1,000,000 tokens of context. Here's what that actually unlocks.

Most models force you to choose: summarize the document or keep the detail. A 1M-token context window lets you stop choosing.

  -H "Content-Type: application/json" \
  -H "Authorization: Bearer mb-xxxxxxxx" \
  -d '{
    "model": "kimi-k3",
    "messages": [{
      "role": "user",
      "content": "Here is our entire codebase. Find every place where we use user.id directly and propose a migration path to a scoped session model.\n\n<repository dump>"
    }]
  }'

A million tokens is roughly 750,000 English words — about three full-length novels, or a large monorepo, or every support ticket your team closed this quarter. Pasted into one request. Answered in one response.

The context-window tax you've been paying

Without long context, long inputs turn into a choreography of tricks:

Chunking — slice the document, summarize each slice, then summarize the summaries. You lose cross-references the moment you cut.
Retrieval (RAG) — index everything, embed it, and hope your retrieval step pulls the right 5% back. Wrong retrieval = wrong answer, and you won't know it.
Truncation — the silent killer. The model answers confidently about a detail it never actually saw.

Every one of those is a workaround for a limitation you don't have to accept anymore.

What 1M tokens actually changes

With kimi-k3's million-token window, a different class of task stops being "impossible" and becomes "one request":

Before 1M context	After 1M context
Chunk a 300-page spec into 20 summaries	Hand the model the whole spec, ask for the cross-cutting inconsistencies
RAG over a codebase and pray retrieval finds the bug	Drop in the whole repo, ask for the fix
Summarize a 6-hour transcript in pieces	Feed the full transcript, ask for decisions + action items with verbatim quotes
Truncate a long legal doc and miss the fine print	Pass every clause, ask which ones conflict
Token-budget around a huge log dump	Paste the whole log, ask "what happened and when"

The common thread: questions that only make sense with the whole context in view at once.

A context ladder, not a single rung

One size still doesn't fit all — a million-token request costs more than an 8K one, so you shouldn't pay for what you don't need. AIBridge fronts the full gradient, so you pick per task:

Context	Model	Typical job
8K	`moonshot-v1-8k`	Quick chats, classification
32K	`moonshot-v1-32k`	Medium docs, email threads
64K	`deepseek-chat`, `deepseek-coder`	General work, coding
128K	`deepseek-v4-pro`, `qwen3-235b-a22b`, `glm-4-plus`	Reasoning over long docs
131K	`qwen-plus`	Long multilingual content
1M	`kimi-k3`	Whole repos, full transcripts, huge corpora
