Benchmarking solves one problem. Deployment is a different one entirely.
Knowing how your model performs is not the same as shipping it.
That distinction is at the heart of how Melange and Google AI Edge Portal approach on-device AI differently. Both tools deal with running AI on real devices. Both involve benchmarking on real hardware. But one stops at the data. The other takes you all the way to production.
The problem both tools are trying to solve
Getting an AI model to run well on a mobile device is harder than it sounds.
A model that performs well in a cloud environment does not automatically perform well on a Snapdragon 8 Elite or an Apple A18. Different chipsets have different NPU architectures. Different runtimes handle quantization differently. A model running FP32 on CPU might be 40x slower than the same model running INT8 on NPU. Without real device testing, you are guessing.
Both Melange and Google AI Edge Portal exist because this problem is real and widespread. Where they diverge is in what they do after you have the answer.
What Google AI Edge Portal is
Google AI Edge Portal is a benchmarking tool in private preview, built on Google Cloud. You upload a .tflite model, configure your runtime settings including accelerator type and CPU thread count, select a device scope from a pool of real Android devices, and run a benchmark job. When it completes, you get detailed performance data broken down by device, including latency, memory usage, and device metadata covering processor, RAM, API level and release year.
The depth of the data is genuine. Results are filterable. You can customize which of the 17 available fields appear in your table, including GPU make, GPU model and GPU version. A scatter plot visualization plots steady inference against peak memory across Low, Mid and High tier devices, giving you an immediate read on performance distribution that a table cannot convey. Gemini is integrated into the search bar so you can get contextual help without leaving the page.
For an ML team at a large organization that lives inside Google Cloud and needs rigorous benchmark data to make model architecture decisions, this is useful infrastructure.
But the workflow ends there.
Google AI Edge Portal generates no deployment code. It produces no SDK. Once you have your benchmark results, the path from those numbers to a working app is entirely your own to build. You will need to go back to LiteRT documentation, write your own integration, handle runtime selection manually, and figure out quantization yourself. The portal told you what the best configuration is. It did not help you use it.
What Melange is
Melange is a full end-to-end platform for on-device AI deployment. The workflow is three steps: Select, Benchmark, Deploy. Each step flows into the next without leaving the platform, without setting up cloud infrastructure, and without writing low-level hardware code.
You start by picking a model. If you already know what you need, search the public library which includes Gemma, Whisper, LFM2.5, Qwen, YOLO and more, or upload your own. If you are earlier in the process, describe what you are building in the chat interface and Melange recommends the right model for your use case. This matters for developers who are not ML researchers. You should not need to already know that LFM2.5 350M exists to start building a voice assistant.
Once you have a model, Melange benchmarks it automatically across 100+ combinations of runtime, quantization, processor and chipset on real devices. The results come in two layers. The Model Summary gives you a fast read on latency, NPU performance gain, memory and overall deployability score. The Advanced Report gives you the full breakdown across NPU, GPU and CPU, with FP32, FP16 and INT8 precision variants, across Qualcomm, MediaTek, Exynos and Apple chipsets. Here is what that looks like for a real model tested on real devices:
Then you deploy. Select your optimization mode, speed, accuracy or auto. Select your language, Java, Kotlin or Python. Melange generates the SDK code. You copy it, paste it into your app, and ship. No separate runtime setup. No reading through documentation to figure out the next step. The path from benchmark to production is the same platform, the same session, the same workflow.
One developer. Hours, not weeks.
Where they differ
The difference is not benchmarking quality. It is what happens after.
Google AI Edge Portal answers one question well: how does my model perform across devices? Melange answers a bigger question: how do I get my model running on real devices and into production, fast?
On model discovery: Melange has a public library and a chat interface. Google AI Edge Portal assumes you already have a .tflite file.
On platform coverage: Melange covers Android and iOS across Qualcomm, MediaTek, Exynos and Apple chipsets. Google AI Edge Portal is Android only.
On setup: Melange requires a sign-up. Google AI Edge Portal requires a Google Cloud project, Cloud Shell API enablement, and a GCS bucket before you run your first test.
On deployment: Melange generates production-ready SDK code in your chosen language with one click. Google AI Edge Portal generates nothing. The developer builds the deployment path manually.
On optimization: Melange automatically selects the best runtime and quantization combination per device across 100+ configurations. Google AI Edge Portal surfaces the data and leaves the decision to you.
Where Melange goes further
Benchmarking tells you how a model performs. It does not tell you how to ship it.
When a team used Melange at LA Hacks 2026 to benchmark their custom neural network, they had results across Apple, Samsung, Google and Xiaomi devices in 16 minutes. Running on the NPU via Melange, their model delivered a 26x performance improvement compared to CPU deployment, at sub-millisecond latency with zero cloud dependency. They went from benchmark to shipped demo in a 36-hour hackathon. That is not a research exercise. That is a deployment platform doing its job.
This is the gap. Knowing that your model runs at 2.8ms steady inference on a Pixel 9 is useful information. But a developer building a real app needs to go from that number to working code in their project. Melange is the step between benchmark data and production code that Google AI Edge Portal does not have.
Melange also covers both platforms. If you are building for Android and iOS, you do not need two separate tools, two separate benchmarking pipelines, or two separate deployment workflows. One platform, both platforms, same three steps.
And for developers who are not coming in with a pre-trained .tflite file ready to go, the model library and chat interface change where the workflow starts. You begin with a problem, not a file.
Two tools, two jobs
Google AI Edge Portal is built for teams doing model research inside Google Cloud. It gives you deep benchmark data to inform architecture decisions, and it does that well.
Melange is built for developers who need to ship. Select the right model, understand how it performs on the actual target hardware, and get it into production without building your own optimization pipeline from scratch.
On-device AI deployment has historically meant weeks of fragmented work. Different runtimes, different chipset SDKs, manual quantization calls, no unified path from model to device. The hardware sitting in people's pockets today is more capable than most developers are using it for. The gap has never been the hardware. It has been the tooling.
Melange was built to close that gap.
