2 published rows leave some tracked benchmark slots empty.
Decision snapshot
Each value carries a field reference instead of floating alone. Markers compare this model with the current ranked and priced catalog; they are not absolute quality thresholds.

How much of this is verified
Coverage is split by category so a strong number never hides a thin evidence base. Verified means the row is tied to a published source; provisional rows remain visible but separate.

Category score record
Scores and ranks appear only where published evidence can be displayed. The table keeps the score, weight, cohort, and evidence state together.

Benchmark ledger
Coding opens by default. The marker compares each value with the best source-verified result in the catalog; provisional leaders do not set the reference. Expand the remaining categories for every published row.

Lineage
The sequence follows explicit supersedes links. A successor's displayed score stays at least 0.1 points above its predecessor; raw benchmark rows do not move. Scores and prices remain blank when the corresponding public row or first-party rate is unavailable.

How to read this profile
The visual layer above carries the decisions. These notes preserve the model, ranking, coverage, and family context behind the numbers.
We track Quasar 438B, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Quasar 438B is a proprietary model with a 1M context window. It uses an explicit reasoning mode, which can improve complex problem solving while adding latency and token use.
Available through the OpenAI-compatible CompactifAI API as `quasar-438b`. The API supports chat completions, tool calling, structured output, and always-on reasoning with `high` and `max` effort; `max` is the default.
Multiverse Computing's September 2, 2026 launch page reports Quasar 438B at 69.3 on Terminal-Bench 2.1. We keep the result display-only and leave the model unranked until independent benchmark coverage clears the ranking gate. The supplied external profile informs a separate internal calibration signal and reports a 1 million-token context window; first-party model documentation does not yet publish an exact context limit.
2 of 416 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Frequently asked questions
How does Quasar 438B perform overall in AI benchmarks?
Quasar 438B has 2 source-displayable benchmark rows, but it does not qualify for a public overall rank. The available rows remain visible by category without being converted into a site-wide score. Missing evidence stays blank instead of being estimated from an earlier model.
Is Quasar 438B good for coding and programming?
Quasar 438B has source-displayable benchmark coverage for coding and programming, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Is Quasar 438B good for agentic tool use and computer tasks?
Quasar 438B has source-displayable benchmark coverage for agentic tool use and computer tasks, but the public category table does not assign it a rank there. The individual rows remain available for inspection. A missing category position means the evidence threshold was not met; it does not convert the model's unmeasured work into a zero.
Does Quasar 438B have full benchmark coverage on BenchLM?
No. Quasar 438B currently has 15 source-displayable rows across 416 tracked benchmark slots. The profile exposes published, non-generated evidence and leaves missing categories blank until an exact evaluation is available. Coverage describes how much was measured; it is not a penalty added to an individual benchmark result.
What is the context window size of Quasar 438B?
Quasar 438B has a documented context window of 1M. That figure is the maximum combined prompt and retained-conversation space reported for this exact model; it is not the maximum output length. The profile keeps output limits separate because providers often publish those limits independently.
