Key features
- Multi-model routing: route APAC requests across OpenAI, Anthropic, Azure, local models
- Automatic fallbacks: APAC provider outage/rate-limit retry without code changes
- Semantic caching: reduce APAC LLM costs 30-70% for repetitive queries
- Prompt management: version, deploy, and A/B test APAC prompts without deploys
- Cost observability: per-model, per-endpoint APAC token cost tracking
- One-line integration: change APAC API endpoint URL; no SDK changes required
Best for
- APAC production AI engineering teams running LLM applications at scale who need multi-provider reliability, cost tracking, and prompt management — particularly for high-volume APAC LLM applications where provider outages or cost overruns are unacceptable.
Limitations to know
- ! Adds network hop — APAC latency-sensitive applications may notice gateway overhead
- ! Vendor dependency — APAC teams should maintain direct LLM provider fallback if Portkey is unavailable
- ! Semantic cache effectiveness varies by APAC use case — low for creative or unique queries
About Portkey
Portkey is an AI gateway platform that sits in front of LLM API calls in APAC production applications — providing multi-model routing, automatic fallbacks, request caching, cost tracking, and prompt versioning without changing application code beyond the API endpoint. APAC teams use Portkey to make their LLM applications more reliable, observable, and cost-efficient.
Portkey's automatic fallback configuration routes APAC LLM requests to alternative providers when the primary provider has an outage or rate limit — if OpenAI returns 429 (rate limit) or 503 (outage) for an APAC request, Portkey automatically retries with Azure OpenAI or Anthropic without APAC application code changes. This fallback routing is critical for APAC production applications serving users who cannot tolerate LLM provider outages.
Portkey's semantic caching caches LLM responses by semantic similarity — when an APAC user asks "What is the capital of Singapore?" after another user asked "What's Singapore's capital?", Portkey returns the cached response rather than making a new LLM API call. For APAC applications with repetitive queries (FAQ bots, document classification, APAC template generation), semantic caching reduces costs 30-70%.
Portkey's prompt management system versions APAC prompts, tracks which prompt version is in production, and provides A/B testing for prompt variants — enabling APAC teams to iterate on prompt quality without code deployments. The observability dashboard tracks APAC token costs per model, per endpoint, and per user segment, giving APAC engineering leads visibility into AI cost attribution.
