quotas of several million characters per month. The translation of our own projects is for free on Tencent. Five million characters a month is free, which is enough for daily use.

Making pictures and making videos , that is, domestic products such as Dream, Doubao, Tongyi Wanxiang, and Keling all have free quotas, which can produce pictures and produce Short Video for a few seconds. But I have to remind you that this area is the hardest hit area with pseudo-free: the free amount is small, the queue is long at peak times, the ones that come out often carry watermarks or limited resolution, and good models require members. You can taste it and play with it, but it is unrealistic to expect it to produce you stably. Moreover, these free quota policies have changed rapidly, and the specific amount given will be subject to the official's approval at that time.

The last two traps must be known before you go to prostitution for free. They are much more important than saving a little money.

First, the price of free is often you. The copywriting, pictures, data you feed free tools, and the terms of many tools write models that may be used to train them. Don't put confidential company materials, personal privacy, and unpublished things into free tools. There is no free gift, your data is the "fee" it charges.

Second, something generated for free does not mean that it can be taken for commercial use at will. Commercial authorization for pictures, dubbing, and copywriting generated by free tools is another matter. Some free versions clearly state that commercial use is prohibited, and some copyright ownership is vague. You need to use these to receive business orders and sell products for money. Before you start, you must read the authorization terms clearly, otherwise you will save tool money and lose court money.

AI for free prostitutes can collect a lot of real things, but the word "free" has never been really given for free. First understand what it makes money from, keep sensitive things in your hands, and see clearly the authorization before commercial use. Only when you see the cost and collect it can you feel at ease.
