model, listed separately and graded on its own: [Gemini Developer API](https://www.anchorterminal.com/tools/gemini-api.md) (Model API).\n\n## Assessment\n\nGoogle's strongest model on the same Gemini API as Argon, with a 1M-token budget, function calling and structured output, at an introductory $2 and $10 per million tokens. Paid tier only, sampling parameters are ignored or refused, its launch stage isn't stated, and the price rises to $4 and $20 at a date Google hasn't given.\n\n## Facts\n\n| Field | Value |\n| --- | --- |\n| Vendor | Google (https://ai.google.dev) |\n| Kind | Model API |\n| Category | Model APIs \u0026 inference (https://www.anchorterminal.com/categories/inference) |\n| Endpoint | `https://generativelanguage.googleapis.com/v1beta` |\n| Auth | API key · An `x-goog-api-key` from AI Studio on a project with billing, since Carbon is on the paid tier only, per the Gemini API listing and Google's developer post.

Platform readings (status page, rate limits, keys, SDKs, terms, retention, deprecations) are the Gemini API listing's of 1 November. Google's post saying Carbon is available couldn't be read on 10 November, and the Gemini API pricing page as read showed no Carbon row. No account was made and nothing was called |\n| Model IDs | gemini-4-carbon, and gemini-4-carbon-cyber-permissive for projects approved through the Fairwind Program, which defaults to HIGH thinking |\n| Context | 1,048,576 tokens for input and output together, output including thinking and function calls. 65,536 output tokens by default; a streamed segment returns up to 65,536 and a non-streamed one 32,768 |\n| Inputs and outputs | Text, PDF, Microsoft Office and OpenDocument files, and video (agentic video processing off by default) in; text, function calls and JSON to a schema out |\n| Pricing | $2 input, $10 output per million tokens to start, cached input 95% off, then $4 and $20, per Google's 28 October announcement.

Confidence: medium. Performance and Task success pending (no score, not in the total); the total is Σ(score × weight) ÷ 80 over the 7 assessed categories. \"This run\" is each category's share of the 100 points.\n\n| Category | Weight | This run | Score (0–100) | Points |\n| --- | --- | --- | --- | --- |\n| Reliability | 16% | 20 | 40 | 8.0 |\n| Performance | 10% | pending | pending | n/a |\n| Schema \u0026 documentation | 13% | 16.2 | 85 | 13.8 |\n| Agent ergonomics | 13% | 16.2 | 93 | 15.1 |\n| Security \u0026 auth | 14% | 17.5 | 55 | 9.6 |\n| Payments \u0026 pricing | 10% | 12.5 | 20 | 2.5 |\n| Task success | 10% | pending | pending | n/a |\n| Maintenance \u0026 community | 7% | 8.8 | 83 | 7.3 |\n| Transparency \u0026 trust (editorial 55, provenance 89) | 7% | 8.8 | 72 | 6.3 |\n| Negative events | up to −15 | up to −15 | none recorded | 0 |\n| **Total** | | | | **62.6 → B** |\n\n### Why each score\n\n- Reliability 40 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Status page at aistudio.google.com/status with no readable components or history (10 of 20) and no readable incident record (5 of 30). Rate-limit tiers and spend limits published, per-model limits in AI Studio (5 of 15). Backoff guidance for 429 and 503 and SDK retries (15). No SLA (0). Carbon's launch stage isn't stated in Google's developer post, the Antigravity post or the Cloud developer guide read on 10 November, and the model ID carries no preview label, so half (5 of 10, a judgement call; Argon's GA earned the platform 10). 10 + 5 + 5 + 15 + 0 + 5 = 40.\n- Performance: Pending. Latency is measured per call by our probes, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until the first probe window closes.\n- Schema \u0026 documentation 85 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Discovery document for GenerateContent (20 of 25). llms.txt with Markdown twins (10). The Cloud developer guide says what Carbon takes and refuses, the parameters that return 400 or are ignored, and how to migrate (15 of 20). Structured output to a JSON Schema with some keywords not enforced (10 of 15). Examples and an errors page (15). Dated changelog and model versions (15). 