From 0e994f959cd093b1ecbca3cbe13676fbff14faf5 Mon Sep 17 00:00:00 2001 From: Plateau Nguyen Date: Fri, 19 Jun 2026 10:59:02 +0700 Subject: [PATCH] feat(providers): explicit prompt cache for DashScope/Qwen (#1127) * feat(providers): explicit prompt cache for DashScope/Qwen Extend OpenAI-compat path with Anthropic-style cache_control:ephemeral inline blocks for Alibaba DashScope endpoints (provider_type=bailian or URL contains "dashscope"). Verified live: qwen3.6-plus / qwen3.5-plus / qwen3-coder-plus all return 99.7% cache hit rate on 6K-token prefix, yielding ~89% token cost reduction on cached prefix (90% Alibaba discount). - isDashScope(): 3-source detection (URL + providerType + name) handles reverse-proxied endpoints; covers both "dashscope" and "bailian" - buildRequestBody wraps system content with SplitSystemPromptForCache (exported from anthropic_request.go) using - Tool prefix cache: cache_control on last tool definition, with 4-marker budget guard - Parse cache_creation_input_tokens from prompt_tokens_details into Usage.CacheCreationTokens; propagates via existing span metadata writers - Runtime escape hatch: GOCLAW_DISABLE_DASHSCOPE_CACHE=true - Live integration smoke test (build tag integration, env-gated) * chore(providers): polish per PR #1127 review - Use strings.Repeat instead of custom repeat() helper in smoke test - Clarify BuildRequestBodyForTest is test-only, not public API * feat(providers): enable thinking for Qwen 3.7/3.6, observe cache in smoke test Qwen3.7-plus and qwen3.6-plus support deep thinking but were missing from dashscopeThinkingModels, so enable_thinking/thinking_budget was silently skipped. Add both to the whitelist and test. Add qwen3.7-plus to the cache smoke test as cache-optional: Alibaba's context-cache doc does not yet list 3.7/3.6 for explicit cache, and the cache wrap is a safe no-op when unsupported, so a no-cache result is logged rather than failed to avoid a flaky live assertion.
