Laguna M.1 is the flagship coding agent model from [Poolside](https://poolside.ai/), optimized for complex software engineering tasks. Designed for agentic coding workflows, it supports tool calling and reasoning, with a 256K...
Real jobs this model can take on, based on what it can read and how it’s priced.
Work through a hard problem step by step, not just answer it
step-by-step reasoning
Hold an entire codebase in one request and answer across it
262K-token context
Standard OpenAI fields, grouped by what they control. Anything not listed is accepted and ignored.
The hard numbers — what it can take in, what it can give back, and where it stops.
No. Poolside has retired Laguna M.1 and it can no longer be called through OpenDunes. This page is kept as a record of what it did. The rest of the catalog is unaffected — every model still listed is billed per token in dinars from the same balance.
Laguna M.1 reads up to 262K tokens in one request, and writes back up to roughly 25,000 words at once.
It reads text and replies with text. It also supports calling your own tools, step-by-step reasoning and streaming its answer as it writes.
Yes. Top up your OpenDunes balance in dinars with a CIB or Edahabia card, then spend it on any model in the catalog from that same balance. No foreign card, no currency conversion, no subscription. Laguna M.1 is not among them any more, but its replacements from the same lab are.
Laguna M.1 is built by Poolside, released on Apr 28, 2026. OpenDunes served it unchanged — same model, same weights, billed in dinars — until the lab retired it.
