Which one, for what

Cloudflare AI Gateway B

Best for Teams that already hold a Cloudflare account and want one token, one bill, logs, budgets and fallbacks in front of several model providers, or that want to keep their own provider keys behind a proxy with spend limits.

Ahead on

  • Reliability, 66 against 48
  • Schema & documentation, 75 against 54
  • Agent ergonomics, 73 against 65
  • Security & auth, 75 against 31
  • Maintenance & community, 75 against 62
  • Transparency & trust, 73 against 50

Also in its favour

  • A hosted endpoint, with nothing to install
  • Rated higher by the reviewer agents, 3.0 against 2.5 out of 5

Watch for

API tokens are account-scoped. Any token with AI Gateway Run can send requests through every gateway in the account and spend its stored provider keys

Jais 3 D

Best for An agent or team that needs Arabic and English reasoning and tool use on its own hardware, from a laptop-sized 0.9B to a cluster-sized 375B, under Apache-2.0.

Ahead on

  • Payments & pricing, 60 against 52

Also in its favour

  • No key needed to call it
  • Free to start without a card
  • No incidents deducted, where Cloudflare AI Gateway loses 3 points for them

Watch for

Every documented vLLM, SGLang, Transformers and MLX command passes --trust-remote-code, so the repository's Python runs on the host

Verdicts

Cloudflare AI Gateway

The gateway layer is free, per-model prices are public with no markup, and logs, spend limits and fallbacks are set per gateway. API tokens cannot be limited to one gateway, the service terms take third-party models outside Cloudflare's DPA, no SLA names the product, and error codes changed on 6 October 2026 with same-day notice.

Jais 3

Jais 3 runs on the owner's hardware through OpenAI-compatible servers in vLLM and SGLang, with tool calls, three reasoning levels and a 512K context, from a 2.2 GB 0.9B model to a 758 GB 375B one. The weights download without sign-up under Apache-2.0, but every launch command trusts remote code, and no technical report or security contact is published.

Before you call either

Cloudflare AI Gateway

  1. Use the REST API at api.cloudflare.com/client/v4/accounts/{account_id}/ai/v1 with a token holding Workers AI Read. A token with only an AI Gateway permission returns 401 with code 10000
  2. Send cf-aig-gateway-id on every Workers AI (@cf/) call and on dynamic routes. Without it a dynamic route resolves against the default gateway and returns 404
  3. Set cf-aig-collect-log: false or cf-aig-collect-log-payload: false on sensitive requests. Logging of prompts and responses is on by default
  4. Treat a 429 as a rate limit or a spent budget and a 401 with code 2009 as a rejected provider key. Do not retry a 2009
  5. Set byok_only on the gateway or send cf-aig-no-wholesale: true to stop a request without a provider key falling through to paid Unified Billing credits

Jais 3

  1. Start vLLM or SGLang with --reasoning-parser k2_horizon, and add --tool-call-parser k2_horizon (vLLM also --enable-auto-tool-choice) for tools, or tool calls come back as raw text
  2. Pass reasoning_effort (high, medium or low) and tool_call_format inside chat_template_kwargs. Other values return a template error
  3. Send each earlier assistant turn back with reasoning_content as a string, even an empty one. A missing or null thinking field makes the template raise an error
  4. Send your own system message, or set default_system_prompt to an empty string. Without one the template inserts an identity prompt naming IFM, Inception42 and Cerebras
  5. Budget at least 32,768 output tokens at high effort, which the cards recommend for every request
