Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.01332
Opus 5.5	$0.00032	$0.00533
Sonnet 5.5	$0.00016	$0.00266
Haiku 4.5	$0.00008	$0.00133

Security

Grade A, and why

ads-youtube scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

Generate YouTube-specific findings report with health score

Campaign Types Assessment

Skippable In-Stream (TrueView)

Length: 12s minimum, 15-30s recommended (can be longer)
Bidding: Target CPV or Target CPA
Skip rate benchmark: 65-80% is normal
View rate: ≥15% is good
Evaluate: hook quality in first 5 seconds, CTA card usage

Non-Skippable In-Stream

Length: up to 60s (expanded 2025; previously 15s/20s)
Bidding: Target CPM
Best for: brand awareness, reach campaigns
Evaluate: message completeness, frequency capping, optimal length testing

Bumper Ads

Length: exactly 6s (non-skippable)
Bidding: Target CPM
Best for: reach extension, brand reinforcement
Evaluate: single-message focus, brand visibility throughout

YouTube Shorts Ads

Format: vertical 9:16 (1080x1920)
Length: up to 60s
Best for: younger demographics, mobile-first
Evaluate: native feel (not repurposed horizontal), sound-on optimization

Demand Gen (replaces Discovery)

Placements: YouTube Home Feed, Watch Next, Discover, Gmail
Formats: image + video carousel, product feeds
Evaluate: creative diversity, product feed quality, audience signals

Creative Quality Assessment

Hook Analysis (First 5 Seconds)

Does the video capture attention immediately?
Brand mention within first 5 seconds (recommended for awareness)
Problem/benefit statement upfront (recommended for action campaigns)
No slow intros, title cards, or logos-only openings

Production Quality

Audio quality: clear, professional, background music appropriate
Visual quality: HD minimum (1080p), proper lighting
Subtitles/captions: present (85% of Facebook video watched muted, ~30% on YouTube)
End screen: CTA, subscribe button, related video cards

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
