    STACKIT AI Model Serving: New Model Release GPT-OSS 20B (Replacement for Llama-8B and Nemo)

    Mar 4, 2026

    We are excited to announce that we are upgrading our model lineup by introducing openai/gpt-oss-20b, which will serve as the successor to our current Mistral-Nemo and Llama 3.1 8B offerings.

    By leveraging 4-bit (MXFP4) quantization, this new 20-billion parameter model provides a significant boost in reasoning capabilities while maintaining the low-latency performance our customers expect. Applications such as real-time chatbots, retrieval-augmented generation (RAG), and agentic workflows will benefit from improved tool-calling and higher throughput.

    Deprecation Notice

    As part of this transition, we are officially deprecating the following models:

    • neuralmagic/Mistral-Nemo-Instruct-2407-FP8
    • neuralmagic/Meta-Llama-3.1-8B-Instruct-FP8

    We kindly ask all customers to migrate their workloads to the new model openai/gpt-oss-20b before 4 June 2026.

    STACKIT AI Model Serving: New Model Release Qwen3-VL-Embedding-8B as Multi-Modal Embedding

    Feb 5, 2026

    We are excited to announce the addition of Qwen3-VL-Embedding-8B to our shared LLM model portfolio. This is a state-of-the-art multimodal embedding model designed to bridge the gap between visual and textual data.

    Unlike traditional text-only models, Qwen3-VL-Embedding-8B projects both text and images into a unified semantic vector space. This release unlocks powerful Cross-Modal Retrieval capabilities for your applications, allowing you to perform text-to-image search, image-to-text search, and complex multimodal RAG (Retrieval-Augmented Generation) workflows.

    Key Upgrades

    This generation delivers comprehensive improvements in vector representation and retrieval accuracy:

    • Unified Multimodality: Computes semantic embedding vectors from chat messages containing both text and images.
    • High-Fidelity Embeddings: Features an output dimension of 4096 and 8 Billion parameters for deep semantic nuance.
    • Extended Context: Supports a maximum input of 32,000 tokens, enabling the processing of dense documents and high-resolution visual inputs.
    • Multi-language Reach: Optimized support for over 30 languages.
