From 283eee687cec50dfd5fb2fc8d1c13f186223e844 Mon Sep 17 00:00:00 2001 From: David Blanc Brioir Date: Thu, 18 Dec 2025 16:25:02 +0100 Subject: [PATCH] Fix Extended Thinking critical bug and optimize default parameters MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL BUG FIXED: - max_tokens vs thinking_budget_tokens API constraint violation resolved - Changed max_tokens from 4096 to 8192 (App.jsx:4747) - Changed thinking_budget_tokens from 10000 to 6144 (App.jsx:4749) - Updated database default from 10000 to 6144 (server/db/index.js:243) - Result: 8192 > 6144 ✅ API constraint satisfied FRONTEND FIX: - Fixed SSE data mapping for thinking content (App.jsx:5565-5566) - Changed from data.thinking_signature to data.thinking.signature - Changed from fullThinking to data.thinking.content with fallback - ThinkingBlock now displays and persists correctly after streaming CONFIGURATION: - Extended Thinking disabled by default (was true for testing) - Optimal defaults: max_tokens=8192, thinking_budget=6144 (6K) - User-tested configuration validates 6K thinking budget ideal DATABASE UPDATES: - Updated 10+ existing conversations to thinking_budget_tokens=4096 - New conversations default to 6144 tokens - Thinking content now saves and persists correctly TESTING: - ✅ Manual test with Whitehead philosophy question successful - ✅ ThinkingBlock displays with blue UI and brain icon - ✅ Expand/collapse functionality works - ✅ Signature verification indicator shows - ✅ Content persists after streaming and page reload ISSUES COMPLETED: - TEAMPHI-194: ThinkingBlock Component (validated) - TEAMPHI-195: ThinkingBlock Integration (fully functional) - TEAMPHI-199: Streaming Handler (data mapping fixed) Progress: 60% → 80% complete Files modified: - generations/my_project/src/App.jsx (lines 4747-4749, 5565-5566) - generations/my_project/server/db/index.js (line 243) - project_progress.md (comprehensive update) - fix_thinking_budget.py (database migration script) -
