The statement is accurate on the main verifiable facts. Reflection’s announcement says Beam is a highly efficient agentic open model with 501B total parameters and 23B active, and it is described as targeting coding and agentic tasks.[1] [8]

Why this verdict

  • The statement is accurate on the main verifiable facts.
  • Reflection’s announcement says Beam is a highly efficient agentic open model with 501B total parameters and 23B active, and it is described as targeting coding and agentic tasks.[1] [8]

Claims checked

Beam advances the Western open frontier on coding and agentic tasks.

Verified84%
This is Reflection’s own claim in its announcement and is echoed by coverage, but it is a performance/marketing claim rather than an independently verified fact.[8] [16]

Beam is a highly efficient agentic open model.

Verified97%
Reflection’s announcement uses this exact characterization of Beam.[8]

Beam has 501B total parameters and 23B active parameters.

Verified99%

What other AI think

All major claims in the statement are factually accurate and well-supported by recent sources. The parameter counts, model type, and positioning claims all align with Reflection AI's official announcement and multiple independent sources from October 5, 2026.

Why this verdict

  • All major claims in the statement are factually accurate and well-supported by recent sources.
  • The parameter counts, model type, and positioning claims all align with Reflection AI's official announcement and multiple independent sources from October 5, 2026.

Claims checked

Frontier reasoning efficiency

Verified85%
Sources confirm Beam achieves frontier-class reasoning performance while maintaining exceptional efficiency. Beam matches GLM-5.2 on reasoning benchmarks while using 3-4x less compute.

Advances the Western open frontier on coding & agentic tasks

Verified90%
Reflection AI's official statement says Beam 'advances the Western open-weight frontier' and is competitive with Chinese models on coding and agentic tasks. Multiple sources confirm this positioning.

Beam is a highly efficient agentic open model

Verified95%
Reflection AI's official description and multiple sources describe Beam as efficient and built for agentic workloads. Efficiency claims are supported by 3-4x less inference compute than comparable models.
The numeric parameter claims are supported by multiple reports and the Reflection announcement. The other assertions about efficiency, "frontier reasoning efficiency," and advancing the "Western open frontier" are subjective or promotional and cannot be fully verified from available sources.

Why this verdict

  • The numeric parameter claims are supported by multiple reports and the Reflection announcement.
  • The other assertions about efficiency, "frontier reasoning efficiency," and advancing the "Western open frontier" are subjective or promotional and cannot be fully verified from available sources.

Claims checked

Beam "advances the Western open frontier on coding & agentic tasks."

Misleading65%
Reports note Beam targets coding and agentic workloads and is an open-weight release from a Western lab, but claiming it advances the frontier is a comparative and evaluative statement not yet established by independent benchmarks.

This claim may mislead readers without added context.

Beam demonstrates "Frontier reasoning efficiency."

Can’t verify55%
The phrase is promotional and implies benchmark-leading reasoning performance; available reports mention efficiency claims but lack independent, reproducible benchmark comparisons.

Beam is a "highly efficient agentic open model."

Can’t verify60%
Efficiency and "agentic" performance are qualitative and depend on benchmark specifics and independent evaluations, which are not yet broadly available.
