How we ranked these

We measured effective cost per million tokens across 20 leading inference providers, weighting by real-world workload mixes: 60% chat, 25% batch, 15% streaming. We included input/output token ratios, latency-adjusted throughput, and discount tiers for committed use. Benchmarks ran on identical prompts, with cache hit rates simulated at 0%, 30%, and 60%.

We deliberately ignored one-off promotional credits, spot pricing, and academic discounts because they distort long-run procurement decisions. We also excluded providers without published SLAs or transparent pricing pages, as hidden costs and unreliable uptime undermine any per-token comparison. Finally, we did not factor in custom silicon or proprietary optimizations unless they were publicly documented and reproducible.

What to look for

When choosing between these benchmarks, focus on your actual token mix and cache behavior. A provider with lower list price but poor cache hit handling can cost 2x more in production. Also, examine throughput caps and burst limits—many cheap per-token rates assume high concurrency you may not have. Always test with your own prompts and measure end-to-end latency.

The most common mistake is comparing only the headline price per million tokens without accounting for output token weighting (often 2-4x input) and minimum spend commitments. Buyers also ignore egress fees and fine-tuning costs, which can dwarf inference charges. Another error is assuming all 'AI infra' benchmarks are apples-to-apples—they rarely specify hardware, quantization, or batch sizes. Always demand the exact configuration behind each number.

Related questions

What is the most cost-effective model for high-volume batch processing?

For batch workloads, providers like Together AI and Fireworks often undercut major clouds by 30-50% due to specialized inference stacks. However, you must verify their throughput guarantees and retry policies. A model like Llama 3.1 70B on a dedicated batch endpoint can achieve under $0.20 per million input tokens, but only with sustained usage and no latency requirements.

How does cache hit rate affect cost per token?

Cache hits can reduce effective cost by 80-90% because you pay only for output tokens and a small cache-read fee. For example, at a 60% hit rate, a model listed at $1.00/M input might effectively cost $0.40/M. Providers like OpenAI and Anthropic charge different rates for cached vs. uncached input, so optimizing prompt reuse is critical for cost control.

Which providers offer the best price for streaming responses?

Streaming often incurs a premium due to higher compute overhead. Providers like Groq and Cerebras offer extremely low per-token costs for streaming because of their custom hardware, but they have limited model availability. For general-purpose streaming, Google's Gemini models have competitive pricing, but always test real-time token generation speed—some providers throttle streaming to manage costs.

Are there hidden costs in per-token pricing?

Yes, common hidden costs include egress fees (up to $0.12/GB), minimum monthly commitments, and charges for fine-tuning or embedding storage. Some providers also bill for failed requests or retries. Always read the pricing page's footnotes—many 'per-token' prices exclude taxes and require a reserved capacity plan to achieve the advertised rate.

How do open-source models compare to proprietary APIs on cost?

Self-hosting open-source models like Llama 3.1 can be cheaper at scale—if you have the engineering talent and GPU utilization above 70%. For most teams, managed APIs from providers like Together or Fireworks offer a middle ground, with costs 50-70% lower than OpenAI's GPT-4o for similar quality. However, you lose the convenience of turnkey APIs and automatic updates.

What role does quantization play in cost per token?

Quantized models (e.g., INT8, FP8) reduce memory bandwidth and compute, lowering cost per token by 30-50% compared to FP16. Many providers now offer quantized versions of popular models at a discount, but accuracy can degrade slightly. For cost-sensitive applications, test if the quality drop is acceptable—often it's negligible for classification or extraction tasks.

How do I compare providers with different pricing structures?

Create a standardized workload with a fixed number of input and output tokens, then calculate total cost including any fixed fees. Use a tool like the LLM Cost Calculator or build your own spreadsheet. Include factors like cache hit rates, throughput limits, and regional availability. Always run a pilot with your actual data to validate the benchmark numbers.

FAQ

What is the average cost per million tokens for leading AI models in 2027?

As of 2027, leading frontier models like GPT-5 and Claude 4 cost between $2.50 and $5.00 per million input tokens and $10 to $20 per million output tokens. Smaller or open-source models can be as low as $0.10 per million input tokens. However, these prices vary widely based on cache, batch, and commitment discounts.

How do I calculate the true cost of running an AI workload?

Multiply the number of input tokens by the input price, output tokens by the output price, and add any fixed fees. Then factor in cache hit rate and throughput. For example, 1M input tokens at $1/M with a 50% cache hit costs $0.50 for input, plus output costs. Always include egress and storage if applicable.

Are there any free tiers or trial credits for AI inference?

Most major providers offer free tiers or trial credits: OpenAI gives $5 in credits, Anthropic offers $5, and Google Cloud provides $300 in credits. However, these are for evaluation only and often expire within 90 days. For production, you'll need to budget for paid usage, but some open-source providers like Together AI offer free limited API calls.

What is the difference between input and output token pricing?

Input tokens are the prompt you send, while output tokens are the generated response. Output tokens are typically 2-4 times more expensive because generating text requires more compute. For example, OpenAI charges $2.50 per million input tokens and $10 per million output tokens for GPT-4o. This asymmetry means you should optimize prompts to reduce output length.

How do I reduce my AI inference costs?

Use prompt caching to avoid reprocessing static context, choose smaller models for simple tasks, and batch requests to take advantage of lower per-token rates. Also, consider using open-source models on your own infrastructure if you have high utilization. Finally, negotiate committed-use discounts if you have predictable workloads—these can reduce costs by 30-50%.

What is the best way to benchmark AI inference cost?

Use a standardized set of prompts that represent your actual workload, including varying input lengths and output lengths. Measure both latency and throughput, and calculate cost per successful request. Run each benchmark multiple times to account for variability. Also, compare providers under identical conditions, including cache settings and concurrency levels.

Are there any hidden charges in AI API pricing?

Yes, common hidden charges include data transfer fees (egress), storage for fine-tuned models, and charges for additional features like logging or monitoring. Some providers also charge for idle compute if you reserve capacity. Always read the full pricing page and ask for a detailed quote if you have a large workload.

How do I choose between a managed API and self-hosting?

If you have less than 1 million tokens per day, managed APIs are usually more cost-effective and require no infrastructure. For high volume (over 10 million tokens per day), self-hosting with open-source models can be cheaper if you have GPU expertise. Consider total cost of ownership, including engineering time and maintenance.

What is the impact of model size on cost per token?

Larger models (e.g., 70B+ parameters) cost significantly more per token due to higher compute and memory requirements. For example, a 70B model might cost $1.00 per million input tokens, while a 7B model costs $0.10. However, larger models often require fewer tokens for the same task, so evaluate cost per successful task, not just per token.
