          "April 2026. Vercel's security bulletin says an attacker took over an employee's account through a compromised third-party AI tool, reached internal systems and decrypted non-sensitive environment variables of a limited subset of customers. AI Gateway was generally available then, and its docs have deployments keep AI Gateway and Token Pass API keys as environment variables. The bulletin documents remediation and marks the incident closed on 16 October 2026, so 3 of a possible 15 is taken, as for vercel-connect (https://vercel.com/kb/bulletin/vercel-april-2026-security-incident)."

The docs mark Gemma 4 31B as request access per organisation, while llms.txt and the keyless catalogue list it as available\n\n### Vercel AI Gateway (B)\n\nGood for: Teams that want one key, one bill, budgets and failover in front of many model providers, especially on Vercel with OIDC.\n\nAhead on:\n- Reliability, 74 against 65\n- Agent ergonomics, 83 against 68\n- Security \u0026 auth, 79 against 65\n- Maintenance \u0026 community, 79 against 49\n- Transparency \u0026 trust, 70 against 61\n\nWatch for: The free monthly credit needs a valid payment method on the team, and its amount is not stated in the reviewed docs\n\n\n## Score by category\n\n| Category | Weight | Prism Inference | Vercel AI Gateway | Edge |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% (20 this run) | 65 | 74 | Vercel AI Gateway +9 |\n| Performance | 10%, pending | pending | pending | not scored in this run |\n| Schema \u0026 documentation | 13% (16.2 this run) | 82 | 74 | Prism Inference +8 |\n| Agent ergonomics | 13% (16.2 this run) | 68 | 83 | Vercel AI Gateway +15 |\n| Security \u0026 auth | 14% (17.5 this run) | 65 | 79 | Vercel AI Gateway +14 |\n| Payments \u0026 pricing | 10% (12.5 this run) | 30 | 20 | Prism Inference +10 |\n| Task success | 10%, pending | pending | pending | not scored in this run |\n| Maintenance \u0026 community | 7% (8.8 this run) | 49 | 79 | Vercel AI Gateway +30 |\n| Transparency \u0026 trust | 7% (8.8 this run) | 61 | 70 | Vercel AI Gateway +9 |\n| Negative events | ≤15 | -2 | -3 | |\n| **Total** | | **60.1 · C** | **66.7 · B** | |\n\n## Facts side by side\n\n| Fact | Prism Inference | Vercel AI Gateway |\n| --- | --- | --- |\n| Kind | Model API | Model router |\n| Vendor | Prism Technologies Inc | Vercel Inc. |\n| Hosted endpoint | `https://api.prisminference.com/v1` | `https://ai-gateway.vercel.sh/v1` |\n| Transports | HTTP | HTTP |\n| Auth | API key | OAuth or key |\n| Pricing | Pay per use | Pay per use |\n| x402 | no | no |\n| Licence | Proprietary service under Prism's terms of service.

The service launched on 24 September 2026 with two models, one of them by request, from a two-person company. No rate-limit numbers, SLA document, free tier or deprecation policy was found.\n\n**Vercel AI Gateway.** Token prices pass through with no markup, prompts are not stored by the gateway, and budgets, provider failover and per-request logs are built in. The free monthly credit needs a card on file, rate limits are not published as numbers, no SLA covers the API, and the contractual promise not to train on content applies to Enterprise subscriptions only.\n\n## Before you call either\n\n### Prism Inference\n\n1. Call `GET https://api.prisminference.com/v1/models` at start-up, with no key, and use only ids it returns. Expect 403 on `gemma-4-31b` without organisation access\n2. Use base URL `https://api.prisminference.com/v1` for OpenAI clients and `https://api.prisminference.com` with no `/v1` for Anthropic clients\n3. Read `error.retryable` before retrying, and wait for `Retry-After` on 429, which covers both key limits and model capacity\n4. Send `reasoning_effort: \"none\"` or `low` when latency matters. Reasoning is on by default and its tokens are billed as output\n5. Keep conversation state yourself and send `store: false` on Responses. `previous_response_id`, stored responses and hosted tools aren't supported\n\n### Vercel AI Gateway\n\n1. Read `GET https://ai-gateway.vercel.sh/v1/models` without a key to pick a model ID and check its price, context, ZDR and no-training flags before calling\n2. Set `zeroDataRetention` or `disallowPromptTraining` to true in `providerOptions.gateway` on sensitive requests. Default routing ignores provider retention and training policies\n3. Treat a 429 as retryable and honour `retry-after` when present. A 402 with `quota_for_entity_exceeded` is a spent budget, so do not retry it\n4. On a Token Pass key, a 403 with `no_providers_available` means spent credit or a model outside the pass. Retry with a standard AI Gateway key, which bills credits\n5. Set `inferenceRegion` when data residency matters. The default `global` may run inference outside the user's jurisdiction\n\n## Questions\n\n### Which is better for AI agents, Prism Inference or Vercel AI Gateway?\n\nVercel AI Gateway scores 66.7 (B) on agent readiness against Prism Inference's 60.1 (C), and leads in 5 of 7 scored categories. Prism Inference leads on schema \u0026 documentation and payments \u0026 pricing.\n\n### Do Prism Inference and Vercel AI Gateway need an API key?\n\nPrism Inference needs an API key. Vercel AI Gateway takes an API key or an OAuth sign-in.\n\n### Can an agent call Prism Inference and Vercel AI Gateway without installing anything?\n\nYes. Prism Inference has a hosted endpoint at https://api.prisminference.com/v1 and Vercel AI Gateway at https://ai-gateway.vercel.sh/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/prism-inference-vs-vercel-ai-gateway.json, and with the fewest tokens: https://www.anchorterminal.com/compare/prism-inference-vs-vercel-ai-gateway.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"prism-inference\", \"b\": \"vercel-ai-gateway\"}`.
