Amazon Bedrock – Anthropic Claude 3.5 Sonnet, one of the AI models you can select in Soracom Flux AI Actions, will reach end of support on March 1, 2026 (see Amazon Bedrock Model Lifecycle).

Consequently, AI actions in Flux apps that utilize this model will be disabled after March 1, 2026. If you are using Amazon Bedrock – Anthropic Claude 3 Sonnet, please switch to another AI model by March 1, 2026.

You can view the available AI models for Soracom Flux AI Actions in the Soracom Flux documentation.

Soracom Flux is an IoT automation service that enables business efficiency and automation by combining processes such as notifications and generative AI-based analysis using IoT data collected from sensors, cameras, and other devices.

Using Soracom Flux's app template feature, IoT apps can be created simply by selecting a template optimized for a representative use case. Customers can also customize them as needed with minimal parameter adjustments.

We have now added a new app template, "Analyze and Notify Using SoraCam Videos via Harvest Files".

For an overview of the template, estimated costs, and specific usage instructions, please visit the IoT Template Gallery (Japanese).

Please note that this template is currently only available for customers located in Japan.

We have added a new action, Collect Message Action (Japanese), to Soracom Flux.

The Collect Message Action aggregates actions that have been branched within a Flux app or split using the Send event for each feature.

For example, after executing a RTSP Camera Image Action and an AI Action targeting multiple RTSP compatible cameras, you can then execute subsequent notifications collectively.

The Collect Message Action is available on the Standard Plan and Enterprise Plan.

For more information, see Collect Message Action (Japanese).

We added a preview feature to Soracom Harvest Files so you can check image and text files directly from the User Console without downloading them.

Select a file in the console to open a preview, which is helpful when you want to quickly confirm its contents before downloading.

Previewing a file counts as a Harvest Files read, so charges apply based on the amount of data displayed, just like when downloading.

For more details, please refer to Soracom Harvest Files.

Note: Depending on your device, even LTE devices may be affected by the 3G shutdown. Please contact your vendor for details.

Note: KDDI and SoftBank have already terminated their 3G services in Japan.

Affected Subscriptions

The following subscriptions support 3G service on the NTT Docomo:

We have added a new action, Bounding Box Action (Japanese), to Soracom Flux.

The Bounding Box Action sets a border frame around the image at the specified URL. By setting this frame, you can explicitly indicate the target area within the image for subsequent actions that use it.

For example, you can use the Bounding Box Action to specify the target area on an image acquired via the RTSP Camera Image Action, and then instruct the AI Action to "detect objects within the red box," allowing you to perform AI analysis on a specific region within the image.

The Bounding Box Action is available on the Standard Plan and Enterprise Plan.
