Models are the AI systems that power every conversation in Saga — GPT, Claude, Mistral, DeepSeek, Gemini, and others. Each comes from a different provider and has different strengths. Your organization’s admin controls which models are available to you. You don’t need to understand the technical details behind each model. What matters is knowing how to read the indicators and pick the right one for the task at hand.

​
Capability indicators

When you hover over a model in the assistant selector, four indicators appear: Speed — how fast the model responds, on a scale from 1 to 5. Faster models are better for quick tasks like summarizing a paragraph or translating a sentence. Slower models tend to be more thorough. Intelligence — how nuanced and accurate the model’s reasoning is, on a scale from 1 to 5. Higher intelligence means the model is better at complex analysis, multi-step reasoning, and catching subtle distinctions. The trade-off is usually speed. Capacity — how much text the model can process in a single conversation, shown in approximate words or pages. This matters when you’re working with long documents or asking questions that require the AI to consider a lot of material at once. Knowledge cutoff — the date up to which the model was trained. The model doesn’t know about events, legislation, or case law published after this date. If you need current information, combine the model with web search.

​
Thinking mode

Some models can show their step-by-step reasoning before giving a final answer. When this happens, an expandable “Thinking” section appears above the response. This is useful for complex legal questions — multi-jurisdiction comparisons, risk assessments with several variables, or any analysis where the reasoning matters as much as the conclusion. Seeing the model’s thought process lets you spot where it made assumptions or missed a consideration. If you don’t need the reasoning and want a faster answer, click Skip thinking for a faster answer to get the response directly.

Choosing the right model

There’s no single best model — it depends on what you’re doing.
  • Quick tasks (summarize, translate, draft a short response): pick a fast model. You don’t need heavy reasoning for straightforward work.
  • Complex analysis (multi-party contract review, regulatory comparison, risk assessment): pick an intelligent model. The extra processing time is worth the more nuanced output.
  • Large document context (long contracts, extensive due diligence sets): check capacity. A model with higher capacity can hold more of your material in context at once.
  • Current information (recent legislation, recent case law): check the knowledge cutoff, and enable web search if needed.

​
Enabled models

Your admin decides which models are available in your organization’s Saga instance. If you need a model that isn’t showing up in the assistant selector, ask your admin to enable it from the workspace settings.
