r/ClaudeAI on Reddit: Hitting claude limits almost immediately. It's useless now
January 5, 2025 -

Recently, I'm having to compress 2MB files as hard as possible to even get more than 4 messages into a chat. It seems like claude is functionally useless for anything other than as an alternative to google.
I will litterally hit the limit if I attach more than 3 files to a chat. What is going on?
I'm cancelling my subscription and moving back to OpenAI, even though I hate it's guts

For context, I'm a software engineering student and this particular chat contained, I kid you not, three messages, a single 175KB file and I was trying on the 4th message to attach 2x 2MB pdf files, using 3.5 Sonnet. Compressing the files down to 600kb and it STILL won't work, even trying with a SINGLE file.

I'm getting "You message will exceed length limit, make a new chat". It's so damn awful

EDIT: So it turns out that Claude is absolute TRASH at pdfs, wasting all my tokens and all capacity on trying to process the company logo that appears on each of the 90 pages in the pdf. After fiddling around I finally got a different message specifying something like "this message exceeds image limits". What a shame

EDIT 2: People don't seem to understand that Claude advertises file uploads of 20 files, 30MB max EACH. Hitting the limit with a 600kb file should not be possible and is an enormous oversight

r/ClaudeAI on Reddit: I'm confused about file upload limits
December 2, 2023 -

So I've just done the unthinkable (according to the current mood of the sub) and paid to go pro. I have a single task that I need right now, and it's something that's worked in the past on a free account - discussing a full manuscript.

Months ago, I uploaded a draft in 3 parts (because 1 was too big for a single upload). It accepted the parts totaling 150k words, and we had a very productive discourse on the contents, which was extremely helpful.

Now, I'm trying to upload 130k words for the next draft. It wouldn't even let me upload part 2 as a free customer for the past week (and sometimes not even part 1). Today, after going pro, it's telling me I'm still 14% over the limit for part 3. So going pro clearly upped the tokens, but it's still too small.

Is it possible that the 200k token limit isn't working? Or do even pro users get throttled with tiny token limits during busy times? Is the solution to try this when the US is asleep?

Thanks

EDIT: I cut the manuscript down to 127K words, cutting out all the interludes, and it manages to upload! And after a single reply, it tells me that the conversation is full and I must start a new one. Wow - so I just snuck in under the wire and can only get one paragraph of insight. I don't understand how this was working so well in July and now it seems like there's almost half the capacity, despite doubling the tokens!

It's beyond frustrating how low the limit is especially since i'm paying for the service, if you forget to open new chat every 5 minutes well good bye for the next few hours. And not only you get blocked from one chat, it gives you an offer to use Haiku but that one is blocked as well, like...thanks a lot

Perplexity.ai has a 10MB file limit, which is around 300,000 words if you do not have any images in the file. You MUST upload it as a PDF. Claude’s original maximum file upload was 100,000 tokens, which approximately 75,000 words, but at least on my free account, they have now changed this to to 10MB, which is around 300,000 words.

Claude AI Free vs Pro Limit, User Caps. How to Bypass Them? | Writingmate Blog
October 1, 2025 - For PDFs, Claude 4 and Claude 3.5/3.7 Sonnet can analyze both text & visual content (images/charts) if the PDF is under 100 pages. But with Writingmate multi-model approach, you can do even more with such documents. At the same time, larger PDFs or other models only get the text. So in practice, if your file is very large or in case it has a huge ammount of pages, you better split it to stay within limits.

r/ClaudeAI on Reddit: The maximum output length on Claude.ai (Pro) has been halved (Possibly an A/B test)
September 1, 2024 -

Here is the transcribed conversation from claude.AI: https://pastebin.com/722g7ubz

Here is a screenshot of the last response: https://imgur.com/a/kBZjROt

As you can see, it is cut off as being "over the maximum length".

I replicated the same conversation in the API workbench (including the system prompt), with 2048 max output tokens and 4096 max output tokens respectively.

Here are the responses.

  • 2048 max output length: https://pastebin.com/3x9HWHnu

  • 4096 max output length: https://pastebin.com/E8n8F8ga

Since claude's tokenizer isn't public, I'm relying on OAI's, but it's irrelevant whether they're perfectly accurate counts or not - I'm comparing between the responses. You can get an estimation of the claude token count by adding 20%.

Note: I am comparing just the code blocks, since they make up the VAST majority of the length.

  • Web UI response: 1626 OAI tokens = around 1950 claude tokens

  • API response (2048): 1659 OAI tokens = around 1990 claude tokens

  • API response (4096): 3263 OAI tokens = around 3910 claude tokens

I would call this irrefutable evidence that the webUI is limited to 2048 output tokens, now (1600 OAI tokens is likely roughly 2000 claude 3 tokens).

I have been sent (and have found on my account) examples of old responses that were obviously 4096 tokens in length, meaning this is a new change.

I have seen reports of people being able to get responses over 2048 tokens, which makes me think this is A/B testing.

This means that, if you're working with a long block of code, your cap is effectively HALVED, as you need to ask claude to continue twice as often.

This is absolutely unacceptable. I would understand if this was a limit imposed on free users, but I have Claude Pro.

EDIT: I am almost certain this is an A/B test, now. u/Incenerer posted a comment down below with instructions on how to check which "testing buckets" you're in.

https://www.reddit.com/r/ClaudeAI/comments/1f4xi6d/the_maximum_output_length_on_claudeai_pro_has/lkoz6y3/

So far, both I and another person that's limited to 2048 output tokens have this gate set as true:

{
    "gate": "segment:pro_token_offenders_2024-08-26_part_2_of_3",
    "gateValue": "true",
    "ruleID": "id_list"
}

Please test this yourself and report back!

EDIT2: They've since hashed/encrypted the name of the bucket. Look for this instead:

{
	"gate": "segment:inas9yh4296j1g41",
	"gateValue": "false",
	"ruleID": "default"
}

EDIT3: The gates and limit are now gone: https://www.reddit.com/r/ClaudeAI/comments/1f5rwd3/the_halved_output_length_gate_name_has_been/lkysj3d/

This is a good step forward, but doesn't address the main question - why were they implemented in the first place. I think we should still demand an answer. Because it just feels like they're only sorry they got caught.

With effective caching, you can dramatically increase your actual throughput without increasing your rate limits. Monitor your cache hit rate on the Usage page to optimize your caching strategy. OTPM rate limits are estimated based on max_tokens at the beginning of each request, and the estimate is adjusted at the end of the request to reflect the actual number of output tokens used.
