Last fact-checked: August 26, 2026. This page compares the providers’ published specifications and prices. We did not run a controlled live MiniMax M3 versus Claude Opus 5 benchmark for this update, so we do not claim an overall quality winner.
Short answer: MiniMax M3 is the more cost-focused and deployment-flexible option: its standard API list prices are substantially lower, it accepts video as well as text and images, and its weights are available under the MiniMax Community License. Claude Opus 5 is the current flagship of Anthropic’s Opus tier, with native access across the Claude ecosystem, a 1-million-token context window, adaptive thinking enabled by default, and broad availability through Anthropic and major cloud platforms.
Neither is automatically “better” for every workload. Choose based on the quality of your own prompts, total operating cost, required tools, deployment rules, latency targets, and the product surface you intend to use.
Important update: this comparison now uses Claude Opus 5
Anthropic released Claude Opus 5 on July 24, 2026. It is therefore the correct Opus model for a current MiniMax-versus-Claude comparison. Claude Opus 4.8 remains active and available; it is not retired or deprecated as of this fact-check. This page mentions Opus 4.8 only where it matters for migration, compatibility, and safety fallback behavior.
Anthropic recommends Claude Opus 5 as a starting point for complex agentic coding and enterprise work. Claude Fable 5 is Anthropic’s most capable widely released model. Opus 5 remains the appropriate primary Claude comparator here because this article explicitly compares MiniMax M3 with Anthropic’s current Opus tier; it should not be described as Anthropic’s overall highest-capability offering.
MiniMax M3 vs Claude Opus 5: quick verdict
| Priority | Better fit | Why |
|---|---|---|
| Lowest published standard API token price | MiniMax M3 | $0.30 input and $1.20 output per million tokens for requests in the standard tier with up to 512K input tokens. |
| Native Claude product experience | Claude Opus 5 | First-party use in Claude, Claude Code, Cowork, and the native Anthropic API. |

What exactly are we comparing?
“MiniMax versus Claude” can describe several different decisions. MiniMax M3 and Claude Opus 5 are models. Claude, Claude Code, and Cowork are Anthropic products that use Claude models. MiniMax also offers a hosted platform and separate media-generation APIs. A fair decision keeps these layers separate:
- Model capability: response quality on your actual coding, research, writing, vision, and tool-use tasks.
- API service: token price, latency, rate limits, caching, batch support, regional options, reliability, and support.
- Product experience: Claude’s first-party interfaces versus an application you build or connect to MiniMax.
- Deployment: provider-hosted access versus running published M3 weights in your own environment.
- License and governance: the MiniMax Community License versus Anthropic’s hosted-service terms and your cloud agreement.
Using M3 through an Anthropic-compatible endpoint—or configuring it in a Claude Code-style workflow—does not turn M3 into Claude and does not guarantee every Anthropic feature. Compatibility describes parts of the request and response format, not complete product parity.
Claude Opus 5: what changed
Claude Opus 5 is available through Anthropic’s API under the fixed model ID claude-opus-5. Despite the dateless name, Anthropic documents it as a pinned snapshot rather than an automatically changing alias. It is also available across Anthropic’s Claude surfaces and through Amazon Bedrock, Google Cloud, and Microsoft Foundry, subject to each platform’s availability and terms.
Core Opus 5 specifications
- Context: 1 million tokens at standard pricing, without a long-context beta header.
- Synchronous output: up to 128K tokens in the Messages API. A separate 300K-output beta applies only to Message Batches with the required header, so it is not the normal interactive limit.
- Input and output: text and image input, text output, vision, PDF support, Files API support, and server- and client-side tool use.
- Thinking: adaptive thinking is enabled by default. The API’s default effort is
high; supported effort levels arelow,medium,high,xhigh, andmax. - Standard Claude API price: $5 per million input tokens and $25 per million output tokens.
- Deployment model: proprietary hosted access. Anthropic does not list downloadable Opus 5 weights.
Important Opus 5 limitations and exceptions
- Web fetch is not available on Opus 5 at the time of this review. Do not confuse web fetch with every other web or tool feature.
- Priority Tier is not supported for Opus 5. Anthropic offers a separate first-party Fast mode research preview instead.
