DeepSeek V4.1 Flash is a reasoning model; 30s timeout caused LiteLLM to abandon in-flight generations (falling back to GPT-OSS) while Tinfoil still completed and billed them. num_retries re-hit Tinfoil up to 3x. Result: Tinfoil billed ~2x the tokens LiteLLM logged. Generous timeout + zero retries stops the silent re-billing.

# LiteLLM config for inference.coop
|
|
# PRODUCTION config: Tinfoil (TEE-protected inference)
|
|
# LiteLLM talks plaintext OpenAI to a local Tinfoil proxy (127.0.0.1:3301),
|
|
# which verifies the enclave attestation and encrypts request/response bodies
|
|
# with EHBP (HPKE) before forwarding to the Tinfoil enclave. Provider key set
|
|
# via environment variable TINFOIL_API_KEY.
|
|
#
|
|
# Pricing (model_info) is per-token, derived from Tinfoil's per-1M rates:
|
|
# deepseek-v4-1-flash: $0.65 in / $1.45 out / $0.13 cached per 1M
|
|
# gpt-oss-120b: $0.15 in / $0.60 out per 1M
|
|
# glm-5-3-flash: $0.40 in / $1.25 out / $0.10 cached per 1M
|
|
# Without these, LiteLLM can't price these custom models, so spend shows $0.00
|
|
# and the team budget cap is not enforced.

# 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.
