   Thanks for the detailed report. I reproduced this on @opencode/[email protected], and it still happens on the latest dev (fa1260d6).

   I set up a simulated provider with three paid models ("OpenAI: GPT Luna Latest", "OpenAI: GPT-5.6 Luna", "Poolside: Laguna S 2.1") and two free ones ("InclusionAI: Ling-3.0-Flash (free)", "InclusionAI: Ling-3.0-Flash-Fin (free)"). Then I opened /models and typed luna. The two InclusionAI models, which only match through the scattered letters in "incLUsioNAi", come first, and Ling-3.0-Flash is pre-selected. The models that actually contain "Luna" come after them.

   On v2 the release-date sort you traced to #33558 has since been removed (#57151). However, the search results still go through sortModelOptions(…, false), which now puts free models first. That still overrides fuzzysort's relevance order. The recording and screenshots below show it, and the script below reproduces it.

   Related: #50532 (your earlier fix, closed because it targeted v1), #33558 and #47183 (where search results started being re-sorted), #57151 (removed the release-date part).

   Reproduction script (drive.ts)

   // Repro for anomalyco/opencode#50531: model picker search lets a free scattered-letter
   // fuzzy match outrank (and be pre-selected over) models whose names contain the query exactly.
   import { Effect } from "effect"
   import { OpenCodeDriver } from "opencode-drive"
   
   const paid = { input: 1, output: 2 }
   const free = { input: 0, output: 0 }
   const model = (name: string, cost: { input: number; output: number }, releaseDate: string) => ({
     name,
     cost,
     releaseDate,
     capabilities: { tools: true, input: ["text"], output: ["text"] },

   export default OpenCodeDriver.use(
     {
       ...(process.env.OC_DEV ? { opencode: { dev: process.env.OC_DEV } } : {}),
       tui: { recording: true, keypressOverlay: true },
       config: {

               "ling-3.0-flash-fin:free": model("InclusionAI: Ling-3.0-Flash-Fin (free)", free, "2025-01-01"),
               "ling-3.0-flash:free": model("InclusionAI: Ling-3.0-Flash (free)", free, "2025-01-01"),
             },
           },
         },
       },
     },
     ({ ui }) =>
       Effect.gen(function* () {
         yield* ui.screenshot("home")
         yield* ui.type("/models")
         yield* Effect.sleep("500 millis")
         yield* ui.enter()
         yield* ui.waitFor("GPT Luna Latest")
         yield* ui.screenshot("picker-open")
         yield* ui.type("luna")
         yield* Effect.sleep("1 second")
         yield* ui.screenshot("search-luna")
         const frame = yield* ui.capture()
         yield* Effect.log(JSON.stringify(frame).slice(0, 200))
         yield* Effect.sleep("1 second")
       }),
   )

   Run it with opencode-drive: opencode-drive run ./drive.ts. It drives opencode from your PATH; set OC_DEV to the path of an OpenCode checkout to run that from source instead.