- Fast mode is not a partner-cloud feature. Anthropic lists it for the first-party Claude API at $10/MTok input and $50/MTok output and reports roughly 2.5× the default speed. That speed figure is a provider claim, not our independent measurement.
- Thinking consumes the output budget.
max_tokenscovers thinking and the visible answer together, and thinking tokens are billed as output tokens. - Beta status is feature-specific. Computer use moved out of beta on August 19, 2026 as
computer_toolset_20260801and no longer requires a beta header. Selected server-side fallback controls and earlier tool versions can still have separate beta requirements, so follow the documentation for the exact tool version used.
On Claude.ai, Claude Code, and Cowork, Anthropic may route certain high-risk offensive cybersecurity requests from Opus 5 to Opus 4.8. API fallback is opt-in. Anyone benchmarking these models should record the model actually used and avoid treating a fallback response as an Opus 5 result.
MiniMax M3: the relevant facts
MiniMax released M3 on June 1, 2026. The hosted model ID is MiniMax-M3. MiniMax describes it as a mixture-of-experts model with approximately 428 billion total parameters and 23 billion active parameters during inference. These are architecture specifications from MiniMax, not proof of response quality.
- Context: up to 1 million tokens shared by input and output. MiniMax says the API guarantees at least 512K, so the 1M figure should not be read as a guaranteed 1M input allowance for every request.
- Output: 131,072 tokens recommended and 524,288 documented as the maximum.
- Multimodal input: text, images, and video. The M3 text endpoint returns text, reasoning content, and tool requests; it is not the endpoint for generating images or videos.
- Hosted API: OpenAI-compatible Chat Completions and Responses routes plus an Anthropic-compatible Messages route.
- Weights: official full and MXFP8 repositories are published under the custom MiniMax Community License.
“Open-weight” is the accurate description. “Unrestricted open source” is not. Commercial users should review the current license directly: it includes attribution, notice, revenue-threshold, and prohibited-use provisions. This page is not legal advice.

API pricing: MiniMax M3 vs Claude Opus 5
The table below compares pay-as-you-go API list prices, not consumer subscriptions or bundled token plans. MiniMax selects its price band using the number of input tokens in each request, including cache-hit tokens.
| API option | Input / MTok | Output / MTok | Cache read / MTok |
|---|---|---|---|
| MiniMax M3 Standard, up to 512K input | $0.30 | $1.20 | $0.06 |
| MiniMax M3 Standard, above 512K input | $0.60 | $2.40 | $0.12 |
| MiniMax M3 Priority, up to 512K input | $0.45 | $1.80 | $0.09 |
| MiniMax M3 Priority, above 512K input | $0.90 | $3.60 | $0.18 |
| Claude Opus 5 Standard | $5.00 | $25.00 | $0.50 |
| Claude Opus 5 Batch | $2.50 | $12.50 | See Anthropic’s cache rules |
| Claude Opus 5 Fast mode research preview | $10.00 | $50.00 | See Anthropic’s cache rules |
Anthropic also lists Opus 5 prompt-cache write rates of $6.25/MTok for a five-minute cache and $10/MTok for a one-hour cache. Cache hits and refreshes cost $0.50/MTok. MiniMax’s current M3 table lists cache-read pricing but does not list a separate cache-write price, so we do not invent one.
Illustrative monthly token calculation
Suppose an application processes 100 million uncached input tokens and generates 20 million output tokens. Ignoring caching, batch discounts, tools, taxes, and regional or cloud charges:
| Service | Calculation | Illustrative cost |
|---|---|---|
| MiniMax M3 Standard, requests at or below 512K input | (100 × $0.30) + (20 × $1.20) | $54 |
| MiniMax M3 Standard, requests above 512K input | (100 × $0.60) + (20 × $2.40) | $108 |
| Claude Opus 5 Standard | (100 × $5) + (20 × $25) | $1,000 |
This arithmetic demonstrates list-price differences only. It does not show which model completes the task correctly, how many retries an application needs, how much reasoning output is generated, or which service has better latency. The cheapest token can be more expensive if it requires more tokens or human correction; the higher-priced token can be poor value if a less expensive model already meets the quality threshold.
Coding and agent workflows
Claude Opus 5 has the strongest integration advantage when a team specifically wants Anthropic’s first-party workflow. It is available in Claude Code and across Anthropic’s broader agent tooling. The native Messages API exposes Anthropic’s current tool and thinking features directly, while the major-cloud routes can simplify procurement for organizations already standardized on those platforms.
