Finkkle Spaces ships two model families, each tuned for a different kind of work: * **Dufus** powers the AI coding agent. Its models are named after Earth's oceans and are optimized for reasoning over code, repos, and tool use. * **Igno** powers the assistant and automation agent. Its models are named after cloud types and are optimized for conversation, planning, and everyday task execution. Within each family, models are listed from lightest to most powerful. Higher tiers cost more per token but handle longer context, deeper reasoning, and more complex tool chains. ## Dufus: coding models Use Dufus models when you want code written, refactored, reviewed, or debugged, or when you need an agent to plan and execute multi-step work across a repository. | Model | Tier | Context window | Input (per 1M tokens) | Output (per 1M tokens) | Best for | | --------- | -------- | -------------- | --------------------- | ---------------------- | ------------------------------------------------------------- | | Arctic | Light | 64K | \$0.25 | \$1.00 | Snippets, quick explanations, small edits | | Antarctic | Balanced | 200K | \$1.50 | \$6.00 | Everyday coding, PR reviews, mid-size refactors | | Atlantic | Advanced | 500K | \$4.00 | \$16.00 | Multi-file changes, complex debugging, planning | | Pacific | Flagship | 1M | \$10.00 | \$40.00 | Whole-repo reasoning, long agentic sessions, hardest problems | ### Arctic The fastest and cheapest Dufus model. Good for autocompletion-style asks, quick "what does this function do" questions, and small localized edits. * Latency: very low * Tool use: basic (read files, run short commands) * Recommended when: you want speed and are working in a single file ### Antarctic The default Dufus model for most users. Handles typical day-to-day coding work well without the flagship cost. * Latency: low * Tool use: full plugin support * Recommended when: you are reviewing PRs, writing features, or refactoring within a module ### Atlantic Stronger reasoning and a larger context window. Better at holding a multi-file change in its head and following longer plans. * Latency: medium * Tool use: full plugin support with parallel calls * Recommended when: a task spans several files, needs careful debugging, or requires a plan before edits ### Pacific The flagship Dufus model. Highest capability, largest context, and the deepest reasoning budget. Use it when other models get stuck. * Latency: higher * Tool use: full plugin support with parallel calls and long agent loops * Recommended when: you are doing whole-repo migrations, hard architectural work, or long autonomous sessions ## Igno: assistant and automation models Use Igno models for chat, research, planning, scheduling, reminders, and running automations. Igno models are tuned for natural conversation, structured outputs, and reliable tool use across connected integrations. | Model | Tier | Context window | Input (per 1M tokens) | Output (per 1M tokens) | Best for | | ------- | -------- | -------------- | --------------------- | ---------------------- | ---------------------------------------------------------------- | | Cirrus | Light | 32K | \$0.15 | \$0.60 | Quick questions, short chats, simple automations | | Stratus | Balanced | 128K | \$1.00 | \$4.00 | Everyday assistant work, research summaries, routine automations | | Nimbus | Advanced | 400K | \$3.00 | \$12.00 | Deep research, long documents, multi-step automations | | Aurora | Flagship | 1M | \$8.00 | \$32.00 | Complex reasoning, long-running agents, high-stakes decisions | ### Cirrus The lightest Igno model. Fast, cheap, and good enough for most short conversational turns. * Latency: very low * Tool use: basic * Recommended when: you want a quick answer or a simple reminder ### Stratus The default Igno model. A solid balance of quality and cost for daily assistant use. * Latency: low * Tool use: full plugin support * Recommended when: you are summarizing content, drafting messages, or running standard automations ### Nimbus Stronger reasoning and a much larger context window. Good for research tasks that need to hold many sources at once. * Latency: medium * Tool use: full plugin support with parallel calls * Recommended when: you are doing deep research, comparing long documents, or orchestrating several plugins in one automation ### Aurora The flagship Igno model. Highest capability across reasoning, planning, and long-context understanding. * Latency: higher * Tool use: full plugin support with parallel calls and long agent loops * Recommended when: the task is high-stakes, ambiguous, or requires long autonomous execution ## Choosing between Dufus and Igno | If you are… | Use | | --------------------------------------------- | ----- | | Writing, refactoring, or debugging code | Dufus | | Reviewing a PR or planning a technical change | Dufus | | Chatting, brainstorming, or drafting text | Igno | | Running or scheduling an automation | Igno | | Doing research across many sources | Igno | | Building an agent that touches a repo | Dufus | You can switch models any time from the model picker at the top of a conversation. Automations remember the model they were created with, so change the model in the automation settings if you want it to use a different tier. ## Pricing notes * All prices above are per 1M tokens and are billed separately for input and output. * Tool use, plugin calls, and file uploads may incur additional per-call costs depending on the plugin. * Enterprise plans can pin defaults per workspace and set spend limits per model. See your workspace billing page for the exact rates that apply to your plan.
