Token Economics
| Feature | Claude (Anthropic) | ChatGPT (OpenAI) | Gemini (Google) | Copilot (Microsoft) | Meta AI | Grok (xAI) |
|---|---|---|---|---|---|---|
| Flagship model (API, per 1M tokens in / out) | Fable 5: $10 / $50 | GPT-5.6 Sol: $5 / $30 | 3.1 Pro: $2 / $12 (3.5 Pro pricing TBA) | No per-token API (Azure OpenAI rates) | Muse Spark 1.1 (API preview, pricing TBA) | Grok 4.5: $2 / $6 (2x above 200K prompt) |
| Workhorse model (API, per 1M tokens in / out) | Sonnet 5: $3 / $15 ($2 / $10 intro thru Aug 2026) | GPT-5.6 Terra: $2.50 / $15 | 3.5 Flash: $1.50 / $9 | Copilot Credits: $0.01/credit (Studio) | Llama 4 Maverick: ~$0.15–$0.50 via hosts | Grok 4.3: $1.25 / $2.50 |
| Budget model (API, per 1M tokens in / out) | Haiku 4.5: $1 / $5 | GPT-5.6 Luna: $1 / $6 | 2.5 Flash-Lite: $0.10 / $0.40 | N/A (seat + credit model) | Llama 4 Scout: ~$0.08–$0.20 via hosts | Grok 4 Fast: $0.20 / $0.50 |

Understanding Token Economics
AI models bill API usage in tokens — chunks of text roughly three-quarters of a word each. Every request pays for input tokens (what you send, including documents and conversation history) and output tokens (what the model writes back). Output tokens cost 5–6x more than input tokens on most models, so long generated reports cost far more than long prompts.
~750K words
What $10 buys in input on a flagship model (1M tokens)
10–100x
Price spread between flagship and budget tiers for the same task
Up to 90%
Input savings from prompt caching on repeated context
The practical takeaway: model routing is where the money is. Sending routine work (classification, summaries, data extraction) to a budget model and reserving flagship models for complex reasoning typically cuts API spend 40–60% with no quality loss where it matters. Batch processing (50% off on most platforms) and prompt caching compound those savings for automated workflows.
