Corollary vs Tamarind Bio
Tamarind Bio runs protein and molecular models in the browser or by API, with a free tier of a few jobs a month and paid plans on request. Corollary runs 145 open models too, inside a free research agent that also does the bioinformatics around them.
The short answer
Tamarind Bio is a model-hosting platform for drug discovery: pick a model, give it inputs, get the result, in the browser or through an API, SDK, CLI or MCP server. Its catalogue of protein and molecular models is larger than ours, and its paid plans are aimed at companies running models in volume.
Corollary runs open models as well, but most people use them through the research agent, which prepares the inputs, runs the model, reads the confidence back and carries on — into a database lookup, a sequence analysis or a pipeline. It is free, and a non-commercial research demonstration.
Choose Tamarind for the widest model catalogue, programmatic runs at scale and commercial terms. Choose Corollary when a model run is one step of a larger analysis, or when you want an agent to do the work around it, free.
Side by side
- What it is
- CorollaryA research agent with a Linux machine of its own, and a library of open scientific models, programs, databases and pipelines it runs for you.
- Tamarind BioA platform for running AI and simulation models for drug discovery, from the browser or by API.[1]
- How you use it
- CorollaryIn the browser, with a free account or signed out. Nothing to install. Also a developer API and an MCP server.
- Tamarind BioA web app, plus a REST API, Python SDK, CLI and MCP server.[3]
- Price
- CorollaryFree. 30,000 credits a month with an account, 1,000 signed out; database queries never use credits.
- Tamarind BioFree: 10 jobs a month on every model, with runtime limits. Premium and Enterprise prices are not published.[2]
- Commercial use
- CorollaryNot permitted. Corollary is a non-commercial research demonstration, with no warranty or support.
- Tamarind BioOn paid plans, under a separate agreement. The free tier's terms restrict commercial use unless approved.[4][7]
- Where the work runs
- CorollaryOn our servers: a Linux machine per conversation, and jobs of up to 32 cores, 256 GiB of memory and 24 hours for long runs.
- Tamarind BioTamarind's GPUs, metered in hours weighted against a T4 GPU.[6]
- Scientific AI models
- Corollary301 models in the library, 145 of them run here — GPU included, with no setup and no key of your own.
- Tamarind BioMore than 300 tools, among them ESMFold, Boltz-2, RFdiffusion, ProteinMPNN, Chai-1 and BindCraft.[1][11]
- Programs and pipelines
- Corollary43 bioinformatics programs installed or run as jobs, and 143 nf-core pipelines.
- Tamarind BioMulti-tool pipelines, fine-tuning, custom tools, and a portal for ordering wet-lab assays.[10]
- Databases
- Corollary53 public databases queried live, with no API key of your own.
- Tamarind BioNot a database service: the inputs are your sequences, structures and molecules.
- Language model
- CorollaryChosen and paid for by Corollary. No API key of your own.
- Tamarind BioA Protein Design Agent for binder campaigns, on the Premium plan. The language model behind it is not named.[5]
- Open source
- CorollaryNo. The service is closed source; the models, programs and pipelines it runs are open.
- Tamarind BioNo.
- Your files
- CorollaryUploaded to our servers and kept in the conversation's workspace. Some of our processors are in the United States.
- Tamarind BioNot used for training and not sold; processed in the United States.[7]
Tamarind Bio's column is from its own public pages, read on 24 October 2026; the numbers link to them below. Corollary's figures are counted from the platform itself and each one links to the page that lists them.
Where Tamarind Bio is the better choice
- A larger catalogue of protein and molecular models, with batch runs and fine-tuning.[1][10]
- A full API, SDK, CLI and MCP server with webhooks, built for running models in volume.[3][8]
- Commercial plans, with custom model hosting and SAML SSO for enterprises.[2]
- Wet-lab assays from partners such as Adaptyv and Ginkgo, ordered from the same place.[10]
- It states SOC 2 compliance, and counts 8 of the top 20 pharma companies among its users.[1][9]
Where Corollary is the better choice
- An agent that does the work around the model: it prepares inputs, runs the model, reads the confidence scores back and explains them — on the free plan.
- Biology beyond protein models: 43 bioinformatics programs, 143 nf-core pipelines and 53 public databases, in the same conversation.
- 30,000 free credits a month, renewed every month, to spend on the 145 models that run here.

Ask in plain language. The agent works on a Linux machine of its own: it installs and runs what the job needs, keeps every file, and reads the results back with the numbers explained.
Questions
Is Corollary a free alternative to Tamarind Bio?
Corollary is free: 30,000 credits a month with an account, and database queries never use credits. It is a non-commercial research demonstration, so it is not an alternative for commercial work — for that, Tamarind Bio or one of the other options below may be the right choice.
Is Tamarind Bio free?
It has a free tier with a fixed number of jobs a month on every model, with runtime limits, meant for academics and individuals without proprietary data; its terms restrict commercial use on that tier. Paid plans are priced on request.
Can I run ESMFold online for free?
Yes. On Corollary, open the ESMFold page or ask the research agent, and the prediction runs on the free plan, with no GPU of your own, and the confidence is explained. Tamarind and others host it too.
