Automation has accelerated agent workflows and now needs broader connections for enterprise data
In the current function calling, if Fireworks AI could be added as part of our RAG system not only with the function calling we are using now but also with a variety of other connections, then an even better situation would be possible. Fireworks is based on tool calling, so it needs to add more different kinds of connections to enable faster data retention and optimization. Although multiple optimal optimization or measurement methodologies for using LLMs are being discussed, when using them inside enterprises, the main thing is actually measuring work handling capability or work processing speed. Based on that, and also through what might be called interviews with business-side staff, we measured the speed improvements in a somewhat indirect manner.

Enabled creation of innovative projects through developer-friendly features
The aspect I like most about PyTorch is that it is really developer-friendly. Developers can constantly create new things, and everyone around the world can use it for free because it's an open-source product. What I personally like is that PyTorch has enabled users to use Apple's M1 chip natively for GPU users. Unlike other libraries using CUDA, PyTorch utilizes Metal Performance Shaders (MPS) to enable GPU usage on M1 chips.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"After introducing Fireworks AI's high-speed inference engine, I found that communication speed between agents was about twice as fast as before."
"Since using Fireworks AI, being part of their startup program has resulted in significant cost savings and has helped accelerate our development timeline."
"Fireworks AI has positively impacted my organization by helping my productivity go up."
"Based on my exploration so far, I find that Fireworks AI offers a platform where I can run and build my own AI models, which I consider to be the best feature."
"Fireworks AI has helped our organization by enabling us to create a platform for artists to sell their art styles."
"Fireworks AI has a solid API and is quite easy to interact with."
"Fireworks AI has positively impacted our organization by making our AI features feel more production-ready instead of experimental."
"Fireworks AI has impacted us positively as it helps in offering us access to the open-source models by advancing fine-tuning options, a massive library where we can get information from the database that we can use in line with our company policy."
"I like that PyTorch actually follows the pythonic way, and I feel that it's quite easy. It's easy to find compared to others who require us to type a long paragraph of code."
"Its interface is the most valuable, and the ability to have an interface to train machine learning models and construct them with the high-level interface, without excess busting and reconstructing the same technical elements, is very useful."
"It's been pretty scalable in terms of using multiple GPUs."
"For me, the product's initial setup phase is easy...For beginners, it is fairly easy to learn."
"PyTorch allows me to build my projects from scratch."
"yTorch is gaining credibility in the research space, it's becoming easier to find examples of papers that use PyTorch. This is an advantage for someone who uses PyTorch primarily."
"We use PyTorch libraries, which are working well. It's very easy."
"The product's initial setup phase is easy."
 

Cons

"Fireworks AI can be improved by addressing that costs can rise at scale."
"Based on my exploration so far, I find that it is too early to judge any improvements or negative aspects of Fireworks AI, as I am still in the exploration phase."
"The customer support for Fireworks AI is average."
"When using the API, it does not return information about the charges for image generation, which would be useful for our solution."
"Receiving a $40,000 bill out of nowhere, for usage I never knowingly incurred and which my own dashboard does not reflect, has been an extremely stressful experience."
"The only challenge is that Fireworks AI is not a ready-made business application; you have to customize it to suit your organization's taste, and it lacks a user-friendly dashboard, making it very difficult to grasp."
"In the current function calling of Fireworks AI, I am using it as one part of my RAG system. If Fireworks AI could be enhanced not only with the function calling I currently use, but also by adding a variety of other connections, then I think it would lead to an even better situation."
"One of the things that could improve Fireworks AI is the cost, which I think is really expensive."
"The analyzing and latency of compiling could be improved to provide enhanced results."
"I've had issues with stability when I use a lot of data and try out different combinations of modeling techniques."
"On the production side of things, having more frameworks would be helpful."
"I do not have any complaints."
"The product has certain shortcomings in the automation of machine learning."
"PyTorch could make certain things more obvious. Even though it does make things like defining loss functions and calculating gradients in backward propagation clear, these concepts may confuse beginners. We find that it's kind of problematic. Despite having methods called on loss functions during backward passes, the oral documentation for beginners is quite complex."
"I would like a model to be available. I think Google recently released a new version of EfficientNet. It's a really good classifier, and a PyTorch implementation would be nice."
"We faced an issue with PyTorch due to version incompatibility. PyTorch has no latest version after v12.3."

Questions from the Community

What is your experience regarding pricing and costs for Fireworks AI?
Be extremely cautious. Although it is marketed as 'Pay-As-You-Go,' there are no spending caps, no threshold alerts, and no notifications. We received a sudden $40,000 charge via AWS Marketplace, wh...
What needs improvement with Fireworks AI?
Billing transparency and safeguards are urgently needed. A product sold as 'pay-as-you-go' should never produce a surprise $40,000 charge with no spending cap, no real-time threshold alert, and no ...
What is your experience regarding pricing and costs for PyTorch?
I haven't gone for a paid plan yet. I've just been using the free trial or open-source version.
What needs improvement with PyTorch?
There are a few areas for improvement. The biggest one for me is version and dependency management, as I have to ensure my Torch, TorchAudio, and CUDA versions are all aligned. If one is off, thing...
What is your primary use case for PyTorch?
I have been using PyTorch for the last three years, mostly through my thesis work and model deployment projects. I use PyTorch for pretty much everything in my deep learning work, specifically to b...
