📝 Walkthrough

Summary by CodeRabbit

• New Features

  • Added image-generation pricing controls for 1024×1536 and 1536×1024 dimensions, including standard, low, medium, and high quality tiers.
  • Added support for these pricing overrides in the API, catalog, database, and custom-pricing interface.
  • Improved Redis vector-search filtering for values containing special characters.

• Bug Fixes

  • Improved response decoding for gzip, Brotli, deflate, and Zstandard encodings.
  • Prevented unsupported compression formats and caller content types from being forwarded.
  • Corrected absolute time-range filtering in workspace logs.

• Security

  • Sensitive request headers are now redacted in traces and external observability data.

• Infrastructure

  • Increased proxy write timeout to 15 minutes.

Walkthrough

The PR adds orientation- and quality-specific image pricing across calculation, persistence, schemas, documentation, and UI. It expands response encoding support, redacts sensitive headers, improves Redis search escaping, and updates proxy timeout and log filtering.

Changes

Image pricing

Layer / File(s)	Summary
Pricing contracts and persistence framework/configstore/..., framework/modelcatalog/datasheet/types.go, framework/configstore/tables/modelpricing.go, docs/openapi/..., docs/architecture/..., .github/workflows/scripts/run-migration-tests.sh	Adds fourteen nullable image-pricing columns, migration and rollback support, database synchronization, conversions, API schemas, documentation, and migration coverage.
Image cost selection and overrides framework/modelcatalog/datasheet/cost.go, framework/modelcatalog/datasheet/cost_test.go, framework/modelcatalog/datasheet/overrides.go, framework/modelcatalog/datasheet/overrides_test.go	Parses image dimensions separately and applies size-and-quality, quality-only, size-only, and flat-rate fallbacks. Tests cover orientations, quality levels, precedence, multiplication, parsing, and overrides.
Pricing management surfaces docs/providers/custom-pricing.mdx, ui/lib/types/governance.ts, ui/app/workspace/custom-pricing/overrides/*	Documents and exposes the new dimension and quality pricing fields in governance types and custom-pricing controls.

Response encoding

Layer / File(s)	Summary
Encoding filtering and decoding core/providers/utils/utils.go, core/providers/utils/utils_test.go	Filters buffered and streaming Accept-Encoding values and decodes stacked identity, gzip, x-gzip, deflate, Brotli, and zstd responses with explicit errors.
Anthropic streaming integration core/providers/anthropic/anthropic.go, core/providers/anthropic/passthroughheaders_test.go	Routes streaming chat and Responses requests through the streaming-specific passthrough-header helper. Tests cover supported, unsupported, wildcard, and fallback encodings.

Header redaction

Layer / File(s)	Summary
Sensitive-header detection and redaction core/schemas/trace.go, core/schemas/headers.go, core/schemas/*_test.go	Recognizes JWT, assertion, Cloudflare Access, and AWS ALB OIDC headers and replaces sensitive values while preserving keys and nil handling.
Observability header consumers framework/tracing/tracer.go, plugins/maxim/main.go	Redacts filtered request headers before trace storage and Maxim tag forwarding.

Redis search escaping

Layer / File(s)	Summary
Search-value escaping and validation framework/vectorstore/redis.go, framework/vectorstore/redis_test.go	Escapes non-alphanumeric ASCII search values while preserving underscores and non-ASCII bytes. Tests cover query operators and vector searches with punctuation-containing model names.

Runtime support

Layer / File(s)	Summary
Proxy and log filter updates pulse.yaml, ui/app/workspace/logs/page.tsx	Sets the bifrost proxy write timeout to 900 seconds and corrects absolute log time-range filter construction.

Replace the fixed wait with a condition-based wait.

Line 1518 waits for 500 ms but does not verify that RediSearch indexed either document. If indexing takes longer, the next assertions can fail intermittently. Poll the model queries with a bounded timeout until each expected document is visible.

As per coding guidelines, “deterministic tests” are required.

The current cases also match the explicit cf-access- and x-amzn-oidc- prefixes. Add non-prefixed, non-token-suffixed names such as x-custom-jwt-header and x-custom-assertion-header to prove both substring branches redact values.

Limit decoded response size.

Lines 2073, 2084, 2092, and 2103 read decompressed data without a byte limit. A compressed upstream response can exhaust process memory. Read each decoded stream through one shared bounded reader and return an error when the decoded limit is exceeded.

As per coding guidelines, “enforce timeouts and size limits.” As per path instructions, core/** requires “bounded resource usage.”

Align the Maxim module with the core API before calling this helper.

plugins/maxim/go.mod resolves github.com/maximhq/bifrost/core to v1.7.10, which does not export schemas.RedactSensitiveHeaders. Update the dependency or add a module replacement, then verify that the Maxim module builds.

🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Validate the parsed metadata filter shape.

JSON.parse can return an array, primitive, or null without throwing. A malformed URL value can therefore bypass the catch block and violate the LogFilters.metadata_filters contract. Accept only a non-null object with string values; otherwise return undefined.

Proposed fix

 					try {
-						return JSON.parse(urlState.metadata_filters);
+						const parsed: unknown = JSON.parse(urlState.metadata_filters);
+						if (
+							typeof parsed !== "object" ||
+							parsed === null ||
+							Array.isArray(parsed) ||
+							!Object.values(parsed).every((value) => typeof value === "string")
+						) {
