The AI lab business: industry and inference research

Evidence cut: 2026-11-06. The dates attached to individual claims identify the underlying announcement, filing, or tariff. Announced future capacity is a promise or expectation. An activated site is a different observation. Company claims, independent measurements and the game's assumptions belong on separate cards.

The player runs one part of a value chain: accelerator makers and utilities enable physical compute; site operators and clouds sell capacity; labs turn staff, data and compute into checkpoints; serving companies deliver requests; channels bring customers. One company can sell several of those layers. The provider roster distinguishes them. The first mission uses a single thread through that chain: a cheaper enterprise quote forces a lab to change its costs before it scales.

The lab as a business

Observed as of 2026-11-06. Anthropic's Nov 2 S-1/A reported $33.242B of recognized revenue, $4.812B of functional cost of revenue, $19.240B of R&D and $6.569B of operating cash inflow for the nine months ended Sep 30, 2026. Its $18.808B of compute and infrastructure spans functions and overlaps those expense categories. It disclosed $5.0B in short-term compute for Q3, priced materially above comparable multi-year commitments. It sells metered usage and subscriptions, and some enterprise customers commit to minimum spend at a negotiated price list. This is company-level accounting. Model-level realized prices, margins, training-run costs and the terms of individual discounts remain calibration assumptions absent specific disclosures.

Game rule. Keep cash, recognized revenue, serving cost, R&D expense and future commitments in separate ledgers. Equity funding increases cash at closing and dilutes ownership. Debt adds repayments and collateral constraints. Customer prepayments move cash early, with sales recognized as usage is delivered or subscriptions elapsed. Show runway next to the payment calendar. Renewals depend on service reliability, task results and commercial terms. Paid token price, fully loaded serving cost, R&D, and contribution per successful job get separate lines. A lab can sell a profitable API while losing cash building its next model. Product options include direct API, subscriptions with usage caps, enterprise minimum-spend contracts, and cloud marketplace distribution. Keep paid API and one anchor enterprise customer in the first scenario.

Talent, data and release. Research, distributed systems, data and safeguards are distinct staffing bottlenecks. Claude Opus 4.6's historical system card describes public web information, non-public third-party data, contractor and labelling data, opt-in user data and internally generated data, with filtering, deduplication and post-training. Give datasets provenance, domain coverage, usage rights, preparation time and separate held-out evaluation sets. Research and systems teams compete for the same experiment window. Have capability trials and cost/latency checks determine product readiness, with a separate misuse and security release gate. Options include further mitigation, a monitored partner preview, and a broader rollout. Anthropic's voluntary Responsible Scaling Policy, its April 2026 limited Mythos Preview for defensive partners, and the EU's GPAI obligations for documentation and additional systemic-risk measures are separate evidence for those mechanics.

Who sells which layer

Counterparty Observed example Playable contract
Hyperscaler and strategic investor In 2025 AWS reported activating Project Rainier for Claude with nearly 500,000 Trainium2 chips. In April 2026 Anthropic announced an AWS technology spend commitment above $100B over ten years for up to 5 GW of new capacity, with about 1 GW expected by year-end 2026. AWS remained its primary training and mission-critical cloud. The announcement also described Bedrock, Vertex AI and Microsoft Foundry distribution. Amazon's announced $5B investment was included within the $65B Series H announced in May, with up to $20B additional investment described in April. AWS on activating Project Rainier · April compute agreement · Series H Bundle silicon, staged training capacity, investment and distribution as separately priced clauses. A port to partner-specific hardware spends systems team time. Distribution brings customers with a fee and different procurement friction. Equity only enters cash on its funding milestone.
Neocloud CoreWeave's 2025 10-K disclosed on-demand service alongside multi-year take-or-pay contracts averaging about five years at year-end. Committed contracts commonly included prepayments. In Q2 2026 it reported 1.5 GW active and about 3.7 GW contracted. CoreWeave 10-K · Q2 2026 results A prepayment buys a delivery date and reserved accelerator topology. An oversized deal charges for idle capacity. On-demand covers peaks at a higher scenario price when suitable capacity is available.
Colocation or dedicated facility Applied Digital disclosed 400 MW of contracted critical IT load at Polaris Forge 1 across 15-year leases to CoreWeave, with delivery phased. Anthropic's S-1/A describes its own hybrid sourcing, including leasing chips separately and hosting them in dedicated facilities operated on its behalf.

A delay can strand hardware and force temporary cloud spending.

