Select a model by task

Match a built-in preset to the task. Start small; move up only if output quality does not meet your bar.

No built-in LLM is included in Aspose.LLM. The library is a local inference runtime: you choose which open source model to use, and the model file is obtained separately and stored on your own machine. Model files are covered by the license of the model publisher, not by your license agreement with Aspose Pty Ltd.

Check the license of the model a preset resolves to before using it commercially. Licenses are listed in Supported presets.

Decision tree

1. Do you need vision (image input)?

   • Yes → pick a vision preset based on size and image type.
   • No → continue.

2. Is the task coding?

   • Yes → DeepSeekCoder2Preset.
   • No → continue.

3. Does the task require explicit step-by-step reasoning?

   • Yes → DeepseekR1Qwen3Preset or Oss20Preset (budget 1024-2048 MaxTokens).
   • No → continue.

4. How much memory do you have?

   • 4-8 GB → Llama32Preset or Phi4Preset.
   • 12-16 GB → Qwen25Preset or Qwen3Preset.
   • 24+ GB → any preset; Oss20Preset for best quality.

After you pick

Override the default values where they do not fit your scenario. See Customizing presets.

If none of the built-ins fit, bring your own GGUF.

Before you ship

Check the license of the model you selected. Aspose.LLM supplies the runtime, not the model. Whichever model you load, its terms come from the party that published it and they apply to your product. They are not part of, and are not covered by, your license agreement with Aspose Pty Ltd. Some open source models allow commercial use with no strings attached, others attach conditions such as attribution or an acceptable use policy, and a few exclude commercial use or withdraw it above a revenue threshold. Supported LLMs lists the license of every family the SDK ships a preset for.