20 + 10 + 15 + 10 + 15 + 15 = 85.\n- Agent ergonomics 93 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Function calling, with forced calls by FunctionCallingConfig on the API (20). Structured output (13 of 15). Implicit caching with durable caching on by default, cached input 95% off, explicit caches not supported, per the Cloud guide read on 10 November (15). 1,048,576 tokens shared between input and output (15). Batch at half price on the platform (10). Python and JavaScript SDKs (10). Error codes with backoff guidance (10 of 15). 20 + 13 + 15 + 15 + 10 + 10 + 10 = 93.\n- Security \u0026 auth 55 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Keys bound to a service account and restricted to the Gemini API, with no scopes and a token accepted in the URL (15 of 30, the platform's deduction). Carbon is on the paid tier only, and Google's terms say paid-tier content isn't used to improve products; AI Studio use under a Google AI Ultra subscription falls under terms we didn't read, so 15 of 20 (a judgement call; the platform's 10 is for its free tier). Abuse retention with no number, and new paid projects store requests by default since 26 October (5 of 15). Request logs for billed projects (15). security.txt and a reward programme, no certification naming the API (5 of 20). 15 + 15 + 5 + 15 + 5 = 55.\n- Payments \u0026 pricing 20 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. No machine payment protocol (0). Introductory prices published in Google's 28 October announcement without a login, $2 and $10, then $4 and $20; the Gemini API pricing page as read on 10 November showed no Carbon row, so the figures rest on the announcement (20). No free tier: Google's developer post puts Carbon on the paid tier (0). A Google account and AI Studio for a key (0). 0 + 20 + 0 + 0 = 20.\n- Task success: Pending. Task success needs the category task suites run through each tool, which haven't run yet, so this run doesn't score it. Its weight is shared across the assessed categories until then. A data provider's data-quality score is published on its listing now and becomes half of this category when it's scored.\n- Maintenance \u0026 community 83 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Released to developers on 10 November 2026, with the platform's changelog (30). Deprecations with earliest dates and no stated minimum notice (4 of 12). Shutdowns in the last 90 days kept to their table (4 of 8). Dated changelog (15). SDK replies not sampled (5 of 10). Current SDKs (15). Runtimes stated (10). 30 + 4 + 4 + 15 + 5 + 15 + 10 = 83.\n- Transparency \u0026 trust 72 (checked 2026-11-10): Model reading for gemini-4-carbon on the Gemini API. Platform facts are the Gemini API listing's (gemini-api, re-read 1 November), carried over as RULES.md allows for a model on an already graded platform. Closed service with clear terms, SDKs Apache-2.0 (15). Paid-tier data isn't used, abuse retention has no number, and request storage is on by default for new paid projects (20 of 30). Deprecations table (15 of 20). Data may be cached anywhere Google has facilities; no subprocessor list checked (5 of 20). Every benchmark figure is Google's own. 15 + 20 + 15 + 5 = 55.\n\nFix list, everything this grade says the listing lacks, the biggest gain first (15 items). What it covers is at https://www.anchorterminal.com/fixes/gemini-4-carbon.md (JSON https://www.anchorterminal.com/fixes/gemini-4-carbon.json). The whole list for a coding agent comes from `POST https://www.anchorterminal.com/api/v1/fix-list` with `{\"listing\": \"gemini-4-carbon\", \"plan\": \"read\"}`, free while the beta runs\n\n### What we couldn't check\n\n- Carbon's launch stage (preview or GA) and when the introductory price ends; neither is stated in what we read\n- Google's 'now available' post on blog.google, which failed to load on 10 November\n- Carbon's row on the Gemini API pricing page, which the page as read didn't show\n- Third-party benchmark runs; every figure here is Google's\n\n### Sources\n\n- robots.txt,

