# Text models (LLMs)

In Pletor, text models' primary role is often behind-the-scenes: refining user inputs, processing brand guidelines, and creating optimized prompts for image and video generation models. They act as intelligent intermediaries that transform raw context into polished instructions for other AI nodes.

## What text model should I pick?

The right model depends on your specific workflow requirements. When in doubt, start with a balanced model you already know, and adjust based on your use case and results:

| Use case                                    | Recommended models                           |
| ------------------------------------------- | -------------------------------------------- |
| Prompt enhancement                          | Claude Sonnet 4.6, Gemini 3.1 Flash, GPT-5.2 |
| Large context or brand guideline processing | Gemini 3.1 Pro, Claude Opus 4.6, GPT-5.2     |
| Fast, real-time workflows                   | Claude Haiku 4.5, Gemini 2.5 Flash Lite      |
| Resource-conscious workflows                | GPT-4.1 Mini                                 |

## Choosing the right model

### Best practices

* **Match model to task**: Use faster models for simple prompt crafting, balanced models when you need more creativity.
* **Consider context needs**: If your workflow involves extensive brand guidelines or reference materials, choose models with larger context windows.
* **Test different models**: The same prompt can yield different styles, experiment to find what works best for your use case.

### Go-to models (for most workflows)

Start with these reliable, balanced models that handle the majority of prompt enhancement and context processing tasks:

* **Claude Sonnet 4.6** - Smart, efficient, creative model perfect for routine prompt enhancement and context processing in most workflows.
* **Gemini 3.0 Flash** - Perfect when speed matters more than complexity or creativity. Ideal for quick prompt generation and real-time workflows.
* **GPT-5.2** - Generalist, reliable model performing well across all types of prompt enhancement and simple context processing tasks.

### When working with extensive or multimodal context

Select these models for complex briefs and large amounts of context:

* **Gemini 3.1 Pro** - Handles complex briefs with extensive brand guidelines material or media creative analysis (including video material). Can process and reference large amounts of context simultaneously.
* **Claude Opus 4.6** - Powerful, sophisticated model for complex context processing and advanced prompt optimization requiring deep reasoning. Does not handle videos and takes longer than Sonnet.
* **GPT-5.2** - OpenAI's most advanced model with superior reasoning capabilities and enhanced creative output. Similar to Claude Opus.

### When speed is your priority

Choose these models when you need fast generation and real-time performance:

* **Gemini 2.5 Flash Lite** - Cutting-edge model with enhanced performance and capabilities. Use when you want high-speed agents.
* **Claude Haiku 4.5** - A fast, yet great model by Anthropic.
* **GPT-4.1 Mini** - Lightweight version optimized for common workflow processing and prompt refinement when resources matter. Delivers poorer results than Gemini 2.0 Flash or GPT 4.1 (at least in our opinion).
