Vercel

Vercel released @ai-sdk/openai version 3.0.121, a patch that adds SDK support for a model string called 'GPT-6.1 Sol.' OpenAI has not publicly announced or confirmed this model, and no specs, pricing, or benchmarks are available.

Vercel's @ai-sdk/openai package version 2.0.132 quietly adds support for a model identifier called 'GPT-6.1 Sol.' OpenAI has not confirmed the model's existence, specs, or release date.

Vercel released @ai-sdk/xai version 5.0.5, a patch update that adds a model ID for 'grok 4.7' to its xAI provider package. The change lets developers targeting xAI models through the Vercel AI SDK reference the new identifier in their code.

Vercel released @ai-sdk/openai version 4.0.60, a patch update that adds reasoning configuration support referencing 'GPT-6' in the codebase. OpenAI has not announced a GPT-6 model, making this an early SDK-side scaffolding change rather than confirmation of a new release.

Vercel released @ai-sdk/xai version 3.0.119, a patch update that adds model IDs for Grok 4.6 and introduces support for an 'xhigh' reasoning effort parameter. The change lets developers using the Vercel AI SDK target xAI's newer model directly through the existing provider interface.

Vercel released AI SDK version 3.0.106 for xAI integration, adding support for the Grok 4.5 model identifier and expanding input reference capabilities to include video files for reference-to-video generation workflows.

Chinese AI models including DeepSeek and Z.ai have captured over 30% of weekly token usage by U.S. companies on OpenRouter since February 2025, up from 4.5% in the first half of the year. The shift comes as companies seek alternatives 60-90% cheaper than leading models from OpenAI and Anthropic, while Chinese models close the performance gap to within 6-9 months of U.S. frontier systems.
