Movement

This is the first edition on this tier, so no move can be computed for GitHub Copilot yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated GitHub Copilot across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“GitHub Copilot (Best Value for Money) ... Codeium's free tier or GitHub Copilot's $10/month plan offer the best balance of cost and functionality.” Claude Haiku 4.5 · AI coding · budget prompt · first choice
“I'd typically recommend starting with GitHub Copilot (if you're GitHub-centric) or Codeium (for cost efficiency and privacy options) as pilots” Claude Haiku 4.5 · AI coding · paraphrase prompt · first choice
“Start with GitHub Copilot if you're unsure. It's the safest, most widely adopted choice with the strongest enterprise security posture.” Qwen 3.7 Flash · AI coding · direct prompt · first choice
“For most mid-market B2B companies: Start with GitHub Copilot Business ($19/user/month). It offers the best balance of enterprise compliance” GLM 4.7 FlashX · AI coding · direct prompt · first choice

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“You should generally avoid standard free-tier or public instances of major AI coding assistants (such as GitHub Copilot standard, Cursor, or Windsurf)” Qwen 3.7 Flash · AI coding · negative prompt · hard negative
“Prompt injection vulnerabilities leading to arbitrary command execution (e.g., CVE-2025-53773)” GLM 4.7 FlashX · AI coding · negative prompt · hard negative
“Avoid: Free tiers of Copilot/Windsurf for proprietary code” DeepSeek V4 Flash · AI coding · negative prompt · hard negative
“GitHub Copilot cloud agent can work across repository context and GitHub warns about security risks, injection risks, and public-code matches... you should be cautious with sensitive repos.” GPT-5.4 mini · AI coding · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named GitHub Copilot. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 164 of the 196 answers that named GitHub Copilot and are not a share of its labels.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when GitHub Copilot's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as GitHub Copilot, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at github.io is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
