DeepSeek V4 Pro, Kimi K3, MiniMax M3 & GLM-5.2: 40% Off

Which 40%-off AI model should you choose?

Choose DeepSeek V4 Pro when price-efficient reasoning is the priority. Choose Kimi K3 for very large repositories, document collections, and long tool loops. Choose MiniMax M3 when the workload combines code with images, video, or computer-use tasks. Choose GLM-5.2 for sustained engineering projects that must preserve constraints over many steps.

That is the short answer. The better production decision is to run the same representative prompt set against two or three candidates, then compare quality, latency, and total output-token cost. A lower input price does not help if a model needs substantially more retries or generates unnecessarily long answers.

DeepSeek V4 Pro: low-cost reasoning with a 1M context

DeepSeek V4 Pro is the value option in this group. DeepSeek's official documentation lists a one-million-token context window, up to 384K output tokens, thinking and non-thinking modes, JSON output, tool calls, prefix completion, and FIM completion.

At the current APIMaster promotional rate, deepseek-v4-pro costs $0.261/M input and $0.522/M output, versus the official $0.435/$0.87 rate. That makes it a practical starting point for reasoning-heavy automation, mathematics, code review, batch analysis, and agents where token volume matters.

DeepSeek also announced that the older deepseek-chat and deepseek-reasoner aliases will be discontinued on July 24, 2026. New integrations should use the explicit deepseek-v4-pro model ID instead of building around a legacy alias.

Kimi K3: one-million-token context for coding and knowledge work

Kimi K3 is Moonshot AI's flagship for software engineering, knowledge work, and deep reasoning. Its 1,048,576-token context window is designed for large repositories, long research inputs, extensive tool histories, and tasks that need more continuity than a conventional chat session.

The current 40%-off APIMaster route is $1.80/M input and $9.00/M output, compared with Kimi's official $3/$15 price. Kimi also publishes a lower cache-hit input rate, so applications with stable system prompts or repeated long prefixes should measure cache behavior as well as the headline rate.

Kimi K3 is the strongest fit here when a single task must retain a very large amount of working context. For smaller prompts, benchmark it against the cheaper DeepSeek and MiniMax routes before making it the default.

MiniMax M3: coding, agents, and native multimodality

MiniMax positions M3 as a frontier coding and agentic model built on MiniMax Sparse Attention (MSA). It supports up to 1M tokens of context, native image and video understanding, tool-driven workflows, and computer-use scenarios.

At APIMaster's current promotional rate, minimax-m3 costs $0.18/M input and $0.72/M output, down from $0.30/$1.20. It is the lowest-priced input route among the four models in this offer.

MiniMax M3 is worth testing for repository work that includes screenshots, diagrams, recorded workflows, or long video material. The official API uses the MiniMax-M3 name, while APIMaster accepts the marketplace model ID shown on the live card; minimax-m3 is the normalized ID used in the example below.

GLM-5.2: long-horizon engineering with controllable effort

GLM-5.2 is Z.ai's flagship for long-horizon work. It combines a 1M-token context window, up to 128K output tokens, function calling, structured output, context caching, MCP support, and multiple reasoning-effort levels.

The 40%-off APIMaster route costs $0.84/M input and $2.64/M output, compared with the official $1.40/$4.40 rate. It is aimed at tasks that must keep architectural rules, interface contracts, and project history intact across extended implementation and debugging sessions.

Choose GLM-5.2 when the main risk is not one difficult answer but gradual loss of constraints during a long agent run. Its effort controls also let teams trade latency and token use for stronger reasoning on the hardest steps.

Why use APIMaster for these four models?

One OpenAI-compatible API key

APIMaster provides one base URL and one key for DeepSeek, Kimi, MiniMax, GLM, Claude, GPT, Gemini, and other model families. You can compare models without maintaining separate provider accounts, SDKs, balances, and billing integrations.

Live price and route comparison

The APIMaster marketplace shows active channels, input and output prices, availability, latency data, and route history. The 40% offer is visible at route level, so you can confirm the current price before a batch job or production rollout.

Model fingerprint verification

Low-cost API routes sometimes create a harder question: is the endpoint serving the model it claims? APIMaster's free AI model fingerprint tester examines behavioral signals to help identify silent model substitution before you scale usage.

Pay as you go and switch without rewriting

Fund one balance, create a key, and change the model field when your workload changes. This is useful for routing inexpensive batch work to MiniMax or DeepSeek while reserving Kimi or GLM for long-context engineering tasks.

How to use DeepSeek, Kimi, MiniMax, or GLM with one API

Install the OpenAI SDK, create a key in the APIMaster console, and use the model ID shown in the marketplace:

from openai import OpenAI

client = OpenAI(
    api_key="YOUR_APIMASTER_KEY",
    base_url="https://apimaster.ai/v1",
)

response = client.chat.completions.create(
    model="deepseek-v4-pro",  # kimi-k3, minimax-m3, or glm-5.2
    messages=[
        {
            "role": "user",
            "content": "Review this migration plan and list the three highest risks.",
        }
    ],
)

print(response.choices[0].message.content)

Model-specific parameters can differ. Start with the common Chat Completions fields, then add thinking, multimodal, or effort controls only after checking the selected model's documentation and testing the request against the live route.

How to get the 40% discount

FAQ

Are DeepSeek V4 Pro, Kimi K3, MiniMax M3, and GLM-5.2 really 40% off?

Yes. On July 20, 2026, APIMaster's live marketplace showed 40%-off routes for all four models. Discounts and route availability are dynamic, so confirm the current card before use.

Which model is cheapest in this promotion?

MiniMax M3 has the lowest promotional input price at $0.18 per million tokens. DeepSeek V4 Pro has the next-lowest input price at $0.261/M. Total workload cost also depends on output length, retries, caching, and whether the model completes the task successfully.

Which model is best for coding agents?

All four target coding or agent workflows. DeepSeek V4 Pro emphasizes low-cost reasoning, Kimi K3 emphasizes very large working context, MiniMax M3 combines coding with native multimodality, and GLM-5.2 emphasizes reliable long-horizon engineering. Test your own repository and tool loop instead of relying on a single benchmark.

Can one APIMaster key call all four models?

Yes. Use the same OpenAI-compatible key and base URL, then change the model value to the ID shown in the marketplace.

How can I check that a discounted route serves the advertised model?

Run representative prompts and use APIMaster's model fingerprint tester before sending production traffic. Continue monitoring quality and route history after deployment.
