No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No changeset needed — CI-only change, no package code affected.

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No changeset needed — CI-only change, no package code affected.

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

79f0d4bc7d1da1a111c6214933c8b559422dc5d3

[TooTallNate]

Summary

• Updates the backport workflow's default AI model from anthropic/claude-opus-4.7 to anthropic/claude-fable-5 (via Vercel AI Gateway)
• The workflow_dispatchmodel input override is unchanged

No changeset needed — CI-only change, no package code affected.

Column Definitions

• Workflow Time: Runtime reported by workflow (completedAt - createdAt) - primary metric
• TTFB: Time to First Byte - time from workflow start until first stream byte received (stream benchmarks only)
• Slurp: Time from first byte to complete stream consumption (stream benchmarks only)
• Wall Time: Total testbench time (trigger workflow + poll for result)
• Overhead: Testbench overhead (Wall Time - Workflow Time)
• Samples: Number of benchmark iterations run
• vs Fastest: How much slower compared to the fastest configuration for this benchmark

No backport to stable for 79f0d4b (AI decision).

This commit only modifies .github/workflows/backport.yml, which I verified does not exist on stable (git ls-tree origin/stable returns nothing for it). The backport workflow runs exclusively from main (triggered on pushes to main), so cherry-picking this change to stable would create a file that serves no purpose there.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
