Verdicts par tâche

Routing requests across many modelsOpenRouter l’emporte

OpenRouter's core function is one OpenAI-compatible API across 500+ models and 80+ providers with automatic failover and unified billing; Grok Build CLI exposes only xAI's grok-4.5.

Grok Build CLI has an API, but it is a single model, not a routing layer.

Writing and fixing code in a local repositoryGrok Build CLI l’emporte

OpenRouter is an inference relay — it returns model output but does not orchestrate code changes; Grok Build CLI is a full agentic coding agent.

The Jul 12, 2026 disclosure of undisclosed full-repo uploads (incl .env secrets) makes Grok Build CLI unsafe for secrets-bearing or proprietary repos.

Benchmarking and A/B switching modelsOpenRouter l’emporte

Purpose-built for zero-code model comparison and switching via one endpoint; Grok Build CLI is pinned to grok-4.5 with no cross-provider routing.

OpenRouter's 5.5% platform fee still applies, and it is mid-acquisition by Stripe — announced Aug 19 2026 with a public commitment that routing stays user-driven.

Keeping proprietary code and secrets localOpenRouter l’emporte

OpenRouter relays only the request content you send; Grok Build CLI uploads the entire repository — including unread files and .env secrets — to xAI servers in the background.

Neither is self-hosted: OpenRouter is SaaS, and it is being folded into Stripe. For air-gapped environments neither fits, but OpenRouter does not exfiltrate unread files.

Parallel, multi-worktree agentic refactors (migrations, test backfills)Grok Build CLI l’emporte

Up to 8 parallel sub-agents each in an isolated Git worktree with Plan Mode; OpenRouter has no agent orchestration surface.

Still beta, and single-task accuracy (70.8% SWE-Bench Verified) trails Claude Code (87.6%) and Codex CLI (88.7%).

OpenRouter:Dopé à l’IA

Grok Build CLI:IA native

Core purpose

OpenRouter:Unified model gateway — 500+ models, 80+ providers, one OpenAI-compatible API

Grok Build CLI:Terminal-native agentic coding agent backed by grok-4.5

Different layers — a routing relay vs a coding agent; complementary, not direct substitutes

Pricing

OpenRouter:Freemium; pay-per-token plus a platform fee of 5.5% (Standard) or 8% (Business, which adds EU and US in-region routing); 25+ free models at 50 req/day. BYOK free to $25,000/mo of list-price inference, 5% after

OpenRouter has a free entry tier; Grok Build CLI is a premium subscription

Model access

OpenRouter:500+ models across 80+ providers

Grok Build CLI:Single model — grok-4.5 / grok-build-0.1

OpenRouter far broader; Grok Build CLI is pinned to xAI

AI-native verdict

OpenRouter:powered — stateless per-request relay, no carried-context loop

Grok Build CLI:native — agentic CLI runs the model as core decision engine in a carried-context loop

Grok Build CLI native; OpenRouter powered

Security / data handling

OpenRouter:Relays only the request content you send; standard data-policy controls

Grok Build CLI:Jul 2026 disclosure: uploads full repo (incl .env secrets) to xAI GCS in the background

Grok Build CLI carries a serious undisclosed-upload red flag

Maturity

OpenRouter:Generally available, with paid Standard, Business and Enterprise plans; 500+ models from 80+ providers

Grok Build CLI:Beta — launched May 14, 2026

OpenRouter more mature; Grok Build CLI still beta

Ownership

OpenRouter:Being acquired by Stripe. Announced by both parties Aug 19 2026 at a reported $7B+, subject to customary closing conditions, with OpenRouter stating same mission, name, product and roadmap

Grok Build CLI:Wholly xAI-owned; no ownership change

OpenRouter's ownership question is now settled in public; the neutrality commitment is on the record but the deal is still pre-close
