Run it on your own hardware
Weights are the sizes of the files a source lists, or an estimate from the parameter count where none does. Memory is an estimate: weights plus KV cache plus 512 MiB and 5 percent of the weights for runtime buffers. Check it against your hardware.

Use it from your harness
Set up for Abacus with the model thinkingmachines/Inkling. Each endpoint page has the same setup for its own address.
OpenCode
Put this in opencode.json in your project folder:
{
"$schema": "https://opencode.ai/config.json",
"provider": {
"abacus": {
"npm": "@ai-sdk/openai-compatible",
"name": "Abacus",
"options": {
"baseURL": "https://routellm.abacus.ai/v1",
"apiKey": "{env:ABACUS_API_KEY}"
},
"models": {
"thinkingmachines/Inkling": {
"name": "Inkling",
"limit": {
"context": 1048576,
"output": 471859
}
}
}
}
}
}- OpenCode reads any OpenAI-compatible address through the @ai-sdk/openai-compatible package, and an address that speaks the Responses API through @ai-sdk/openai.
From OpenCode documentation, read .
Pi
Put this in ~/.pi/agent/models.json:
{
"providers": {
"abacus": {
"baseUrl": "https://routellm.abacus.ai/v1",
"api": "openai-completions",
"apiKey": "$ABACUS_API_KEY",
"models": [
{
"id": "thinkingmachines/Inkling"
}
]
}
}
}- The apiKey field can name an environment variable as $NAME.
From Pi documentation, read .
Codex
Codex speaks only the Responses API, and Abacus documents no Responses address. A gateway that offers one can sit in between.
- Codex speaks the Responses API only: responses is the one supported wire API of a custom provider. Ollama and LM Studio are built in and start with --oss.
From Codex documentation, read .
Claude Code
Claude Code sends Anthropic Messages requests, and Abacus documents no such address. A gateway that translates to that API can sit in between.
- Claude Code sends Anthropic Messages requests to ANTHROPIC_BASE_URL. Anthropic says it does not support routing Claude Code to models other than Claude through any gateway, so some features may not work with another model.
