Ultra plan

Unlimited Kimi K3.1 and DeepSeek V4.1 Flash for $200 a month, subject to rate limits

The Ultra plan is $200 a month and limited to 1,000 subscriptions. It removes the token meter on Kimi K3.1 and DeepSeek V4.1 Flash.

Unlimited does not mean unthrottled. Each subscription has per-minute limits on uncached input and output tokens for each model, and requests can return 429 when Morph is at capacity. See Rate limits.

​

What the plan covers

Model	API ID	On the plan
Kimi K3.1	morph-kimik31	No token meter
DeepSeek V4.1 Flash	morph-dsv41flash	No token meter
DeepSeek V4.1 Flash 1017	morph-dsv41flash-1017	No token meter
Every other model, including morph-dsv41flash-abliterated		Per token at list price

The plan includes no credits. Other models draw down any credits you have bought, then bill to your card at list price. There is no monthly token cap on the included models.

​

Rate limits

Two kinds of limit apply to the included models.

Per-minute rate limits. Each subscription has one rate limit on uncached input tokens and another on output tokens for each model, so no single account can crowd out the rest. There is no limit on total tokens, only on how fast you use them.

Model	Uncached input tokens per minute	Output tokens per minute
Kimi K3.1	72,870	6,162
DeepSeek V4.1 Flash, both versions	2,103,237	76,559

Cached input does not count toward either limit. A request bigger than a limit still runs, and your next request waits until that limit has caught up. Output counts when a response finishes. The 429 states the limit you reached, and Retry-After says how long to wait. The two DeepSeek V4.1 Flash versions share one set of limits.

Capacity. The plan does not reserve capacity. When Morph is at capacity, requests can return 429 until capacity frees up.

Handle both the same way: retry with exponential backoff, and honor Retry-After when it is present. The OpenAI and Anthropic SDKs do this for you.

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.MORPH_API_KEY,
  baseURL: "https://api.morphllm.com/v1",
  maxRetries: 5,
});

For reserved capacity with an availability SLA, use dedicated endpoints.

​

Get the plan

1. Open Billing.
2. Choose Ultra under Subscription.
3. Complete checkout.

Subscribe from the account whose API keys should be covered. A personal subscription covers your personal API keys. An organization subscription is billed per member, covers the organization’s API keys, and pools all members under one set of rate limits.

If you already have a subscription, the new plan replaces it, and the unused part of your current plan comes off your first charge. Remaining subscription credits are not carried over.

​

Use it with a coding agent

After checkout, Set up Morph Ultra has a copy-paste prompt for Claude Code, Codex, Pi, OpenCode, T3 Code, OMP, and Hermes Agent. Paste the prompt into any coding agent and it configures that tool for you.

To configure Claude Code by hand, point it at Morph with the included models:

export ANTHROPIC_BASE_URL="https://api.morphllm.com"
export ANTHROPIC_AUTH_TOKEN="YOUR_MORPH_API_KEY"
export ANTHROPIC_MODEL="morph-kimik31"
export ANTHROPIC_SMALL_FAST_MODEL="morph-dsv41flash"

See Claude Code & Codex for persistent settings and Codex setup.

Cancel

Cancel from Billing. After the plan ends, usage on these models bills per token.
