GPT-6 Luna vs GPT-6 Sol
什麼情況選哪一個
gpt-6-luna 和 gpt-6-sol 在規格上完全相同:兩者均具備 1050000-token 的上下文、128000-token 的最大輸出、文字和影像輸入與文字輸出、相同的聊天/視覺/程式碼/工具/推理標籤、可選的思考功能,以及 2026-09-22 的發佈日期。兩者的差異在於價格:gpt-6-sol 各個項目的費用都貴 20x(輸入 $2 對 $0.1,輸出 $10 對 $0.5,快取讀取 $0.2 對 $0.01),因此請將 gpt-6-luna 作為高流量及長上下文任務的預設選項。只有當使用您自己的提示詞進行測試後證明值得這 20x 的費用時,才去選擇 gpt-6-sol;gpt-6-luna 甚至具備較晚的知識截止日期,為 2026-05 對上 2026-04。

同一段提示詞,兩個模型,經閘道實測
GPT-6 Luna 通過 · 3 sentences
Enabling reasoning typically makes the model process more information and generate more internal tokens before producing its answer. Because usage is billed by tokens—and reasoning may also route requests to a more expensive model—the cost per request can rise sharply. If request volume stayed similar, that higher cost per request could explain why the bill doubled.

GPT-6 Sol 通過 · 3 sentences
Enabling reasoning made the model generate extra internal tokens to work through each request, and those tokens are billed even though users don’t see them. If request volume stayed roughly the same, more billed tokens per request could explain why the bill doubled. We should check the usage breakdown to confirm, then lower reasoning effort or limit it to tasks that need it.

```python def longest_run(xs): if not xs: return 0 best = cur = 1 for i in range(1, len(xs)): if xs[i] == xs[i - 1]: cur += 1 else: cur = 1 best = max(best, cur) return best ``` The original code counted matching *adjacent pairs* rather than items, so a run of length `n` was reported as `n - 1`, and a single-item input returned `0`. This version counts the current item as part of each run and updates `best` at every index, including the last; it returns `0` for an empty input.

Starting each run at 1 counts its first item, and updating `best` on every iteration ensures a run that reaches the last index is included.

Introducing Prompt Cache, a new API gateway feature that recognizes repeat prompt prefixes and reuses provider-side cached context across supported models. Teams can route requests to different AI providers while preserving eligible cache hits, reducing redundant input processing and helping lower latency and token costs. Configure cache policies in one place, monitor hit rates by provider, and keep existing client integrations unchanged. The gateway applies provider-specific rules automatically, so developers do not need to build separate caching logic for each endpoint. Which workflows could benefit from faster responses and predictable spend? Prompt Cache is available today in preview for eligible accounts, with usage details, supported providers, and setup guidance in the dashboard. Start with one route, compare results, then expand.

Today, we’re introducing cross-provider prompt caching for our API gateway, helping teams reuse repeated prompt content when routing requests among supported AI providers. The gateway identifies eligible prompt prefixes, stores cache references, and applies them to subsequent requests where provider capabilities allow. Why send the same context again if it can be reused? With fewer duplicate input tokens, applications can reduce costs and improve latency without changing how developers call the gateway. Configure caching by route, monitor hit rates and savings in your dashboard, and keep existing provider fallback rules in place. Availability and cache behavior vary by provider, so the gateway reports eligibility and usage for each request. Get started today with our documentation and test your existing workloads.

GPT-6 Luna 和 GPT-6 Sol 哪個比較便宜?
以「輸入 / 1M tokens」來看,GPT-6 Luna 比較便宜($0.1 對 $2,相差 20×)。其他項目的結果可能相反,完整價目請看上表;實際成本要看你的用量組合。
可以只串接一次,就對 GPT-6 Luna 和 GPT-6 Sol 做 A/B 測試嗎?
可以。兩個模型都走同一個 OpenAI 相容端點,用的也是同一把 API 金鑰,切換時只要改一行裡的模型名稱字串。你可以把一部分流量分別導到兩邊,再直接比較帳單。
GPT-6 Luna 與 GPT-6 Sol 支援提示詞快取嗎?
支援。兩者的快取讀取費率都低於輸入費率,所以前綴已經進快取的工作負載,實際成本會比官網價算出來的低。確切的快取讀取價格請見上方定價表。
