roadmodel 0.1.0

BYO-key CLI that recommends the right AI model, platform, and settings for a prompt.

roadmodel

A BYO-key command-line tool that recommends which AI model on which platform with which settings for a given prompt. Point it at a task description, and it returns a six-field block — MODEL / PLATFORM / MAX MODE / THINKING / CONVERSATION / RATIONALE — grounded in a bundled benchmark and pricing catalog (Cursor pricing, Artificial Analysis, LiveCodeBench, τ²-bench, SWE-bench, MMMU, LMArena) and filtered against your own subscriptions and API keys. Built for developers who use several AI subscriptions (Claude Code, Cursor, Codex / ChatGPT, raw provider APIs) and want a deterministic answer to "what should I use for this?" instead of guessing.

Install

pip install roadmodel

Python 3.11 or newer.

Quickstart

Three steps from a fresh install to a parsed recommendation block.

1. Export an API key for any one of the three providers. Anthropic shown here; OpenAI and Google work the same way — see docs/byo-key-setup.md for the full guide.

export ANTHROPIC_API_KEY=sk-ant-...

2. Run roadmodel recommend once to bootstrap your user-context file. On the first invocation, the CLI writes a copy of the bundled template to ~/.config/roadmodel/user-context.md (or $XDG_CONFIG_HOME/roadmodel/user-context.md when XDG_CONFIG_HOME is set), prints a one-line stderr notice telling you what it did, and exits without calling the provider. Open the file and replace the $XXX and Yes/No placeholders with your actual subscription amounts and API-key state. The full field-by-field walk-through lives in docs/user-context-setup.md.

roadmodel recommend "Refactor auth middleware across 12 files"
# stderr: Created /home/you/.config/roadmodel/user-context.md from
#         bundled template. Edit it with your real subscription
#         state, then re-run.

$EDITOR ~/.config/roadmodel/user-context.md

3. Re-run. With the user-context filled in, the same command calls your chosen provider and prints a parsed six-field block:

roadmodel recommend "Refactor auth middleware across 12 files"

MODEL: claude-opus-4-7
PLATFORM: Claude Code
MAX MODE: On
THINKING: High
CONVERSATION: New
RATIONALE: Coding PRIMARY with cross-file scope and High complexity.
Opus 4.7 is S-tier on coding-agent benchmarks and the only model in
the catalog rated S for long-context recall. PLATFORM Claude Code
is funded by claude.ai Max ($0 marginal); THINKING High per the
selection-algorithm rule for High-complexity coding.

Pass --json to emit the same fields as machine-readable JSON, or --file PATH to read the prompt from disk.

BYO-key setup

roadmodel ships with no provider key built in — it calls your Anthropic / OpenAI / Google account on every recommendation and charges your account. Set any one of the three environment variables and the CLI auto-selects that provider:

Provider	Env var
Anthropic	ANTHROPIC_API_KEY
OpenAI	OPENAI_API_KEY
Google	GOOGLE_API_KEY

The full guide — generating keys in each provider's console, storing them in a shell profile or ~/.config/roadmodel/config.toml, precedence rules, and verifying with a smoke call — is docs/byo-key-setup.md.

User context setup

roadmodel reads a per-user Markdown file describing your active subscriptions, API keys, platform preference order, and budget posture so the <access-selection> step can pick a platform and thinking level alongside the model. The resolved default path is ~/.config/roadmodel/user-context.md (or $XDG_CONFIG_HOME/roadmodel/user-context.md when XDG_CONFIG_HOME is set); override it for a single run with --user-context PATH or for a whole shell with ROADMODEL_USER_CONTEXT=PATH. The full walk-through — first-run bootstrap, full precedence chain, field-by-field schema, when to update — is docs/user-context-setup.md.

Subcommands

Command	What it does
roadmodel recommend PROMPT	Recommend a six-field block for the given prompt.
roadmodel recommend --file P	Same, but read the prompt text from file P.
roadmodel recommend --json	Emit the parsed six fields as JSON instead of the labeled text block.
roadmodel recommend --provider	Override which provider answers (anthropic / openai / google).
roadmodel recommend --model	Override the specific model ID on the chosen provider.
roadmodel recommend --user-context PATH	Override the user-context.md location for this invocation.
roadmodel catalog show	Print the bundled model-selector.txt (use --doc tier-cost-scale for the price doc).
roadmodel catalog path	Print the on-disk path of the bundled catalog document (same --doc flag).
roadmodel context show	Print the resolved user-context.md file.
roadmodel context path	Print the resolved user-context.md path (or the bootstrap target if missing).
roadmodel context init	Bootstrap user-context.md from the bundled template (--force to overwrite).
roadmodel version	Print the installed version.

How it works

The CLI ships three documents as package data: model-selector.txt (the selection algorithm and the per-model access-methods catalog), model-tier-cost-scale.md (per-token prices and tier ratings), and user-context.example.md (the user-state template). At recommendation time, roadmodel recommend reads your filled-in user-context.md from disk, concatenates the three docs into a single system prompt, and calls the provider you configured. The provider returns a MODEL / PLATFORM / MAX MODE / THINKING / CONVERSATION / RATIONALE block following the <output-format> specification inside model-selector.txt. MODEL is chosen by <selection-algorithm> against your prompt's task category and complexity; PLATFORM and THINKING are filled by the <access-selection> step, which depends on the subscriptions and API-key state declared in your user-context.md.

Project status

roadmodel is in Phase 1 of the public ROADMAP.md — the open-source CLI release. Phase 2 adds an MCP server alongside the CLI; later phases add a hosted SaaS at roadmodel.ai. The project was previously named model-selector and was renamed to roadmodel ahead of the public release; the canonical bundled-doc filename model-selector.txt is preserved so existing references in other projects keep working. Until v1.0.0, expect breaking changes to the CLI surface as Phase 2 lands.
