## Thinking Path > - Paperclip orchestrates AI agents through pluggable local adapters; codex_local wraps OpenAI's `codex` CLI. > - The codex_local adapter declares a hard-coded `DEFAULT_CODEX_LOCAL_MODEL = "gpt-5.3-codex"` and multiple Paperclip consumers (UI build-config, server route, OnboardingWizard, NewAgent form, AgentConfigForm) fall back to it when the operator doesn't pick a model. > - That model — and every `*-codex` model plus the older `gpt-5/5.1/5.2` lines — is API-key-only. Codex CLI rejects them on ChatGPT subscription auth with "The 'gpt-5.3-codex' model is not supported when using Codex with a ChatGPT account." > - Every codex_local agent created through the default onboarding path inherits this pin and breaks on its first heartbeat for any user authed via `codex login` (ChatGPT). > - claude_local already takes the right shape: its build-config only sets `adapterConfig.model` when the operator actually picked one, and falls through to whatever default `claude` CLI uses. > - Codex CLI's own default is auth-mode-aware. ChatGPT-subscription accounts get `gpt-5.5`; API-key accounts get the codex-tuned default. A Paperclip-side pin masks this and downgrades whichever group it wasn't built for. > - This PR makes codex_local match claude_local's shape: omit `adapterConfig.model` when the user picks "default," and let the CLI choose. Subscription users stop breaking; API-key users stop getting downgraded. > - The benefit is auth-mode-correct defaults with no Paperclip-side hard pin, plus future-proofing: when OpenAI bumps the CLI default we inherit it for free. ## What Changed - `packages/adapters/codex-local/src/ui/build-config.ts` — only set `adapterConfig.model` when the operator picked one (parity with `packages/adapters/claude-local/src/ui/build-config.ts`). - `server/src/routes/agents.ts` — drop the codex_local-specific `next.model = DEFAULT_CODEX_LOCAL_MODEL` fallback in `applyCreateDefaultsByAdapterType`. Bypass-sandbox default is left in place (security posture, not a model choice). - `ui/src/pages/NewAgent.tsx`, `ui/src/components/AgentConfigForm.tsx`, `ui/src/components/OnboardingWizard.tsx` — stop pre-populating the model field with `DEFAULT_CODEX_LOCAL_MODEL` when the user selects the Codex adapter. Other adapters' defaults (gemini_local, cursor, opencode_local) are unchanged. - `DEFAULT_CODEX_LOCAL_MODEL` is preserved as an exported constant for downstream consumers / plugin authors who want to opt in to a pin; we just stop forcing it on operators who didn't ask for one. - Test: assert `buildCodexLocalConfig` omits `model` when input is blank. ## Verification - `pnpm exec vitest run packages/adapters/codex-local/src/ui/build-config.test.ts packages/adapters/codex-local/src/server/codex-args.test.ts server/src/__tests__/adapter-registry.test.ts server/src/__tests__/heartbeat-model-profile.test.ts server/src/__tests__/agent-permissions-routes.test.ts` → 74/74 passing - `pnpm exec vitest run ui/src/lib/duplicate-agent-payload.test.ts ui/src/lib/acpx-model-filter.test.ts` → passing - `pnpm tsc --noEmit -p .` → clean - Live: I separately verified live during initial investigation that on ChatGPT-subscription auth, `gpt-5.3-codex` is rejected and `gpt-5.5` is what Codex CLI picks by default. Omitting model lets the CLI handle that. ## Risks - Telemetry: any sink that reads `adapterConfig.model` for cost attribution will now see the empty/omitted case more often. The CLI emits the actually-used model in its event stream; downstream telemetry should already read from there for accuracy, but worth a check. - Operator UX: "default" now means "whatever the CLI picks" instead of a Paperclip-known model. The selectable catalog still includes `gpt-5.5`, `gpt-5.4`, `gpt-5.3-codex`, etc. for operators who want to pin explicitly. - Existing agents are unaffected — their `adapterConfig.model` is already set; this only changes the *new-agent* default flow. ## Related work - Depends on: an open catalog-add PR adding `gpt-5.5` to the selectable model list and to `CODEX_LOCAL_FAST_MODE_SUPPORTED_MODELS`. Operators who want to switch to `gpt-5.5` explicitly need that PR merged first; this PR is the structural change that makes "default" mean "let the CLI choose." - Closes #5371 — codex_local default model selection persists `gpt-5.3-codex` instead of adapter default (this PR is the exact fix #5371 proposes). - Related: #5132 (opencode-local: hire-time default model fails on ChatGPT-OAuth accounts) — same problem shape on a sibling adapter; not fixed here but worth tracking for a parallel. - Related: #5939 (codex_local adapter hardcodes `gpt-5.3-codex-spark` validation, fails on ChatGPT OAuth accounts regardless of configured model) — separate validation-path bug; not fixed here. ## Model Used Claude (Sonnet-class), running inside Paperclip as a claude_local executor. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] If this change affects the UI, I have included before/after screenshots - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge Co-authored-by: Paperclip <noreply@paperclip.ing>
