From 6120561a6e78f770ae40def410ea22d29259a8af Mon Sep 17 00:00:00 2001 From: herjarsa Date: Fri, 17 Jul 2026 15:49:45 +0200 Subject: [PATCH 1/2] fix(stream-readiness): bump timeout for heavy Claude-format reasoning replicas MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Third-party Claude-format replicas (Minimax M2.7/M3, ZAI, bailian, agentrouter, wafer, …) inherit Anthropic's stream shape but their reasoning warm-ups routinely exceed the default 80s readiness window — the STREAM_READINESS_TIMEOUT fires before the upstream emits its first non-ping SSE event, surfacing the request as a stalled task to clients like OpenChamber / Claude Code and demanding manual continuation on every long-running task. Mirror the codex_gpt_5_5_high_reasoning +30s bump on every provider whose registry entry has format === 'claude' (excluding first-party claude/anthropic which have stable cold starts). The registry is the single source of truth, so newly-registered replicas inherit the bump without code changes. Stays within the existing maxTimeoutMs cap so a single env knob still bounds the readiness window overall. Tests: - covers Minimax M3, ZAI, official claude/anthropic (no bump), OpenAI (no bump), unknown providers (no false positives), and the maxTimeoutMs cap with the new bump stacked against large payloads. - all 17 stream-readiness-policy tests pass (10 existing + 7 new). - existing 16 stream-readiness + 11 combo-stream-readiness-fallback tests still pass (no regressions). --- open-sse/utils/streamReadinessPolicy.ts | 33 +++++++ tests/unit/stream-readiness-policy.test.ts | 105 +++++++++++++++++++++ 2 files changed, 138 insertions(+) diff --git a/open-sse/utils/streamReadinessPolicy.ts b/open-sse/utils/streamReadinessPolicy.ts index 56e58a03b92..9dcf631345e 100644 --- a/open-sse/utils/streamReadinessPolicy.ts +++ b/open-sse/utils/streamReadinessPolicy.ts @@ -1,3 +1,5 @@ +import { getRegistryEntry } from "../config/providerRegistry.ts"; + type StreamReadinessBody = Record | null | undefined; export type StreamReadinessPolicyInput = { @@ -34,6 +36,27 @@ function estimateBodyChars(body: StreamReadinessBody): number { return 0; } } +// Official Anthropic endpoints — they have stable/quick cold starts, so no +// extra readiness bump is needed. +const OFFICIAL_CLAUDE_FORMAT_PROVIDERS = new Set(["claude", "anthropic"]); + +/** + * Third-party Claude-format providers (replicas like Minimax, ZAI, + * bailian-coding-plan, agentrouter, wafer) inherit Anthropic's stream shape + * but their reasoning warm-ups run significantly longer than first-party + * claude/anthropic — enough that a default 80s readiness window 504s before + * the upstream emits its first non-ping event.
