Using PostQode with Free, Budget, and Flagship Models
Optimizing AI model costs is essential for sustainable, high-velocity development. PostQode gives you complete freedom to connect any AI provider or model tier—ranging from 100% free and open-source models to ultra-budget high-speed models and frontier reasoning engines.
This guide covers all supported model families, cost tiers, and architectural strategies to get the highest coding performance while keeping costs minimal.
Model Tiers Overview
PostQode supports models across four distinct operational and cost tiers:

Understanding General Model Naming Conventions
Because AI providers frequently release new revisions, snapshot dates, and preview tags, PostQode automatically resolves both general family aliases and specific version identifiers:
General Model Families
claude-*(Anthropic): Resolves across Sonnet, Haiku, and Opus tiers with native support for Prompt Caching and Thinking Budget tokens.gpt-*ando*(OpenAI): Resolves flagship (gpt-5.x,gpt-4o), budget (mini,nano), and reasoning series (o3-mini,o4-mini).gemini-*(Google): Resolves Flash (speed/budget) and Pro (deep reasoning/large context) tiers.deepseek-*(DeepSeek): Resolvesdeepseek-chat(V3/V4 non-reasoning) anddeepseek-reasoner(R1 chain-of-thought).qwen-*(Alibaba Cloud / Open Weights): Resolves dedicated Coder editions (qwen2.5-coder-32b,qwen3-coder-plus).llama-*(Meta): Resolves open-weights Maverick, Scout, and Versatile editions.mistral-*/devstral-*/codestral-*(Mistral AI): Resolves developer-centric code models.kimi-*(Moonshot): Resolves agentic long-context models.
In PostQode Settings (), clicking the model dropdown or refreshing provider models dynamically fetches the latest supported models directly from your configured provider.
PostQode Cost Optimization Strategies
1. Dual Mode Model Allocation (Plan vs Agent)
PostQode's Dual Mode architecture allows you to decouple planning from execution:
- Plan Mode: Configure a deep-reasoning or low-cost model (e.g.
deepseek-reasoner,gemini-2.0-flash-thinking, oro3-mini). Explore architecture, outline steps, and inspect files without writing code changes. - Agent Mode: Configure a fast, surgical code generation model (e.g.
claude-3-5-sonnet,qwen2.5-coder-32b, orgpt-4o-mini) to apply diffs and execute terminal commands.
Configure this in Model Configuration under Plan Mode Model and Agent Mode Model.
2. Prompt Caching
PostQode supports native prompt caching for Anthropic, OpenAI, DeepSeek, and LiteLLM:
- Repeated codebase context, system instructions, and tool definitions are cached on provider servers.
- Reduces input token costs by up to 90% and cuts response latency in half.
3. Targeted Context Mentions
Instead of including entire large files, reference only what PostQode needs:
@src/auth/jwt.ts:40-85
@src/types/user.ts
This prevents context bloat and preserves tokens for the actual generation phase.
4. Automatic Context Compaction (/compact)
When conversations grow long, trigger /compact or enable Auto-Compact in settings. PostQode summarizes earlier conversation turns into a dense executive summary, freeing up context window capacity without losing essential facts.
5. Built-in Specialized Agents
For exploratory or domain-specific tasks (such as grepping logs or testing API endpoints), dispatch a specialized agent (such as Core Agent or Web Agent). Specialized agents execute focused tasks and prevent large intermediate outputs from polluting your primary task history.
