Model Availability Matrix
Which models --model accepts, whether each is available to corefix code, corefix web, or both, and which rotation pool it belongs to. See Supported Models for how automatic selection and BYOK work, and Model Pricing for rates.

OpenCode (CodeFix)
Whether a model can be used for --patch / AI autofix generation, which runs through OpenCode (see How CoreFix Talks to Models), is separate from the table above. bedrock:runtime:claude-haiku-4.5 is the one exception — OpenCode can't use AWS Bedrock models, so it isn't available for CodeFix even though it's a supported model for AI enrichment (which always goes through CoreFix's endpoint, not OpenCode). Every other model in the table works for both.
Rotation Pool is which pool CoreFix picks from when auto-selecting a model (no --model passed): Standard when your organization has no CoreFix credits available, Premium when it does — regardless of plan name; a Free-plan account with purchased pay-as-you-go credits gets Premium-pool selection too. See How Model Selection Works.
Open Source Projects and Paid Plans show what this looks like in the common case: an open source project with no purchased credits only ever gets Standard-pool models — auto-selected, and any explicit --model pin is ignored, same as How Model Selection Works describes for "no credits available". A Pro or Teams plan has credits by default, so all ten models — both pools — are available to it, whether auto-selected (Premium) or pinned explicitly with --model (either pool).
All ten models above are available:
- Via BYOK — pass
--openai-api-keytogether with--model, provided the model is one of the ten above. See How CoreFix Talks to Models. - By pinning explicitly — with credits available, pass
--modelto use any of the ten directly (from either pool), no BYOK required, billed in CoreFix credits.
Without credits and without BYOK, --model is ignored and a model is selected automatically from the Standard pool.
