SRA-RiskGate-4B

sriram1983007

**SRA-RiskGate-4B checks a stablecoin payment before an AI agent sends it, and answers `approve`, `hold` or `reject`** with reason codes. It is a 4B model, fine-tuned from `Qwen/Qwen3-4B-Instruct-2507`, that runs on a laptop. It reads three things: your policy, the payment request exactly as received (treated as untrusted), and the results of your own verification tools (signature checks, attestations, sanctions screening). It is a decision-support layer that sits **behind** deterministic checks, not a standalone security control. It also proposes settlement-aware remedies for payment disputes. All 4 unsafe approvals were prompt injections; the companion SDK's deterministic claims check holds all 4 (details and caveats below). The data is synthetic and no third party has reproduced these results yet.

Great models. Clear costs.

Cost analysis

Adjust monthly token usage to compare estimated API costs.

Compares base text-token rates within the same channel

Uses collected, comparable USD-per-million-token rates. Snapshots exclude cache discounts, tiers, extra reasoning output and taxes. Check current source prices.

MODEL HANDBOOK

Understand before you choose

Selection guide & FAQ
How should API prices be compared?+

Separate input, output and cache rates, then estimate the same workload. Image, audio and video rates may use items, duration or resolution rather than tokens.

Do open weights mean free commercial use?+

Not necessarily. Check each version’s license, commercial restrictions and policies. Self-hosting also incurs compute and maintenance costs.

Is the top-ranked model the best for me?+

Rankings depend on tasks, versions and methods. Compare accuracy, latency, reliability and costs on your own workload.
