From c3af128b81c29a0d02c7630013838c0491599aa8 Mon Sep 17 00:00:00 2001 From: renjianbo <263303411@qq.com> Date: Mon, 27 Jul 2026 00:43:17 +0800 Subject: [PATCH] fix: moonshot temperature=1, 20MB upload limit, file input FileList fix, rate limiter off - workflow_integration: force temperature=1.0 for moonshot provider (Kimi K3 reasoning models reject other values), both agent node and orchestrator node - config: LOCAL_FILE_WRITE_MAX_BYTES 2MB -> 20MB (image uploads) - main: temporarily disable RateLimiterMiddleware - useFileUpload: copy FileList before resetting input (Chromium clears reference) - AgentChat/AgentChatPreview: attach button via ChatInputArea ref --- backend/app/agent_runtime/workflow_integration.py | 13 +++++++++++-- backend/app/core/config.py | 2 +- backend/app/main.py | 3 ++- frontend/src/components/AgentChatPreview.vue | 5 ++++- frontend/src/composables/useFileUpload.ts | 10 ++++++---- frontend/src/views/AgentChat.vue | 3 ++- 6 files changed, 26 insertions(+), 10 deletions(-) diff --git a/backend/app/agent_runtime/workflow_integration.py b/backend/app/agent_runtime/workflow_integration.py index f2e24a9..4464a5d 100644 --- a/backend/app/agent_runtime/workflow_integration.py +++ b/backend/app/agent_runtime/workflow_integration.py @@ -64,10 +64,15 @@ async def run_agent_node( formatted_prompt = raw_prompt # 3. 构建 Agent 配置 + _provider = node_data.get("provider", "openai") + temperature = float(node_data.get("temperature", 0.7)) + # Kimi K3 等推理模型强制要求 temperature=1 + if _provider == "moonshot": + temperature = 1.0 llm_config = AgentLLMConfig( -
