v1.0.26 Release Notes

Released 2026-09-28

v1.0.25 -> v1.0.26

Summary

Usage records now retain tool-call identifiers, while routing and execution improve long-context selection and prompt-cache continuity. Reasoning guidance can be fetched in a single request.

翻譯

Usage 紀錄現在會保留工具呼叫識別碼，並改善長內容模型選擇與提示快取延續性。推理指引也可透過單次請求取得。

Recommended upgrade

Cache hit rates on codex@, grok@ and grok-oauth@ are maximised from this version on. Each now sends the cache key its endpoint actually routes on, and the execution history stays byte-identical between sends so the cached prefix keeps growing instead of resetting. Measured on the same repeated task:

Lower spend and lower latency come from the same change: what used to be re-sent at full price is now served from cache. openai@ already cached well and is unchanged at 94%; it and cloudflare@ now send the key explicitly.

翻譯

自本版起 codex@、grok@、grok-oauth@ 的快取命中率最大化。三者現在都會送出各自端點實際用來路由的快取識別碼，而執行歷史在每次送出之間保持位元組一致，快取前綴因此持續成長而非重置。同一項重複任務的實測：

模型前綴	之前	之後
codex@	16%	87-93%
grok@	快取前綴卡在 13.5K	71%
grok-oauth@	未送快取識別碼	68%

花費與延遲同時下降：過去以全額重送的內容現在由快取提供。openai@ 原本命中率就好，維持 94% 不變；它與 cloudflare@ 現在也會明確送出識別碼。
