Every PageCrawl.io plan includes AI credits that work automatically with no setup. For most users, the included credits are all you need. This guide is primarily for users who want to bring their own API key (BYOK) and choose a specific model, covering budget options to premium models with cost comparisons based on 2026 pricing.
Using included credits? You don't need to choose a model. PageCrawl automatically uses optimized models on your behalf. Each 4,000-token block costs 1 credit (Basic tier) or 10 credits (Pro tier, Ultimate plan only). See AI-Powered Change Detection for details on how credits work.

Why AI Models Matter
AI models enhance website monitoring by automatically summarizing changes, assigning priority scores, and distinguishing meaningful updates from noise.
PageCrawl.io supports four AI providers:
- OpenAI - GPT-5 family, reliable and fast
- Google Gemini - Gemini 3 family with competitive pricing
- Anthropic Claude - Claude 4.5 and 4.6 series, high accuracy and premium quality
- OpenRouter - A marketplace that gives you access to 200+ AI models from different providers, all through a single account and API key
Understanding Tokens and Costs
What is a Token?
A token is roughly 4 characters or about 3/4 of a word. AI providers charge based on tokens processed:
- "Hello world" = ~3 tokens
- A typical paragraph = ~100 tokens
- A blog post (1,000 words) = ~1,300 tokens
- A full webpage = ~2,000-10,000 tokens
How PageCrawl Uses Tokens
PageCrawl's AI costs are dominated by input tokens (the page content sent to AI). Output tokens are minimal because summaries are typically just 1-2 paragraphs (~100-200 tokens).
Typical token usage per check:
- Simple page (blog post, article): ~1,000-2,000 tokens
- Medium page (product page, news): ~2,000-5,000 tokens
- Large page (documentation, e-commerce): ~5,000-10,000 tokens
Example cost calculation (Gemini 3 Flash at ~$0.40/M input):
- 2,000 token page = $0.0008 per check (~1,250 checks per dollar)
- 5,000 token page = $0.002 per check (~500 checks per dollar)
Example cost calculation (Claude Opus 4.6 at ~$15/M input):
- 2,000 token page = $0.03 per check (~33 checks per dollar)
- 5,000 token page = $0.075 per check (~13 checks per dollar)
Since output is just a short summary (~150 tokens), output costs add less than 10% to the total. Additionally, AI only runs when a meaningful change is detected on the page. PageCrawl's advanced change detection infrastructure filters out tiny, insignificant changes before they ever reach AI, so you only spend tokens on changes that actually matter.

Recommended Models by Use Case
PageCrawl.io only calls AI when a page actually changes. If you monitor 1,000 pages and only 150 change, you pay for 150 AI requests, not 1,000.
The PageCrawl.io settings page provides three Quick Select tiers to help you choose:
Best / Most Capable
For complex pages where accuracy matters most (legal documents, terms of service, compliance monitoring).
| Provider | Model |
|---|---|
| OpenAI | GPT-5.2 |
| Anthropic | Claude Sonnet 4.6 |
| Google Gemini | Gemini 3.1 Pro |
| OpenRouter | Claude Sonnet 4.6 |
These models deliver the most accurate results but cost significantly more. Only use them for pages where precision is critical.
Good Quality (Recommended for Most Users)
Best balance of quality and cost for everyday monitoring.
| Provider | Model |
|---|---|
| OpenAI | GPT-5 Mini |
| Anthropic | Claude Haiku 4.5 |
| Google Gemini | Gemini 3 Flash |
| OpenRouter | Gemini 3 Flash |
This tier is the sweet spot for most BYOK users. These models handle the vast majority of monitoring tasks reliably and affordably.
Budget
Lowest cost for high-volume monitoring where some accuracy trade-off is acceptable.
| Provider | Model |
|---|---|
| OpenAI | GPT-5 Nano |
| Anthropic | Claude Haiku 4.5 |
| Google Gemini | Gemini 2.5 Flash Lite |
| OpenRouter | DeepSeek V3.2 |
Good for simple page monitoring (blog posts, news, documentation) where you want to keep costs as low as possible.
Best Models by Content Type
| Content Type | Budget Option | Recommended | Premium |
|---|---|---|---|
| Blogs, News, Docs | GPT-5 Nano | GPT-5 Mini | - |

Real-World Cost Examples
Costs can vary significantly. These are estimates only. Your actual costs depend on:
- Page complexity and content length
- How often pages change
- Deep Analysis setting (on = full page, off = changes only)
- Max token settings
Token usage by page type:
- Simple pages (blogs, docs): ~500 tokens
- Average pages: ~2,000 tokens
- Content-heavy pages: ~5,000-10,000 tokens
- Complex pages (e-commerce, SPAs): 10,000-25,000+ tokens
Recommendation: Start with budget-friendly models like GPT-5 Nano or Gemini 2.5 Flash Lite and set strict monthly limits to avoid unexpected bills.
Controlling Token Usage
You can reduce token usage in PageCrawl.io settings:
- Deep Analysis off: Only send changed text to AI (lower tokens, less context)
- Deep Analysis on: Send entire page for better understanding (higher tokens)
- Max tokens limit: Set a maximum per request (falls back to diff if exceeded)
- Monthly request limits: Set max AI requests per month to cap costs
- Per-page daily limit: Prevent noisy pages from consuming all your AI budget
Note: Check your actual token usage in PageCrawl.io's AI statistics to estimate your costs accurately.

- Page override - applies to individual pages
Example strategy:
- Workspace default: Gemini 2.5 Flash Lite (cheapest)
- E-commerce template: GPT-5 Mini (good balance)
- Legal template: Claude Sonnet 4.6 (high accuracy)
- Critical page: GPT-5.2 (most capable)
Tips for Optimizing Costs
- Start with the Good Quality tier - GPT-5 Mini, Gemini 3 Flash, or Claude Haiku 4.5 offer excellent quality at reasonable prices
- Use templates - Group similar pages with the same model to optimize costs by content type
- Check frequency doesn't affect AI costs - AI only runs when changes occur, not on every check
- Set monthly limits - Use the "AI Requests Per Month" setting to cap spending
- Monitor token usage - Check the token statistics in your AI settings to understand your actual costs
- Use per-page daily limits - Prevent frequently updating pages from consuming all your budget
