How an AI gateway improves the management of AI deployments

As AI adoption accelerates across industries, the complexity of managing AI deployments is growing just as fast.

Whether you're building with OpenAI, Anthropic, Cohere, or open-source models, getting AI into production and keeping it reliable is far from straightforward. Each provider has its own APIs, rate limits, performance quirks, and cost structures.

Add to that the challenge of securing inputs and outputs, monitoring prompt behavior, and managing costs, and you end up with a deployment mess that's hard to scale and even harder to govern.

The challenges of managing AI deployments

Deploying AI models isn’t as simple as sending a prompt and getting a response. Once your app is in production, you face a different set of challenges:

a. Fragmentation across providers

Every model provider has different APIs, request formats, token pricing, and SLAs. Switching between them or using multiple simultaneously creates integration overhead and increases the chance of errors.

b. Limited observability

You often lack full visibility into what prompts are being sent, how models are responding, and where failures occur. Debugging production issues or understanding how a prompt evolved becomes a manual and error-prone task.

c. Unpredictable costs

With token-based pricing models and variable response lengths, tracking and optimizing costs is difficult. One bad prompt can blow your budget, especially if sent at scale.

d. Security and compliance risks

LLMs can leak or output sensitive data if not properly monitored. Without guardrails, there’s no way to enforce redaction, detect harmful content, or meet compliance requirements.

e. Rapid iteration demands

Prompts and model configurations change fast. But pushing those changes in production often requires code deployments, slowing down iteration and increasing the risk of breaking things.

How an AI gateway helps improve deployment management

An AI gateway like Portkey fundamentally improves how teams build, monitor, and scale AI applications. Here’s how:

a. Centralized routing and control

An AI gateway lets you decouple your application from any single model provider. You can route traffic to multiple LLMs, OpenAI for some use cases, Claude for others, without changing your app code. You can also:

• Set up fallbacks: If one provider fails or hits a rate limit, route to another.
• Run A/B tests: Compare model outputs in production without duplicating logic.
• Control traffic: Direct different teams, use cases, or users to different models based on metadata.

This routing flexibility makes your AI stack resilient and future-proof, especially as the LLM landscape continues to evolve.

b. Full visibility into prompts and responses

In most LLM setups, you only get basic logs, if any. With an AI gateway, every prompt, response, token count, latency, and error is logged centrally.

• Trace issues: Debug broken prompts or investigate spikes in latency.
• Track changes: Monitor how prompts evolve and how outputs vary.
• Enable collaboration: Share prompt logs across teams to align on what’s working.

This level of observability is critical for teams shipping AI features into production and for avoiding silent failures that hurt user experience.

c. Cost and performance optimization

Running LLMs in production can get expensive fast. Without proper controls, it’s easy to rack up large bills from inefficient prompts, long outputs, or redundant requests. An AI gateway gives you the tools to keep usage and spending under control.

• Token-level analytics: See which prompts or endpoints are consuming the most tokens.
• Caching: Automatically reuse responses for repeated prompts instead of paying for the same output multiple times.
• Rate limiting and quota enforcement: Prevent overuse by setting per-team, per-endpoint, or per-user limits.
• Budget guardrails: Get alerts or block traffic when you’re close to budget thresholds.

Instead of retroactively fixing billing issues, you can proactively manage usage and optimize cost per call, without slowing down development.

Security and compliance enforcement

When working with sensitive data, especially in regulated industries like finance or healthcare, you can’t afford to treat AI calls as a black box. An AI gateway gives you the control layer needed to ensure that all inputs and outputs are secure and compliant.

• Input redaction: Automatically remove or mask sensitive fields (e.g., names, emails, credit card numbers) before they reach the model.
• Output filtering: Block responses that include PII, offensive content, or hallucinated facts.
• Audit logging: Maintain a complete, tamper-proof record of every AI interaction, tagged with metadata for auditing and investigations.
• Policy enforcement: Apply org-wide rules like “only use HIPAA-compliant providers” or “never send prompts over a certain length.”

Instead of building these controls into every application, the gateway enforces them consistently across your entire organization, reducing risk and simplifying compliance.

Prompt and version management

Prompts are a core part of your application logic, but managing them in production is often chaotic. Without a centralized system, teams hardcode prompts, track versions in docs or spreadsheets, and deploy changes manually, leading to bugs, regressions, and slow iteration.

An AI gateway streamlines this process by treating prompts as first-class citizens:

• Centralized prompt store: Manage all prompts in one place, accessible across teams and environments.
• Versioning: Track changes to prompts over time, compare diffs, and roll back if needed.
• Dynamic updates: Swap or update prompts instantly without redeploying code.
• Performance tracking: Measure how different prompt versions perform on real traffic (e.g., cost, latency, quality feedback).

This gives teams the ability to ship faster, experiment safely, and scale AI features without creating tech debt.

Get started

As AI adoption moves from experimentation to production, the need for better infrastructure becomes clear. Without the right control plane, teams struggle to manage costs, debug issues, enforce security, and iterate quickly.

An AI gateway solves this by sitting between your apps and model providers, giving you routing flexibility, deep observability, strong security controls, and centralized prompt management. It turns fragmented, fragile AI deployments into something scalable, reliable, and auditable.

If you’re serious about shipping AI to production at scale, an AI gateway is essential. To know more about how this helps your org, book a demo with us or get started for free.
