r/ClaudeAI on Reddit: Easiest way to use Claude API to avoid daily limits
April 13, 2024 -

I switched from GPT-4 to now mostly using Claude 3, but the daily message limits are annoying. Also, I really like the ChatGPT interface better. Claude is missing a features like a button to STOP when it’s streaming a long response that is bad.

I use this project to get my own front-end for Claude 3. It uses the API so I have no daily limit to messages, and I get to use a chat interface that has all the features ChatGPT has. Even if you’re not very technical, it’s easy to set up. https://github.com/allyourbot/hostedgpt

It supports both GPT-4 and Claude 3 so it lets you do really cool things like you’re having a conversation with one of them and you don’t like it’s response, you click the “re-generate” button and you can switch assistants mid-conversation. This animated gif demonstrates. The other day I asked it a technical question and switched assistants and finally got the right answer! https://p425.p0.n0.cdn.zight.com/items/ApuPWXb6/c413f8dc-519f-4f5f-b250-45a7688b99d1.gif

It’s also really nice to have access to both GPT-4 and Claude 3 without committing to $20 per month to either. I just get charged for what I use. For example, OpenAI released a new version of the GPT-4 model last week I’ve been going back to it to see how much they improved it. (I don’t have a well-formed opinion yet).

r/ClaudeAI on Reddit: Claude API limits
September 13, 2024 -

I’ve been using the free chat on the website for 3.5 sonnet for coding but it keeps reaching the limit. Is the API unlimited or at least way longer? And does the API work as good?

I HAVE ALREADY TALKED ABOUT IT, SO I WILL JUST COPY TEXT BELOW ================================================= SOLUTION Using Claude through API is solution to many problems (limits reached, Claude errors etc.). In API you pay small price per message (like $0.005). Recommended way of chating with Claude API is through bring-your-own-key (BYOK) app. Ones I would recommend are LibreChat , TypingMind  and CheapAI . They even give Claude additional abilities such as web browsing. First two are really powerful, but potentially expensive, require complex setup/maintenance or are overwhelming to use. CheapAI is my free personal project and easiest/fastest to use, but simpler then first two. However, it has many powerful features and is more than enough for most tasks. It is designed to be as beginner friendly as possible. I use Claude official app as much as I can, and jump to BYOK app when I hit limit in official app. With this approach, I save 15€-20€ per month, because I remain on free plan and do not need to subscribe to pro. I would recommend you do the same. SOLUTION SUMMARY When you official Claude app starts being annoying (limit reached, model being stupid etc.), switch to BYOK app. Use TypingMind/LibreChat if you want something really powerful, but you are ok with additional paying or potential overwhelming complexity. Use CheapAI if you want to fast/easy solution with little less features, but still more then enough for most tasks. Me and my friends use it for same reason as you, coding, and for that it is perfect. Links are above!

If you set a amount of maximum $ for API use the API will tell you you've reach the API limit. I was set 10$ per month of limit thinking that it's for API auto renewall but i've reach 10$ of API use in this month and stopped. Remove or raise your montly API limit in Anthropic API Billing section, Resolved.
