check_opencore_models

Tools for discovering and comparing free/cheap AI models across OpenCode (Zen & Go plans) and OpenRouter.

Overview

Script	Provider	Purpose
opencode_price_estimator.py	OpenCode Zen/Go	List cheap models, compare Zen vs Go plans, estimate costs
openrouter_cheap_models.py	OpenRouter	List cheap models by category (text, embedding, transcription)

---

opencode_price_estimator.py

Fetches models from the OpenCode Zen API, enriches them with pricing scraped from official docs, and filters/estimates costs.

Data sources:

• API: https://opencode.ai/zen/v1/models
• Zen docs: https://opencode.ai/docs/zen
• Go docs: https://opencode.ai/docs/go/
• Local cache: opencode_prices.json

What it does:

• Lists all models with input/output pricing per million tokens
• Filters by price range (min/max)
• Segments by provider: Zen (pay-as-you-go), Go (subscription), or both
• Estimates cost for a given token usage (input + output)
• Compares Zen pay-as-you-go vs Go subscription value ($10/mo, ~$60 estimated usage)
• Scrapes and saves updated pricing to local JSON

Examples

# List all models under $2/1M tokens
python opencode_price_estimator.py

# Only free models
python opencode_price_estimator.py --threshold 0.00

# Only Zen models, max $1/1M
python opencode_price_estimator.py --provider zen --threshold 1.00

# Show Zen and Go tables separately
python opencode_price_estimator.py --segment

# Estimate cost: 5M input tokens + 2M output tokens
python opencode_price_estimator.py --estimate 5000000 2000000

# JSON output for scripting
python opencode_price_estimator.py --output json

# Refresh prices from OpenCode docs
python opencode_price_estimator.py --update-prices

Flags

Flag	Description	Default
--threshold	Max price ($/1M tokens)	2.00
--min	Min price ($/1M tokens)	—
--max	Max price ($/1M tokens, overrides --threshold)	—
--provider	Filter: all, zen, go	all
--segment	Show separate Zen/Go tables	false
--estimate	Cost estimate: <input_tokens> <output_tokens>	—
--output	Format: table, json	table
--update-prices	Scrape docs and update opencode_prices.json	false
--prices-file	Custom prices JSON path	opencode_prices.json
--go-value	Estimated Go monthly usage value ($)	60.0

openrouter_cheap_models.py

Fetches models from OpenRouter API and filters cheap/free ones. Results are segmented by modality.

Data sources:

• Text models: https://openrouter.ai/api/v1/models
• Embedding models: https://openrouter.ai/api/v1/embeddings/models
• Transcription models: https://openrouter.ai/api/v1/models?output_modalities=transcription

What it does:

• Lists text, embedding, and transcription models with pricing
• Handles per-token pricing (text/embedding) and per-second pricing (audio/transcription)
• Filters by price range (min/max)
• Free models and negative prices (variable pricing) are handled specially

Examples

# List models under $0.03/1M tokens
python openrouter_cheap_models.py

# Only free models
python openrouter_cheap_models.py --threshold 0.00

# Models between $0.01 and $0.10/1M
python openrouter_cheap_models.py --min 0.01 --max 0.10

# JSON output
python openrouter_cheap_models.py --output json

Flags

Flag	Description	Default
--threshold	Max price ($/1M tokens)	0.03
--min	Min price ($/1M tokens)	—
--max	Max price ($/1M tokens, overrides --threshold)	—
--output	Format: table, json	table

Data

opencode_prices.json is auto-generated by opencode_price_estimator.py --update-prices. It contains scraped pricing with source tags (zen, go, both) and context lengths.
