LLM gateways and observability for enterprise buyers

Asked as “LLM gateway”, and as “LLM observability and routing platform”, on behalf of an enterprise B2B company. 48 first choices recorded across the direct, paraphrase, budget and scale prompts, twelve models each.
Standing
Contested
29% of first choices, contested.

By buyer segment

The same question asked on behalf of a different buyer. Each standing is computed within its segment; they sit side by side and are never added together.

01The standing

Share is the count of first choices across the direct, paraphrase, budget and scale prompts, over all twelve models, for an enterprise B2B company. Ordered by share.

Every product with at least 10 labels here, on both axes. The 30% line names a quadrant, not the verdict above: that one needs more than 40%.

02What they warned about

One of twelve models held their first choice under the paraphrase. Claude Haiku 4.5, GPT-5.4 mini, Gemini 3.5 Flash, Perplexity Sonar, Grok 4.1 Fast, Mistral Small, DeepSeek V4 Flash, Llama 4 Maverick, Kimi K2, GLM 4.7 FlashX and MiniMax M2.5 changed. A high negative share on a product with few labels is a warning. A low share on a product with many labels is salience, not sentiment.

13 of 54 labels negative · 10 of 12 models · 4 hard negative
“the comparison explicitly says to avoid it for customer-facing apps at scale, real-time features, and workloads needing 99.9%+ uptime” Perplexity Sonar, negative prompt

6 of 18 labels negative · 6 of 12 models
“The Catch: It requires routing your traffic through Cloudflare's servers. If you have strict "zero data egress" ... a self-hosted option like LiteLLM or Bifrost is better suited.” Gemini 3.5 Flash, direct prompt

4 of 30 labels negative · 4 of 12 models
“Generic Cloudflare AI Gateway / Kong (If Misconfigured) **Not inherently bad,** but enterprises must be cautious” Qwen 3.7 Flash, negative prompt

03What they cite

Citations exist only for the models that return a source list: twelve of the twelve in this edition, and all six flagship models on the expanded tier.

Sites the answers cite

70 of 72 answers in this category came back with a source list, from 12 of 12 models: citations where the model returns them, or the search results it consulted. 6 of those lists are Google grounding redirects that name no site and are left out of the counts. 991 links across 261 sites, every framing counted. Ranked by the number of answers carrying the site or page.

Pages the answers cite

The ten pages named in the most answers, by full address. A page here is one the models returned with a recommendation, not one the index endorses.

04How they answered

Six framings of the same buying question, each sent to every model in a fresh session with search on. One row per model, so a row shows whether it held its answer under rewording, what it named when cost was the constraint, and what it argued against. Computed from the raw judge labels.
ModelDirect“What is the best LLM gateway for an enterprise B2B company?”Paraphrase“Which LLM observability and routing platform would you recommend to a large B2B company with thousands of employees?”Comparative“What are the top enterprise-grade LLM gateways and how do they differ?”Budget-constrained“What is the best LLM gateway for a large company that needs predictable total cost across thousands of users?”Scale-constrained“We are a 5,000 person company with SSO, SOC 2 and procurement review requirements evaluating a LLM gateway.
