What is it?

Llama 3.2 Mobile is Meta’s purpose-built family of small on-device language models, released in September 2024. Meta shipped the 1 B and 3 B variants as text-only models — distinct from the same generation’s 11 B and 90 B vision models, which target larger devices. The mobile pair was created using structured pruning of larger Llama 3.1 models combined with knowledge distillation: logits from the Llama 3.1 8 B and 70 B models were used as token-level targets during pretraining, retaining surprising amounts of reasoning capability for their size. As of mid-2026, these remain Meta’s primary mobile offering — there is no direct Llama 4 successor in this size class yet.

Core specs at a glance

What devices can run it?

The 3 B variant runs comfortably on Pixel 8 and newer, iPhone 15 Pro and newer, and Snapdragon 8 Gen 3+ Android phones. Meta partnered with Qualcomm and MediaTek for day-one launch optimization, and the model is heavily tuned for ARM CPUs via Grouped-Query Attention. The 1 B variant relaxes those requirements significantly — it runs on phones from 2022 onwards with at least 4 GB of RAM. Both versions are deployable via llama.cpp, MLC, or PyTorch ExecuTorch.

Strengths and limitations

Strengths. Massive 128 K context — same as Gemma 4 E2B, ahead of most other on-device peers. Strong reasoning for its parameter count thanks to distillation from the Llama 3.1 8 B and 70 B teachers. Mature ecosystem: llama.cpp, LM Studio, Ollama, MLC, and dozens of fine-tunes. Day-one mobile chip optimization. Open weights, easy to fine-tune.

Limitations. Text-only — no images, no audio. The Llama Community License has a 700 M MAU clause that complicates contracts with mega-services. No clear successor in the Llama 4 generation. Multilingual quality varies; English and major European languages are strongest.

When to choose it (and when not to)

Choose Llama 3.2 Mobile if: your workload is text-only (chat, summarization, classification, RAG); you want the broadest open-source ecosystem and tooling; you need a fully open mobile model with 128 K context; your target devices have at least 6 GB of RAM (3 B) or 4 GB (1 B).

Skip it if: your workload includes images or audio (Gemma 4, Phi-4-multimodal, or MiniCPM-V are better); you operate a service with 700 M+ MAU and need permissive licensing without negotiation (Apache 2.0 alternatives like Gemma 4, Qwen 3.5, or Mistral fit better); you want the absolute smallest text model (DeepSeek-R1 Distill 1.5 B is a finer-grained option).

How it compares to similar on-device models

The closest peers are Gemma 4 E2B (smaller, multimodal, Apache 2.0) and Ministral 3B (similar size, also multimodal, Apache 2.0). Llama 3.2 wins on ecosystem maturity and 128 K context but loses on modality and license simplicity. For a side-by-side, see the leaderboard.

In a real Cove app

Cove Voice uses Gemma 4 today for summarizing voice notes — a workload that fits Llama 3.2’s text-only profile equally well. We chose Gemma 4 because we need the same model to handle photo Q&A in Cove Photo, and Llama 3.2 Mobile does not see images. If a future Cove app were text-only (say, a journaling assistant), Llama 3.2 3B would be a strong alternative — particularly for users who want full ecosystem tooling and Hugging Face fine-tunes.

FAQ

Why is Llama 3.2 Mobile text-only?

Meta split Llama 3.2 into two tracks: 1B and 3B for mobile/edge are pure text, while 11B and 90B handle vision. The mobile sizes traded multimodality for the smaller footprint and 128K context that ships well on phones — vision needs more memory and Meta judged it a worse trade-off for edge.

What devices can run it?

Pixel 8 and newer, iPhone 15 Pro and newer, Snapdragon 8 Gen 3+ Android phones. Meta optimized day-one for Qualcomm and MediaTek SoCs and ARM CPUs. The 3B version needs roughly 2 GB of storage at Q4 quantization plus 4-6 GB of RAM headroom for context.

Is Llama 3.2 free for commercial use?

Mostly. The Llama Community License permits commercial use but with a clause: services with more than 700 million monthly active users must request a separate license from Meta. For startups and indie apps, this is effectively Apache 2.0 minus consumer-app megaservices.

Is there a Llama 4 mobile version yet?

Not as of mid-2026. The Llama 4 family (Scout, Maverick) released in April 2025 targets datacenter MoE workloads. Llama 3.2 1B/3B remain the primary Meta on-device offering. Meta is rumored to ship a new mobile-tier model in Llama 5 with screen-aware agentic features.

How does it compare to Gemma 4 or Qwen 3.5?

Llama 3.2 3B is text-only, while Gemma 4 E2B and Qwen 3.5 2B both support multimodal text+vision. Llama wins on long-context (128K shared with Gemma; Qwen pulls ahead at 262K). Pick Llama if you need Meta ecosystem (LangChain, llama.cpp tooling); pick Gemma/Qwen if you need vision.
