Jev model reports for GPT, Claude, Gemini, Grok, Kimi, DeepSeek, Muse Wonder and images
Eight reports bring together X posts, follow-ups, and project documentation. Seven cover language-model families. The image report covers OCR, filenames, pixel-color questions, a separate drawing model, and Jev Day native image input behind TypeSafe-Danger-Zone-Images. The Muse Wonder report covers skills that install Jev inside Muse and Muse Code. The cited Muse workflows date from 19 September to 1 October 2026 and name Muse or Muse Code. The GPT report includes ClickHouse’s 0.951 nDCG@10 warehouse table ranking, Sanity’s 0.5-second docs agent with gpt-oss-120b, Artificial Analysis’s Decision Index next to GPT-6 Luna, 4,500 ALFWorld and AndroidWorld runs that swap gpt-5.6-luna action selection for jev-1.13.0, and Arize’s bake-off against OpenAI Decisions. The Claude report includes Takuma Yoshida’s 100 fictional return emails against Haiku 5.5, Haiku 5.5 on Decision Index, and a Zenn check of Haiku, Sonnet and Opus 5.5 on MASSIVE, chABSA and JNLI. The Gemini report includes Salesgear’s 203-thread triage against Gemini 3.8 Flash, TypeSafe’s Jack & Jill screen against Gemini 3.1 Flash Lite, and Google’s Argon announcement, which names no Jev score. The write-ups separate runtime handoffs, side-by-side tests, and cases where a language model only helped write the code. The Jevtember page covers Vercel’s September AI Gateway adoption figures. The Jev Day 2026 hub covers jev-1.14.0, Box, and 262k context. The Composio Firewall page covers session hooks that evaluate tool calls with Jev.
Jev + GPT / Codex
ClickHouse ranks warehouse tables with Jev at 0.951 nDCG@10 in about 0.4 seconds. Sanity’s docs agent still answers with openai/gpt-oss-120b after Jev picks the knowledge-base entry.
Jev + Claude
Takuma Yoshida scores jev-1.14.0 at 78 of 100 fictional return emails against 91 for Claude Haiku 5.5. Haiku 5.5 (Low) scores 61 on Artificial Analysis’s Decision Index, 3 points above Jev 1.13.
Jev + Gemini
Salesgear’s 203-thread test scores Gemini 3.8 Flash at 199 of 203 and Jev 1.13.0 at 193. TypeSafe’s Jack & Jill case study reports replacing Gemini 3.1 Flash Lite on an initial candidate screen.
Jev + Grok
A 1,000-post selection workflow and a separate action-router setup, with source links and no inferred speed or cost claims.
Jev + Kimi
A measured email handoff to Kimi K3, a SemEval chart against Kimi-K2 Thinking, one snapshot where a Kimi K3 alias returned 139 valid answers of 231, and a hook log that named kimi-k3 once.
Jev + DeepSeek
Vals prices DeepSeek V4.1 Flash at $0.55 per 1,000 claim-verification cases with probabilities, against $0.02 for Jev 1.13.0. Arena still compares its Jev Router with DeepSeek V4.1 Flash (Max).
Jev + Muse Wonder
Meta released Muse Wonder on 12 October 2026. The cited Muse workflows install Jev as a typed judge inside Muse or Muse Code. Those posts and READMEs date from 19 September to 1 October 2026 and name Muse or Muse Code.
Jev + Images
Hosted Jev takes text by default. Image files need TypeSafe-Danger-Zone-Images on jev-1.13.0 and jev-1.14.0. The reports below also cover OCR first, filenames, pixel-color questions, and a drawing step gated by Jev.
Compare measurements within the same task and dataset. The benchmark reports preserve those boundaries; the source notes record what each author actually reported.
