Pricing Update: Token Based Billing for Fine Tuning Training 🎉
We’re updating our billing for fine tuning with the Azure OpenAI Service to bill based on the number of tokens in your training file – instead of the total elapsed training time.
Model
Previous Price
New Price
Babbage-002
$34 / hour
$0.0004/1K tokens
Davinci-002
$40 / hour
$0.006/1K tokens
GPT-35-Turbo (4k)
$45 / hour
$0.008/1K tokens
GPT-35-Turbo (16K)
$68 / hour
$0.008/1K tokens
GPT-4
$102 / hour
$0.080/1K tokens
Why make this change? If you’ve fine-tuned before – or thought about it and decided against it – you may have struggled to estimate the cost. While it’s easy to guess relative time (longer files, more epochs take longer) there’s was no easy way to estimate an exact time. Now, it’s simple: count the number of tokens in your file, multiply that by the per token price, and the number of epochs and you’ve got a decent estimate for the overall costs. Note: the raw token count for your file may be higher than the actual token counts you’ll be charged for, so this is an estimate, not the actual value you will be billed.
In practice, this change will be a substantial discount for some training runs. For example, I recently fine-tuned GPT-35-Turbo 0613 with a small (45k token) dataset over 3 epochs. With hourly billing, this job took 1.5 hours and cost me $67.50 — but with the switch to token based billing, it costs just $1.08! The price difference isn’t quite as big for large files: I trained GPT-35-Turbo 0125 with a large file (2.2M tokens) for one epoch, taking 1 hour and 15 minutes, at a price of $85 when billed hourly – or ~$18 when based on tokens.
Not sure how to count up the tokens in your file? Tools like OpenAI’s tiktoken library make it super simple to specify your model and write a short script to count tokens in your training data. Alternatively, many IDEs support plug-ins to provide token counts right in your status bar.
With these updates, experimenting with fine tuning should be easier than ever: you can easily estimate costs, and with lower and more transparent pricing you can train more models. More training runs allows you to assess the impact of different parameter combinations, data sets and more – and hopefully, create the best custom models for your use case.

Add titles over rows in subplots
Hi,
I have a figure with 8 subplots, arranged in two rows. I need to generate an automated code adding a centered title above each row, but fail to do so.
A sample code to illustrate the configuration (I also have annotations):
clf;
m = 2;
n = 4;
p = 1;
for i = 1:m*n
s(i) = subplot(m,n,p);
ant(i) = annotation(‘textbox’,s(i).Position,’String’,[num2str(i)+")"],…
‘linestyle’, ‘none’,’Fontsize’,14,’FontWeight’,’bold’);
p = p + 1;
end
I want to place the titles without explictly give coordinates, i.e. something like titlehandle.position=[1 2 3 4] is not good, because I sometime use different computers/monitors/OS and the output is not consistent.
Thanks!Hi,

Conductive Heat Transfer of Regenerator Block in Gamma Stirling Engine Model
The conductive heat transfer block is set to planar, when i try to change it to cylndrical for more realistic model as the regenerator is in fact cylindrical.
My inputs are as follows:
Inner Diameter = geometry.displacer_piston.radius
Outer Diameter = geometry.displacer_piston.radius + geometry.displacer_piston.glass_thickness
Length = regenerator.geometry.length
Conductivity (K) = regenerator.conductionHeater.k
For both of the conductive blocks, when i do that the engine simply fails to operate.
I used temperature sensors and in original model the temperature between heater and ambient are about 1550 but when i do the cylindrical modification it starts at that difference then decrease to zero as time move on

FSLogix Antivirus Exclusions with Standard Microsoft Image
I’m using one of the standard Microsoft images for my Azure AVD setup. The multi-session image is Windows 11 Enterprise with O365 and FSLogix pre-installed. I have setup the necessary GPO for FSLogix and all is working well. Can I assume that Microsoft already applied the necessary antivirus exclusions for FSLogix with Defender?

MS Teams Tab sending chats?
I noticed some tabs have a chat tab that corresponds to a chat in the messages tab on the teams client. I’m wondering how you can do that all in one because the docs seem to specify messaging capabilities is a chatbot feature.

Where is the search bar on the Matlab File Exchange website?
This is more of a recommendation to the MathWorks website developers rather than a quesiton.
I don’t use File Exchange (FEX) often, but when I do, I typically access it through the browser rather than the AddOn button in Matlab. Recently, I noticed that the search bar is missing from FEX, making it impossible to find anything. Upon closer inspection, and five minutes later, I eventually realized that the search option a tiny, barely visible, icon tucked away in the corner of the browser.
To the MathWorks developers responsible for this significant usablity change: why would you hide such a fundamental feature on FEX, which is such a tremendous resource for Matlab users? This change makes it much harder for the users (espicailly those new to Matlab and unfamiliar with FEX) to find what they need and could potentially discourage some from using Matlab.This is more of a recommendation to the MathWorks website developers rather than a quesiton.

Dell laptop runs OOBE several months after being registered and used
We have a Dell Vostro laptop that has started to bring up the Autopilot oobe after login and connected to Wi-Fi, this is several months after first configuration and monitoring with Intune.
it started when the end user visited a colleague. It initially stuck on the ESP screen with no access to the internet, we used the accessibility button to connect to local Wi-Fi. We rebooted via a hard power reset and it ended up at the final section on the ESP page after the user used her pin to login, also same after email address to login. It doesn’t complete the OOBE process and let her get to her desktop. Remotely Intune EndPoint manager can monitor and restart the system.
Has anyone had this?
Intune Support have collected logs and compared with another Autopilot device and gives Intune a clean bill of health!
User is couriering me the laptop as Intune Support feel it is either a Windows issue or a hardware one.
Suggestions welcome
Paul

Questions on Sync and what should I do with one drive after a re-install?
My WIN 11 home laptop comes with Office 365 and OneDrive was set up with the default folders (documents, pictures and desktop). I have a local folder on my C drive (c:mydata) which I want to backup to Onedrive. I copied c:mydata to my OneDrive-personal. Under Windows Explorer, I can see
OneDrive -personal
– Documents
-Pictures
-Desktop
-mydata
and on local, OS(C:)
-mydata
Most of the time, I updated the files under C:mydata. This way, if I lose my network connection, I can continue to work with the updates on C:mydata. Whatever update I did showed up on OneDrive-personalmydata sometime later. I am a casual user. I did not check the delay and did not think much about it. From my experience, I know the updates showed up at least a few hours later. However, I don’t believe this is right because if I use OneDrive as my backup my local update should go to OneDrive immediately otherwise any update will be lost before the sync happens.
My questions are
1. Am I doing things wrong all along? Should I update OneDrive -personalmydat first and wait for the sync to update my local C:mydata?
2. If I have to work on C:mydata because there is no network connection, how can I force a sync to OneDrive as soon as the network is back?
Last week, I got BSOD on my laptop. I had to recover with a re-install. I picked the keep file and data option. After the re-install, I can see
OneDrive -personal
– Documents
-Pictures
-Desktop
-mydata
But I am not sure how current is mydata? I should only be up to the point of the last Sync. Is there anyway to tell when did the last sync happened?
Since I picked save file and data during recovery re-insatll, is there anything I need to do to OneDrive setup after the re-install?
