* ✳️ feat: Claude Opus 5 Support - Add claude-opus-5 to Anthropic/Bedrock model lists, token maps, and pricing - Extend requiresExplicitThinkingDisabled to Opus 5 so thinking-off sticks - Clamp xhigh/max effort to high when thinking is disabled (Opus 5 400) * 🪣 fix: Use Bedrock Inference Profiles and Add Vertex Opus Models Bare `anthropic.` Claude 4+ IDs are not invocable on-demand via Converse: Bedrock rejects them with "Retry your request with the ID or ARN of an inference profile that contains this model." Verified live against us-west-2 for Fable 5, Opus 5, Opus 4.8, Sonnet 5, Sonnet 4.6, Opus 4.6, Sonnet 4.5, Haiku 4.5, and Opus 4.1. Switch those defaults to the `global.` profile (no regional pricing premium); Opus 4.1 has no global profile, so it uses `us.`. Also add the modern Opus family to the Vertex defaults. `loadEndpoints` swaps the shared Anthropic list for the Vertex model names, so Opus was invisible to every Vertex deployment that did not enumerate models by hand. * 📋 chore: Cover Opus 5 Gaps From PR #14420 Picks up items from the parallel community PR by @jona7o: - Add claude-opus-5 to the librechat.example.yaml Vertex example (both the legacy array and the deploymentName map), which already lists Fable 5 and Opus 4.8 - Mention Opus 5 in the configureReasoning doc comment, and note that its early return is why the effort cap is enforced by the caller - Assert Opus 5 carries no long-context premium pricing - Cover the Sonnet 5 negative case for the effort cap, and the persisted disabled-object round-trip carrying an effort * 🌍 docs: Warn That Vertex Regional Endpoints Reject Modern Models Anthropic serves Sonnet 4.6 and earlier on specific Vertex regional endpoints; newer models (Opus 4.7+, Opus 5, Sonnet 5, Fable 5) require `global` or a multi-region location and 404 on a specific region. The `us-east5` default therefore cannot serve the Opus models added here, nor the Sonnet 5 entry that predates this branch. Documents the constraint at all three places an operator sets the region, and at the fallback itself. Leaves the default unchanged: switching it to `global` would silently alter data routing and residency for existing deployments, which is a separate call. * 🩹 fix: Restore PDF Exemption for Undated IDs and Gate Vertex Defaults Two issues raised in review: - BEDROCK_CLAUDE_4_PLUS_RE required a `-` after the major version, so it matched `claude-opus-4-8` but not undated IDs like `claude-opus-5`. Those models silently lost the Claude 4+ PDF exemption and fell back to the 4.5 MB limit. Sonnet 5 and Fable 5 were already affected before this branch; Fable/Mythos were also missing from the family alternation. - The Vertex defaults advertised models that only `global` and the multi-region locations serve, so a default `us-east5` deployment listed Opus choices that 404 on first request. Filter the built-in defaults by configured region instead of changing the region default, which would alter data routing for existing deployments. An explicit `vertex.models` list is the operator's choice and is never pruned. * 🧩 fix: Match Bare Claude IDs in the Bedrock PDF Exemption An application inference profile maps a LibreChat model ID with no `anthropic.` segment, so `claude-opus-5` failed the Claude 4+ check and fell back to the 4.5 MB PDF limit. Make the prefix optional and accept both segment orders, mirroring BEDROCK_CLAUDE_4PLUS_THINKING in librechat-data-provider, which matches on the family token for exactly this reason. Only reached for the Bedrock provider, so the looser prefix cannot leak into other endpoints. Verified Claude 3.x, Nova, Llama, Cohere, and Mistral IDs still fall through to the default limit. * 🧹 fix: Drop Retired Claude 3.5 Models From Bedrock Defaults The three Claude 3.5 entries reached end of life at AWS and return ResourceNotFoundException in every prefix form (bare, `us.`, `global.` — verified live against us-west-2), so selecting one was a hard error. Their modern equivalents are already in the list: Sonnet 5 / Sonnet 4.6 supersede the 3.5 Sonnets, and Haiku 4.5 supersedes 3.5 Haiku. Every remaining Anthropic default is now live-verified invocable. `.env.example` swaps its retired example ID for Haiku 4.5. * 🔒 refactor: Narrow Effort-Clamp Types Instead of Asserting Both clamp sites reached into loosely-typed containers with assertions: llm.ts used an `as unknown as { type?: string }` double assertion to read the thinking type, and the Bedrock parser cast `output_config` to `{ effort?: unknown }` before confirming it was an object. CLAUDE.md's type-safety rules call for narrowing over both. Adds `isThinkingDisabled` and `clampOutputConfigEffort` to librechat-data-provider, using `in`-operator narrowing and a type predicate so no assertion is needed at all. Both call sites now share one implementation rather than duplicating the clamp. Behavior is unchanged; existing clamp tests cover it. |
