OpenAI Cost Monitoring
Hi HN, My name is Ben Schaechter and I’m Co-Founder and CEO of https://vantage.sh - a cloud cost visibility and optimization platform. We just added support for monitoring OpenAI costs and usage to Vantage and I wanted to share a demo we put together with HN as I thought people might find it interesting: https://www.youtube.com/watch?v=CzAOU1-uMrM In early April we started getting requests from customers to add OpenAI cost support specifically as it was a bit opaque as to what exactly was driving costs.

In plain words
Vantage has added OpenAI cost monitoring to its cloud cost visibility platform, allowing users to track spending and usage across OpenAI services. The feature integrates with OpenAI's API to break down costs by organization and operation, addressing customer requests for clearer visibility into what drives OpenAI expenses. This beta integration uses an undocumented OpenAI API and is designed for teams managing cloud infrastructure costs.

Hi HN, My name is Ben Schaechter and I’m Co-Founder and CEO of https://vantage.sh - a cloud cost visibility and optimization platform. We just added support for monitoring OpenAI costs and usage to Vantage and I wanted to share a demo we put together with HN as I thought people might find it interesting: https://www.youtube.com/watch?v=CzAOU1-uMrM In early April we started getting requests from customers to add OpenAI cost support specifically as it was a bit opaque as to what exactly was driving costs. The way this works is that it uses an undocumented API available from OpenAI - I asked ChatGPT how to get this info and this is what it recommended. The OpenAI team said this was fine to use but is subject to change in the future which is why this feature is in beta right now. This new integration uses an OpenAI API key to report on costs by organization, operation (i.e “Completion”), and model (i.e. “GPT-4”). It also allows you to forecast your OpenAI costs and set up billing alerts in Slack if costs begin to increase rapidly. I’d love to know what people think on this and if you have any feedback good or bad for us to improve this moving forward.

- AMAn MCP server for understanding AWS costs2025 · ▲119
Hey all - I work at Vantage, a FinOps platform. I know AI is peak hype right now. But it has definitely changed some of our dev workflows already. So we wanted to find a way to let our customers experiment with how they can use AI to make their cloud cost management work more productive. The MCP Server acts as a connector between LLMs (right now only Claude, Cursor support it but ChatGPT and Google Gemini coming soon) and your cost and usage data on Vantage which supports 20+ cloud infra providers including AWS, Datadog, Mongo, etc. (You have to have a Vantage account to use it since it's…
- SASee AWS Costs for Each Resource2022 · ▲8
Link: https://www.vantage.sh/features/per-resource-costs Hi HN, I'm Co-Founder and CEO of Vantage and we just made "Per-Resource Costs" available to everyone, including users in our free tier. Vantage will now show you the cost of each individual AWS resource (EC2 instance, RDS instance, S3 Bucket, SNS Topic, Lambda Function, etc). You can drill down into each resource to see subcategory costs so imagine seeing specific egress costs being tied to a specific Cloudfront distribution or EC2 instance. This works by Vantage ingesting and processing Cost and Usage Reports from…

Hi HN, https://www.youtube.com/watch?v=MN7RNVo9nc4 (The text below is based upon the linked video above) I'm Co-Founder & CEO of Vantage: a cloud cost observability platform. Our team put together a quick video showing a new feature we launched that I think this community may be interested in: Network Flow Reports. This gives you the ability to see flows normalized by cost instead of usage for AWS resources. Knowing that AWS has different rates depending on the source and destination of network traffic, we did the work of ingesting VPC Flow Logs and cross-referencing with the…

I have been working on making WebRTC + Embedded Devices easier for a few years. This is a hackathon project that pulled some of that together. I hope others build on it/it inspires them to play with hardware. I worked on it with two other people and I had a lot of fun with some of the ideas that came out of it. * Extendable/hackable - I tried to keep the code as simple as possible so others can fork/modify easily. * Communicate with light. With function calling it changes the light bulb, so it can match your mood or feelings. * Populate info from clients you control. I wanted…

Hi HN, Today we’re launching GPT-4 answers on Phind.com, a developer-focused search engine that uses generative AI to browse the web and answer technical questions, complete with code examples and detailed explanations. Unlike vanilla GPT-4, Phind feeds in relevant websites and technical documentation, reducing the model’s hallucination and keeping it up-to-date. To use it, simply enable the “Expert” toggle before doing a search. GPT-4 is making a night-and-day difference in terms of answer quality. For a question like “How can I RLHF a LLaMa model”, Phind in Expert mode delivers a…
