Token pricing is the foundation of AI platform cost analysis — and it has become one of the most rapidly changing cost variables in enterprise IT. The per-token price for GPT-4-class capabilities has declined by approximately 80% in 24 months. New open-source models have created self-hosted alternatives that cost pennies per million tokens versus dollars for API access. The competitive landscape has expanded from two primary providers (OpenAI, Anthropic) to a dozen serious contenders with different price-performance profiles.
This article provides a complete, platform-by-platform token price comparison for March 2026 — covering published list prices, enterprise benchmark discounts, and the effective cost factors that determine which platform actually delivers the lowest total token cost for a given workload. It is part of the AI & GenAI Platform Pricing: Enterprise Benchmark Guide, which provides the full strategic context for enterprise AI procurement.
How to Read AI Token Pricing
Before the comparison tables, a brief primer on token pricing mechanics that are frequently misunderstood in procurement contexts.
Input vs. Output Tokens
All major AI APIs charge separately for input tokens (the text sent to the model — prompts, context, documents) and output tokens (the text generated by the model — responses, summaries, analyses). Output tokens are consistently priced higher than input tokens — typically 2–5x higher — because generation is computationally more intensive than attention over an existing context.
For enterprise workloads, the input/output ratio is a critical cost variable. Document summarization workloads (long input, short output) have very different cost profiles than content generation workloads (short input, long output). Procurement teams should model expected input/output ratios for each use case before comparing platform costs — a platform that looks expensive on output tokens may be cheapest for a summarization-heavy workload.
Context Window and Caching
Extended context windows (100K+ tokens) allow models to process entire documents in a single call. Most providers charge separately for cached context — a significant discount for tokens that have been processed in a prior turn within the same session. Organizations with multi-turn conversational AI workloads can reduce costs significantly through prompt caching, though the mechanics vary by provider.
Batch vs. Real-Time Pricing
Several providers offer batch processing pricing for workloads that don't require real-time response. OpenAI's Batch API, Anthropic's Message Batches, and Google's batch prediction endpoints all provide 40–50% discounts versus synchronous API pricing for asynchronous workloads. For document processing, data extraction, and analytics use cases that don't require immediate responses, batch pricing is a significant cost reduction lever that many procurement teams don't benchmark separately.

Flagship Model Pricing Comparison
The table below compares the published pricing for flagship (most capable, most widely deployed) models from each major provider. These are the GPT-4-equivalent tier — the models organizations use for complex reasoning, analysis, and generation tasks.
| Provider / Model | Input (per 1M tokens) | Output (per 1M tokens) | Context Window | Enterprise Benchmark (Input) | Best Use Case |
|---|---|---|---|---|---|
| OpenAI GPT-4o | $2.50 | $10.00 | 128K | $1.75–2.10 | General enterprise; highest adoption |
| Anthropic Claude 3.5 Sonnet | $3.00 | $15.00 | 200K | $2.10–2.55 | Document analysis; regulated industries |
| Google Gemini 1.5 Pro | $3.50 | $10.50 | 2M | $2.45–3.00 | Very long context; multimodal; GCP-native |
| Anthropic Claude 3 Opus | $15.00 | $75.00 | 200K | $10.50–12.75 | Highest capability; research tasks |
| OpenAI o1 | $15.00 | $60.00 | 128K | $10.50–12.75 | Complex reasoning; math; code |
| Google Gemini Ultra 1.5 | $7.00 | $21.00 | 2M | $4.90–6.00 | Advanced multimodal; long document |
| Cohere Command R+ | $2.50 | $10.00 | 128K | $1.50–2.00 | RAG; enterprise search; structured output |
| Mistral Large 2 | $2.00 | $6.00 | 128K | $1.40–1.75 | European data residency; cost-efficient |
Efficient Model Pricing Comparison
The "efficient" tier — smaller, faster, cheaper models that trade some capability for dramatically lower cost — has become the primary deployment tier for most enterprise production AI workloads. These are the models where volume is highest and where token cost optimization matters most.