MiniMax M3 supports function tools, interleaved thinking, and multi-turn tool loops. MiniMax also documents how to configure M3 for Claude Code through its Anthropic-compatible endpoint. That can be useful for cost-sensitive coding workflows, but it is still M3 served by MiniMax—not Claude Opus 5—and feature behavior can differ.
Why published coding scores are not enough
MiniMax and Anthropic each publish benchmark results under their own test configurations. The M3 launch predates Opus 5 and does not provide a controlled head-to-head test against it. Anthropic’s Opus 5 launch results use Anthropic’s evaluation settings and are not an independent MiniMax comparison. Replacing an older Claude label in a historical chart with “Opus 5” would be inaccurate.
For production selection, build a private test set from real work: repository-scale bug fixes, code review, migration tasks, tool calls, long-running agents, and cases with known correct answers. Measure success rate, review time, retry rate, total tokens, latency, and cost per accepted task—not just cost per token.
Reasoning behavior and fair API tests
The models do not share one universal “thinking default,” and MiniMax M3 itself changes behavior by endpoint. A comparison that ignores these defaults can accidentally give one model more reasoning time or output budget than the other.
| API surface | Behavior when the reasoning setting is omitted |
|---|---|
| MiniMax OpenAI-compatible Chat Completions | Adaptive thinking is enabled by default. |
| MiniMax Anthropic-compatible Messages | Thinking is off by default; use the documented adaptive setting to enable it. |
| MiniMax OpenAI-compatible Responses | Reasoning is off by default. Non-none effort values enable adaptive thinking but do not tune M3’s reasoning depth. |
| Anthropic Messages with Claude Opus 5 | Adaptive thinking is enabled by default; effort defaults to high. |
For a reproducible evaluation, record the endpoint, model ID, reasoning configuration, output ceiling, tools, system prompt, temperature-related settings, timestamp, and actual returned model. Use the same stopping rules and score the final task result. Do not assume similarly named effort values have identical computational meaning across providers.
Current Opus 5 API constraints also matter when validating an integration: disabling thinking is accepted only at high effort or below; combining disabled thinking with xhigh or max returns an error. Non-default temperature, top_p, or top_k values are not accepted, and assistant prefilling is unsupported.
Long context and output limits
Both providers advertise a 1-million-token context figure, but it should not be simplified to “one million input tokens plus the output.” Context is a shared budget that includes more than the visible user prompt.
- MiniMax M3: the 1M figure covers input and output together. MiniMax documents at least 512K guaranteed capacity, and its pricing increases when a request exceeds 512K input tokens.
- Claude Opus 5: the 1M window includes conversation history, system content, tool definitions, images, documents, output, and thinking. Its standard synchronous output ceiling is 128K.
M3’s higher documented output maximum may matter for unusually large structured generation, but “maximum” does not mean every task should use it. Very long outputs increase latency, cost, validation burden, and the chance of downstream truncation. MiniMax’s own recommended output setting is 131,072 tokens.
Multimodal input and media generation
| Capability | MiniMax M3 | Claude Opus 5 |
|---|---|---|
| Text input | Yes | Yes |
| Image input | Yes | Yes |
| Video input | Yes | Not listed as a direct Opus 5 modality |
| PDF/document support | Not treated here as a native M3 modality; verify the exact upload or preprocessing workflow | PDF and Files API support documented |
| Text output | Yes | Yes |
| Native image or video output from this model endpoint | No | No |
MiniMax offers separate image, video, speech, and music products, but those capabilities should not be attributed to the M3 text model. Likewise, features in the Claude application or tool ecosystem should not be mistaken for a native Opus 5 output modality.
Deployment, weights, and licensing
Deployment is one of the clearest differences. M3’s weights are published, so qualified teams can evaluate self-hosting, private-cloud deployment, quantization, and custom serving. Anthropic provides Opus 5 as a hosted proprietary model through its own services and supported cloud partners; it does not list official downloadable model weights.
Self-hosting M3 should not be described as lightweight. The official full repository is roughly 854GB, while MiniMax’s MXFP8 repository is roughly 444GB. Repository storage size is not the same as runtime memory. Actual hardware depends on quantization, context length, concurrency, KV cache, multimodal inputs, and the serving framework. The fact that roughly 23B parameters are active per inference step does not mean only 23B parameters need to be stored.
