## Post Option 1: The Story Hook

We upgraded our NIM container in production.

10 minutes later, everything crashed.

The culprit? A single environment variable default changed between versions.

No changelog mentioned it.
No warning was given.
$47,000 in downtime.

That's when I built nim-audit.

It's an open-source CLI that catches what humans miss:

→ Breaking changes between NIM versions
→ GPU compatibility issues BEFORE deployment
→ Environment variable risks and impacts
→ Policy violations that slip through code review
→ Behavioral drift between model versions

One command before every upgrade:

```
nim-audit diff old-image new-image
```

And you'll never be surprised again.

The tool now catches:
• API schema changes
• Memory requirement increases
• Driver version conflicts
• Configuration deprecations
• Quantization differences

We've prevented 3 production incidents since building this.

Sometimes the best code is the code that stops you from deploying bad code.

## Post Option 2: The Listicle

Stop deploying NIM containers blind.

I review 50+ NIM deployments per month.

Here are the 5 mistakes I see teams make:

1. Upgrading without checking breaking changes
2. Ignoring GPU memory requirements
3. Copy-pasting env configs between versions
4. No policy validation before prod
5. Assuming "same model = same behavior"

Every single one is preventable.

So I built nim-audit - a CLI that does the checking for you.

Before upgrade:
```
nim-audit diff v1.0 v1.1 --breaking-only
```

Before deployment:
```
nim-audit compat --image nim:latest --gpu A10
```

Before merging:
```
nim-audit env lint --env-file prod.env
```

It takes 30 seconds.
It saves hours of debugging.
It's free and open source.

Your future self will thank you.

## Post Option 3: The Controversial Take

Hot take: Most ML teams don't actually know what's in their inference containers.

They pull the latest tag.
They copy yesterday's config.
They pray it works.

I've seen it happen at startups.
I've seen it happen at Fortune 500s.
I've seen it cause $100K outages.

The problem isn't laziness. It's tooling.

Docker diff is useless for ML containers.
Changelogs are incomplete.
Testing takes too long.

So I built something different.

nim-audit gives you:

✓ Semantic diff (not just file changes)
✓ GPU compatibility matrix
✓ Environment impact analysis
✓ Policy-as-code validation
✓ Behavioral fingerprinting

One tool. Full visibility.

Example output:
```
⚠️  Breaking Changes Detected
━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• API: /v1/completions response schema changed
• Config: NIM_MAX_BATCH_SIZE default: 4 → 8
• Requirement: Min GPU memory increased to 24GB
```

Would you deploy without knowing this?

## Post Option 4: The Personal Journey

6 months ago I mass-deleted a production database.

Just kidding. But I did mass-crash a NIM cluster.

The upgrade looked safe:
- Same model ✓
- Same config ✓
- Newer version ✓

What I missed:
- Default batch size changed (OOM)
- New GPU requirement (incompatible)
- Deprecated env var (silent failure)

3 hours of downtime.
1 very angry Slack channel.
0 documentation that warned me.

So I spent weekends building nim-audit.

It's a pre-flight checklist for NIM containers:

```bash
# What changed?
nim-audit diff old new

# Will my GPU work?
nim-audit compat --gpu A10

# Is my config valid?
nim-audit env lint --env-file prod.env

# Does it meet policy?
nim-audit lint --policy enterprise.yaml
```

Now it's open source.

Because no one should mass-crash a cluster twice.

(Okay, I've done it twice. Hence the tool.)

## Post Option 5: The Technical Deep-Dive

Engineers love surprises.

Just not in production.

Here's how nim-audit prevents NIM deployment surprises:

𝟭. 𝗦𝗲𝗺𝗮𝗻𝘁𝗶𝗰 𝗗𝗶𝗳𝗳𝗶𝗻𝗴

Not file-level. Semantic-level.

Detects:
- Model weight changes
- Tokenizer modifications
- API schema breaking changes
- Environment variable impacts

𝟮. 𝗚𝗣𝗨 𝗖𝗼𝗺𝗽𝗮𝘁𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗠𝗮𝘁𝗿𝗶𝘅

Checks before you deploy:
- Compute capability
- Memory requirements
- Driver version
- Architecture support

𝟯. 𝗘𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁 𝗜𝗺𝗽𝗮𝗰𝘁 𝗔𝗻𝗮𝗹𝘆𝘀𝗶𝘀

Every env var mapped to:
- Performance impact (latency/throughput)
- Resource impact (memory)
- Stability impact (determinism)
- Known failure modes

𝟰. 𝗕𝗲𝗵𝗮𝘃𝗶𝗼𝗿𝗮𝗹 𝗙𝗶𝗻𝗴𝗲𝗿𝗽𝗿𝗶𝗻𝘁𝗶𝗻𝗴

Same model, different behavior?

Detect response drift between versions with standardized test suites.

𝟱. 𝗣𝗼𝗹𝗶𝗰𝘆-𝗮𝘀-𝗖𝗼𝗱𝗲

```yaml
rules:
  - id: no-root
    condition: user != 'root'
    severity: error
```

Enforce org standards automatically.
