Ollama now supports all GGUF models from Hugging Face, allowing access to over 45,000 community-created models through Spring AI's Ollama integration, runnable locally.

We'll explore using this new feature with Spring AI. The Spring AI Ollama integration can automatically pull unavailable models for both chat completion and embedding models. This is useful when switching models or deploying to new environments.

Setting Up Spring AI with Ollama

Install Ollama on your system: https://ollama.com/download.

Tip: Spring AI also supports running Ollama via Testcontainers or integrating with an external Ollama service via Kubernetes Service Bindings…

On behalf of the team and everyone who contributed, I am pleased to announce the first Release Candidate for Spring AMQP 3.2 generation.

Some highlights of this release:

• The server side retry logic (manual DLX) has been improved for a new retry-count header to make Spring AMQP compatible with recently released RabbitMQ 4.0.x. The MessageProperties.incrementRetryCount() has to be called before re-publishing message to DLX. The previous logic based on the x-death header does not work anymore since RabbitMQ 4.0.x ignored any x-* headers sent from the client;
• More Open Telemetry semantic tags are exposed via Rabbit Listener and Template observations;
• Some bugs and internal code improvement.
…