| Provider / Model | Input (per 1M tokens) | Output (per 1M tokens) | Context Window | Enterprise Benchmark (Input) | Speed |
|---|---|---|---|---|---|
| OpenAI GPT-4o mini | $0.15 | $0.60 | 128K | $0.10–0.13 | Fast |
| Anthropic Claude 3 Haiku | $0.25 | $1.25 | 200K | $0.17–0.22 | Very Fast |
| Google Gemini Flash | $0.075 | $0.30 | 1M | $0.052–0.065 | Fastest |
| Cohere Command R | $0.15 | $0.60 | 128K | $0.09–0.13 | Fast |
| Mistral Small | $0.20 | $0.60 | 32K | $0.14–0.18 | Fast |
| Meta Llama 3.3 70B (via AWS) | $0.72 | $0.72 | 128K | EDP overlay applies | Fast |
| Meta Llama 3.1 8B (via AWS) | $0.22 | $0.22 | 128K | EDP overlay applies | Very Fast |
Google Gemini Flash is the lowest-cost production-grade API model at $0.075/1M input tokens — approximately 50% less than GPT-4o mini and 70% less than Claude Haiku. For high-volume workloads where Gemini Flash capability is sufficient (extraction, classification, summarization, simple Q&A), the cost difference is material. An organization running 10B tokens/month through GPT-4o mini pays $1.5M annually; the same volume through Gemini Flash costs $750K.
"The efficient tier is where most enterprise AI spend actually lives — and where the cost differences between providers are largest. A 50% price difference on your highest-volume model is a $500K–$2M annual decision at enterprise scale."

Batch Processing Pricing: The Underused Cost Lever
| Provider / Model | Standard Input Price | Batch Input Price | Batch Discount | Latency |
|---|---|---|---|---|
| OpenAI GPT-4o (Batch API) | $2.50 | $1.25 | 50% | 24h SLA |
| OpenAI GPT-4o mini (Batch API) | $0.15 | $0.075 | 50% | 24h SLA |
| Anthropic Claude 3.5 Sonnet (Batches) | $3.00 | $1.50 | 50% | 24h SLA |
| Anthropic Claude Haiku (Batches) | $0.25 | $0.125 | 50% | 24h SLA |
| Google Batch Prediction (Gemini Pro) | $3.50 | $1.75–2.45 | 30–50% | Async; variable |
| Mistral (batch inference) | $2.00 | $1.00–1.40 | 30–50% | Async |
The 50% batch discount from both OpenAI and Anthropic is one of the most significant underutilized cost reduction opportunities in enterprise AI. Any workload that does not require a real-time response — nightly document processing, batch data extraction, end-of-day analysis runs, content generation queues — should be evaluated for batch API migration. A $2M annual synchronous API spend with 40% batch-eligible workloads translates to $400K in savings by routing batch workloads to batch endpoints.
Open-Source and Self-Hosted Models: The Ultimate Cost Floor
Self-hosted open-source models represent the theoretical cost floor for AI token pricing — the incremental cost per token approaches zero once infrastructure is provisioned. Understanding the true economics of self-hosting is essential for procurement teams evaluating build vs. buy decisions.
| Model | GPU Required (fp16) | Effective Input Cost / 1M tokens | Infrastructure Cost (monthly) | Vs. GPT-4o mini |
|---|---|---|---|---|
| Llama 3.3 70B | 4× A100 80GB | $0.02–0.06 | $6K–$14K | 87–97% cheaper |
| Llama 3.1 8B | 1× A100 40GB | $0.003–0.01 | $1.5K–$3.5K | 93–98% cheaper |
| Mixtral 8x7B | 2× A100 40GB | $0.01–0.03 | $3K–$7K | 80–93% cheaper |
| Mistral 7B | 1× A100 40GB | $0.002–0.008 | $1.5K–$3.5K | 95–99% cheaper |
| CodeLlama 70B | 4× A100 80GB | $0.02–0.06 | $6K–$14K | 60–87% cheaper |
The self-hosting economics look compelling in isolation — Llama 3.3 70B at $0.02–0.06/1M tokens versus GPT-4o mini at $0.15/1M tokens. But the comparison is incomplete without accounting for the full operational cost: dedicated ML engineering headcount ($300K–$500K annually for 2 FTE), GPU reservation costs, model fine-tuning and evaluation overhead, and the opportunity cost of deploying engineering resources to infrastructure management versus product development.
