DeepSeek v4 PRO KIMI K2.6 GLM 5.1 API KEY 50$

🔥 $50 Fireworks AI API Key — DeepSeek V4 PRO / Kimi K2.6 / GLM 5.1

Selling a working Fireworks AI API key, prepaid for $50. This provides full access to the platform used to run the top open-source models of 2026. One key, and your OpenCode, Cursor, Cline, or any other agent works at the level of closed frontier LLMs, but at an open-source price and without a card.

Three models worth buying:

DeepSeek V4 Pro — the open-source leader for complex code and agents. It offers a million context tokens, is MIT-licensed, and handles multi-step tasks in the terminal with confidence. If you´re building an AI agent for refactoring or working with large repositories, this is your choice.

Kimi K2.6 — the flagship Moonshot AI. Speed: ~85 T/s, 256K context, tailored for agent orchestration. Handles long sessions with dozens of tool calls without losing the thread of the conversation. Modified MIT – suitable for embedding in commercial projects.

GLM 5.1 – a reasoning model from Zhipu AI with 200K context. Strong in systems engineering and planning. If an agent needs to not just write code but think through the architecture down to the last detail, GLM handles the task more reliably than many competitors.

All three support tool calling out of the box. The agent can immediately invoke terminal commands, search code, and work with Git – all through the standard OpenAI-compatible API.

Connection to OpenCode TUI (literally 3 clicks):

OpenCode natively supports Fireworks AI – no need to manually edit configs or specify base_url.

1. At the bottom of the OpenCode window, click "Select Model" (or Ctrl ´).
2. In the "Manage Models" window that opens, click "Connect Provider."
3. Enter Fireworks AI in the search bar and select it from the list.
4. Paste the received API key into the "Fireworks AI API Key" field and click "Submit."
5. Done—DeepSeek V4 Pro, Kimi K2.6, GLM 5.1, and dozens of others will appear in the list of models. Choose the one you need and start working.

That´s it. No JSON configs, no fiddling with environment variables. OpenCode will automatically pick up the endpoint and context limits.

It also works everywhere:

The same key can be pasted into Cursor, Cline, Kilo Code, Continue.dev, Claude Code, or your own scripts. The main thing is that the provider supports an OpenAI-compatible API, and Fireworks does. Change one line of the base_url file, and your entire setup works on DeepSeek V4 Pro or Kimi K2.6.

What you get after payment:

A working Fireworks AI API key with full access to the model catalog. Pay only for the tokens you spend—no subscription fees or mandatory deposits. Prompt autocaching works out of the box, and the price is lower for recurring requests.

I check the key before sending it. If you have any questions, let me know—I´ll help you implement it into your setup.
