Source Summary

Vercel AI Gateway now offers **Grok 4.7** with a **500K-token context window** and low, medium, high, or xhigh reasoning. The same model ID works across AI SDK, Chat Completions, fx, Cursor, Codex, Amp, OpenCode, and eve.

Practical Implication

Builders can vary reasoning depth for latency-sensitive versus deeper tasks while keeping one Gateway model ID. Requests also participate in Gateway logs, reporting, budgets, routing, retries, and failover.

The **40% discount ends September 27**. The material provides no benchmark, latency, or workload-cost results, so the promotion should not substitute for evaluation.

Connected Context · Feed7 Judgment

Grok 4.7 adds another adjustable-reasoning coding route that can be reused across several agent clients under one gateway ID. Against the crowded candidate set, neither its 500K context nor its temporary discount establishes a preferred default; representative tests must determine whether reasoning level, latency, quality, and post-promotion cost fit the workload.

Introducing Grok 4.6Grok 4.6 is the closest supplied Grok comparison point, but its reported self-testing and visual behavior cannot be assumed for 4.7 without matched trials.Gemini 3.8 Flash now available on AI GatewayGemini offers a larger context window and multimodal capabilities, while both carry temporary discounts that can distort long-term cost comparisons.GLM 5.3 now available on AI GatewayGLM 5.3 supplies a 1M-context repository-scale alternative, reinforcing that Grok’s smaller context and selectable reasoning should be compared on actual engineering tasks rather than capacity claims.GPT 5.6 Sol, Luna, and Terra now available on AI GatewayGPT 5.6 provides separate flagship, balanced, and lower-cost routes, contrasting with Grok 4.7’s single model ID whose reasoning depth is varied per request.