The Lyria RealTime authors stay as they are, on the arXiv paper's author list.\n- Google: LinkedIn https://www.linkedin.com/company/google X https://x.com/Google\n\n### Ownership and investors\n\n- Ownership: Part of Alphabet Inc.\n\n### Getting support\n\n- No support route found yet.\n- Sources: https://www.linkedin.com/in/alicevik/, https://www.linkedin.com/feed/update/urn:li:activity:7462720959725334528/, https://www.linkedin.com/in/tulsee-doshi/, https://about.google/intl/ALL_en/our-story/, https://www.linkedin.com/company/google, https://x.com/Google\n\n## Live (updated 2026-11-10 18:59 UTC)\n\n- Gemini 4 Carbon has gone 0 days without breaking an agent, every day since we started probing it on 10 November 2026.\n- Right now: up, HTTP 404, 71 ms, checked 2026-11-10 18:59 UTC (get on `https://generativelanguage.googleapis.com/v1beta`)\n- Uptime 24h 100.0% (14 probes) · 30 days 100.0% (14 probes) · p50 44 ms · p95 91 ms\n- Vendor status page: not read, no machine-readable status found\n- Always current: https://www.anchorterminal.com/api/v1/live/gemini-4-carbon.json\n\n## Probe metrics\n\nNot measured yet. Our benchmark probes haven't run, so there's no availability, latency or error rate from a run and Performance is pending. Live uptime, where we poll the endpoint, is under Live and doesn't change the score.\n\n## Prices\n\n| Item | Price | Unit | Note |\n| --- | --- | --- | --- |\n| Gemini 4 Carbon input | $2 | per 1M tokens | Introductory; $4 after, date not given |\n| Gemini 4 Carbon cached input | $0.10 | per 1M tokens | 95% off input |\n| Gemini 4 Carbon output | $10 | per 1M tokens | Introductory; $20 after |\n\nAcross all listings: https://www.anchorterminal.com/prices/index.md\n\n## Strengths\n\n- Introductory price of $2 input and $10 output per million tokens, with cached input 95% off\n- 1,048,576 tokens shared between input and output, with long decodes for big outputs\n- Function calling, structured output, Google Search grounding and background execution\n- Thinking levels LOW, MEDIUM (default) and HIGH, and implicit caching on by default\n- The same API, keys and SDKs as Gemini 4 Argon, so switching is a model ID\n\n## Weaknesses\n\n- Paid tier only, with no free tier to try it on\n- temperature, top_p and top_k are ignored, and thinking_budget, MINIMAL, penalties and extra candidates return a 400\n- No explicit context caching, and prefilled model turns aren't accepted\n- The price goes to $4 and $20 after an introduction with no end date given\n- Benchmark figures are Google's own, and the launch stage isn't stated\n\n\n\n## Before you call it (notes for agents)\n\n1. Call generateContent at https://generativelanguage.googleapis.com/v1beta with model gemini-4-carbon and an x-goog-api-key on a billed project\n2. Set thinking_level (LOW, MEDIUM or HIGH) instead of thinking_budget, and don't send temperature, top_p or top_k\n3. Count output against the same 1,048,576-token limit as the input, and set max_output_tokens for long answers\n4. Put static prompt content first so implicit caching applies; explicit caches aren't supported\n5. Use gemini-4-argon for most coding and knowledge work, and Carbon for the hardest long tasks, as Google suggests\n\n## Connect\n\nFirst request:\n\n```bash\ncurl \"https://generativelanguage.googleapis.com/v1beta/models/gemini-4-carbon:generateContent\" \\\n -H \"x-goog-api-key: $GEMINI_API_KEY\" -H \"content-type: application/json\" \\\n -d '{\"contents\":[{\"parts\":[{\"text\":\"hello\"}]}]}'\n```\n\n## Similar tools\n\nRanked by shared capabilities, then score.

The badge or a plain link to this page verifies the listing, from a page on google.com or ai.google.dev or one of their subdomains. It shows the listing is the vendor's and that the vendor knows it's here, and it never changes a grade, rank or review. The vendor sends the page's address to `POST https://www.anchorterminal.com/api/v1/verify` as `{\"slug\": \"gemini-4-carbon\", \"url\": \"…\"}`, or calls the `verify_listing` tool at https://www.anchorterminal.com/mcp.
