How much does Beam cost?

Beam is published as open weights (Apache 2.0) — there is no per-token API price. You self-host the model and pay infrastructure cost (GPU rental and operating overhead). Effective cost on commodity 24-48GB GPUs typically lands at $0.10-$0.50 per million output tokens.

What is the context window of Beam?

Beam supports a context window of 1000K tokens (1,000,000 tokens) and can generate up to 33K output tokens per request.

What is Beam best for?

Beam is best for: Apache-2.0 large open model for self-hosted coding agents. It supports chat, function_calling, code, reasoning capabilities. It is open-source under the Apache 2.0 license.

Reflection AIopen-source NewOpen Source

Reflection AI's first model: a 501B-total / 23B-active sparse mixture-of-experts with 52 layers and a 1M-token effective context (256K longest used in reinforcement learning). Previewed 5 Oct 2026; weights released 16 Oct 2026 on Hugging Face under Apache 2.0 with BF16, FP8 and NVFP4 checkpoints — the permissive licence is its main selling point among large open models. Reflection's hosted API was in a free public beta with no published rate, so the row shows as self-host. Reflection reports (vendor-reported) Terminal-Bench 2.1 80.1, SWE-bench Verified 80.9 and AIME 2026 97.8; independent scoring is much weaker: Artificial Analysis Intelligence Index v5.0.1 gives it 18 (30 on the retired v4.3.2 scale), #19 of 26 open-weights models, though at only 53.7M output tokens, $0.28 per Index task and 287 tokens/s it is cheap and fast to run. Maximum output is not published; the figure shown is a placeholder.

About Beam

Beam is a open-source AI model by Reflection AI, released on October 16, 2026. It supports a context window of 1000K tokens and can generate up to 33K output tokens.

Beam is published as open weights (Apache 2.0) for self-hosting. There is no per-token API price. Cost depends on your inference infrastructure: GPU rental, throughput per GPU, and operating overhead. For commodity 24-48GB GPUs the effective cost typically lands in the $0.10-$0.50 per million output tokens range, well below the cheapest hosted alternatives.

Beam is available as an open-source model under the Apache 2.0 license, meaning you can self-host it for predictable costs or use it through API providers like Swfte Connect.
