AI API Pricing Comparison 2026: DeepSeek vs Kimi vs GLM vs Qwen

Per-Token Pricing Comparison

All prices shown are output token costs when accessed through TokenEase. Input tokens typically cost 50-70% less.

Model	Output Price	Context	Speed
DeepSeek V4	$0.50/M	64K	Fast
GLM-5	$0.80/M	128K	Fast
Qwen2.5	$1.20/M	128K	Medium
Doubao Pro	$1.50/M	128K	Fast
Kimi K3	$18.00/M	256K	Medium
GPT-4o (ref)	$40.00/M	128K	Fast

Note: Kimi K3 and GPT-4o prices reflect premium positioning for high-performance reasoning and long-context tasks.

Monthly Cost for Real Projects

Here is what you actually pay for a typical project generating 1 million output tokens per month:

Model	1M Tokens	Via TokenEase Starter	Via TokenEase Pro
DeepSeek V4	$500	$14.9 + $0 overage	$14.9 + $0 overage
GLM-5	$800	$14.9 + $250 overage	$14.9 + $0 overage
Qwen2.5	$1,200	$14.9 + $350 overage	$14.9 + $0 overage
Doubao Pro	$1,500	$14.9 + $500 overage	$14.9 + $0 overage
Kimi K3	$18,000	$14.9 + $50 overage cap	$14.9 + $50 overage cap
GPT-4o (ref)	$40,000	N/A	N/A

Key insight: TokenEase Starter includes 500K tokens for $14.9. Pro includes 2M tokens for $44.9. If your app uses multiple models, the included quota is shared across all of them, making the flat-rate plans extremely cost-effective for multi-model applications.

Model-by-Model Breakdown

DeepSeek V4 — Best Value

DeepSeek has aggressively priced its API to undercut competitors. At $0.50 per million output tokens, it is 80x cheaper than GPT-4o and delivers comparable performance on coding and reasoning benchmarks. The trade-off is slightly lower performance on creative writing tasks.

Best for: Cost-sensitive applications, coding assistants, data processing pipelines, backend automation.

Kimi K3 — Long-Context King

Kimi K3 commands a premium price ($18/M) but justifies it with a 256K context window and top-tier coding performance. If your application processes long documents, analyzes entire codebases, or maintains long conversation histories, K3 is worth the premium.

Best for: Document analysis, code review, legal tech, research assistants, long-form content.

GLM-5 — Balanced Performer

GLM-5 from Zhipu AI offers a strong balance of price, performance, and context length. It consistently scores in the top tier on Chinese-language benchmarks and performs well on general reasoning tasks.

Best for: Chinese-language applications, general-purpose chatbots, balanced workloads.

Qwen2.5 — Multilingual Specialist

Alibaba's Qwen2.5 shines in multilingual scenarios, supporting over 30 languages with strong performance. Its pricing is competitive for the quality offered, especially for teams building global products.

Best for: Multilingual applications, translation services, global customer support.

Doubao Pro — ByteDance Ecosystem

Doubao leverages ByteDance's massive training data to deliver strong performance in content creation, marketing copy, and social media applications. Its pricing is mid-tier but the model quality is consistently high for creative tasks.

Best for: Content creation, marketing copy, social media automation, creative writing.

How to Save 40% on AI API Costs

Most developers overpay for AI APIs because they use a single model for everything. Here is the strategy TokenEase users employ to cut costs by 40% or more:

1. Use DeepSeek V4 for routine tasks — simple Q&A, data extraction, formatting (saves 90%+ vs GPT-4o)
2. Reserve Kimi K3 for complex tasks — code review, long documents, reasoning (only when needed)
3. Use GLM-5 as the default — good performance, reasonable price, reliable uptime
4. Route by task type automatically — TokenEase lets you switch models per request with zero code changes

# Example: Route by task complexity
def get_model_for_task(prompt):
    if len(prompt) > 50000:
        return "kimi-k3"  # Long context
    elif "code" in prompt.lower():
        return "deepseek-v4"  # Coding
    else:
        return "glm-5"  # Default