Rival behavior. OpenAI sought additional specialized compute from CoreWeave, which in September 2025 disclosed cumulative contracts worth up to about $22.4B. Its April 2026 Microsoft amendment kept Microsoft as primary cloud and retained Azure-first product shipping subject to the stated exception, while permitting sales via other cloud providers and making Microsoft's IP license nonexclusive. Model rivals as repeat buyers that can reserve the same scarce clusters, plus distinct cloud storefronts with their own commercial terms. Expose rivalry through bids, delivery queues, model launches and customer procurement. CoreWeave's September 2025 agreement · OpenAI and Microsoft amendment

Model research, serving and the price of a completed task

What the lab actually researches

Choice Evidence and implication for play
Start from open weights or train a base model A licensed checkpoint lets a new lab specialize and launch sooner. Training a new base model buys control over the data and checkpoint but ties up researchers and a contiguous cluster reservation. Ai2 publishes Olmo 3’s pretraining, mid-training, long-context extension, supervised fine-tuning, preference optimization and reinforcement learning with verifiable rewards. Model each as a decision with a data prerequisite and a job in the queue. Put rights, curation, deduplication and a protected evaluation set on the data card. Ai2 Olmo 3 model flow
Dense vs mixture of experts (MoE) Dense layers use their full weights while MoE layers route tokens to a subset of experts. DeepSeek-V3 reported 671B total parameters and 37B activated per token. Its report discusses load balance and cross-node communication. Give MoE separate active compute, total weight memory and interconnect requirements. Show the target hardware’s throughput and memory fit on the model card. The play advantage depends on the cluster and traffic. DeepSeek-V3 technical report
Small/distilled vs general purpose A smaller checkpoint can be trained directly or distilled using outputs from a teacher. DeepSeek published R1-distilled Qwen and Llama checkpoints and identifies their base models. Give the small model strong economics in workloads it passes and a quality ceiling elsewhere. Record access and distillation terms on the card. Chinchilla studied the tradeoff between parameter count and training tokens under a training compute budget. A later study explicitly adds inference demand and finds conditions where a smaller model trained longer reduces total cost. DeepSeek-R1, Chinchilla, Beyond Chinchilla-Optimal
Reasoning and tool use Qwen3’s original release includes dense and MoE checkpoints with selectable thinking and non-thinking modes. R1 demonstrates reasoning-oriented post-training. OpenAI documents invisible reasoning tokens billed as output on supported models. Make reasoning capability a training choice and reasoning effort a serving policy. Let hard jobs benefit from extra effort where measured, while latency, token use and possible truncation change. Qwen3, DeepSeek-R1 paper, OpenAI reasoning guide
Specialist workload or new generation method Classification, embedding/retrieval and reranking are useful specialist roles if “decision” means choosing an action. If the intended term was “diffusion,” LLaDA is a documented example of masked diffusion for language generation. Keep both as future branches. The first scenario needs one small dense model, one more capable reference model and an effort setting. FlagEmbedding, Large Language Diffusion Models

Keep separate estimates for an individual run, the full R&D program and ongoing serving. DeepSeek-V3 reported 2.788 million H800 GPU-hours across its official training stages. Its $5.576 million figure applies an assumed $2 per H800 GPU-hour, and its accounting excludes earlier research and ablations. That supports an evidence card for a run scope. Staff, data, unsuccessful experiments and deployment have separate budget lines. DeepSeek-V3 report, Table 1, Cottier et al. cost methodology

What drives serving cost and demand

Use a protected, versioned task suite for simulated contract acceptance, e.g. extraction validity and exact-field accuracy for batch, and issue resolution plus response deadlines for support. Keep capability, safety and performance results visible as separate dimensions. Label simulated scores and compare reruns under the same workload mix. Stanford HELM, MLPerf Inference Datacenter

What to calibrate

Evidence we can pin What it anchors What remains a game assumption
Dated direct rate card Input, output, cache, region, batch and tier categories for a customer bill Wholesale economics, margins, actual discounts and demand elasticity
Workload test with model revision, hardware, precision and traffic Serving quality, successful throughput and percentile latency within that test Values outside the measured profile; no conversion from an API list rate
Company filing or dated deal announcement Size and structure of commitments, categories of cash and spending, time to delivery How much a given startup pays per GPU hour, when its site opens, and its financing odds
Utility tariff, interconnect document or power announcement Billed MW, delivered MWh, curtailment conditions, delivery and credit structure Synthetic region, permits, water budget and outage events for the game

For v0, keep three distinct quantities on every turn: customer tariff, expense of serving the cohort, and cash due even if idle. Calculate cost per successful job after paying for all attempts and commitments that served the cohort; compare only jobs of the same kind with the same deadline. Put pretraining and post-training experiments in R&D. Show site capex in the cash forecast and allocation/depreciation in an optional accounting view; combining both in one period expense would count the same asset twice. Treat vendor credits as temporary and carry the expiry. For the first mission, make the assumptions explicit and fixed. A future calibration pass can substitute one measured workload and compare player choices without rewriting the rest of the economy.
