Background

DeepSeek has swapped the engine under its cheapest model without touching the price. V4.1-Flash-1017, a new checkpoint of the Flash model released in September, is now live on the website, the app and the API, where the name deepseek-flash serves it at the same off-peak rates of $0.15 per million input tokens and $0.60 per million output. DeepSeek calls the change a Pareto improvement in performance and cost: in its own table the checkpoint beats its predecessor on all eleven reported benchmarks, lifting DeepSWE v1.1 to 77.0, above the 74.0 listed for Claude Opus 5 and the 73.0 for GPT-5.6 Sol, and Terminal-Bench 4.0 to 42.3 from 31.2, while finishing tasks faster and writing shorter outputs. Raw reasoning still trails the leaders, with Humanity's Last Exam at 42.6 against 56.3 for Opus 5 in the same table. The checkpoint was tuned with reinforcement learning and self-feedback for end-to-end project work, from game creation to 3D modelling, and its weights are published on Hugging Face and ModelScope. The same announcement opens DeepSeek's own Search and Fetch APIs to everyone, at $0.75 per 1,000 calls per endpoint, powered by its in-house search engine. Calls routed through server-side tools in DeepSeek Harness, Claude Code and Codex stay free for now; billing starts on October 31.

This market exists because launch announcements are easy to make and hard to grade. Press releases describe what a company intends to ship; they rarely come back later to say whether it shipped. AI Rank Bank pulls one checkable sentence out of the coverage — the sentence above — gives it a date, and lets readers price it in public. The launch itself stays with its publisher; what lives here is the claim, the crowd's call, and eventually the receipt.

How this claim is judged

Judging criteria, fixed when the market opened: Delivered if, at the check time, DeepSeek's documentation shows billing for Search and Fetch in force from October 31, 2026, 16:00 UTC (November 1, 00:00 Beijing time) at $0.75 per 1,000 successful calls per endpoint, ending the free server-side arrangement through DeepSeek Harness, Claude Code and Codex on the announced schedule. Billing having started materially earlier than announced, the free period having been extended past that date as a permanent arrangement, or the endpoints having been withdrawn does not count.

The source of record is the publisher's own page linked above. A claim about a company's product is judged against that company's public output — its product pages, documentation, changelogs and official posts — not against rumors or third-party summaries. Only yes-or-no outcomes count: partial credit is not a verdict, and a claim that needs a paragraph of excuses has already answered itself.

How readers called it

1 reader called this claim. 100% said it would deliver.

1 Will deliver · 0 Won't ship

Points reward being right against the crowd. A correct call pays 100 × (1 − the share of readers who agreed with you when you placed it), with a floor of 10: side with a 90% consensus and a win pays 10, stand alone and a win pays up to 100. Wrong calls pay nothing. The price is locked in when the call is placed, so early readers are paid for judging before the crowd forms, not for copying it.

How readers split

Share of readers saying “will deliver”: opened at 100%, now at 100%. 4 snapshots on record since 2026-10-17 — a snapshot lands whenever a call is placed, and at least hourly while the market is open.

Verdict

No verdict yet. This claim is checked on 2026-11-01 07:00 Eastern Time (12:00 UTC) against the source of record below. When the check happens, one of three stamps lands on this page permanently: delivered if the claim came true as stated, busted if it did not, or unproven if the date passes without public evidence either way. Unproven claims pay no points and do not count against any reader's hit rate.

About this market

AI Rank Bank is an AI news front page with a memory. Every launch on the homepage carries one claim like this one, with a check date. Readers call claims with points, build a public record, and climb the leaderboard. Companies build a record too: every settled claim lands on the company's bank page, where its delivery rate is simple arithmetic that nobody gets to edit afterwards. There is no money in the market — points buy bragging rights only, which keeps the incentives pointed at being right.
