Overview
What Holo4 is
Holo4 is a family of agentic vision-language models from H Company, not a finished task app. The company offers a 27B dense model and a 35B-A3B mixture-of-experts model. Both are designed to move among graphical interfaces, code execution, MCP tools, and APIs in one workflow across desktop, web, Android, and business systems.
H Company reports strong OSWorld and automation benchmark results, but those are vendor-measured or cross-source figures under named harnesses. Its own article notes a gap from stronger closed models on long OSWorld 2.0 workflows. Teams choosing Holo4 should evaluate task success, recovery, permission boundaries, and latency on their actual environment. API access and downloadable weights offer two deployment paths, with different infrastructure and licensing implications.
Use cases
Who Holo4 is best for
The strongest fit depends on the job you need the product to complete, not the size of its feature list.
Enterprise automation teams
Prototype repetitive desktop, web, or mobile workflows within a controlled test environment.
Model operators
Evaluate downloadable weights where hosting control and the applicable license matter.
Capabilities
Core Holo4 features
Multi-interface control
Holo4 can click and type, write and run code, and call MCP or API tools.
Two model sizes
Choose the 27B dense model for the reported stronger long-task accuracy or 35B-A3B for a cheaper, faster profile.
Broad environments
The release describes desktop, web, Android, code sandbox, and business API tasks.
API and weights
H Models API hosts both sizes; multiple weight formats are published on Hugging Face.
Long context
H Company lists a 256K-token context window for both models.
Process
How the Holo4 workflow works
Step 1
Choose the interface mix
List exactly which screens and structured tools the agent will need to complete one business task.
Step 2
Run in a sandbox
Give temporary accounts, least-privilege credentials, and a recoverable environment.
Step 3
Compare both sizes
Measure the same success criteria and cost on 27B and 35B-A3B.
Step 4
Review actions
Log intermediate tool calls and screen steps, then add approvals for irreversible changes.
Cost
Holo4 pricing and free plan
H Company publishes H Models API token rates: Holo4 27B at $0.40 input and $3.00 output per million tokens; Holo4 35B-A3B at $0.30 input and $2.00 output. Cached input is lower. Downloaded weights have separate hosting costs and license terms.

$0.40 input / $3 output per 1M tokens
Higher-accuracy flagship according to the vendor.
- 256K context
- Cached input $0.04 per million tokens
- Self-hosted weight options have separate costs
Holo4 35B-A3B API
$0.30 input / $2 output per 1M tokens
Faster mixture-of-experts size.
- 256K context
- Cached input $0.03 per million tokens
- Open weights under Apache 2.0 per release

Assessment
Holo4 strengths and limitations
Where it stands out
- Combines screen, code, and API work within one model family.
- Hosted API and published weights provide deployment choice.
- The launch provides unusually clear per-model token rates and benchmark caveats.
What to consider
- Reported scores depend on the vendor harness and should not be treated as production reliability.
- Long multi-step tasks can still fail or take wrong actions.
- The 27B and 35B-A3B weights have different license terms; check the exact model card.

Holo4 FAQs
Is Holo4 an application?
No. It is a model family exposed through H Models API and published weights for developers and operators.
What interfaces can it use?
H Company describes GUI clicks and typing, code execution, MCP, and ordinary APIs.
Are the weights open?
Weights are on Hugging Face, but license terms differ by model; the 35B-A3B release is described as Apache 2.0.
What should an evaluation measure?
Use representative end-to-end tasks, success and recovery rates, action safety, latency, and total model or hosting cost.
Bottom line
Our Holo4 verdict
Holo4 is a useful candidate for builders whose workflows cross screens and APIs. Its low published token prices are attractive, but benchmark claims and a complex action surface demand hands-on evaluation with isolated accounts before any production automation.
