Rapid experimentation has transformed our AI prototyping and collaboration workflows
There are definitely a few areas where Lightning AI can improve. Overall, we have had a positive impact, but there are definitely a few areas it could enhance. One area is cost visibility and resource management. There are multiple teams running experiments, GPUs, and long-running sessions. It is not always obvious how much compute is being consumed and what the projected costs might be. More granular visibility and alerts would help the team manage usage proactively. Another area is workspace and project organization. As the number of experiments grows, it can become difficult to keep projects, notebooks, data sets, and test environments organized. Better lifecycle management could help achieve this and discoverability would be useful for larger teams. We have also encountered situations where long-running sessions or development environments needed more resilience. While this is not unique to Lightning AI, interruptions during model training and experimentation can be frustrating, especially when working with larger data sets. From an enterprise perspective, I think there is room to strengthen governance and operational control. Features around permissions, auditability, environment standardization, and usage policies become increasingly important as adoption expands across teams. I would particularly appreciate better support for moving successful experiments into production workflows. There could be better cost and resource visibility, stronger project and experiment organization, improved reliability for long-running sessions, stronger governance capabilities, and a smoother journey from experimentation to production. None of these are major blockers for us, but these are areas where the platform could become more valuable as the team and workload scale. A minor annoyance would be stronger project and experiment organization. When more data sets and more projects come into place, it becomes difficult to organize, and keeping them in a standardized way becomes slightly difficult. That is an area I wanted to highlight. There is not much of a pain point. There are a few minor suggestions I would mention, such as observability and experiment tracking at scale. When teams start running many experiments across different models, it becomes increasingly important to have a clear view of what changed and why performance improved or declined. That could be one area. Another area is cross-team discoverability. As AI adoption grows within an organization, valuable experiments and reusable components can be scattered. Better mechanisms for surfacing reusable workflows and templates would be beneficial. I would also appreciate continued investment in LLM and agent development workflows. The AI landscape is evolving rapidly. These suggestions come from the perspective of a team that is using the platform heavily. Most of the core capabilities work well today, which is why the feedback is more about helping the platform scale with a growing AI organization rather than fixing major shortcomings.

Real-time chat has boosted one-to-one messaging and user engagement in my mobile projects
The best features PubNub offers, in my opinion, are one-to-one chat, as I mentioned in my review, and the great SDK documentation which allows for easy integration that does not take much time. Setting up channels, message listeners, tracking user status to determine whether users are online or offline, and ensuring reliable message delivery are all great features. I find myself relying on all three of those features the most because the presence tracking is great, the delivery speed is superb compared to other SDKs, and the user status updates immediately pop up, which is significant. The integration is very easy, so any new developers can easily understand the integration process thanks to the clear documentation. PubNub has positively impacted my organization as I have received numerous reviews and feedback stating that the chat works much faster and cleaner, and everyone appreciates it, saying it feels powerful. After implementing PubNub, I noticed positive outcomes such as client feedback acknowledging that they enjoyed the chat features and found them much faster than in other applications, which I believe is very positive feedback for any organization.

Quotes from Members

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

Pros

"Overall, it has helped us spend less time on infrastructure and operational setup and more time building constantly and evaluating AI solutions that can create value for businesses."
"With the help of Lightning AI, we were able to manage our workflows efficiently, manage our GPU infrastructure effectively, and save a substantial amount of time and actions in those areas."
"Lightning AI changed my workflow compared to what I was doing before by not only saving my time, but also making my training and validations more standardized to try different hyperparameters and logging metrics and tracking points."
"Lightning AI is excellent for setting up GPU servers, Docker, Kubernetes, and ML infrastructure, providing everything in one platform, which is the unique aspect I have noticed."
"PubNub's push notification and chat features stand out because of ease of use and very easy integration within our application."
"The speed and efficiency of PubNub, which helps transfer data in real-time with very low latency, received positive feedback from our customers."
"PubNub has positively impacted my organization as I have received numerous reviews and feedback stating that the chat works much faster and cleaner, and everyone appreciates it, saying it feels powerful."
"PubNub saves development time because we do not have to create a complete chat backend and frontend from scratch, enabling a plug-and-play approach that saves time, effort, and money for the company."
"PubNub has positively impacted my organization by reducing implementation time and developers' work, making it very easy to implement and enabling fast development that has reduced the developers' time by 40-50%."
"If we had implemented all of this on our own, we would have had to hire at least 50 more employees for that, so we are very happy with PubNub and we have saved a lot of time."
 

Cons

"I think I have an idea for improving Lightning AI in the area of debugging distributed training. I know the abstraction is great, but when something can go wrong in multi-GPUs, we could probably have more intuitive diagnostics or clearer error messages that would help us to further reduce iteration time or debugging time."
"When running large workloads or complex projects, Lightning AI can sometimes experience lag or latency issues, and I am not always satisfied with the training results, as I have noticed spikes during training."
"There are definitely a few areas where Lightning AI can improve."
"Most of the time there are some instances at the load peak hours or sometimes payload is missed by the application or SDK at the SDK level."
"Regarding customer support from PubNub, around six years ago, we did not receive good support."
"I gave PubNub a rating of nine out of ten because of the many features discussed, but I deducted one point because the cost increases with scale."
"I believe PubNub can improve in terms of pricing transparency, as I previously mentioned, since that is the only thing I think should be improved because for smaller projects or startups, estimating scaling costs can be challenging."
"Since PubNub is a paid library, it may not be useful for everyone."
"The reliability of PubNub is really good, but occasionally we face issues where users complain about messages or push notifications not being delivered within a short period of time, as it occasionally takes longer, which could be due to outages."
