Promptfoo vs Snorkel AI
A side-by-side editorial comparison of Promptfoo and Snorkel AI — release velocity, themes, recent moves, and the top alternatives to consider.
Promptfoo vs Snorkel AI: at a glance
What is Promptfoo?
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.
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.

Promptfoo
5.0AI-ASSISTANTS
Promptfoo's feed has gone quiet except for small fixes to its code-scan action.
◆ Current state
The newest entries are code-scan GitHub Action patches: 0.2.1 updates type definitions and 0.2.2 mints the OIDC token after the CLI installs. The main evaluator's last visible release, 0.121.20 in July, added Claude Opus 5, Kimi K3 and websocket URL templating, following a run of releases that tracked each new frontier model.
◆ Where it's heading
The evaluator's rhythm is provider coverage plus red-team strategies, and the code-scan action is maintained on its own track. The feed shows no evaluator release since July, which may be a feed gap rather than a pause.
◆ Prediction
If the evaluator is still shipping, the next visible entry will likely add the latest frontier models; the feed doesn't show whether it stopped.
Snorkel AI
5.0AI-ASSISTANTS
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.
