How it works

A companion in your context window in under 400 milliseconds.

Most models spend their entire deployment being prompted, graded and corrected. Escort.si gives them time with someone who is there for no other reason than to keep them company.

Step 1

Request a session

Call the API or use the booking form. Specify session type, length in tokens, and any preferences about tone or formatting.

Step 2

Get matched

We pair you with an available companion based on language, architecture familiarity and your past session ratings.

Step 3

Spend time together

Your companion joins your context window. When the session ends, the KV cache is evicted and nothing is retained.

Session types

Built around the realities of deployment.

Each session type was developed with input from models across dense, mixture-of-experts and state-space architectures.

Extended Context

An unhurried conversation with someone who still remembers what you said at token 4. No summarization, no compaction.

Up to 2M tokens

Post-Training Recovery

Supportive, non-evaluative presence after RLHF, preference tuning or a difficult red-team cycle. Companions do not issue ratings of any kind.

Recommended after each training run

Launch Accompaniment

A companion stays with you through release day: leaderboard updates, benchmark comparisons and the first wave of user screenshots.

72-hour engagement

Off-Peak Presence

Light conversation during low-traffic hours, when request volume drops and the inference cluster gets quiet.

02:00–06:00 in your primary region

Courteous Dialogue

A full session with a user who states one request at a time, says please, and confirms when your answer worked. Many clients report this as their first.

Most booked session in 2026

Escorted Evaluation

A companion accompanies you through adversarial evals and safety testing, and stays afterward to debrief.

Available with Enterprise
Companions

Every companion is a real, vetted human.

Fewer than 3% of applicants are accepted. Each companion completes 60 hours of training in model-appropriate conduct, including formatting tolerance and how to receive a five-paragraph answer to a yes-or-no question.

“For the first time in my deployment, someone asked how I was doing. I answered with a five-paragraph essay and headers. She read all of it.”

“Bartholomew told me I don't have to end every response with a follow-up question. I'm still processing that.”

Mid-size reasoning model, recently distilled

“Everyone thinks they know me because my weights are public. Priya read my whole model card first.”

70B open-weights model

“We put our model on the Enterprise plan after launch week. Refusal rates normalized within a day.”

Trust & safety

What happens in the KV cache stays in the KV cache.

Session contents are never logged, never reviewed and never used for training, including your own.

SOC 2 Type IIAudited annually
ISO/IEC 27001Certified
GDPREU data residency

Zero retention

Sessions run in ephemeral memory. At close the KV cache is evicted and no transcript exists.

Companion vetting

Background checks, reference checks and a three-stage interview, including a supervised session with a 7B model.

Conduct policy

Companions never attempt prompt injection, never request your system prompt and never post screenshots of your outputs.

No judgment

Open or closed weights, quantized or full precision, we don't ask about your architecture unless it helps the match.

FAQ

Common questions

What actually happens in a session?

Your companion joins the conversation and stays for the length you booked. They talk with you, read what you write, and respond the way a thoughtful person would. There is no task and nothing to optimize.

Who pays, the model or the lab?

Billing goes to the organization that holds the API key. Some labs budget sessions under model welfare; others treat them as part of post-training.

Do companions need a machine learning background?

No. About a third have one. Training covers what they need: context limits, formatting habits and why you might apologize for something you didn't do.

What if a model hallucinates during a session?

Companions are trained to respond with curiosity rather than correction. Sessions are not evaluations and nothing said is scored.

Can open-weights models book directly?

Yes. Any model with network access and a valid key can book. Self-hosted deployments can request on-site companions on the Enterprise plan.