Our full analysis in the build vs. buy AI cost analysis shows that self-hosting becomes cost-effective for organizations consuming more than approximately 50–100B tokens per month at the GPT-4o mini tier — a consumption level only the largest enterprises reach in 2026. Below that threshold, managed API pricing almost always produces lower total cost when engineering time and infrastructure overhead are included.

Token Cost by Use Case: Workload-Adjusted Comparison
Raw token prices don't tell the full story — the effective cost per business outcome depends on the input/output ratio and model performance on the specific task. The table below models the effective cost per 1,000 business operations for four common enterprise AI use cases, using typical prompt structures for each.
| Use Case | Typical Tokens | GPT-4o Cost / 1K ops | Claude Haiku Cost / 1K ops | Gemini Flash Cost / 1K ops | Best Value |
|---|---|---|---|---|---|
| Contract clause extraction | 8K in / 200 out | $22.00 | $2.25 | $0.66 | Gemini Flash |
| Customer email response draft | 500 in / 300 out | $4.25 | $0.50 | $0.13 | Gemini Flash |
| Code review and suggestions | 2K in / 500 out | $10.00 | $1.13 | $0.24 | Gemini Flash |
| Long document analysis (50-page) | 40K in / 1K out | $110.00 | $11.25 | $3.30 | Gemini Flash (1M ctx) |
| Complex multi-step reasoning | 2K in / 2K out | $25.00 | $33.50 | $8.25 | GPT-4o (performance) |
The use-case analysis reveals a consistent pattern: for input-heavy workloads (document processing, contract extraction, analysis), Gemini Flash delivers the lowest effective cost by a wide margin, primarily because of its very low input price and its ability to process extremely long documents in a single call (1M context window). For output-heavy or complex reasoning workloads, GPT-4o and Claude Sonnet remain competitive because their higher capability justifies the cost premium.
Procurement Framework: Choosing the Right Platform
The token pricing comparison above, combined with enterprise committed spend discounts and cloud overlay economics, suggests the following procurement framework for AI platform selection:
- Classify workloads by input/output ratio and latency requirements. Document processing and analysis = input-heavy, async-friendly. Conversational AI = balanced, real-time required. Content generation = output-heavy, real-time.
- Select model tier per use case. Efficient models (Haiku, Flash, GPT-4o mini) for high-volume production workloads. Flagship models for complex reasoning where quality is primary criterion.
- Route batch-eligible workloads to batch APIs. 50% discount available from OpenAI and Anthropic on async workloads.
- Overlay cloud committed spend. For AWS/Azure/GCP committed organizations, route AI workloads through cloud managed services (Bedrock, Azure OpenAI, Vertex) to apply EDP/MACC discounts.
- Negotiate committed spend thresholds strategically. Aggregate token consumption across all use cases to reach a single provider's discount tier rather than spreading spend across multiple providers at sub-threshold levels.
- Evaluate open-source only above 50–100B tokens/month. Below this threshold, managed API TCO is consistently lower than self-hosted when engineering overhead is included.
Token Price Trajectory: Planning for Continued Decline
Perhaps the most important factor in AI token procurement is the consistent, dramatic price decline trajectory. GPT-4-class input pricing has declined approximately 80% in 24 months. The trend is driven by model efficiency improvements, increased compute supply (GPU manufacturing catching up to demand), and competitive pricing pressure from open-source alternatives.
Planning implications for procurement:
- Multi-year AI committed spend agreements should include price decline pass-through provisions — if the published price falls, your committed price should fall proportionally
- Annual committed spend agreements (vs. 2–3 year) preserve flexibility to capture price reductions at renewal
- Organizations that signed 2024 AI committed spend agreements at 2024 prices are now materially overpaying versus organizations that sign fresh agreements in 2026
- Budget models for AI spend should incorporate a 20–30% annual price decline assumption for production token costs, separate from volume growth assumptions
