How many people can use frontier AI systems inside the labs? We count 3,913 named model contributors. Dated staff records sum to about 13,100 people. Access for 5,000 people would require 38.2% of that workforce. Access lists remain private.

Andrej Karpathy estimated about 5,000 people. Scope: People with internal access to frontier-grade AI systems, the last step of a funnel that starts with about 6 billion people who have barely used LLMs. Supporting text: “And finally we get to the ~5,000 people (~0.00006%) with access to frontier-grade systems internally.” Our core scope covers Google DeepMind, OpenAI and Anthropic.

Key findings

  • We count 3,913 distinct contributor names across reports from 3 labs.
  • The latest dated all-staff observations sum to about 13,100 people.
  • An access count of 5,000 would cover 38.2% of that recorded workforce.
  • The wider set of 9 labs supplies 4,207 contributor names. Its full workforce is unknown.
Core reports name 3,913 contributors and record about 13,100 staffDistinct named contributors, claim reference and total staff in the core comparison. Unit: people. Staff dates differ.

Distinct names across core model reports: 3,913. Claim reference: 5,000. Dated staff total: 13,100. These measures describe credited work and a workforce ceiling proxy; internal access counts are unknown.

Contributor lists and dated staff sources for Google DeepMind, OpenAI and Anthropic appear in the tables below. Claim: Andrej Karpathy, 11 October 2026.

Start with the people credited on models

A model report gives the first check: people publicly credited with work on a model. The core definition covers developers of Gemini, GPT and Claude. We treat their general-purpose model families as frontier-grade for this comparison. The wider definition below shows the effect of including other model developers.

Core labLatest qualifying report in the source setNamed contributors
Google DeepMindGemini 2.5: Pushing the Frontier with Advanced Reasoning, Multimodality, Long Context, and Next Generation Agentic Capabilities (7 July 2025)3,434
OpenAIGPT-5 System Card (19 December 2025)486
AnthropicClaude Opus 4 and Sonnet 4 System Card (2025-05)No individual byline

Google DeepMind supplies 3,434 of the 3,920 available per-lab report credits (87.6%), the largest count. This share is calculated before matching names across labs; missing bylines can change the balance.

The per-lab counts sum to 3,920. Matching identical normalized names across labs removes 7 repeat entries, giving 3,913. This is a floor on the credited model work represented by these reports. Bylines can include outside contributors and former staff. Name variants and shared names can affect the count.

We use each lab’s latest qualifying report. Older reports remain in the archive. Anthropic, Meta Superintelligence Labs / Meta AI, xAI and Alibaba Qwen team have no individual byline on the latest qualifying report or model card. A missing byline leaves the contributor floor incomplete.

Staff totals set a ceiling proxy

We next ask how many employees could have access if it extended across the whole recorded workforce. The latest staff sources for the core comparison give a ceiling proxy of 13,100 people. The claim would require 38.2% of that recorded workforce to have access.

Core labSelected all-staff figure, date, scope and evidence
Google DeepMind5,600 (8 September 2025). Google DeepMind unit; broad unit headcount including Gemini teams. Selected as the latest dated all-staff observation. Source text: “The Google unit now has 5,600 employees.”
OpenAIabout 4,500 (21 March 2026). All company employees. Forecasts on the source page are excluded. Selected as the latest dated all-staff observation. Source text: “up from about 4,500 employees.”
Anthropicaround 3,000 (18 May 2026). All company employees. Selected as the latest dated all-staff observation. Source text: “Anthropic has around 3000 employees, up from roughly 300 in December 2023.”

We select each lab’s most recent dated observation of all staff in the source set. This rule excludes hiring targets, research-only totals, team subsets and planned cuts. The table shows the selected figure and its scope for each lab. Older observations remain in the source records below.

The archive also gives an all-staff observation for every core lab in 2024 and 2025. Taking each lab's latest observation within each year, with open-ended counts excluded, gives about 5,215 staff for 2024 and 10,900 for 2025. That is 109% growth. Observation dates within each year differ, so these sums give an approximate view of workforce change.

This ceiling includes every role. Access could include researchers, engineers, safety teams and other staff who test internal models. That is a possible reason for an access count to exceed a research-only count. The sources do not show who has permission. Staff figures come from different dates. Later hiring could make our total too low. Outside users with access would expand the relevant population. These records provide no current access bound.

Research shares show the size of technical teams

These dated records separate research teams from the wider workforce.

Mistral AI8 September 2026researchers3001,20025%source

The 38.2% access share needed in the core comparison falls within the observed research shares. That comparison describes workforce composition. Access policies could produce a different share. These shares describe different jobs and dates. We apply neither share to another lab. Research status alone leaves access permissions unknown.

A wider lab definition adds evidence gaps

The next scope adds Meta Superintelligence Labs / Meta AI and xAI through their Llama and Grok models. The broad scope also admits Mistral AI, DeepSeek, Moonshot AI and Alibaba Qwen team. It covers open-weight and general reasoning model families. This is an inclusive definition of frontier-grade. Thinking Machines Lab and Safe Superintelligence are left out because the supplied sources do not establish a qualifying frontier model report.

The broader definition adds 294 recorded contributor namesDistinct normalized names in each lab set. Unit: people. Counts are partial where reports lack names or cached text. The vertical line marks 5,000.

Core closed-model labs: 3,913 distinct contributor names; report counts available for 3 labs out of 3; staff ceiling proxy 13,100. Add Llama and Grok: 3,913 distinct contributor names; report counts available for 5 labs out of 5; staff ceiling proxy Unavailable. Broader model labs: 4,207 distinct contributor names; report counts available for 8 labs out of 9; staff ceiling proxy Unavailable.

Alibaba Qwen teamQwen3.5-Omni Technical Report (17 April 2026)No individual bylineNo lab-specific total found

Magistral is the latest qualifying general reasoning report in that lab's source set. Small-model and coding reports remain in the source archive. The latest qualifying report count is unavailable for Moonshot AI. Kimi K3 (27 July 2026) has no cached individual byline available for this run. Earlier reports supply no replacement count in the floor.

The broader documented floor remains 793 below the claim. Missing bylines and reports leave room for more contributors. The staff side also has gaps. xAI has an open-ended total of more than 1,200 (12 March 2025). A lab-specific staff total is missing for Alibaba Qwen team. The broader dated staff subtotal is 18,160. It excludes open-ended totals and labs with no staff figure. It supplies no full ceiling.

DeepSeek's latest qualifying report names 197 contributors. Its staff source reports about 160 (14 March 2025). The contributor count exceeds the staff figure. Different dates, outside contributors or different organizational scopes are possible reasons. The records do not resolve the mismatch, so this pair cannot define a valid staff range.

What this means for the access estimate

We estimate about 13,100 staff across the core labs from their latest dated all-staff records. Access for 5,000 people would reach 38.2% of that workforce. The scale is compatible with the recorded total. Contributor lists and workforce totals leave current access unmeasured.

A direct count needs current access rules and user lists from each lab. Missing public records leave our comparison incomplete.
