## Three findings

1. **Context size and price are independent.** Doubao-Seed-2.0-Lite: 256K at $0.075/1M. Kimi K2.7 Code HighSpeed: 256K at $2.073/1M. 28x for the same capacity.
2. **The cheapest 1M window is not a flagship.** GLM-5.3-Flash at $0.08/1M = $0.08 per full pass; Kimi K3 at $2.90.
3. **4M exists and is not the priciest.** MiniMax Text-01: $0.14/1M, $0.56 per full 4M pass - less than one full pass on Kimi K3.

## What a full pass buys

- ~128K tokens: a 300-page book or a mid-sized repo's relevant files
- ~1M tokens: a large codebase or a full documentation set
- ~4M tokens: multiple books or a small product's source history

Most long-context requests fill 10-20% of the window, cutting these figures 5-10x.

## FAQ

**What is the cheapest 1M-context model?**
GLM-5.3-Flash at $0.08 per 1M input tokens, so one full-context pass costs about $0.08. Kimi K3 also offers 1M context but at $2.90 per 1M input, roughly 36x more for the same volume.

**Which model has the largest context window?**
MiniMax Text-01 lists a 4M-token context window, the largest in the catalog. A full 4M-token pass costs about $0.56 at its $0.14 per 1M input price.

**Does a bigger context window always cost more?**
No. Context size and price are independent. Doubao-Seed-2.0-Lite is the cheapest 256K model at $0.075 per 1M input, while Kimi K2.7 Code HighSpeed costs $2.073 per 1M input at the same 256K window.

**Are these prices per request or per token?**
Per token. You pay for the tokens you send and receive, not for the size of the window. A 10K-token request on a 1M-context model costs 1% of a full-context pass.
