Coverage detailsHow 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.

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.

The sequence follows explicit supersedes links. Each score is estimated for that model; a relative can inform a sparse estimate but never sets a floor, so a newer release can score below an earlier one. 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 Beam, but the public leaderboard excludes this profile until enough non-generated benchmark coverage is available. Only published rows appear above.
Beam has no verified publication yet for weight access. Its context length is not documented in the current profile. The profile records its reasoning mode as reasoning.
Limited early access through Reflection's waitlist. Reflection plans to release weights under Apache 2.0, a technical report, a model card, and developer artifacts later in October 2026; the weights are not yet publicly available. Hosted API pricing and a callable model ID are not published in the announcement.
Reflection's October 5, 2026 launch table reports these exact values for Beam, a text-only sparse MoE with 501B total and 23B active parameters. These are provider-reported preview results; the technical report, model card, and evaluation settings are still pending, so the row remains unranked. SWE-bench Pro v1 stays separate from the v2-Hard result, and Terminal-Bench 2.1 is not mapped to 2.0. The launch reports 1M effective context after continued training and 256K maximum RL rollouts, without a serving limit. No serving context is inferred from those training figures. SWE-bench Pro v2-Hard, AutomationBench public, tau3 banking, and the external-source indices are not mapped to incompatible benchmark keys.
16 of 649 tracked benchmark slots currently have displayable evidence. Missing categories stay blank.

Questions
How does Beam perform overall in AI benchmarks?
Beam has 16 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 Beam good for knowledge and understanding?
Beam has source-displayable benchmark coverage for knowledge and understanding, 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 Beam good for coding and programming?
Beam 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 Beam good for mathematics?
Beam has source-displayable benchmark coverage for mathematics, 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 Beam good for reasoning and logic?
Beam has source-displayable benchmark coverage for reasoning and logic, 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 Beam good for agentic tool use and computer tasks?
Beam 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.
Is Beam good for instruction following?
Beam has source-displayable benchmark coverage for instruction following, 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 Beam have full benchmark coverage on BenchLM?
No. Beam currently has 16 source-displayable rows across 649 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 Beam?
Beam's provider has not published a context-window limit for this exact model. The profile leaves the value unavailable instead of borrowing a number from an earlier family member or a third-party route. Maximum output length is tracked separately when the provider documents it.
