 # Fallback: if DeepSeek is down, use GPT-OSS
+# NOTE: DeepSeek V4.1 Flash is a reasoning model — generations routinely run
+# longer than 30s. A 30s timeout caused LiteLLM to abandon in-flight DeepSeek
+# requests (falling back to GPT-OSS), while Tinfoil still completed and billed
+# the abandoned generation. num_retries amplified this by re-hitting Tinfoil up
+# to 3x per request. Result: Tinfoil billed ~2x the tokens LiteLLM logged.
+# Fix: a generous timeout so generations complete inside LiteLLM (and get
+# logged), and zero retries so a slow/failed request is never re-billed.
