Tighten executor, usage, model-resolution, and state-management
code with explicit types and safer record handling to reduce runtime
edge cases across providers.
Also normalize management-token failures to 403 responses, require API
keys consistently on cloud agent task routes with CORS-safe errors,
refresh stale Gemini CLI project IDs, prioritize Gemini search tools
correctly, add new provider/model registry entries, and serialize
integration tests for more reliable CI.
Models like antigravity/claude-sonnet-4-6 route through Google's internal
Cloud Code API which returns HTTP 400 when thinking/reasoning parameters
are included in the request body.
Changes:
- open-sse/services/modelCapabilities.ts: add supportsReasoning() function
with a denylist of known-unsupported patterns (antigravity/claude-sonnet-*)
and a registry-based lookup hook (supportsReasoning flag per model)
- open-sse/services/thinkingBudget.ts: in applyThinkingBudget(), add early
exit before the mode switch — if model string is present and
supportsReasoning() returns false, call stripThinkingConfig() immediately
regardless of the configured ThinkingMode
This is fully backward-compatible: models not in the denylist are unaffected,
and the supportsReasoning registry flag defaults to null (pass-through).
Fixes: HTTP 400 errors on antigravity provider when client sends requests
with thinking/reasoning budget parameters (e.g. claude-sonnet-4-6 via AG).

T01 (P1): requested_model column in call_logs
- Migration 009_requested_model.sql: ALTER TABLE call_logs ADD COLUMN requested_model
- callLogs.ts: INSERT + SELECT updated to include requestedModel field
T02 (P1): Strip empty text blocks from nested tool_result.content
- New stripEmptyTextBlocks() recursive helper in openai-to-claude.ts
- Applied on tool_result content before forwarding to Anthropic
- Prevents 400 'text content blocks must be non-empty' errors
T03 (P1): Parse x-codex-5h-*/x-codex-7d-* headers for precise quota reset
- parseCodexQuotaHeaders() in codex.ts extracts usage/limit/resetAt
- getCodexResetTime() returns furthest-out reset timestamp for safe unblocking
T04 (P1): X-Session-Id header for external sticky routing
- extractExternalSessionId() in sessionManager.ts reads x-session-id,
x-omniroute-session, session-id headers with 'ext:' prefix to avoid collisions
T06 (P2): account_deactivated permanent expired status on 401
- ACCOUNT_DEACTIVATED_SIGNALS constant + isAccountDeactivated() in accountFallback.ts
- Returns 1-year cooldown (effectively permanent) to prevent retrying dead accounts
T07 (P2): X-Forwarded-For IP validation
- New src/lib/ipUtils.ts with extractClientIp() and getClientIpFromRequest()
- Skips 'unknown'/non-IP entries in X-Forwarded-For chain
T10 (P2): credits_exhausted distinct account status
- CREDITS_EXHAUSTED_SIGNALS + isCreditsExhausted() in accountFallback.ts
- Returns 1h cooldown with creditsExhausted flag, distinct from rate_limit 429
T11 (P1): max reasoning_effort -> budget_tokens: 131072
- EFFORT_BUDGETS and THINKING_LEVEL_MAP updated with max: 131072, xhigh: 131072
- Reverse mapping now returns 'max' for full-budget responses
- Unit test updated to expect 'max' (was 'high')
T12 (P3): Model pricing updates
- MiniMax M2.7 / MiniMax-M2.7 / minimax-m2.7-highspeed pricing added
T15 (P1): Array content normalization for system/tool messages
- normalizeContentToString() helper exported from openai-to-claude.ts
- System messages with array content now correctly collapsed to string
OmniRoute is an intelligent API gateway that unifies 20+ AI providers behind a single
OpenAI-compatible endpoint. Features include intelligent routing with 6 strategies,
multi-format translation (OpenAI/Claude/Gemini/Responses API), circuit breakers,
semantic caching, combo fallback chains, real-time health monitoring, and a full
dashboard with provider management, analytics, and CLI tool integration.
Key highlights:
- 20+ providers (Claude Code, Codex, Gemini CLI, GitHub Copilot, iFlow, Qwen, Kiro, etc.)
- 6 routing strategies (Fill First, Round Robin, P2C, Random, Least Used, Cost Optimized)
- Export/Import database backup with full archive support
- Translator Playground with 4 modes (Playground, Chat Tester, Test Bench, Live Monitor)
- 100% TypeScript across src/ and open-sse/
- Docker support with multi-stage builds
- Comprehensive documentation and 9 dashboard screenshots
