## TL;DR

Meta replaced Llama 4 with Muse Spark on its AI smart glasses on June 8, 2026. The new model brings native reasoning and multimodal understanding to the hardware, moving the glasses beyond basic object identification toward contextually grounded, hands-free responses. The change affects only Meta's physical smart glasses — not Llama API, Meta AI on mobile, or any other Meta AI service. Glasses start at $299.

## What happened with Meta's smart glasses AI?

Meta swapped out Llama 4 for **Muse Spark** on its AI smart glasses on June 8, 2026. Muse Spark is a reasoning and multimodal model that processes the glasses' camera feed and returns contextually grounded responses hands-free. The switch was reported by [AI Navigate on June 13, 2026](https://ai-navigate-news.com/en/updates/2026-06-13/muse-spark-replaces-llama-4-on-meta-smart-glasses).

## What was wrong with Llama 4 on the glasses?

Llama 4 handled basic scene recognition, but it had a reasoning gap. Complex tasks — reading context, making inferences, giving situationally relevant advice — exposed clear limits. The "see what I see and help me understand it" use case worked at a surface level, but deeper scene understanding was not there.

Here's what we know so far: the switch to Muse Spark was a direct response to those limits, not a routine update.

## What does Muse Spark add to Meta smart glasses?

Muse Spark brings two things Llama 4 lacked: **native reasoning** and **multimodal understanding**. The glasses can now process the camera feed and return answers that reflect what is actually happening in the scene, not just what objects are present.

According to [AI Navigate](https://ai-navigate-news.com/en/updates/2026-06-13/muse-spark-replaces-llama-4-on-meta-smart-glasses), the upgrade moves the glasses from "what is this object" to "given what I'm looking at, what should I do next." Cooking assistance, navigation cues, and guidance in unfamiliar environments are the use cases the source highlights.

## Before vs. after: Llama 4 and Muse Spark compared

| | Llama 4 | Muse Spark |
|---|---|---|
| **Active on glasses** | Up to June 7, 2026 | From June 8, 2026 |
| **Reasoning** | Limited | Native |
| **Multimodal** | No | Yes |
| **Scene understanding** | Basic object ID | Contextual inference |
| **Model type** | Open-weight | Reasoning + multimodal |

## Which Meta products does this change affect?

This change applies **only** to Meta's physical smart glasses hardware. The following are not affected:

- Llama API
- Meta AI on mobile
- Other Meta AI services

If you do not own Meta's smart glasses, nothing changes for you right now.

## What do Meta's AI smart glasses cost?

Meta's AI smart glasses are available starting at **$299**, according to [Glasses.com](https://www.glasses.com/gl-us/meta-glasses). The lineup includes multiple frame styles and lens options, with Transitions® versions starting at $379. The glasses include hands-free access to Meta AI, open-ear audio, and a built-in camera. Prescription lenses are supported.

Builders tracking [Meta AI hardware](/articles/nvidia-rubin-45c-liquid-cooling-zero-water) developments should note that the Muse Spark deployment is a software update, not a new hardware release.

## What should teams tracking Meta's hardware AI roadmap watch next?

AI Navigate recommends watching subsequent software updates as Muse Spark matures on the device. No specific next milestone date is named in the sources. The June 8 deployment is the confirmed event; what follows is not yet reported.

Teams working on [AI-powered wearables](/articles/ai-influencers-brands-fake-social) or multimodal applications may find the Muse Spark architecture relevant as Meta continues to iterate on the glasses platform. For context on how AI model updates affect real-world [hardware performance](/articles/x-outage-cloudflare-june-2026), the June 8 switch is a concrete data point.

## Frequently asked questions

**When did Meta replace Llama 4 with Muse Spark on its smart glasses?**

Meta deployed Muse Spark on its AI smart glasses on June 8, 2026, replacing Llama 4. The change was reported by AI Navigate on June 13, 2026. Llama 4 had been the model running on the glasses up to and including June 7, 2026. The switch is a software update to existing Meta smart glasses hardware, not a new device release.

**What is Muse Spark and what does it do on Meta smart glasses?**

Muse Spark is a reasoning and multimodal AI model deployed on Meta's smart glasses as of June 8, 2026. It processes the glasses' camera feed and returns contextually grounded, hands-free responses. Unlike Llama 4, it has native reasoning built in, allowing the glasses to move beyond basic object identification toward situationally relevant answers based on what the camera sees.

**Does the Muse Spark update affect Meta AI on mobile or the Llama API?**

No. According to AI Navigate, the Muse Spark update applies exclusively to Meta's physical smart glasses hardware. Llama API, Meta AI on mobile, and all other Meta AI services are unaffected by this change. Only users who own Meta's AI smart glasses will experience any difference from the June 8, 2026 deployment.

**How much do Meta AI smart glasses cost?**

Meta's AI smart glasses start at $299, according to Glasses.com. Models with Transitions® lenses start at $379. The glasses support prescription lenses and include hands-free Meta AI access, open-ear audio, and a built-in camera. Multiple frame styles and lens options are available, and insurance benefits can be applied to the purchase.

**What use cases benefit most from the Muse Spark upgrade on Meta glasses?**

AI Navigate identifies cooking assistance, navigation cues, and guidance in unfamiliar environments as the scenarios where the Muse Spark upgrade will be most felt. These are hands-free situations where contextual reasoning — understanding what to do next based on what the camera sees — matters more than simple object identification, which was the limit of Llama 4 on the glasses.
