AlphaGenome

DeepMind’s AI for Understanding the Genome

What is AlphaGenome?

‍ AlphaGenome is Google DeepMind’s breakthrough AI model purpose-built to decode the genetic “dark matter” of our DNA, especially the mysterious, non-coding regions that make up 98% of the genome. Unlike earlier genome AIs that focused mainly on protein-coding segments, AlphaGenome can process up to 1 million base pairs of DNA in one pass, predicting the molecular impact of both common and rare variants across protein-coding and regulatory sequences. This unified model helps researchers interpret how DNA changes affect gene expression, splicing, and chromatin activity, powers that are foundational for advances in disease research, drug discovery, and personalized medicine.

What are the Risks & Limitations of AlphaGenome

Limitations

Distal Regulatory Gaps: Predictions falter for elements over 100,000 base pairs away.
Cell-Specific Blindness: The model lacks nuance in capturing rare or dynamic cell patterns.
Personal Accuracy Lags: Performance remains lower than models trained on personal data sets.
Environmental Exclusions: DNA logic alone cannot account for external developmental factors.
Complexity Scaling Walls: It predicts molecular outcomes but not complex multi-organ traits.

Risks

Re-identification Risks: Genomic patterns can be traced back to specific individuals easily.
Biosecurity Dual-Use: Capability to design DNA could be misused for pathogen engineering.
Clinical Misapplication: Use in medical diagnosis without validation poses high health risks.
Genetic Discrimination: Data insights could lead to bias in insurance or employment tiers.
Unmonitored Mutational Loops: Automated variant scoring might suggest harmful synthetic edits.

How to Access the AlphaGenome

Manage Team Access and Compliance

Assign roles, permissions, and usage quotas for multiple users. Monitor access logs and ensure secure use of sensitive genomic data. Ensure all usage complies with organizational, ethical, and regulatory standards.

Pricing of the AlphaGenome

AlphaGenome uses a usage‑based pricing model, where costs are determined by the amount of compute your application consumes, rather than a fixed subscription. Charges are tied to the number of tokens processed, both the inputs you send and the outputs the model returns. This flexible billing structure makes it easier for teams to scale costs with actual usage, whether you’re experimenting with prototypes or running high‑volume production workloads.

In typical pricing tiers, input tokens are billed at a lower rate than output tokens because generating responses generally uses more compute. For example, AlphaGenome might cost around $4 per million input tokens and $18 per million output tokens under standard usage plans. Workloads involving extended context or long, detailed outputs will increase overall spend, so refining prompt length and managing verbosity can significantly reduce expenses over time. Because output tokens usually represent most of the usage cost, designing efficient interactions helps keep overall billing predictable.

To further manage spend, many teams use prompt caching, batching, and context reuse to minimize redundant processing and lower the effective token count billed. These strategies are especially valuable in high‑traffic applications such as automated analysis pipelines, conversational agents, or large‑scale data interpretation tools. With usage‑based pricing and thoughtful optimization, AlphaGenome offers a transparent and adaptable cost structure suited for a wide range of AI‑driven solutions without unexpected fees.
