Syntic AI ships in three tiers — Fast, Standard, and Pro. Each is built for different kinds of work and each draws from your rate limit at a different rate. Dispatching Pro on a job Standard could handle burns tokens for no gain and slows you down in the process. This guide shows you how to pick the tier that ships the outcome efficiently and keeps you comfortably within your rate limits.
Which tiers you have and how high your limit goes both depend on your Syntic plan. Free includes Fast and Standard; Pro and Max add Syntic AI Pro and more headroom.
Meet the three tiers
Think of them as different tools for different jobs.
| Tier | Rate-limit use | Best for |
|---|---|---|
| Syntic AI Fast | Lightest | Quick answers, summaries, simple extraction — anything you want done instantly |
| Syntic AI Standard | Moderate | Coding, writing, analysis, multi-step workflows — your versatile default |
| Syntic AI Pro | Heaviest | Deep research and complex reasoning that genuinely needs sustained thinking |
Fast is lightweight and quick. It's built for everyday lookups and rivals the reasoning depth of last-generation Standard models. When you need a quick answer, a basic summary, or a synthesis, Fast ships it almost instantly. It's also the most efficient with your rate limit.
Standard is the daily driver. It brings strong reasoning to the work you do every day — coding, writing, analysis, research, and complex problem-solving. Responsive enough for real-time collaboration and capable enough that most jobs won't outgrow it. It also handles computer use, vision, and document and spreadsheet creation well — making it a versatile default. If you're not sure which tier to pick, start here.
Understanding rate limits
Your rate limit caps how many tokens you can use in a given window. The tiers consume tokens at different rates: Fast is the lightest, Standard is moderate, and Pro uses the most because it reasons more deeply.
Lighter tiers are more "efficient" with your limit — you can ask more with fewer tokens. Pro burns more tokens because it does more thinking. But if you dispatch Pro on a job Standard could handle, you're spending limit unnecessarily.
One thing that helps: both Standard and Pro feature adaptive extended thinking, which means Syntic AI calibrates reasoning depth to the problem. Simple questions get fast answers; complex ones get more thinking. That makes both tiers more token-efficient than their predecessors — even with extended thinking on, easy questions don't eat into your limit as much as before.
When to use each tier
To balance rate limits with output quality, pick by the kind of outcome you need.
Use Fast for:
- Simple, straightforward questions with short answers
- Quick lookups or categorization
- Extracting specific information from text
- Simple summarization or synthesis
- Anything you want done instantly without complex reasoning
Use Standard for:
- Writing and content creation
- Coding — debugging, writing new code, refactoring
- Analysis that needs reasoning but isn't extreme
- Customer-support conversations with context and nuance
- Multi-step problems and workflows
- Most general-purpose work where you're not sure which tier to use
Use Pro for:
- Deep research and analysis
- Complex reasoning that requires multiple steps
- Specialized tasks where accuracy is critical
- Problems where you've tested with Standard and it struggled
- Long documents requiring sustained concentration to understand
What this looks like in practice
A few common jobs.
| Job | Pick | Why |
|---|---|---|
| Debugging code | Standard | Strong coding capability, fast feedback, clear bug identification |
| Summarizing articles | Fast | Straightforward content extraction without complex reasoning |
| Analyzing complex research papers | Pro | Deep analysis across long specialized documents, including methodology critique and forward-looking insight |
Picking tiers over time
One thing worth knowing: a new Syntic AI release isn't a patch on the old one. Each release is a separate training run, which means a job that used to suit Pro might sit more naturally with Standard now, or the other way around.
The balance shifts with each release, so re-test your assumptions when new tiers ship. Spend a few minutes running your go-to jobs across all three. If you're on the free plan, upgrading gives you all three tiers and a higher rate limit, so you have more room to try everything when a new release lands.
