Operator take · The most static board on this page, and it has now gone another three days without a single Elo point moving anywhere in the top five. GPT-5.6 Sol at xHigh still leads at 1257 with Claude Opus 4.6 Search four points back at 1253, which is a tie given intervals of 7 and 5, not a win. OpenAI holds first and third, Anthropic holds second, fourth, and fifth. The stillness is the signal: search-grounded quality is bounded by the index behind the model and by citation discipline, not by raw model IQ, so it does not lurch the way the reasoning boards do. First to fifth spans 27 points. That is not enough to justify moving your research workflow between stacks. Keep using whatever your tool already runs, Claude in Claude Code and Cowork, GPT in ChatGPT, and spend the effort on your source list instead.

How to Read These Rankings

Four rules before you switch models

  • Every ranking is task-specific. The #1 agent model is not the #1 writer, and neither is the right pick for 10,000 Clay rows.
  • Scores come from public leaderboards (Arena, Artificial Analysis) with capture dates shown. Preference Elo measures which output people like, not whether work gets completed.
  • Reasoning effort and harness matter: the same model at a different effort tier or in a different agent harness ranks differently.
  • Cheap plus fast beats frontier for volume work. Route by job, not by brand loyalty.

Frequently Asked Questions

Prospect & Market Research: common questions

Which AI model is best for Prospect & Market Research?

As of September 23, 2026, GPT-5.6 Sol (xHigh) from OpenAI ranks first for Prospect & Market Research at 1257 Arena Elo (±7) on the Arena Search leaderboard.

Where do these AI model rankings come from?

Prospect & Market Research is scored from the Arena Search leaderboard (https://arena.ai/leaderboard), measured by Arena Elo. DemandLab captures the public results, maps them to the go-to-market job they apply to, and publishes them unmodified. No scores are estimated, blended, or adjusted, and any board that cannot be read on a given day is left unchanged rather than guessed.

How often is the GTM Model Leaderboard updated?

Daily. The last capture was September 23, 2026. Model leaderboards move faster than most buying cycles, and positions inside a confidence interval can flip overnight, so DemandLab treats a single day's order as one observation rather than a trend.

Should I switch to the top-ranked model?

Not automatically. The most static board on this page, and it has now gone another three days without a single Elo point moving anywhere in the top five. GPT-5.6 Sol at xHigh still leads at 1257 with Claude Opus 4.6 Search four points back at 1253, which is a tie given intervals of 7 and 5, not a win. OpenAI holds first and third, Anthropic holds second, fourth, and fifth. The stillness is the signal: search-grounded quality is bounded by the index behind the model and by citation discipline, not by raw model IQ, so it does not lurch the way the reasoning boards do. First to fifth spans 27 points. That is not enough to justify moving your research workflow between stacks.
