The short version
- Only Deep Code has a free tier, so it costs nothing to try first.
- Each has a real cost: Deep Code model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.; Zeta it competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- They diverge on capability: Deep Code covers DeepSeek-backed agent, Zeta covers Tachyon card processing.
- Prices and features above were last checked on 15 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Deep Code
- Model choice is narrow. Bring your own key covers DeepSeek-V4-Pro and Flash plus the GLM and Mimo coding plans, and no frontier model from OpenAI, Anthropic or Google.
- The Pro tier caps included usage at 100 Pro Credits per day rather than offering an unmetered plan.
- Bring your own key is a paid feature, so the free tier cannot be pointed at your own DeepSeek account.
- Desktop only, with no editor extension, web version or team seat management as of September 2026.
- A small, young vendor with no independent review coverage yet, so there is nothing outside the vendor's own site to corroborate the cost claim.
Zeta
- It competes against card processors with decades of production track record, and in card processing an outage is a public event, so a shorter operational history is a genuine risk factor rather than a technicality.
- Contracts are enterprise scale and quoted with volume minimums, which puts it out of reach of small issuers who would otherwise benefit most from modern tooling.
- A card portfolio migration runs twelve to twenty four months at minimum, during which the issuer runs two platforms and pays for both.
- Zeta is a processor rather than a licence holder, so network membership, BIN sponsorship and regulatory obligations remain entirely with the issuer.
- Public references for large live United States production volumes are fewer than the announcements imply, so diligence should insist on active account counts and uptime history rather than partnership press releases.

Answered from the vendors’ own pages
Deep Code: Which models does Deep Code run on?
DeepSeek V4 family models, with the vendor's headline built around DeepSeek V4.1. The free tier's included credits run on DeepSeek-V4-Flash. Paid users bringing their own key can also use DeepSeek-V4-Pro, the GLM Coding Plan and the Mimo Coding Plan.
SourceZeta: Which Zeta is this?
The banking technology company founded by Bhavin Turakhia, which builds the Tachyon card processing and core banking platform. Not any similarly named payroll or accounting product.
Deep Code: What does Deep Code cost?
There are two tiers. Free is $0 per month and includes session management, the file explorer, snippets, voice input and weekly free credits on DeepSeek-V4-Flash. Pro is $5 per month and adds 100 daily Pro Credits plus bring-your-own-key support for multiple models.
SourceZeta: What is its strongest use case?
United States credit card issuing and processing, where legacy platforms make product changes slow and expensive.
Deep Code: Do I need my own API key to use it?
No. The free tier includes weekly credits and needs no credit card, so the app works without a key. Bring your own key is available on the $5 per month Pro tier and covers DeepSeek-V4-Pro, DeepSeek-V4-Flash, the GLM Coding Plan and the Mimo Coding Plan.
SourceZeta: Does Zeta provide the BIN or licence?
No. It processes. Network membership, BIN sponsorship and regulatory obligations stay with the issuer.
Deep Code: Which operating systems does it run on?
Windows, macOS and Linux. It is a desktop application rather than an editor extension, so it runs alongside whatever editor you already use.
SourceDeep Code: Is the 95 percent cheaper claim independently verified?
No. It is the vendor's own figure, based on DeepSeek token pricing against frontier model pricing. Actual savings depend on which model you compare against and how much of your usage falls inside the included credits.
