Gemini 3.7 Flash just broke for minimal reasoning, and the fix that landed overnight says more about the AI SDK's trajectory than any feature release.

The AI SDK fixed a production blocker where Gemini 3.7 Flash rejected 'minimal' and 'none' reasoning values with HTTP 400, forcing the provider to use 'low' instead [1]. That landed in a flurry of patches, including WorkflowAgent surfacing model stream errors without retries [2] and finally making maxRetries control model-call attempts [3]. Meanwhile, Eve reworked onboarding reliability with unified project discovery [5] and safe agent directory initialization [6], while making glob and grep tools opt-in to slim the default model-facing toolkit [4]. Next.js shipped canary 16.3.1-canary.22 with a 32-bit usize fix and test fixture restorations, but the real story is a CI fix ensuring canary releases no longer lag stable after backports [7]. Chat tightened attachment downloads to Google's media API, dropping the unsupported downloadUri fallback [8], and isolated queue dispatch by thread to prevent cross-thread state bleed [9]. The twilio adapter also patched a credentials leak to untrusted media origins [10].
