Root cause found in container: camel-ai v0.2.78 openai_model.py L117 reads
os.environ.get('OPENAI_API_BASE_URL') — NOT OPENAI_BASE_URL.
Fix: Set BOTH env vars (OPENAI_BASE_URL for OpenAI SDK + OPENAI_API_BASE_URL for camel-ai).
Keep model_config_dict={} empty so nothing spreads to create().
Also fix Step 2 Thai truncation: \w regex doesn't match Thai tone marks (Mn category).
Use explicit Unicode range \u0E00-\u0E7F instead.
