DeepSeek V4 Flash on Letta is no longer free: at the 2026-10-23 recheck the model catalogue lists it under the credit-billed tier, and a live free-plan probe was refused with "minimum $1 in credits is required" (the same error as its sister lane on 2026-10-17); a letta/echo control on the same account passed, so the refusal is model-specific → end date Oct 23

Letta's free window for DeepSeek V4.1 Flash ended 2026-10-17: model requests now consume credits, and a free account with a $0.00 balance was refused with "minimum $1 in credits is required"; the pricing docs say model requests consume credits at a rate depending on model API pricing, and the per-model price page needs a login → end date Oct 17

OpenRouter added deepseek/deepseek-v4.1-flash-1017 (created 2026-10-17T08:27:04Z): DeepSeek first-party endpoint only, no :free variant; DeepSeek upgraded V4.1 Flash in place to the 1017 snapshot with the API name (deepseek-flash) and pricing unchanged, so channels serving the unversioned deepseek-v4.1-flash id are on 1017 while their labels still say the old name
