Free can mean a client, a small inference allowance, or a trial with restricted output rights. Choose the task first, then read the catch on the same card. Use the cost-saving playbook to count setup, retries and review time; the October buying guide owns dated paid choices.

October picks: limits and data

Sources checked October 21, 2026. Start with a small task and the exact route above. These are editorial starting points based on published capabilities, not a tested ranking. OpenCode and OpenRouter list free model inference; NVIDIA offers development access under separate trial terms. A listing does not guarantee account access, capacity or a continuing offer.

OpenRouter limits: the current :free policy lists 20 requests/minute and 50/day for the lower purchased-credit tier. A roughly $10 all-time credit purchase raises the documented daily ceiling to 1,000; that higher tier requires payment, and the documentation notes a fee-rounding threshold adjustment. Limits are shared, not multiplied by extra keys/accounts; provider capacity can still reject a request. The model catalog supplies the two routes’ token prices and capabilities. A context window is not a daily allowance.

NVIDIA trial boundary: NVIDIA advertises free development access; its catalog lists both candidates. The API Trial Terms, sections 1.2–1.4, limit access to trial purposes and exclude both the service and generated content from production. Trial credits, duration and request capacity must be checked for your account; no universal numeric allowance is established here.

Before sending data: OpenCode says this Free model’s provider has zero retention and does not train on submissions; read the Console notice below and the route-specific privacy guide. OpenRouter provider training and retention policies vary, with separate free/paid routing settings; training opt-out is not a blanket no-retention guarantee. NVIDIA’s trial excludes confidential input, restricts personal data unless expressly allowed, and permits input/output use for model improvement. Use public or synthetic material for an initial trial.

The DeepSeek catalog configuration supplies its limits. This scoped check ran no account, inference, quality, latency or throughput tests and does not renew older directory entries or the October 19 incident capture.

Console security notice — sources captured October 19: OpenCode says a breach affected 1.4% of Console users, a subset with external providers linked, and says affected users were emailed. Read the credential-route distinction and verification limits before linking a provider. Direct local BYOK and Console-stored linked credentials are different paths; neither is declared proven safe here.

Other coding/API entries retain their October 3 documentation check; creative audio/video entries retain October 13. Task fits are editorial suggestions. Account access, inference, latency, quotas and accepted-result outcomes were not tested.

Creative audio and video

Documentation checked 13 October 2026; no account, generation or export tests. Generation credits, downloadable songs and permitted commercial use are different limits. For Google’s routes, start with the Lyria music guide or Flow video guide. The resources below are access checks, not comparative quality reviews.

Suno: song sketches with a separate download cap

Suno’s Free plan offers 50 generation credits per day for personal, non-commercial use. Credits reset rather than accumulate. The download FAQ separately describes up to seven lifetime trial downloads, not a monthly allowance. Check your unused downloads and any card-backed trial’s renewal terms before signing up.

For publication, check the track’s eligibility and permitted paid-plan download in the rights help. Upgrading alone is not a blanket retroactive licence; qualifying remixes of your own song have separate conditions. Copyright is not guaranteed. The privacy policy permits training; paid consumer exemption was not established. Private/Link Only means unlisted sharing, not an authenticated audience.

Higgsfield: hosted video tools or a separately billed API

Choose the website for its creative interface or the API for integration. Website credits and API dollars are separate. The launch page advertises $15 after business-email verification and adding a card; its seven-day label establishes no calendar cutoff or personal grant. Promotion availability and promotional-balance expiry remain unresolved. API top-ups start at $5; check optional auto-top-up before paying.

Website watermark rules do not establish API export rules, and upgrading does not remove old marks. Consumer commercial permission is subject to upstream restrictions; Seedance-specific exclusions remain unresolved. Consumer privacy permits training. The API terms describe a prospective Workspace opt-out, not a universal upstream-model exemption.

Seedance: choose the video provider before checking rights

Seedance 2.5 is a model family, not a shared allowance or licence. Its provider routes differ:

  • Dreamina website: a free-start banner conflicts with subscriber, age and region eligibility. Free entitlement, numeric allowance and card conditions remain unresolved. The checked general terms restrict commercial use with possible supplemental permissions and direct US users to separate terms; check your regional contract. Privacy terms permit improvement/training.
  • Higgsfield website/API: website model help lists Pro/Plus and above; the API endpoint is separate. Apply the payment, export and data checks above to your chosen route.
  • BytePlus ModelArk: check the model documentation and activation terms for API use. Official indexed text indicates separate API and Playground terms, with Playground output limited to internal/private/non-commercial use. Those access-limited passages remain leads for a full contract read, not commercial clearance.

No current Lumina bonus or expired Dreamina promotion is recommended here. For any route, verify input rights and export permission before publishing; a free-start banner establishes neither.

Check the data path

Free or low-cost inference still needs a data-path decision. DeepSeek’s 2025 database exposure separates model capability, provider infrastructure, data terms and sharing controls. That historical record establishes neither present exposure nor present safety.

Gemini data exceptions

Google’s terms apply paid-service data handling throughout the EEA, Switzerland and UK, including unpaid quota. Elsewhere, Studio qualifies when your account has access to an actively billed Cloud project or is a Workspace enterprise account; API access qualifies through an actively billed project. Paid-service prompts/responses are not used for product improvement, but safety/legal logging remains. Serving API clients to users in those European regions requires Paid Services.

For Groq, use Data Controls to check zero-retention settings; persistence features and abuse/reliability exceptions make an unconditional privacy promise inaccurate. For OpenRouter, review both its own settings and the selected provider’s policy. Training opt-out is not a blanket no-retention guarantee.

For proprietary work, a free price alone is insufficient permission. In particular, NVIDIA’s trial terms exclude confidential inputs and production use of the service and generated content. The Kimi access guide separates model listings from tested entitlements.

FAQ

What is the best free AI coding tool right now?

Choose by task and restriction: a free client may still need paid inference, and a free hosted allowance may have data-use or trial limits. This directory does not rank an untested winner.

Where can I trial a coding API before paying?

Groq, Gemini API and OpenRouter document limited free access. NVIDIA is an internal-evaluation trial: neither the service nor its generated content may be used in production under the trial terms. Account eligibility remains untested.

Is Qwen still free on OpenCode?

Check the dated free-priced Zen roster in the OpenCode guide. A model name or an old promotion does not establish a current free entitlement.

Is Kimi still free anywhere?

NVIDIA lists Kimi K3, but its trial listing does not establish a universal no-payment quota. The trial service and generated content are excluded from production; use the Kimi access guide for current route boundaries.

What should I use if I want local or on-device AI?

Use the local-inference guide to choose a runtime and model that fit your hardware. Local inference avoids hosted API charges, but hardware, electricity, setup and model-license constraints remain.

Are ChatGPT Free and Claude Free good enough for coding?

They can help with occasional questions. For repeatable coding work, compare the workflow, allowance and data rules in this directory, then test a bounded task. No comparative outcome was measured here.

For OpenCode’s client and BYO-provider choices, use the client overview. The DeepSeek Free offer has an October 17 check; the broader dated Zen roster retains October 3. For a paid upgrade, return to the buying guide and evaluate cost per accepted result.
