What is Snorkel AI?

Snorkel AI turns its coding benchmark on Fable 5.2 and finds the terminal failures mostly gone.

Snorkel AI's feed is research and benchmark posts about how agents are evaluated. The newest compares Fable 5.2 with Fable 5.1 on 26 frontier coding tasks: pass@1 rises from 53% to 71%, and the mid-run terminal failures seen in 5.1 nearly disappear. It follows Terminal-Bench 4.1, which hardened verifiers against reward hacking, and a run of early-November posts on reward peeking and energy efficiency.

What is Sudowrite?

Sudowrite's feed has been all writing advice and comparison posts since September.

Every Sudowrite entry since September is a blog post: comparisons against NovelAI and other novel-writing tools, a post on non-English novels, and writing-craft advice on POV slips, romance scenes, stalled drafts and character voice. The last product change in the feed was the June mobile app with the full Muse and Story Bible toolkit.

Snorkel AI vs Sudowrite: editorial side-by-side

5.0

Snorkel AI turns its coding benchmark on Fable 5.2 and finds the terminal failures mostly gone.

◆ Current state

Snorkel AI's feed is research and benchmark posts about how agents are evaluated. The newest compares Fable 5.2 with Fable 5.1 on 26 frontier coding tasks: pass@1 rises from 53% to 71%, and the mid-run terminal failures seen in 5.1 nearly disappear. It follows Terminal-Bench 4.1, which hardened verifiers against reward hacking, and a run of early-November posts on reward peeking and energy efficiency.

◆ Where it's heading

Snorkel is positioning itself as the outside scorer of frontier models: it funds open benchmarks, publishes the methods that keep them honest, and now runs head-to-head model comparisons on its own task sets. The posts sell its evaluation data business by example rather than through product releases.

◆ Prediction

Expect more model-versus-model results on Snorkel task sets as new frontier releases land. The entries show no product or pricing change, so whether this becomes a public leaderboard is unclear.

5.0

Sudowrite's feed has been all writing advice and comparison posts since September.

◆ Current state

Every Sudowrite entry since September is a blog post: comparisons against NovelAI and other novel-writing tools, a post on non-English novels, and writing-craft advice on POV slips, romance scenes, stalled drafts and character voice. The last product change in the feed was the June mobile app with the full Muse and Story Bible toolkit.

◆ Where it's heading

The company is investing in search traffic from fiction writers, with posts aimed at specific craft problems and head-to-head comparisons. The feed carries no product releases, so whether development has slowed or simply isn't being logged here is unclear.

◆ Prediction

More craft and comparison posts are the likeliest next entries; the feed gives no signal of an upcoming product release.
