The practical levers are to use a smaller task-appropriate model, apply quantization if the runtime supports it, limit context and other memory-heavy features, and use an acceleration path designed for the device. A model’s download size is not its full RAM requirement: the runtime, context or KV cache, input buffers, and the rest of the app need memory too.
There is no single RAM requirement for “AI”
Memory needs depend on the model, runtime, context length, accelerator, and task. A small classifier, an image model, and a text-generating language model do not have interchangeable requirements. The reviewed platform documentation does not establish a universal minimum amount of RAM for running AI.

For one specific workflow, NVIDIA’s TensorRT-Edge-LLM installation guide sets a minimum of available device memory equal to model size plus 2 GB before inference. That is a prerequisite for that runtime, not a rule for phones, computers, or AI workloads generally; NVIDIA notes that KV cache and other components can push the requirement higher.

Pick the symptom - the matching free tool is one click away.
Choose a model that fits the job
Start with the task and the quality it needs. A task-specific model may use less memory than a general-purpose language model. For text generation, look for the smallest supported model that produces acceptable results on representative prompts.

Google’s on-device LLM Inference documentation lists Gemma 3n E2B and E4B, which use selective parameter activation and are described as operating at effective sizes of 2B and 4B parameters, as well as Gemma 3 1B and Gemma-2 2B. These are model options, not guarantees that a particular phone or computer can run them comfortably. Google’s API supports on-device execution across web, Android, and iOS; the compatible model and runtime still need to match the target platform. Google AI Edge LLM Inference.
Budget for the whole inference workload
Do not estimate from installed RAM or the model download alone. The inference process shares memory with the operating system and application, and it may need space for runtime components, input and output buffers, context/KV cache, and other active tasks. Multimodal components, larger batches, or longer sequences can increase the requirement.

For Google’s Gemma 3 1B setup, the documentation says the configured maxTokens must match the model’s built-in context size. On the web, model initialization can block the current thread, so Google recommends using a worker thread when possible. Those are implementation details for that API and model rather than universal settings.
Use quantization carefully
Quantization stores model values at lower precision. Google documents potential reductions in model storage, runtime RAM, computation, latency, and power, but also warns that optimization can change accuracy. The size of any change depends on the model and configuration; no universal accuracy penalty is established. Google AI Edge model optimization documentation.

Google describes several post-training approaches, each with different trade-offs:
- Weight-only quantization: quantizes weights and may preserve accuracy better in the documented recipes.
- Dynamic quantization: generally recommended in Google’s guidance for CPU or GPU deployment.
- Static quantization: generally recommended for NPU deployment and requires calibration data.
These are general characteristics, not a guarantee for every model or device. If a low-bit model performs poorly on your task, selective or mixed-precision quantization can keep more sensitive operations at higher precision. Compare versions with the same representative inputs and record peak memory, response time, and task quality.

Match the runtime to the hardware
On-device AI depends on software and hardware compatibility; a model or accelerator path that works in one ecosystem may not work in another. Choose a supported runtime and model format for the device you intend to use.

- Apple platforms: Apple’s Core AI documentation covers loading and running models on Apple silicon, including optimization options such as quantization and palettization. Apple Core ML documentation.
- Embedded systems: Arm describes deploying optimized LiteRT models on Cortex-M processors, with Helium vector processing and Ethos-U NPUs among the supported hardware approaches. Arm Developer edge AI guidance.
- Supported NVIDIA systems: TensorRT-Edge-LLM has its own platform, version, and memory prerequisites; check these before choosing it. NVIDIA TensorRT-Edge-LLM documentation.

Reduce avoidable overhead, then measure
Closing unnecessary applications or using a leaner system configuration can leave more memory for inference, when the device and deployment allow it. NVIDIA’s Jetson Orin Nano 8 GB case study illustrates the potential on one specific system: NVIDIA reports about 7.6 GB usable after firmware and kernel reservations. In that setup, running headless reduced the reported OS footprint from 1.8 GB to 1.1 GB, while quantizing a vision-language model changed its reported footprint from 6.6 GB at FP16 to 2.2 GB at Q4_K_M. NVIDIA reports that the tuned pipeline used 4.5 GB of the 7.6 GB available. These figures describe NVIDIA’s hardware, model, and software configuration; they are not general benchmarks or expected savings on another device. NVIDIA Developer case study.
For a fair comparison of model or runtime options, run the same workload on the target device and track:
- Peak memory: include weights, runtime, context/KV cache, buffers, and other active applications.
- Task quality: check correctness or usefulness on representative inputs after compression.
- Latency and throughput: measure time to first output and the rate of generation or processing.
- Power and thermal behavior: relevant for battery-powered or sustained workloads.
- Compatibility and maintenance: verify device, runtime, model format, accelerator, SDK, and license requirements.
Decide whether inference must stay on-device
On-device inference can avoid a server dependency for the inference step, but it does not automatically determine how an app handles data elsewhere. A cloud fallback is a product choice rather than a way to make a model fit into local memory. Compare connectivity, privacy, cost, and reliability requirements separately; the platform sources cited here do not quantify those trade-offs against cloud inference.
