Data source: /resources/getting-started/model-cost. Prices are blended for typical chats; Perplexity adds a per-request fee on top of token costs.

When to Choose Each Family

Google Gemini (2.5 Flash / 2.5 Pro)

• Pick if you want speed and the lowest costs (Flash) or strong analysis with great tool integration (Pro).
• Typical uses: Customer ops, bulk processing, research synthesis, data analysis.

OpenAI GPT (GPT-5, GPT-5 Mini, GPT-4o)

• Pick if you want broad capabilities with stable reasoning (GPT-5), ultra-low-cost OpenAI (Mini), or familiar multimodal chat (4o).
• Typical uses: General-purpose work, product ideation, technical Q&A, multimodal workflows.

Anthropic Claude (4 Sonnet, 3.5 Sonnet, Opus 4.1)

• Pick if writing quality and communication clarity matter most (4 Sonnet). Use Opus 4.1 only when you truly need maximum capability.
• Typical uses: Long-form writing, instruction design, collaborative editing, refined communication.

Perplexity (Reasoning / Deep Research)

• Pick if you need current web evidence with strong synthesis. Remember the extra request fee.
• Typical uses: Market scans, news validation, source-cited overviews.

Others

• Grok 4: Competitive new option at the Claude price tier.
• Qwen 3 Thinking: Value reasoning pick with very low blended cost.

Real Cost Examples (From Live Usage)

• Perplexity Reasoning, single short query: ~363 total tokens → about $0.0068 total (plus request fee if applicable).
• Claude 4.5 Sonnet, longer SEO chat: ~3,020 total tokens → about $0.05 total.

These reflect typical chat behavior (outputs ~3x inputs) and match our blended cost methodology.

• Evidence-backed answers: Perplexity Reasoning (mind the request fee).
• Budget reasoning (non-English/Chinese contexts too): Qwen 3 Thinking.

Methodology and Updates

We validate model behavior and costs with live logs across diverse tasks (analysis, writing, research, multimodal). Blended costs come from real conversational patterns where output tokens are typically ~3x input tokens. We track pricing and model availability and update this guide regularly.

FAQ

What is a “blended cost” and why does it matter?

It’s a single number per model that reflects typical chat usage (inputs + outputs), making apples‑to‑apples comparisons simple. It’s based on outputs being ~3x inputs on average.

Which model is the absolute cheapest for real work?

For most tasks, Gemini 2.5 Flash has the lowest practical cost per work done. If you prefer OpenAI-style behavior at low cost, GPT-5 Mini is a solid alternative.

Which model writes the best?

For clarity, structure, and tone, Claude 4.5 Sonnet is consistently the top pick.

Which model is the best all-rounder?

GPT-5 is the safest default for mixed tasks; Gemini 2.5 Pro competes closely, especially when tool integration matters.

How do Perplexity fees work?

You pay token costs plus an additional $5 per 1K requests (see “Additional Fees” on the pricing page). Great for evidence-backed answers; just factor the request fee into your estimates.
