Additionally, the latest Ollama engine offers advanced memory management, streaming tool calls, and support for quantized deployments, enabling more performance-conscious model selection than ever before.

1. Source Models (Base Models)

Source models are foundational LLMs trained on large-scale datasets without task-specific fine-tuning. They form the basis for most other models and are capable of understanding and generating natural language in a wide range of general-purpose scenarios.

• Predicting text continuations
• Answering open-ended questions
• Summarizing content
• Generating structured or unstructured text

Many source models now utilize Mixture of Experts (MoE) architectures, which offer higher efficiency and accuracy. Support for long context windows (up to 256k tokens) in models like LLaMA 3.3 and DeepSeek-R1.

• LLaMA 3.3 / 4 Scout: High-parameter MoE models that offer multimodal support, long context, and fine-grained reasoning.
• Phi-4: A compact, high-efficiency language model designed for edge and CPU-only devices.
• Mistral-7B-Instruct: Versatile and lightweight, ideal for laptops and real-time interaction.

2. Fine-Tuned Models

Fine-tuned models are personalized offspring of base models that have been retrained with task-specific or domain-specific data. They are capable of delivering the best performance on focused applications, such as instruction following, code generation, or conversational AI.

• Instruction tuning
• Code completion
• Chatbot optimization
• Domain-specific reasoning

Support for streaming tool responses, allowing real-time output from fine-tuned agents. Integration with "thinking mode", enabling step-by-step explanations during complex reasoning tasks.

• WizardLM-2 8B: A refined conversational agent with advanced instruction-following and logic reasoning.
• DeepSeek-Coder 33B: Fine-tuned for multi-language code generation and debugging with chain-of-thought capabilities.
• StableCode-Completion-Alpha-3B: Specialized for completing partial code, suitable for IDE integration.

3. Embedding Models

Embedding models transform text into vector representations (embeddings) that reflect semantic relationships between ideas. Such vectors are crucial for search, classification, clustering, and recommendation systems.

• Semantic search
• Document similarity analysis
• Text clustering
• Question-document matching

Ollama now includes optimized embedding pipelines with faster encoding and better memory estimates. Embedding models support low-resource inference, enabling semantic processing on local devices.

• Ollama-e-7B: A general-purpose embedding model supporting large-scale text similarity and search applications.
• all-MiniLM-L6-v2 (Sentence Transformers): A lightweight, efficient model producing sentence-level embeddings.

4. Multimodal Models

Multimodal models process and integrate inputs from multiple data types, such as text and images, within a single architecture. These models enable sophisticated reasoning over visual and linguistic information.

• Visual question answering (VQA)
• Document understanding (OCR + context)
• Image captioning and interpretation
• Cross-modal retrieval

Ollama now supports native multimodal inference, including models with image-to-text, text-to-image reasoning, and multi-image comparison. Many models support streamed outputs, improving usability in real-time applications.

• LLaVA 1.5 / 1.6: A general-purpose multimodal model for visual understanding and VQA.
• Qwen-VL 2.5: Capable of document OCR, layout analysis, translation, and visual reasoning.
• Gemma 3 (Multimodal): Accepts multiple images as input and performs visual comparisons and context linking.
• Moondream 2 / 1.8B: Lightweight visual models suitable for running on CPU and mobile environments.

To be more specific, Ollama has gone for multimodal models that are native to it, and these models are the best that one can find because they can do all at once and their capacity is large. It is also further allowing the users to communicate with AI systems that are capable of understanding not only the text but also the images. This indeed is now representing a huge step forward in local AI capabilities which are now enabling the users to execute highly complex vision-language tasks right on their gadgets.

Here are some of the most striking models:

• Meta Llama 4 Scout (109B parameters)
  A general multimodal reasoning behemoth. It is very good at describing the images, naming objects, and responding to context or location-based questions.
• Gemma 3
  This version is a multi-image input model; it can think up ways of connecting different images and perform reasoning behind them. That makes it perfect for tasks about advanced image comparison and storytelling.
• Qwen 2.5 VL
  This version is mainly aimed at tasks including document scanning, OCR (Optical Character Recognition), and multilingual translation. So, it is a perfect gift for those who constantly work with forms, printed materials, or visual data in more than one languages.

The key to such models is, they tap the Mixture-of-Experts (MoE) idea which allows them to change between task-specific sub-models. Hence, they can make a very significant jump in both precision and budget of computational resources, especially while solving high-complexity multi-modal problems such as blending vision and language.

In 2025, Ollama launched new language models that are targeted at particular industries. The models are suitable for tasks that require sight, thinking, programming, and very minor tasks. Additionally, they offer an option for local AI implementation, which provides superior performance, more intelligent reasoning, and better efficiency.

These models are available in a variety of sizes—from lightweight versions ideal for laptops and edge devices, to full-scale deployments on high-performance workstations and servers.

Ollama's recent updates (versions 0.8.0 and 0.9.0) focus heavily on improving the developer experience with practical new features designed to boost productivity and transparency:

• Streaming Tool Responses: Models can now deliver partial answers in real-time while making tool calls, enhancing chatbot responsiveness, and enabling smoother real-time interactions.
• "Thinking" Mode: Available in models like DeepSeek and Qwen 3, this mode allows the AI to explicitly show its reasoning steps before providing a final answer. This transparency aids debugging and fosters trust in AI outputs.
• Improved Logging and Monitoring: Developers gain access to detailed memory usage estimates, helping to optimize resource allocation and prevent out-of-memory issues during model deployment.

These improvements collectively make Ollama a more robust and developer-friendly platform for building cutting-edge AI applications.

Ollama's 2025 roadmap is focused on pushing the limits of performance and efficiency to make local AI deployment faster, more scalable, and accessible across a wide range of devices. Key areas of focus include:

Advanced Quantization Techniques

Quantization is a crucial technique for reducing the size and computational demands of large language models without significantly compromising their accuracy. Ollama is pioneering INT4 (4-bit) and INT2 (2-bit) quantization methods, which compress model weights far beyond the standard 8-bit or 16-bit precision.

Benefits:

• Models become significantly smaller, reducing memory footprint and storage requirements.
• Lower precision calculations translate into faster inference times and lower energy consumption.
• Enables deployment on edge devices, such as smartphones, tablets, and embedded systems, opening up new use cases for on-device AI.

Enhanced Memory Management

Longer conversations and processing of documents have been at the limit of the model's ability to efficiently remember the context. Ollama offers solutions such as:

• Streaming KV-Cache: This method allows key-value pairs used in the attention mechanisms of transformers to be streamed and processed partly, instead of all at once, drastically reducing memory usage.
• Optimized Context Windows: Increasing a context window allows models to access longer memory and perform reasoning over more tokens during interactions, resulting in richer, more coherent chats and better understanding of lengthy documents or codebases.

These upgrades allow for more seamless, context-rich conversations without taxing hardware resources.

Inference Speed and Scalability

Ollama is investing in the following to satisfy the requirements of production environments and enterprise applications:

• Multi-GPU Pipeline Parallelism: Distributes the steps of model inference among different GPUs so stages can run simultaneously, efficiently reducing latency and increasing throughput.
• Dynamic Batching: Groups multiple inference requests on-the-fly instead of handling them one by one, maximizing hardware utilization and speeding up response times, especially during high usage.

These innovations aim to deliver near-real-time AI responses even under heavy workloads, making Ollama suitable for both experimental and mission-critical applications.