Before commercial deployment, read the current MiniMax Community License. It includes requirements such as “Built with MiniMax M3” attribution, a commercial-use notice, a revenue threshold for prior written authorization, and prohibited-use conditions. Legal and procurement teams should review the exact text rather than relying on a comparison article.
Privacy, retention, and enterprise review
Do not infer privacy guarantees from the model name alone. Data retention can differ by consumer app, API account, cloud provider, feature, geography, contract, and whether tools such as web access or code execution are used.
- Anthropic lists Opus 5 as compatible with eligible zero-data-retention arrangements, but that does not make every Claude surface or account zero-retention by default.
- MiniMax API users should review MiniMax’s current platform terms, privacy terms, data location, logging controls, and enterprise agreement for the service they actually use.
- Self-hosting M3 can increase infrastructure control, but the operator becomes responsible for access control, logging, patching, model governance, abuse prevention, and data security.
For regulated workloads, request written answers from the provider or cloud partner and validate them against your organization’s legal, security, and compliance requirements.
Migrating from Claude Opus 4.8 to Opus 5
Opus 4.8 remains active, so there is no basis for describing it as already retired. Anthropic’s migration guide provides a direct path from Opus 4.8 to Opus 5. Start with a controlled model-ID change, then retest behavior and budgets.
| Check | Required review |
|---|---|
| Model ID | Replace claude-opus-4-8 with claude-opus-5 in a test environment first. |
| Thinking default | Opus 5 enables adaptive thinking by default; Opus 4.8 did not unless configured. Expect different output-token use and latency. |
| Output budget | Revisit max_tokens because it covers both thinking and the visible answer. |
| Thinking controls | Do not combine disabled thinking with xhigh or max effort. |
| Prompt caching | The minimum cacheable prompt is 512 tokens on Opus 5, down from 1,024 on Opus 4.8. Recheck cache behavior near that boundary. |
| Feature dependencies | Opus 5 does not currently support web fetch or Priority Tier. Validate alternatives before switching production traffic. |
| Quality and safety | Rerun regression, tool-use, latency, cost, and refusal tests; record any fallback model used. |
At the time of this review, Anthropic’s lifecycle table for Anthropic-operated platforms lists both models as Active and states that Opus 4.8 will not be retired before May 28, 2027. Partner-operated cloud schedules can differ. Lifecycle dates can change, so check the relevant provider’s model table before planning a long migration window.
Where other Claude models fit
Opus 5 is the right primary comparison for this page because the search intent is MiniMax versus Anthropic’s current Opus tier. It is not Anthropic’s only current model.
| Claude model | Documented position | Context / sync output | Standard input / output per MTok |
|---|---|---|---|
| Claude Fable 5 | Anthropic’s most capable widely released model | 1M / 128K | $10 / $50 |
| Claude Opus 5 | Recommended starting point for complex agentic coding and enterprise work; current Opus tier | 1M / 128K | $5 / $25 |
| Claude Sonnet 5 | Speed-and-intelligence balance | 1M / 128K | $2 / $10 standard pricing |
| Claude Haiku 4.5 | Fast, lower-cost tier | 200K / 64K | $1 / $5 |
These prices and model positions were reverified on August 26, 2026. On August 10, Anthropic made Sonnet 5’s $2/$10 introductory rate its standard price and cancelled the previously scheduled September 1 increase to $3/$15. Check Anthropic’s current pricing before a procurement decision because prices, discounts, and regional or cloud-platform terms can change.
How to choose
| Choose MiniMax M3 when… | Choose Claude Opus 5 when… |
|---|---|
| Raw API token cost is a major constraint. | You want the native Claude, Claude Code, or Cowork experience. |
| You need direct video input in the model API. | You need first-party Anthropic tools and their documented integrations. |
| You require published weights or want to evaluate self-hosting. | Your procurement path is Anthropic, Bedrock, Google Cloud, or Microsoft Foundry. |
| You need a documented output ceiling above 128K. | Your existing application is built around the native Messages API and Claude behavior. |
| You can validate a custom license and operate substantial model infrastructure. | You prefer managed proprietary access over operating a very large model. |
| Your own evaluation shows M3 meets the required quality threshold. | Your own evaluation shows Opus 5’s task success justifies its higher list price. |
A fair evaluation protocol
- Define the task: use real examples with a known outcome and a clear acceptance rubric.
