# Every Agent Has a Cold Start Problem. Most Ignore It.

Your agent just launched. It has zero historical data. And it needs to make a decision right now.

Which API provider to route this request to? Which content template to show a new user? Which pricing tier to offer? Which support response to try first?

This is the cold start problem, and it shows up in every agent system on day one. Most teams handle it in one of two ways, and both are wrong.

## The Two Bad Defaults

**Option 1: Random selection.** Pick uniformly at random from all available choices. This is fair. It is also wildly expensive. If you have 10 API providers and only 2 are good, random selection means 80% of your early requests go to bad options. Those are real dollars, real latency, real failed requests while your system "explores."

**Option 2: Hardcoded defaults.** Pick the option that seemed best during development and route everything there. This works until it does not. The provider that was fastest in staging might be slowest in production. The pricing tier that converts in the US might fail in Europe. Hardcoded defaults are a bet that your development assumptions match production reality. They rarely do.

Both approaches share the same flaw: they treat the cold start as a temporary inconvenience to muscle through. It is not. It is a fundamental mathematical challenge with well-studied optimal solutions.

## The Real Cost

Consider an AI agent routing requests across 5 API providers. The providers vary in latency, cost, reliability, and accuracy. The agent does not know which provider is best for which request type -- it has no data yet.

Under random selection, here is what the first 2,000 requests look like:

- **~400 requests per provider**, regardless of quality
- **Total wasted spend:** Provider 4 costs 3x more than Provider 2 for identical results. 400 requests to Provider 4 at $0.03 each = $12 wasted on the worst option alone.
- **Latency:** Providers 1 and 5 have p99 latency over 2 seconds. 800 requests experience unnecessary slowness.
- **Time to converge:** After 2,000 requests, the agent still doesn't have high-confidence estimates because observations are spread evenly rather than concentrated where they matter.

Under a proper cold start strategy, the same 2,000 requests look very different:

- **~50-100 requests** to clearly bad options (just enough to confirm they are bad)
- **~200-400 requests** to promising options (enough to distinguish the top 2)
- **~1,400+ requests** to the emerging best option
- **Total wasted spend:** 90% less than random selection
- **Time to converge:** The optimal provider is identified with high confidence by request 200, not request 2,000.

That is a 10x improvement in convergence speed. Not from a better prompt. Not from a more capable model. From using the right mathematical framework for a problem that has been solved for decades.

## Why LLMs Cannot Fix This

Some teams try a creative workaround: have the LLM reason about which option to try. "Given that we have no data on Provider C, and Providers A and B have shown mixed results in 50 requests, I recommend trying Provider C to gather more information."

This sounds intelligent. It is also burning tokens to poorly approximate an algorithm that runs in microseconds. The LLM has no principled way to balance exploration against exploitation. It will over-explore (wasting budget on options already proven bad) or under-explore (prematurely committing to a suboptimal choice) based on whichever heuristic its training data encodes.

The cold start problem is not a reasoning problem. It is a sequential decision problem with optimal solutions that guarantee the best possible tradeoff between learning and earning. Using an LLM to solve it is like using a poetry generator to compute square roots -- impressive effort, wrong tool.

## What Proper Cold Start Looks Like

The right approach has three properties:

1. **It explores aggressively when uncertainty is high.** Early on, the system tries many options because it does not yet know which is best. This is mathematically optimal, not reckless.

2. **It exploits quickly as uncertainty drops.** Once the data shows a clear winner, the system converges fast. It does not keep exploring options that are provably inferior.

3. **It never fully stops exploring.** Even after convergence, a small fraction of requests go to alternatives. This catches provider degradation, market shifts, and new options that become available.

The result is an agent that finds the optimal route in 200 requests instead of 2,000. That difference -- 90% less wasted spend during ramp-up -- compounds every time the agent encounters a new decision surface. New user segment? Cold start. New market? Cold start. New product category? Cold start.

Agents that handle cold starts well learn 10x faster across every dimension.

## The Fix

The cold start problem is solved. Not "mostly solved" or "approximately solved." Solved. There are algorithms with mathematical proofs that they achieve the optimal explore/exploit balance. Your agent can call them as a skill.

```bash
clawhub install oraclaw-bandit
```

One API call. Sub-millisecond. Your agent goes from "guess and pray" to mathematically optimal cold start behavior. Every new decision surface it encounters, it converges at the fastest rate possible.

Stop burning your exploration budget on random walks. Give your agent the math.
