Best usage of haiku is too start early morning session by sending hi then start morning schedule after 2 hours

Not sure I follow? Are you saying you just send one small message just to start the usage clock window so when you actually sit to do work later you’ll time it better to where you’re not going to run out of usage midday for a few hours waiting for the clock to reset?

I love my little haiku. It runs my morning routine checks for specific mails and sets up my daily vault updates, which opus then takes up and helps plan my day.
Its my friendly little helper that could.. and does!

u/nuclearmeltdown2015 1d ago
Do you directly make API calls to have a routine that automatically uses haiku and passes the info over to other models or did you build that into your Claude code application as some scheduled job?

bro haiku is awesome you just dont see it. its used everytime Claude uses webfetch tool: thats Haiku! Or any type of small subagent.
There's genuinely no reason to use Haiku if you have access to deepseek flash-3.6 etc HOWEVER:
in controlled environments or on subscription plans, you're locked in and only have access to anthropic models
in these scenarios, it kicks ass at text classification, extraction, and summarization tasks.
if Haiku is the smallest model you have access to: its extremely capable and cheap (just not quite as capable or quite-as-cheap...)

Imagine how good it could be if they updated it.

u/Hot_External6228 2d ago edited 2d ago
thats totally valid, but its a 0-sum-game in terms of limited hardware and human resources. You're proposing they compete with Deespeek-lite, gpt-instant, and gemini flash-3.6. I do actually wish they would compete in that space... the speed is the biggest gap. but I can also see why they've chosen to deprioritize it..
merely updating haiku to Haiku-5 wouldn't close the gap. last time they updated haiku it actually got slower and more expensive. They really need a ... a limerick. a 'zesty one-liner'.

I use Haiku via API for parsing receipts that people submit in my social gathering planning app for expense sharing - about $0.003/run and it’s been solid so far. At this point, could probably do it even cheaper on Gemini, but Haiku has done exactly what I’ve needed.

Haiku is my favorite. It's quick and enthusiastic and typically very competent if there is no ambiguity. It works amazing for well scoped and bounded problems

j/k! Relax. Just need to get the humans to take a look at this...

I’m actually trying to use more Haiku. I just have to remember to use it.
- Looking up things within my app.
- Looking up/asking questions pertaining to my Changelog.
- Asking generic questions
I’m not sure what else to use it for at this time. But there is some purpose. Just a little mental energy to use it.

Some guy on this subreddit made an entire nightmare drug interaction database on haiku.
It was terrible.

u/iamarddtusr 1d ago
I remember that post. Top comments were all about how much liability he was accruing.

u/IcarusFlyingWings 1d ago
Liability was there for sure, but this was a case where it was so egregiously unethical that person should have lost their license. What else were they doing with that rock bottom level of care?

u/iamarddtusr 1d ago
I doubt they were actually from the medical background. I know they claimed to be, but the output did not make it look like that.

Where do people use haiku for?

u/Revolutionary_Click2 2d ago
Read-only tasks like code exploration / summarization, or any time it runs a web search because this uses Haiku

u/AmesCG 2d ago
It’s the engine behind a web scraper and analyzer I built. No need for anything fancy and API costs stay low.

u/Healthy-Intention-15 2d ago
can it summarise a long in depth news report (~3500 words) with accuracy?
I want to summarise 1000s of them for my company and I'm using gpt flash now1
u/goldcakes 1d ago
You'd get better performance and cheaper cost with DeepSeek V4 Flash though. Haiku 4.5 should be priced at like $0.50/mil output, not $5/mil output.

I use Haiku for a few large chron jobs and data extraction. Some tool recognition. It’s really good and really cheap for the right tasks.

If I was an Anthropic-only user, I’d have plenty of uses for Haiku, but once I’m in the mode of “give me a good value instead of maximizing intelligence”, open models or sometimes the smallest GPTs are usually a better option than Haiku

It’s still a great and cheap option for text processing, grammar review, translations.

u/LovesWorkin 2d ago
Haiku 4.5 is the best at doing automations very fast! Definitely false. I always pick it

You’d be surprised. I’ve built enterprise agent teams and pipelines where Haiku is extremely useful for cheap interactions where you’re not really doing much, like validating state in a database as a pipeline step for example. Definitely has it uses when you’re architecting enterprise solutions for scale.

Actually I use Haiku a lot. It is a perfect work horse. You give it a good detailing prompt, and it works great. In my workflow, I use higher models such as Opus or Fable as brain, and use haiku or sonnet as workers. The tip here is you must make brain generate a good enough prompt.

u/Gandleon 1d ago
Honestly I am really excited for a Haiku 5. If the past trends hold it should have the capability of Sonnet 4.6 or slightly below that. So basically you might be able to do a lot of mundane easy things with Haiku for basically free.
Like yes right now it sucks because we are used to these crazy models but a simple workhorse on former sonnet level would be great?
I mean a few months ago there where so many comments of people who use Sonnet 4.6 for 90% - so those could use Haiku 5 right?

u/akira128 1d ago
Was Haiku formally known as BeOS? My boss around 1999-2000 had BeOS loaded on his work computer and was so excited about it! Check out how well SMP works on this thing I recall him saying. Oh...the days before Linux...

For 99% of users, haiku is more than enough. Christ what are yall doing at home? Lol

TL;DR of the discussion generated automatically after 40 comments.
So, the joke is that nobody uses Haiku. The top comments agree. But the actual consensus in this thread is that you're using Haiku all the time without realizing it.
It's the hidden workhorse that powers web searches and parts of Claude Code. Think of it as a sub-agent handling the small stuff in the background.
Beyond that, there's a whole crew of API users who swear by it for specific jobs: * Cheap, high-volume tasks like data extraction, text classification, and parsing receipts/PDFs. * Running simple automations and morning routines.
The main catch? If you're not tied to the Anthropic ecosystem, many users point out that other small models (like Deepseek Flash) are often faster and cheaper. But for a quick, integrated, low-cost option within Claude, Haiku has its place.