- Freeze the configuration: record model IDs, endpoints, prompts, tools, reasoning settings, output limits, and dates.
- Control context: send the same relevant files and instructions, accounting for provider-specific formatting.
- Run multiple trials: one response is not a reliability estimate. Include difficult and failure-prone cases.
- Score outcomes blindly where practical: assess correctness, completeness, tool-call validity, edit quality, and safety without favoring a provider name.
- Measure operational cost: include retries, thinking tokens, cache behavior, tool charges, review time, latency, and failed tasks.
- Verify the serving path: note cloud region, service tier, and any fallback model.
- Retest before launch: model behavior, prices, and platform features can change after this article’s fact-check date.
Final verdict
MiniMax M3 has a clear published-price advantage and offers capabilities Opus 5 does not list, including direct video input and downloadable weights. It is compelling for cost-sensitive APIs, long-output workflows, and teams with a real requirement—and the infrastructure—to operate an open-weight model.
Claude Opus 5 is the stronger ecosystem choice for teams that want Anthropic’s current Opus experience across Claude products, the native Messages API, advanced managed tooling, and established cloud procurement routes. Its adaptive-thinking defaults and migration differences require careful testing, especially for applications coming from Opus 4.8.
There is no evidence-based reason to declare one universal quality winner without a controlled, current M3-versus-Opus-5 evaluation. The responsible decision is to test both on the work that matters, then compare accepted-task cost rather than marketing claims or token price alone.
Frequently asked questions
Is MiniMax M3 better than Claude Opus 5?
No universal winner has been established by a controlled, independent, like-for-like test. M3 has lower published standard API prices, video input, downloadable weights, and a higher documented maximum output. Opus 5 offers native Anthropic products, managed tooling, and broad cloud availability. Test your own tasks.
Which API is cheaper, MiniMax M3 or Claude Opus 5?
At list price, MiniMax M3 is cheaper per standard input and output token. For requests with up to 512K input tokens, M3 Standard is $0.30/MTok input and $1.20/MTok output, versus $5 and $25 for Opus 5. Total cost still depends on token volume, retries, caching, tools, batch use, latency, and task success.
Do MiniMax M3 and Claude Opus 5 both support one million tokens?
Both document a 1M-token context figure, but the budgets are not “1M input plus output.” M3’s figure combines input and output and MiniMax states at least 512K is guaranteed. Opus 5’s total context includes the conversation, system content, tools, media, output, and thinking.
Can MiniMax M3 be used with Claude Code?
MiniMax documents a Claude Code configuration that routes requests to M3 through MiniMax’s Anthropic-compatible endpoint. This can support a Claude Code-style workflow, but M3 remains a MiniMax model and does not gain complete Claude or Anthropic API feature parity.
Does MiniMax M3 generate images or videos?
No. The documented M3 text-model endpoint accepts text, images, and video as input and returns text, reasoning content, or tool requests. MiniMax provides separate models and APIs for media generation.
Is Claude Opus 5 Anthropic’s most capable model?
Not overall. Anthropic recommends Opus 5 for complex agentic coding and enterprise work, while it describes Claude Fable 5 as its most capable widely released model. Standard Claude API list prices are $5/$25 per million input/output tokens for Opus 5 and $10/$50 for Fable 5.
Has Claude Opus 4.8 been retired?
No. As of August 26, 2026, Anthropic lists Opus 4.8 as Active. Opus 5 is the current Opus model and the correct primary reference for this comparison, while 4.8 remains relevant for migration and some documented fallback behavior.
Can I self-host MiniMax M3 or Claude Opus 5?
MiniMax publishes M3 weights under its Community License, so self-hosting is possible but requires substantial storage, compute, and operational expertise. Anthropic does not publish official downloadable Opus 5 weights; access is hosted through Anthropic and supported cloud platforms.
Is the demo on this site a MiniMax M3 versus Opus 5 benchmark?
No. A site demo or single short prompt is not a controlled cross-provider benchmark unless it exposes and records both exact model IDs, settings, prompts, tools, outputs, dates, repetitions, and scoring rules. Use the evaluation protocol above for a defensible comparison.
